| Popis: | 107 Because of updating of technology, the same type of products in new generation will be launched at regular interval. The old generation products currently on the market will no longer be sold after new generation products released for a period of time. Then, there will no old generation products in the market. When there are new and old generation products on the market at the same time, consumers will consider various factors to replace old generation products with new generation products, which is called “switch-over.” In practice, the products are degraded. As the usage increases, the failure rate of these products may increase the opportunity of failure occurs in products then makes products do not work. This paper purposes the products which divided two types. The first one are repairable products, when the products fail, which performing minimal repair to restore the products to normal status. According to the usage increases of products, the number of failures will increase to result in excessive repair costs. Then, we will perform replacement actions to change a new product. The second one is non-repairable product. When the products fail, we will perform replacement actions directly to replace with new products. This paper purposes to find switch-over time for the products which have old and new generation products on the market. Therefore, the mathematical model of switching over to new generation products is established to minimize the total costs and find the optimal switch over time. Finally, the impact of the relative costs of new and old generation products on the switch over time is demonstrated through numerical examples. |
