In today's fierce market environment, competition among enterprises has evolved between the supply chain, competition, improve supply chain management is an important way to enhance competitiveness. Ideal supplier for the whole supply chain can bring huge benefits, the supplier will directly affect the merits of growth and development of the supply chain. Evaluation and selection of suppliers has become a smooth supply chain relationships, the basis for normal operation, the evaluation is the core provider and core business development to establish consistent evaluation system, while using a reasonable method of model. Index system is not a complete evaluation and selection can not work; no scientific methods of evaluation, there is no way of objective assessment of suppliers, reflecting the merits of the supplier.
From the relationship between domestic and foreign suppliers and the evaluation of the status and problems to start, based on supplier evaluation and selection of relevant theories of the Yang coal Hengtong Chemical Co., Ltd. Shandong, the two raw materials, calcium carbide and salt supplier evaluation system, in order to companies to better evaluate and select suppliers of calcium carbide and salt to provide a theoretical support and practical information.
This comprehensive research and have to follow certain ideas and principles based on the combination Hengtong Chemical Co., Ltd. Shandong, Shenyang Coal characteristics and calcium carbide and external environment, characteristics of salt suppliers, calcium carbide and salt were established supplier evaluation and selection of indicators system. Calcium carbide supplier evaluation and selection index system: capacity, price, quality, timely delivery rate, market share, long-term willingness to cooperate, sharing of information will, salt supplier evaluation and selection index system: price, quality, timely delivery rate, long-term cooperation and information sharing will wish; subsequent AHP to determine the weight of each index, and comprehensive evaluation model constructed with the salt of the calcium carbide composite score for the supplier provide the basis for ranking the merits; Finally, from the procurement process optimization, supplier evaluation process control, business management of the three aspects of the procurement process of the enterprise supplier evaluation and selection of protection measures for enterprises to better address the problem of supplier evaluation and selection to provide daily management of security.

This article from abroad supplier relations and the evaluation of the status quo and problems, based on supplier evaluation and selection of the related theory, studies the shandong YangMei hengtong chemical Co., LTD. Two major raw material supplier evaluation system with calcium carbide we, in order to enterprises better evaluation and selection of calcium carbide and we supplier provide certain theoretical support and reference reality.
Based on the synthesis of the existing research results and follow the certain ideas and principles in the foundation, the union of shandong YangMei hengtong chemical Co., LTD. Internal and external environment characteristics and calcium carbide, we established supplier characteristics, respectively with calcium carbide we supplier evaluation and selection index system. Calcium carbide supplier evaluation and selection index system for capacity, price, quality and timely supply rate, market share, cooperative intentions, information sharing will, we supplier evaluation and selection index system for: price, quality and timely supply rate, cooperative intentions and information sharing the will, Then USES ahp to each index weight, but also to build comprehensive evaluation model calculation of calcium carbide and composite scores for supplier, we provide a basis for the superiority of sorting, Finally from purchasing process optimization, supplier evaluation process control, enterprise procurement process management three aspects put forward enterprise supplier evaluation and selection of guaranteeing measures, for enterprises to better solve supplier evaluation and selection provide daily management guarantee.
