Research On Evaluation Of Equipment Procurement In Chemical Industry Project Based On Gray Theory

With China's sustained rapid development in recent years, the chemical industry projects are launched continuously. Chemical industry project playes a significant role in local economic development, at same time, as a strong environmental construction projects, it is concerned by the government, experts, local residents and other social parties, people put forward higher requirements on the quality of the projects. As a major important part of chemical industry construction projects, equipment procurement of chemical industry project plays a vital role in the success of project, it directly affects the quality safety, time, cost and other aspects of chemical industry projects. It is also one of the key issues which needs to researched in chemical industry construction projects.In view of the above, this paper studies the large chemical industry project equipment procurement management.In this paper, we analyze the characteristics of the procurement in large chemical industry project and impact factors in the evaluation of equipment procurement, establish evaluation index system of equipment procurement; then the evaluation method of equipment procurement based on grey theory is proposed in procurement chemical industry projects. this paper mainly studies two aspects of equipment evaluation.Firstly, we approach project purchasing situation both at home and overseas, as well as the characteristics of the procurement in large chemical industry project and theory of evaluation.Secondly, the index system of equipment evaluation is established for chemical industry project procurement. The index system of evaluation for equipment procurement mainly focuses on the following three aspects: strength of suppliers, technical performance of equipment (Such as environmental protection and security), and management indicators of time- quality-cost- risk in the process of equipment procurement.Thirdly, the evaluation mothed based on the grey theory is proposed for equipment procurement in chemical industry project. In the first place,the evaluation index weights is calculated by AHP and group decision making method, then the qualitative indicators are evaluated with whitening function of grey theory ;the quantitative indicators are evaluated with correlation analysis of grey theory, the integrated evaluation value is composed by evaluation results of quantitative indicators and qualitative indicators, then equipment suppliers of project procurement is selected .it solves the management and conformity in equipment procurement for large chemical project.Finally, the content of the study be used in practice in a large chemical project, the project's application shows he feasibility and effectiveness of the results of this study.
