Research On Supply Strategy Of Raw Material And Subsidiary Material For SY Chlor-alkali Company

SY chlor-alkali company is a medium-sized domestic chemical enterprise, at presentthe company in the supply management of raw material and subsidiary material inventoryclassification is not clear, inventory control strategy for single, safety inventory problems,which need to be improved.The research object of this thesis is SY chlor-alkalicompany.From the perspective of reducing the total cost of inventory, the author gives theraw material and subsidiary material inventory classification for SY chlor-alkalicompany,and gives different inventory control strategies for different types of materials.The concrete research contents include:Firstly, this paper sorts out inventory management theories, and analyzes thepurchasing characteristics、the inventory characteristics and problems of raw material andsubsidiary material of SY chlor-alkali company.Secondly, for the characteristics of existence for the raw material and subsidiarymaterial stocks of SY chlor-alkali company, This paper uses consumption， pricefluctuations and the amount of funds used factors, based on improved ABC inventoryclassification method by using fuzzy clustering analysis,and then classifies the raw materialand subsidiary material of SY chlor-alkali company into class A、class B and class C.Thirdly, based in prediction of raw material and subsidiary material demand, to reducethe total cost of the inventory, this paper gives the mathematical model for class A based onthe price fluctuations; the mathematical model for class B based on price and inventorycosts; and the mathematical model for class C based on (T,s,Q).Finally, through the calculation of calcium carbide、raw salt、sulfuric acid, the authordescribes the application effect of SY chlor-alkali company by using the inventory controlmodel.
