Abstract: The classical (crisp) inventory control model with reliability influence demand and partially backlogged items is to be considered. The primary motive of efficient inventory management is to provide a suitable customer service thereby keeping a low inventory cost for the model. The cost factor is to consider a fuzzy random variable. Here the ordering cost and reliability of the production process are the decision variables. Thus the aim of this paper is to minimise the cost of the inventory system. This model has been developed for both crisp and fuzzy systems. Due to fuzzy parameters, the model becomes a fuzzy quantity and it is fuzzily by sign distance method. The facts used in this research work have been exemplified by the use of an appropriate numerical example.
Keywords: deterioration; fuzzy inventory system; partial backorder; reliability; shortages; signed distance method; trapezoidal fuzzy number.
