Supplies Strategy Study Of Manufacturing Enterprises Based On JIT

In JIT environment, Supplies become the bottleneck of enterprise survival and development. Establishment and implementation of an efficient and punctual JIT material supply model will enhance the competitiveness of manufacturing enterprises largely.Firstly, On the basis of the study of procurement management, inventory management and supplier relationship management three aspects under JIT environment, enterprises should use multi-frequency, low-volume JIT procurement and sustainable checking inventory control strategy that named(s, S) strategy in the implementation of JIT Supplies based on the actual production conditions. At the same time, to establish strategic partnerships with suppliers. Secondly, according to the material specific properties, the paper constructs a material classification model considering objective factors. And using AHP-DEA evaluation model to achieve comprehensive evaluation of material impact on profit Purchasing and procurement risks. The reasonable classification and localization of materials and analysis on characteristics of the four types of materials in material classification model, proposed targeted supplies strategy combined with the basic characteristics of JIT material supply. And accurately distinguish material that suitable JIT supply. Then proposed JIT material supply costs from the purchasing costs, holding costs and shortage cost components and identify the presence of specific factors as well as between the various factors of contact, thus identified four key factors: JIT material supply, safety inventory, inventory check interval, suppliers and maximum inventory levels, obtained by the simulation so that the best combination of lowest cost. Finally, the paper studies the ten materials of a car odometer of X company, conducted case study.
