英文文献：Aircraft Communications Addressing andReporting SystemAircraft Communications Addressing and Reporting System (ACARS) is a digital datalink system for transmission of short, relatively simple messages between aircraft and ground stations via radio or satellite. The protocol, which was designed by ARINC to replace their VHF voice service and deployed in 1978,[1]uses telex formats. SITA later augmented their worldwide ground data network by adding radio stations to provide ACARS service. Over the next 20 years, ACARS will be superseded by the Aeronautical Telecommunications Network (ATN) protocol for Air Traffic Control communications and by the Internet Protocol for airline communications.Contents1.

External linksHistory of ACARSPrior to the introduction of datalink, all communication between the aircraft (i.e., the flight crew) and personnel on the ground was performed using voice communication. This communication used either VHF or HF voice radios, which was further augmented with SATCOM in the early 1990s. In many cases, thevoice-relayed information involves dedicated radio operators and digital messages sent to an airline teletype system or its successor systems.Introduction of ACARS systemsThe Engineering Department at Aeronautical Radio, Inc (ARINC), in an effort to reduce crew workload and improve data integrity, introduced the ACARS system in July 1978. The first day operations saw about 4000 transactions. A few experimental ACARS systems were introduced earlier but ACARS did not start to get any widespread use by the major airlines until the 1980s.The original ARINC development team was headed by Crawford Lane and included Betty Peck, a programmer, and Ralf Emory, an engineer. The terrestrial central site, a pair of Honeywell Level 6 minicomputers, (AFEPS) software was developed by subcontractor, Eno Compton of ECOM, Inc.Although the term ACARS is often taken into context as the datalink avionics line-replaceable unit installed on the aircraft, the term actually refers to a complete air and ground system. The original meaning was Arinc Communications Addressing and Reporting System .Later, the meaning was changed to Airline Communications, Addressing and Reporting System.On the aircraft, the ACARS system was made up of an avionics computer called an ACARS Management Unit (MU) and a Control Display Unit (CDU). The MU was designed to send and receive digital messages from the ground using existing VHF radios.On the ground, the ACARS system was made up of a network of radio transceivers, managed by a central site computer called AFEPS (Arinc Front End Processor System), which would receive (or transmit) the datalink messages, as well as route them to various airlines on the network.The initial ACARS systems were designed to the ARINC standard 597. This system was later upgraded in the late 1980s to the ARINC 724 characteristic. ARINC 724 addressed aircraft installed with avionics supporting digital data bus interfaces. This was subsequently revised to ARINC 724B, which was the primary characteristic used during the 1990s for all digital aircraft. With the introduction of the 724B specification, the ACARS MUs were also coupled with industry standard protocols for operation with flight management system MCDUs using the ARINC 739 protocol, and printers using the ARINC 740 protocol. The industry has defined a new ARINC characteristic, called ARINC 758, which is for CMU systems, the next generation of ACARS MUs.OOOI eventsOne of the initial applications for ACARS was to automatically detect and report changes to the major flight phases (Out of the gate, Off the ground, On the ground, and Into the gate); referred to in the industry, as OOOI. These OOOI events were determined by algorithms in the ACARS MUs that used aircraft sensors (such as doors, parking brake and strut switch sensors) as inputs. At the start of each flight phase, the ACARS MU would transmit a digital message to the ground containing the flight phase, the time at which it occurred, and other related information such as fuel on board or origin and destination. These messages were primarily used to automate the payroll functions within an airline, where flight crews were paid different rates depending on the flight phase.Flight management system InterfaceIn addition to detecting events on the aircraft and sending messages automatically to the ground, initial systems were expanded to support new interfaces with other on-board avionics. During the late 1980s and early 1990s, a datalink interface between the ACARS MUs and Flight management systems (FMS) was introduced. This interface enabled flight plans and weather information to be sentfrom the ground to the ACARS MU, which would then be forwarded to the FMS. This feature gave the airline the capability to update FMSs while in flight, and allowed the flight crew to evaluate new weather conditions, or alternate flight plans.Maintenance Data DownloadIt was the introduction in the early 1990s of the interface between the FDAMS / ACMS systems and the ACARS MU that resulted in datalink gaining a wider acceptance by airlines. The FDAMS / ACMS systems which analyze engine, aircraft, and operational performance conditions, were now able to provide performance data to the airlines on the ground in real time using the ACARS network. This reduced the need for airline personnel to go to the aircraft to off-load the data from these systems. These systems were capable of identifying abnormal flight conditions and automatically sending real-time messages to an airline. Detailed engine reports could also be transmitted to the ground via ACARS. The airlines used these reports to automate engine trending activities. This capability enabled airlines to better monitor their engine performance and identify and plan repair and maintenance activities.In addition to the FMS and FDAMS interfaces, the industry started to upgrade the on-board Maintenance Computers in the 1990s to support the transmission of maintenance related information real-time through ACARS. This enabled airline maintenance personnel to receive real-time data associated with maintenance faults on the aircraft. When coupled with the FDAMS data, airline maintenance personnel could now start planning repair and maintenance activities while the aircraft was still in flight.Interactive Crew InterfaceAll of the processing described above is performed automatically by the ACARS MU and the associated other avionics systems, with no action performed by the flight crew. As part of the growth of the ACARS functionality, the ACARS MUs also interfaced directly with a control display unit (CDU), located in the cockpit. ThisCDU, often referred to as an MCDU or MIDU, provides the flight crew with the ability to send and receive messages similar to today’s email. To facilitate this communication, the airlines in partnership with their ACARS vendor, would define MCDU screens that could be presented to the flight crew and enable them to perform specific functions. This feature provided the flight crew flexibility in the types of information requested from the ground, and the types of reports sent to the ground.As an example, the flight crew could pull up an MCDU screen that allowed them to send to the ground a request for various weather information. Upon entering in the desired locations for the weather information and the type of weather information desired, the ACARS would then transmit the message to the ground. In response to this request message, ground computers would send the requested weather information back to the ACARS MU, which would be displayed and/or printed. Airlines began adding new messages to support new applications (Weather, Winds, Clearances, Connecting Flights, etc.) and ACARS systems became customized to support airline unique applications, and unique ground computer requirements. This results in each airline having their own unique ACARS application operating on their aircraft. Some airlines have more than 75 MCDU screens for their flight crews, where other airlines may have only a dozen different screens. In addition, since each airline’s ground computers were different, the contents and formats of t he messages sent by an ACARS MU were different for each airline.In the wake of the crash of Air France Flight 447, there has been discussion about making the ACARS into an "online-black-box."[2]If such a system were in place, it would avoid the loss of data due to: (1) black-box destruction, and (2) inability to locate the black-box following loss of the aircraft. However the cost of this, due to the high bandwidth requirements, would be excessive and there have been very few incidents where the black boxes were not recoverable.How it worksA person or a system on board may create a message and send it via ACARS to a system or user on the ground, and vice versa. Messages may be sent either automatically or manually.VHF subnetworkA network of VHF ground radio stations ensure that aircraft can communicate with ground end systems in real-time from practically anywhere in the world. VHF communication is line-of-sight, and provides communication with ground-based transceivers (often referred to as Remote Ground Stations or RGSs). The typical range is dependent on altitude, with a 200-mile transmission range common at high altitudes. Thus VHF communication is only applicable over landmasses which have a VHF ground network installed.A typical ACARS VHF transmission.Mode AAircraft B-18722Ack NAKBlock id 2Flight CI5118Label B9Msg No. L05AMessage /KLAX.TI2/024KLAXA91A1SATCOM and HF subnetworksSATCOM provides worldwide coverage, with the exception of operation at the high latitudes (such as needed for flights over the poles). HF datalink is a relatively new network whose installation began in 1995 and was completed in 2001. HF datalink is responsible for new polar routes. Aircraft with HF datalink can fly polarroutes and maintain communication with ground based systems (ATC centers and airline operation centers). ARINC is the only service provider for HF datalink.Datalink message typesACARS messages may be of three types:∙Air Traffic Control (ATC)∙Aeronautical Operational Control (AOC)∙Airline Administrative Control (AAC)ATC messages are used to communicate between the aircraft and Air traffic control. These messages are defined in ARINC Standard 623. ATC messages are used by aircraft crew to request clearances, and by ground controllers to provide those clearances.AOC and AAC messages are used to communicate between the aircraft and its base. These messages are either standardized according ARINC Standard 633 or defined by the users, but must then meet at least the guidelines of ARINC Standard 618. Various types of messages are possible, and these include fuel consumption, engine performance data, aircraft position, as well as free text data.Example of transmissions: Departure delay downlinkA pilot may want to inform his flight operations department that departure has been delayed by Air Traffic Control (ATC). The pilot would first bring up a CMU MCDU screen that allows him to enter the expected time of the delay and the reason for the delay. After entering the information on the MCDU, the pilot would then press a “SEND” key on the MCDU. The CMU would detect th e SEND key being pushed, and would then generate a digital message containing the delay information. This message may include such information as aircraft registration number, the origination and destination airport codes, the current ETA before the delay and the currentexpected delay time. The CMU would then send the message to one of the existing radios (HF, SATCOM or VHF, with the selection of the radio based on special logic contained within the CMU). For a message to be sent over the VHF network, the radio would transmit the VHF signals containing the delay message. This message is then received by a VHF Remote Ground Station (RGS).The majority of ACARS messages are typically only 100 to 200 characters in length. Such messages are made up of a one-block transmission from (or to) the aircraft. One ACARS block is constrained to be no more than 220 characters within the body of the message. For downlink messages which are longer than 220 characters, the ACARS unit will split the message into multiple blocks, transmitting each block to the RGS (there is a constraint that no message may be made up of more than 16 blocks). For these multi-block messages, the RGS collects each block until the complete message is received before processing and routing the message. The ACARS also contains protocols to support retry of failed messages or retransmission of messages when changing service providers.Once the RGS receives the complete message, the RGS forwards the message to the datalink service provider's (DSP) main computer system. The DSP ground network uses landlines to link the RGS to the DSP. The DSP uses information contained in their routing table to forward the message to the airlines or other destinations. This table is maintained by the DSP and identifies each aircraft (by tail number), and the types of messages that it can process. (Each airline must tell its service provider(s) what messages and message labels their ACARS systems will send, and for each message, where they want the service provider to route the message. The service provider then updates their routing tables from this information.) Each type of message sent by the CMU has a specific message label, which is contained in the header information of the message. Using the label contained in the message, the DSP looks up the message and forwards to the airline’s computer system. The message is then processed by the airline’s computer system.This processing performed by an airline may include reformatting the message, populating databases for later analysis, as well as forwarding the message to other departments, such as flight operations, maintenance, engineering, finance or other organizations within an airline. In the example of a delay message, the message may be routed via the airlin e’s network to both their operations department as well as to a facility at the aircraft’s destination notifying them of a potential late arrival.The transmission time from when the flight crew presses the send key to send the message, to the time tha t it is processed within an airline’s computer system varies, but is generally on the order of 6 to 15 seconds. The messages that are sent to the ground from the CMU are referred to as a downlink message.Example of uplink: Weather reportFor a message to be transmitted to the aircraft (referred to as an uplink message), the process is nearly a mirror image of how a downlink is sent from the aircraft. For example, in response to an ACARS downlink message requesting weather information, a weather report is constructed by the airline’s computer system. The message contains the aircraft registration number in the header of the message, with the body of the message containing the actual weather information. This message is sent to the DSP's main computer system.The DSP transmits the message over their ground network to a VHF remote ground station in the vicinity of the aircraft. The remote ground station broadcasts the message over the VHF. The on-board VHF radio receives the VHF signal and passes the message to the CMU (with the internal modem transforming the signal into a digital message). The CMU validates the aircraft registration number, and processes the message.The processing performed on the uplink message by the CMU depends on the specific airline requirements. In general, an uplink is either forwarded to another avionics computer, such as an FMS or FDAMS, or is processed by the CMU. Formessages (such as a weather report uplink) destined for the CMU, the flight crew can go to a specific MCDU screen which contains a list of all of the received uplink messages. The flight crew can then select the weather message, and have the message viewed on the MCDU. The ACARS unit may also print the message on the cockpit printer (either automatically upon receiving the message or upon flight crew pressing a PRINT prompt on the MCDU screen).Example of downlink: FDAMS messageMessages are sent to the ground from other on-board systems in a similar manner as the delay message example discussed previously. As an example, an FDAMS system may have a series of algorithms active to monitor engine exceedance conditions during flight (such as checking engine vibration or oil temperature exceeding normal operating conditions). The FDAMS system, upon detecting such an event, automatically creates an engine exceedance condition message, with applicable data contained within the body of the message. The message is forwarded to the CMU, using what is referred to as ARINC 619 data protocols. The CMU would then transmit the message to the ground. In this case, the service provider routing table for an engine exceedance message is typically defined to have the message routed directly to an airline’s maintenanc e department. This enables airline maintenance personnel to be notified of a potential problem, in real time.The components of ACARSThere are three major components to the ACARS datalink system:∙Aircraft equipment∙Service provider∙Ground processing systemAircraft equipmentThe heart of the datalink system on board the aircraft is the ACARS Management Unit (MU). The older version of MU is defined in ARINC Characteristic 724B. Newer versions are referred to as the Communications Management Unit (CMU) and are defined in ARINC Characteristic 758.Aircraft equipment consists of airborne end systems and a router. End systems are the source of ACARS downlinks and the destination for uplinks. The MU/CMU is the router. Its function is to route a downlink by means of the most efficient air-ground subnetwork. In many cases, the MU/CMU also acts as an end system for AOC messages.Typical airborne end systems are the Flight Management System (FMS), datalink printer, maintenance computer, and cabin terminal. Typical datalink functions are:∙FMS - sends flight plan change requests, position reports, etc. Receives clearances and controller instructions.∙Printer - as an end system, can be addressed from the ground to automatically print an uplink message.∙Maintenance Computer - downlinks diagnostic messages. In advanced systems, in-flight troubleshooting can be conducted by technicians on the ground by using datalink messages to command diagnostic routines in the maintenance computer and analyzing downlinked results.∙Cabin Terminal - Often used by flight attendants to communicate special needs of passengers, gate changes due to delays, catering, etc.ACARS messages are transmitted over one of three air-ground subnetworks.∙VHF is the most commonly used and least expensive. Transmission is line-of-sight so VHF is not available over the oceans.∙SATCOM provides worldwide coverage (except in polar regions) by means of the INMARSAT satellite network. It is a fairly expensive service.HF is the most recently established subnetwork. Its purpose is to provide coverage in the polar regions where SATCOM coverage is unreliable.The router function built into the MU/CMU determines which subnetwork to use when routing a message from the aircraft to the ground. The airline operator provides a routing table that the CMU uses to select the best subnetwork.Datalink Service ProviderThe role of the datalink service provider (DSP) is to deliver a message from the aircraft to the ground end system, and vice versa.Because the ACARS network is modeled after the point-to-point telex network, all messages come to a central processing location. The DSP routes the message to the appropriate end system using its network of land lines and ground stations. Before the days of computers, messages would come in to the central processing location and be punched to paper tape. The tape would be physically carried to the machine connected to the intended destination. Today the routing function is done by computer, but the model remains the same.There are currently two primary service providers of ground networks in the world (ARINC and SITA), although specific countries have implemented their own network, with the help of either ARINC or SITA. ARINC operates a worldwide network and has also assisted the CAAC in China, as well as Thailand and South America with the installation of VHF networks. SITA has operated the network in Europe, Middle East, South America and Asia for many years. They have also recently started a network in the US to compete with ARINC.Until recently, each area of the world was supported by a single service provider. This is changing, and both ARINC and SITA are competing and installing networks that cover the same regions.Ground End SystemThe ground end system is the destination for downlinks, and the source of uplinks. Generally, ground end systems are either government agencies such as CAA/FAA, an airline operations headquarters, or in the case of small airlines or general aviation consumers, a subscription based solution. CAA end systems provide air traffic services such as clearances. Airline and general aviation operations provide information necessary for operating the airline or flight department efficiently, such as gate assignments, maintenance, passenger needs, etc. In the early history of ACARS most airlines created their own host systems for managing their ACARS messages. Commercial off-the-shelf products are now widely available to manage the ground hosting.ARINC SpecificationsMuch of the processing performed by the CMU as well as basic requirements of the hardware are defined by ARINC specifications. The following is a list of the major ARINC specifications that define standards that govern many aspects of ACARS systems:ARINC documents and their specificationsARINC 607 Design Guidance for Avionics Equipment.

Also defines the format of the ACARS messages sent by the ACARS / CMU as well as received by the ACARS CMU. The format of this message is called a Type A message. Thischaracteristic has been updated to define the future VDL Mode 2 AOA operation.ARINC 619 Defines the protocols for the ACARS / CMU to use to transfer file data between other avionics in the aircraft. ARINC 619 covers file protocols that are used to interface with FMS, FDAMS, Cabin Terminal, Maintenance Computers, SATCOM systems and HF Voice Data Radios.ARINC 620 Defines ground-to-ground communication protocols. This includes the message format of messages routed between a service provider and an airline or other ground system. This is referred to as a Type B message (the air/ground Type A message is reformatted to a Type B message for ground transmissions).ARINC 622 Describes the processing associated with sending ATC application messages over today’s ACARS links (including ARINC 623 ATC messages).ARINC 623 This characteristic identifies ATC related messages that can be generated or received by an ACARS MU / CMU system (does not include FANS-1 or FANS-A messages that are processed by the FMS)ARINC 629 Specification for receiving and broadcasting ARINC 629 broadcast data (data transfer between avionics LRUs).

论文的英文翻译English Translation of a Thesis (700 words)Title: Impact of Climate Change on Biodiversity Conservation EffortsAbstract:Climate change is a global phenomenon that has significant implications for biodiversity conservation efforts worldwide. This paper aims to explore the impact of climate change on the existing strategies and approaches used in the conservation of biodiversity. Through a comprehensive review of relevant literature, this study provides insights into the potential consequences of climate change on species extinction rates, habitat loss, and ecological disruptions. Furthermore, it examines the challenges in conservation practices posed by climate change and proposes adaptive management strategies to mitigate its effects. The overarching goal of this research is to contribute to the development of effective and sustainable conservation approaches in the face of climate change.Introduction:Biodiversity plays a crucial role in maintaining the stability and resilience of ecosystems, providing vital ecosystem services that sustain human societies. However, climate change presents a major threat to biodiversity as it alters the ecological conditions upon which species depend. The accelerating rate of climate change has significant implications for the distribution and abundance of species, leading to shifts in species ranges and altering ecologicalinteractions. In order to preserve the earth's biodiversity, it is essential to understand the impact of climate change on existing conservation efforts and develop adaptive strategies to mitigate these effects.Climate Change and Species Extinction:Climate change is likely to increase species extinction rates as it disrupts ecological systems and impairs the ability of species to adapt to changing conditions. Changes in temperature and precipitation patterns can lead to shifts in the availability of resources, making it more challenging for species to find suitable habitats and maintain their populations. Furthermore, climate change can exacerbate existing stressors such as habitat degradation, pollution, and invasive species, making it even more difficult for vulnerable species to survive. This highlights the urgency of developing conservation strategies that consider the implications of climate change and prioritize the protection of vulnerable species.Habitat Loss and Fragmentation:Climate change contributes to habitat loss and fragmentation, which are key drivers of biodiversity decline. Rising temperatures can trigger the loss of habitats such as polar ice caps, coral reefs, and mangroves, leading to the displacement and extinction of numerous species. Additionally, changing rainfall patterns can alter the structure and function of ecosystems, affecting the availability of suitable habitats for different species. These changes in habitat composition and distribution can disrupt ecologicalinteractions and lead to cascading effects on biodiversity. Conservation efforts must recognize the dynamic nature of habitats and work towards preserving and restoring ecosystems to maintain biodiversity in the face of climate change.Adaptive Management Strategies:To effectively address the challenges posed by climate change, adaptive management strategies need to be implemented in conservation practices. This involves incorporating flexibility and resilience into conservation plans to account for future climate uncertainties. Adaptive management principles include monitoring and assessing the impacts of climate change on biodiversity, promoting genetic diversity and species migration, and engaging local communities in conservation efforts. Furthermore, integrating climate change data into conservation planning can inform the design of protected areas and corridors that allow for species movement and adaptation. Collaboration among scientists, policymakers, and local communities is crucial in developing and implementing these adaptive strategies.Conclusion:The impact of climate change on biodiversity conservation efforts is significant and requires urgent action. This study has highlighted the potential consequences of climate change on species extinction rates, habitat loss, and ecological disruptions. It emphasizes the need for adaptive management strategies that consider the dynamic nature of habitats and promote resilience in the face of climate uncertainties. Developing effective and sustainable conservationapproaches that integrate climate change considerations will be essential to safeguarding biodiversity in the future.。

Inventory managementInventory ControlOn the so-called "inventory control", many people will interpret it as a "storage management", which is actually a big distortion.The traditional narrow view, mainly for warehouse inventory control of materials for inventory, data processing, storage, distribution, etc., through the implementation of anti-corrosion, temperature and humidity control means, to make the custody of the physical inventory to maintain optimum purposes. This is just a form of inventory control, or can be defined as the physical inventory control. How, then, from a broad perspective to understand inventory control? Inventory control should be related to the company's financial and operational objectives, in particular operating cash flow by optimizing the entire demand and supply chain management processes (DSCM), a reasonable set of ERP control strategy, and supported by appropriate information processing tools, tools to achieved in ensuring the timely delivery of the premise, as far as possible to reduce inventory levels, reducing inventory and obsolescence, the risk of devaluation. In this sense, the physical inventory control to achieve financial goals is just a means to control the entire inventory or just a necessary part; from the perspective of organizational functions, physical inventory control, warehouse management is mainly the responsibility of The broad inventory control is the demand and supply chain management, and the whole company's responsibility.Why until now many people's understanding of inventory control, limited physical inventory control? The following two reasons can not be ignored:First, our enterprises do not attach importance to inventory control. Especially those who benefit relatively good business, as long as there is money on the few people to consider the problem of inventory turnover. Inventory control is simply interpreted as warehouse management, unless the time to spend money, it may have been to see the inventory problem, and see the results are often very simple procurement to buy more, or did not do warehouse departments .Second, ERP misleading. Invoicing software is simple audacity to call it ERP, companies on their so-called ERP can reduce the number of inventory, inventory control, seems to rely on their small software can get. Even as SAP, BAAN ERP world, the field ofthese big boys, but also their simple modules inside the warehouse management functionality is defined as "inventory management" or "inventory control." This makes the already not quite understand what our inventory control, but not sure what is inventory control.In fact, from the perspective of broadly understood, inventory control, shouldinclude the following:First, the fundamental purpose of inventory control. We know that the so-called world-class manufacturing, two key assessment indicators (KPI) is, customer satisfaction and inventory turns, inventory turns and this is actually the fundamental objective of inventory control.Second, inventory control means. Increase inventory turns, relying solely on the so-called physical inventory control is not enough, it should be the demand and supply chain management process flow of this large output, and this big warehouse management processes in addition to including this link, the more important The section also includes: forecasting and order processing, production planning and control, materials planning and purchasing control, inventory planning and forecasting in itself, as well as finished products, raw materials, distribution and delivery of the strategy, and even customs management processes.And with the demand and supply chain management processes throughout the process, it is the information flow and capital flow management. In other words, inventory itself is across the entire demand and supply management processes in all aspects of inventory control in order to achieve the fundamental purpose, it must control all aspects of inventory, rather than just manage the physical inventory at hand.Third, inventory control, organizational structure and assessment.Since inventory control is the demand and supply chain management processes, output, inventory control to achieve the fundamental purpose of this process must be compatible with a rational organizational structure. Until now, we can see that many companies have only one purchasing department, purchasing department following pipe warehouse. This is far short of inventory control requirements. From the demand and supply chain management process analysis, we know that purchasing and warehouse management is the executive arm of the typical, and inventory control should focus on prevention, the executive branch is very difficult to "prevent inventory" for the simple reason that they assessment indicatorsin large part to ensure supply (production, customer). How the actual situation, a reasonable demand and supply chain management processes, and thus set the corresponding rational organizational structure and is a question many of our enterprisesto exploreThe role of inventory controlInventory management is an important part of business management. In the production and operation activities, inventory management must ensure that both the production plant for raw materials, spare parts demand, but also directly affect the purchasing, sales of share, sales activities. To make an inventory of corporate liquidity, accelerate cash flow, the security of supply under the premise of minimizing Yaku funds, directly affects the operational efficiency. Ensure the production and operation needs of the premise, so keep inventories at a reasonable level; dynamic inventory control, timely, appropriate proposed order to avoid over storage or out of stock; reduce inventory footprint, lower total cost of inventory; control stock funds used to accelerate cash flow.Problems arising from excessive inventory: increased warehouse space andinventory storage costs, thereby increasing product costs; take a lot of liquidity, resultingin sluggish capital, not only increased the burden of payment of interest, etc., would affect the time value of money and opportunity income; finished products and raw materials caused by physical loss and intangible losses; a large number of enterprise resource idle, affecting their rational allocation and optimization; cover the production, operation of the whole process of the various contradictions and problems, is not conducive to improve the management level.Inventory is too small the resulting problems: service levels caused a decline in the profit impact of marketing and corporate reputation; production system caused by inadequate supply of raw materials or other materials, affecting the normal production process; to shorten lead times, increase the number of orders, so order (production) costs; affect the balance of production and assembly of complete sets.NotesInventory management should particularly consider the following two questions:First, according to sales plans, according to the planned production of the goods circulated in the market, we should consider where, how much storage.Second, starting from the level of service and economic benefits to determine howto ensure inventories and supplementary questions.The two problems with the inventory in the logistics process functions.In general, the inventory function:(1)to prevent interrupted. Received orders to shorten the delivery of goods fromthe time in order to ensure quality service, at the same time to prevent out of stock.(2)to ensure proper inventory levels, saving inventory costs.(3)to reduce logistics costs. Supplement with the appropriate time interval compatible with the reasonable demand of the cargo in order to reduce logistics costs, eliminate or avoid sales fluctuations.(4)ensure the production planning, smooth to eliminate or avoid sales fluctuations.(5)display function.(6)reserve. Mass storage when the price falls, reduce losses, to respond to disasters and other contingencies.About the warehouse (inventory) on what the question, we must consider the number and location. If the distribution center, it should be possible according to customer needs, set at an appropriate place; if it is stored in central places to minimize the complementary principle to the distribution centers, there is no place certain requirements. When the stock base is established, will have to take into account are stored in various locations in what commodities.库存管理库存控制在谈到所谓“库存控制”的时候，很多人将其理解为“仓储管理”，这实际上是个很大的曲解。
