Economic Order Perishable Items with Demand Dependent to Inflation

In most inventory models, assumed that the items can be unlimited in time, stored for future demand and their quantity and quality does not change over time, however, certain types of product that, over time has deteriorated or are unusable, such as foods, human blood, alcohol, drugs and so on. As a result if the decay rate is significantly amount, its effect cannot be neglected. In mathematical modeling, inventory control problem, that began with classic problem economic order quantity of Harris [1], it is assumed that the products have infinite life. Considering corruptibility product, for the first time for inventory obsolescent, after specified time was raised by Whitin [2] .Goyal and Giri [3] began to categorize, Inventory control models, based on corruptibility. They divided, inventory control models by investigation 130 sources, based on existence or non-obsolescent and corruptibility. Including comprehensive articles, that have been done in the field of corruptibility items, can be noted to research Bakker et al. [4] other articles in which, to consider hypothesis corruptibility products, that have been discussed can be noted to researchers Jolai et al.[5] in 1384, Mirzazadeh et al.[6] and also Jolai et al. [7] in 2011.In addition corruptibility, other important assumptions in inventory control models, can be noted to allow or not allow shortage. Including primary articles, which considered, allowed shortage in inventory control problem can be noted to, Zipkin article [8] in 2000. Pentico and Drake [9] in 2011 have reviewed, articles literature, related to shortage topic in the last 40 years.
