7.Calculate equipment quantities 8. Calculate staffing levels
9.Prepare possible building and site layouts
Define system requirements and design constrains
Finally, the aim of a design should always be to get the right design and technology to meet the given requirements.
Notes
1. The design of a warehouse and handling system involves a number of stages , starting with the definition of system requirements and constraints, and finishing with an evaluated preferred design. Although set out sequentially below, the design process is developed, and assessing the interactions that necessarily occur throughout the process. Any design process uses a range of skills and disciplines.
The design requirements for a warehouse or distribution depot operation, taking account of future growth forecasts and other likely business developments are likely to include: Required capacities, both storage and throughput; Service level to be achieved; Relevant constraints can include；
Postulate basic operations and methods
The basic operations that will take place in a warehouse , and how they will be carried out, must be determined before it is possible to specify the equipment , space or staffing levels required for them.

External Layouts
Identify the preferred design
External Layouts
The relevant factors that affect the site layout include: vehicle access to the site;
The layout brings together all the components of the warehouse operation inside the building, and also the external site features.
the general principles for internal layout include;
access for fire appliances;

Identify the preferred design
As a design progresses , there will inevitably be a process of iteration , of checking back to the design requirements, and partial evaluation of ideas to assist the process of homing in on the final preferred design.
security including harriers, gatehouses and separate access for cars and commercial vehicles;
internal roads and directions of movement, oneway or two-way circuits; car parking;
Analyze data
Data may be analyzed and presented in various ways, including graphs and charts , table , drawings , statistical analyses , drawings and networks.

good access to stock; Minimizing the amount of movement required for people and for handling equipment;
making the best use of building volume;
safe systems of work.
Calculate equipment quantities
The amount of equipment required is calculated from the basic design data and equipment operational characteristics.
Using stock and through figures, and equipment operating characteristics, the calculations of basic equipment are generally straightforward.
Time limit;
Financial limit; Technical limit；
Define and obtain data
The accuracy and completeness of the data on which any designed is based will affect how well the final design meets the specified requirements.
Define and obtain data
However, there are often gaps in the available data , and on occasions assumptions have to be made based on informed opinion and experience, and they should be clearly highlighted and justified in the final design document.

Consider possible equipment tapes for Storage and handling
It should be able to specify the appropriate equipment for a particular application clearly requires an awareness of what is available and an understanding of the basic operating characteristics of the different equipment types.
Establish what unit loads will be used
Examples of unit loads Include pallets stillage , roll cage pallets, skid sheets, tote boxes and hanging garment rails.
Quite clearly, staffing levels have to be established as part of the design, and to enable a full costing of the warehouse to be made.
