Abstract:

An optimal economic replacing algorithm is introduced, it can avoid disadvantages of emphasizing particularly on performance criticality but neglecting cost occurred in the replacing algorithms based on the age and the performance degradation degree. An optimal performance inventory control algorithm is put forward, it can overcome the demerits of ignoring the technical depreciation and capital overstocking processed by the inventory control algorithm based on the minimal total expense. Simulations show that they can largely reduce the total cost and the capital overstocking.
