新分析方法建立的一般过程1

新分析方法建立的一般过程由于工业分析对象广泛,分析项目和测定要求是多种多样的,因此分析方法也是多种多样的。
[1]色谱法是近代分析化学中发展最快、应用最广的分离分析技术,在化学、生物学等领域发挥着越来越重要的作用,并正发展成为一门新兴学科。
现代色谱分析将分离和连续测定结合,也可以浓缩、分离、测定联用,对复杂体系中组分、价态、化学性质相近的元素和化合物进行分析。
色谱分析仍是残留分析技术发展的主流。
下面以色谱分析法为例说明残留分析方法建立的基本步骤。
1 文献检索文献检索通常仅能显示最适宜的分析方法,并提供样品处理、分离和检测方面的粗略信息。
通过查阅文献可以对以往分析方法进行比较和借鉴,了解与方法设计相关的背景资料。
这些工作对于研究者根据具体的试验条件调整、改进或新建立符合要求的分析方法都十分重要。
设计全新的分析方法时,如针对新对象或采用新技术,可以从较早发表的化学合成文献得到待测物理化性质或分离方面的原始资料,或从具有相近结构或官能团化合物的分析方法中获得某些信息或启示。
2 建立测定方法首先建立测定方法和线性范围,为各种后续工作提供分析手段,最后根据干扰和使用情况逐步确立测定条件和建立标准曲线。
3 建立样品处理方法一般采用纯水作为样品基质进行预试,目的是了解液-液萃取(LLE)或固相萃取(SPE)条件、试剂干扰和回收率情况,然后再依次用空白样品和标准品添加样品进行研究。
4 标准曲线测定条件确定后,即可配制系列浓度的标准液制备标准曲线。
至少设4个浓度,每个浓度水平设3次重复。
制备标准曲线的浓度须涵盖样品可能的浓度范围,不进行外推计算。
可以采用外标法或内标法定量。
残留样品浓度波动范围和测定误差较大,宜采用标准曲线或回归方程计算含量。
在使用过程中需每日对标准曲线进行校正。
5 稳定性试验一般包括标准溶液和样品在贮存条件下的稳定性试验,如室温、冷冻和反复冷冻—解冻条件下的稳定性。
6 分析方法评价为保证分析结果的质量,任何一种分析方法根据分析对象和要求都必须满足一定的效能指标,如准确度、精密度、灵敏度等。
系统分析方法的步骤

系统分析方法的步骤系统分析方法的具体步骤包括:限定问题、确定目标、调查研究收集数据、提出备选方案和评价标准、备选方案评估和提出最可行方案。
1、限定问题所谓问题,是现实情况与计划目标或理想状态之间的差距。
系统分析的核心内容有两个:其一是进行“诊断”,即找出问题是及其原因;其二是“开处方”,即提出解决问题的最可行方案。
所谓限定问题,就是要明确问题的本质或特性、问题存在范围和影响程度、问题产生的时间和环境、问题的症状和原因等。
限定问题是系统分析中关键的一步,因为如果“诊断”出错,以后开的“处方”就不可能对症下药。
在限定问题时,要注意区别症状和问题,探讨问题原因不能先入为主,同时要判别哪些是局部问题,哪些是整体问题,问题的最后确定应该在调查研究之后。
2、确定目标系统分析目标应该根据客户的要求和对需要解决问题的理解加以确定,如有可能应尽量通过指标表示,以便进行定量分析。
对不能定量描述的目标也应该尽量用文字说明清楚,以便进行定性分析和评价系统分析的成效。
3、调查研究,收集数据调查研究和收集数据应该围绕问题起因进行,一方面要验证有限定问题阶段形成的假设,另一方面要探讨产生问题的根本原因,为下一步提出解决问题的备选方案做准备。
调查研究常用的有四种方式,即阅读文件资料、访谈、观察和调查。
收集的数据和信息包括事实(facts)、见解(opinions)和态度(attitudes)。
要对数据和信息去伪存真,交叉核实,保证真实性和准确性。
4、提出备选方案和评价标准通过深入调查研究,使真正有待解决的问题得以最终确定,使产生问题的主要原因得到明确,在此基础上就可以有针对性地提出解决问题的备选方案。
备选方案是解决问题和达到咨询目标可供选择的建议或设计,应提出两种以上的备选方案,以便提供进一步评估和筛选。
为了对备选方案进行评估,要根据问题的性质和客户具备的条件。
提出约束条件或评价标准,供下一步应用。
5、备选方案评估根据上述约束条件或评价标准,对解决问题备选方案进行评估,评估应该是综合性的,不仅要考虑技术因素,也要考虑社会经济等因素,评估小姐应该有一定代表性,除咨询项目组成员外,也要吸收客户组织的代表参加。

關鍵字:層級分析法、多準則決策理論、3-Step AHPKNOWLEDGE–BASE PROJECT SELECTION USING3-Step AHPChin-Chia Yen Yi-Hsuan ChenDepartment of Business AdministrationKai Nan UniversityABSTRACT:The faster the environment changes, the higher value of the adaptation for enterprises. Variation is part of the management for the specialized project; on the other hand, the combination management in the professional project is regarded as the working flow chart of the enterprise in the 21th centuries. Knowledge investigation not only increases the value of knowledge, but also changes the way of working; furthermore, it is identical with the strategic goal of the enterprise. Knowledge enterprise must know how to choose, design and manage the knowledge project. The research mainly applies multi-principle policy to how to choose on the knowledge project for the knowledge industry.This paper is concerned with development of multi-attribute evaluation model for Knowledge Base of Project Selection Major technologies used for this study are; AHP(analysis hierarchy process), In this study, we developed a 3-step approach, three step model are: 1. brainstorming module for idea and alternative generation, 2. AHP(analysis hierarchy process) for evaluation of alternative, and 3.priority integration module to aggregate the multiple rank-ordered sets based on priority. However the proposed model can provide Knowledge Base of Project decision makers to get the best alternative.KEYWORDS: AHP, Knowledge Management, Project Management一、INTRODUCTIONThe coming new society is a knowledge society. Not only knowledge will become the main resource, but also the knowledge workers become the main labor. The means knowledge workers need to make good use of their tools and combine with some organization. The organization collect knowledge worker and transfer their specialized knowledge on the final product.Except for the non-preservation of the knowledge itself, knowledge will decline with the time going. This way, knowledge management works through the cycle process which refers to systematized creation, getting, integration, accumulation, share and renewal to meet thecontinuously development.In other words, knowledge management system is the continuously management process which not only make the preservation of experience, knowledge, and specialization of the organization, but also improve the learning capability. Furthermore, it can create the new value in the intangible asset, then increase the performance and reinforce the customer value. In order to optimize the knowledge management and consider the time, cost and quality, the organization will use the AHP to help the decision maker to analyze any problem. The system which is a basis of decision making is helpful for the decision maker to systematize the complicated problem and choose the priorities of any alternatives.AHP was invented by Thomas Satty in 1970s, with the development for 30 years, AHP has become matured and widely used tool.The purpose of this study is to develop a decision support system in the view of multi-attribute structured system. Most of the conventional concepts used in decision support system do not seem to be appropriate for modeling the kind of the multi-attribute characteristics.A great deal of researches have been under taken on decision support system to determine the proper alternatives. For example, operations research, mathematical models and decision theory (Kamarani, 1995; Fishburn, 1971 ), while there are few researches to develop solution builders for these decision support systems based on multi-attributes analysis.Entering the 21 centuries which is the knowledge economy times, the most important asset is human and organization knowledge. How to train the employees by effective knowledge management and increase the value of the organization has become an important issue for the enterprises in the knowledge economy times. The industry which is highly knowledge concentrated need to combine knowledge product, service and project; this way, the lesson learning of project management can be transferred to be the useful knowledge and create knowledge product or service by the principle of the project management. Consequently, the knowledge project can have the leverage effect and maximize the profit, and then the decision maker can manage the project knowledge by knowledge management to increase the successful rate of the project. Manage the following Figure 1 of the relation with information management in special project.The professors established the model to discuss and elect the multi-project in order to systematize and rationalize the problem regarding the election of the knowledge project. The framework of knowledge management using computer network Select the most applicable components from project management perspective. Internal databases should be conducted security control to establish the appropriate network for knowledge management.Figure 1. Interaction model of KM and PM二、THREE-STEP APPROACH OF ENGINEERING PROJECTEV ALUATIONWe develop a systematic and practical computer program to solve the three-step approach of knowledge base of project evaluation problem. Computational experiments are performed to a set of sample problem and show the effectiveness of the proposed model. In the first step, to create the ideas to drive out alternatives from a group analysis, we used the brainstorming method , and in step 2, we used the AHP(Murphy, 1995) method on evaluate the decision alternation derived out in the step 1 and determined the preferred alternative. In the last step, we show the integrate the results of individual evaluation into one ranked order. We develop two heuristic methods based on majority rule method. Figure 2 shows the schematic structure of three-step approach of proposed project evaluation and shows the main program of proposed approach.Figure 2. Three-step approach of project evaluation system三、CASE STUDYThe research takes some example to approve the opinion. We establish a decision model in the knowledge project by the method of AHP and elect the best policy for the company. In the process of electing, the members of the company all bring up their ideas by brainstorming. The principle of election includes information getting, R&D, the improvement of productivity, the improvement of creation and research on the producing process and feasibility; in addition, these are alternatives1.Data Base Server: The Data Base Server may store up each kind of related importantinformation, but if not after the detailed plan and the design, the ornamental hairpin material is unable to display its use, only has the process to classify processing and the make the best of, the manager and the colleague can obtain from these materials significant the information, then uses these information to assist some decision-making.2.e-Bulletin: e-Bulletin board is provides the person which has the interest to some businessto be allowed mutually to circulate the study the place. And lets in the enterprise, the outside user immediate gain first enterprise, the service and the product news, is the knowledge management best manages the tool. The two mechani sms, organizations’ offer and employees’ search, and the appliances, e-Bulletin disseminated knowledge from organizations to individuals.3.Intranet: The Intranet is unifies the enterprise computer and the network, its member maythe segment share computer resources and the exchange information. With group of networks agreements and common tool, in order to with achieves the cross platform connection to the use different soft hardware. Intranet is uses Internet the communication technology to establish, when to establishes Intranet, only on the existing hardware equipment makes the expansion, certainly does not need extra payment.4. Knowledge Group : The Knowledge Group contribution lies in the enhancementorganization the value, the enterprise does not arrest is restricted in traditional the organization level, but established to have the elastic organizational structure. Constructs the construction knowledge group the way, is has each classified knowledge the person which the specialty or has the demand to condense in together, the use science and technology, establishes the communication.3-1 Knowledge-based Brainstorming to Define the Evaluation Factors and Alternatives (Step 1)The alternative of evaluation and its evaluation method can be determined based on the system attributes and experiences of evaluators. To construct the decision structures and alternatives, include the group decision ideas, and we used a brainstorming method to create the ideas of alternatives for decision support system analysis of various groups. We use the brainstorming method in the knowledge-based environment. Figure 3 shows multi-echelon structure of the project evaluation where T, Y and X mean the evaluation factors of each decision level. We constructed the evaluation structure by brainstorming process. Figure 4 shows a sample output of alternative generation and the decision structure of a sample with 3-echelon structure and 4 alternatives by brainstorming.Figure 3. Multi-attribute Structure of Project EvaluationEvaluation Project Alternative Using AHP (Step 2)For the performance evaluation of decision alternatives, we used a multi-echelon andX 1 X 3 X 4 X 5 X 6 X 7 X 8 X 9 X 2multi-attribute analysis method as those of AHP set priority method (Zahedi 1986). It is performed by following four steps : 1, construct a hierarchical structure. 2, pair-wise matrix of decision factors. 3, compute the weighted value. And 4, consistency analysis. The solution builder consisted of main menu, tool bar, node editor, canvas and status as in Figure 5. For each level of structure we find the eigen-value by pair-wise comparison matrix based on Saaty’s (1981) 9 point grading. Table 1 shows a sample output pair-wise matrix of sample problem. To construct the hierarchical structure of project evaluation we define the performance factors and generate alternatives by the brainstorming and AHP. Figure 5 shows the sample outputs of hierarchical structure AHP and project evaluation structure constructed by brainstorming process.Figure 4. The knowledge type special project group of Hi-Tech company using brainstorming, propose 4 alternative projects:「Date Base Server」、「e-Bulletin」、「Intranet.」、「Knowledge Group」Figure 5. Sample Output of Project Evaluation Structure Using BrainstormingFigure 6. Pair-wise Comparison MatrixThe sample of pair-wise comparison matrix are given in Figure 6 and sample result of pair-wise matrix by each level are shows in Table 1:Table 1. The sample outputs of pair-wise matrix0)level I1)level IIIntegration Of Individual Evaluation (Step 3)For the integration of the results of individual evaluations, prioritized sets, we developed Method 1 set priority method which are kind of majority-rule methods. We compared the results of these methods to determine the most preferred one for the purpose of knowledge base project evaluation system.1.Method 1:In this method the preference score is given by the sum of the marks received from the evaluators, where for m alternatives, the marks are given, in decreasing order preference, (m-1), (m-2),….., 0. The ranking was based on the scores of each alternative. In this case, the highest score will be the first priority. For example of the Heuristic Method 1, a sample result with N=3 evaluators and M=4 alternative is given by:Evaluator 1:C>D>A>B>D>AEvaluator 2:C>BEvaluator 3:D>A>We get the result by using the method of AHP. In the election of the knowledge project, intranet is the most important and the following is establishment of knowledge group. This way, in the process of finding the knowledge project, we should set up the intranet first of all and encourage to build up the knowledge group. In addition, we should develop the enterprise culture which tends to learn and share knowledge to improve the effect of knowledge project and competitiveness of the enterprise.3-2 Implementation of the proposed ModelWe implied this model to a set of example of multi-structured knowledge base project evaluation system as shown in Figure 2. First, we determined the project evaluation factors and alternative using brainstorming and construct the decision structure as shown in Figure 4, 5 and 6. Then, we found the weighted values of each project alternative by eigenvectors using AHP method as shown 6, Table 1.四、SUMMARY AND CONCLUSIONSWe developed a three-step approach for Knowledge-base project evaluation for multi-structured systems in the view of multi-attribute evaluation. In this study, we developed multi-attribute decision support system so as to work at remote station without attending evaluation meeting. Also, the proposed model includes the methods for constructing the decision alternative and evaluation factors using brainstorming, and used AHP. Finally, we developed the integrating method to integrate the individual evaluation results. For the illustration purpose, we implemented proposed model to sample examples and compared the sample results. Finally, for a simple and efficient computation, we have developed a systematic and practical program to calculate all the algorithms. The model was validated by comparative computations for various multi-structured project evaluation examples. By the sample results of AHP method, it is known that the proposed model is a good method for the performance evaluation of multi-attribute and multiple goals.The professors established the model to discuss and elect the multi-project in order to systematize and rationalize the problem regarding the election of the knowledge project. The result of the model for decision making are expected to provide the decision maker to choose the best policy according different needs and available resources.According to these results, maybe this enterprise should integrate task- related information system on the same platform to enhance degrees of task-technology-fit. Furthermore, employees generally thought every system in intranet were very important, the most big gaps between usage frequency and importance were on-line learning system and electrical meeting systems. It will behelpful to recommend this company to put the forth efforts on on-line learning systems, using the infrastructures on hand to providing job or task related programs, and matching up with certificate system to reinforcing digital learning functions to achieving the goals of employees levels.While proceeding the election of multi-project, the decision maker can also use the Method of Fuzzy AHP or use the QFD to reinforce the brainstorming according the situation. If the manager can examine the result by BSC or use SD to project the result, he can make the quick response and meet the need of the enterprise.五、REFERENCE(1) Barbarosoglu, G & Yazgas, T.

1.分析实验室除了搞好实验室的管理,还应重视科研, 通过科研提高科技人员的素质和能力。 2.一般实验室查阅外文资料的条件差,作为分析人员来 说,要有很强的查阅、翻译外文资料的意识,即设 法多看外文资料,这是提高自己和研能力的必要条 件。每人每年至少全文翻译2篇国外分析化学文献。 至于国内杂志,至少要经常看《理化检验-化学分册》 杂志。 3.与有经验的分析化学工作者多建立联系,尤其必须知 道自己工作领域中谁是有真才实学的专家。 4.现在实验室普通存在的问题:阅读外文文献的条件差、 没有真才实学的专家带你,参加学术会议的收获比 预想的低,国内学术刊物质量偏低(学术水平和可 靠性)有待提高。
第五步:撰写论文-分析研究报告
一、撰写论文原则 1.在“前言”部分客观介绍同行的研究工作。如果自己的研究工作 与国外同行有相似或相同之处,决不可故意不提同行的研究。 “前言”部分的撰写可准确反应作者的学术水平。 2.所介绍的实验条件准确、规范。在“分析手续”中应完整介绍整 个分析操作步骤,使他人可按照你的论文可重复你的实验(包括 可以准确地分析样品)。 现在有的论文,由于介绍的实验条件不完整,造成别人重复你的 方法时无法得到准确分析结果。 3.论文内的数据准确可靠 4.“结论”客观、准确、可信。 5.参考文献书写规范。参考文献中外文文献占的比例及数量是该论 文学术水平的重要标志。
第四步:关键性实验
CL-TBP萃淋树脂分离-ICPAES法测定高纯氧化铁中微量铅、砷、镍 和钴的关键性实验有: 一、离子交换树脂用量及树脂柱设计; 二、铅、砷、镍和钴在CL-TBP树脂上于HCl和HNO3分配系数Kd的测定; 三、CL-TBP萃淋树脂吸附容量的测定; 四、铅、砷、镍和钴在萃淋树脂上的淋洗曲线; 五、分离效果的检查,有时可用放射性示踪法,一般可用ICP-AES法, 分离效果的检查是检查分离的可靠性; 六、样品分析及加入回收试验,尽可能多做各种不同类型样品,以 发现样品分析时产生的问题,从而提高分析方法的适用性。 七、标准样品的分析。 标准样品的分析尤为重要,是考验分析方法可靠性最重要的方法。 八、关键性实验应重复地做,以便保证要解决的分析课题,这样的课题会获得 领导的支持。 2.本实验室仪器条件能胜任方法对仪器的要求。 3.一般的实验室刚开始搞分析方法研究可选择难度低的课题, 即有100%把握完成的课题; 水平较高的实验室可选择难题较高(学术水平较高)的课题。 4.不要过分强调自己的专长,例如,若本单位需要,就应该去 研究,不论是色谱还是光谱。 5.科研要有团队精神,不要单干,要齐心协力。
6.写分析化学论文方法 刚开始撰写论文,可参阅“理化检验-化学分册”杂志, 后 可参阅“分析化学”杂志,最好参阅国外分析化学杂志。 重点是:1.前言;2.关键实验;3.参考文献. 二、撰写论文目的 1.作为研究工作的总结; 2.准备发表(分析化学工作者应有较强的发表论文的意识 这对你很重要) 。希望国内外同行能看到你的研究工 作,这可提高你的知名度。希望你的论文在读者中留下 深刻印象(这是你要追求的)。 3.向哪个杂志发表,主要是考虑自己论文的学术水平: 一般实用性论文——“理化检验-化学分册”或相似杂志; 有一定深度或创新性论文——“分析化学” 有突出的原创性、学术价值确实比较大——国外分析化 学类杂志。 4.论文应至少在“核心期刊”上发表,采取被SCI收录或 “重要期刊”上发表,最好在国外分析化学类杂志发表。
