AN IMPERFECT PRODUCTION MODEL WITH PRESERVATION TECHNOLOGY, FUZZY AND VARIABLE HOLDING COST UNDER TWOSTORAGE CAPACITY

摘要

In this paper, we develop a two-warehouse production-inventory model with imperfect quality items. Shortages are allowed and partially backlogged with variable holding cost. The lot sizing problem is then to find the optimal production while minimizing the manufacturer's total cost over the planning horizon. Finally, numerical examples will be used to illustrate the results.
