摘要:

In this paper multi-stage flow lines with intermediate buffers are approximated by two-stage lines by using repeated aggregation. The aggregation method uses restricted information of the output pattern of two-stage lines. The method is tested for the case where all production units are unreliable with exponential life-and repair-times. It appears that it performs well for most cases, provided we aggregate in the correct sequence.

摘要:

In this paper a heuristic procedure is developed to determine the optimum inventory policies for an inventory system consisting of a single product and raw materials used in the manufacture of the product. The raw materials are optimally classified into groups so that the total inventory cost per unit time is minimized. The cost expression used as the objective function takes the inventory relationship between the product and its raw materials into consideration.
