The inventory with constant demand rate is managed by a （r; q1, q2, · · · , qm） policy and supplies from an unreliable sole supplier. By renewal theory and matrix Geometric method, the long-run average cost function is obtained and some important properties of the function are proved. Furthermore, performance of the inventory is derived.展开更多

In thispaper, a complicated order quantity problem is studied and an order quantity simulation system isestablished with the simulation software of ARENA. Finally, an example is given.展开更多
