A production-remanufacturing inventory model with fuzzy random demand

The classical inventory control model with remanufacturing assumes that items are produced by perfectly reliable production and serviceable items with the determined demand. However, in reality, products are not always perfect but are directly affected by the reliability of the production process employed to manufacture the product. In this paper, a production inventory model with remanufacturing is developed in an imprecise environment. We extended the inventory model for the case of quality consideration and assumed that all returned items and imperfect items produced are remanufactured. And the model is to introduce demand as a fuzzy variable. A numerical example is considered to illustrate the model.
