The Theory And Applicasion Of Fuzzy Inventory Basde On Structured Element

In this paperfuzzy numbers arithmetic expressed by structured element,conclued a structured element solution involding specific fuzzy parameters (storage costs, shortage costs,ordering costs,order price) of the fuzzy t -circle inventory model problem,greatly simplifying the calculation,avoiding the usual inverse fuzzy process.For the demand is fuzzy number,fuzzy-valued functions,as well as containing the fuzzy inventory price mechanism set up the corresponding inventory model.Use the fuzzy gravity decision-making and structured element weighted ranking to reverse the fuzzy processing,conclued the order quantity in fuzzy environment.When the demand is fuzzy numbers the stock losses (out of stock losses,the backlog of losses) were discussed,and defined a risk function.Through the risk function gravity in a vague sense,deduced a revised formula of traditional economic ordering quantity.When the demand is a fuzzy-valued functions,Build up the total cost of inventory in the analytic expression through expressed fuzzy-valued function with structured element.when containing fuzzy price mechanism established the model of containing fuzzy price mechanism using the linear expressde structured element.Finally,Through weighted ranking of structured element reversed fuzzy processing,deduced the optimal order quantity and the optimal order period of two model.
