One of the most important items for better file system performance is efficient buffering of disk blocks in main memory. Efficient buffering helps to reduce the widespeed gap between main memory and hard disks. In this buffering system, the block replacement policy is one of the most important design decisions that determines which disk block should be replaced when the buffer is full. To o...

Most of the brand new items are released on the market with a certain type of warranty. A xed length warranty period is assumed in this paper. A maintenance policy which consists of minimal repair and preventive maintenance is analyzed for the case of known and unknown failure parameters of the item's lifetime distribution. For the second case, two types of Bayesian policies are considered. An ...

In today’s global environment, technology is constantly evolving. Being able to stay up-to-date with the very latest technological advances can be extremely hard to accomplish. As a result of these changes and developments in technology, which often come unexpectedly, consumers are frequently tempted to update their devices to the very latest model. The result is that the life cycle of a produc...

Nowadays the product warranty is considered to be a valuable attribute of the product. It is a tool to enforce the competing power of the producer on the market place. There are two types of problems the product warranty addresses. Firstly, warranty deals with the malfunctioning of the product and, secondly, it addresses the information asymmetry, i.e., the misunderstanding and misinterpretatio...

The regulation by law on recycling economy at the enterprise and ecological industrial park level serves as the base of leveled regulation by law on recycling economy. The recycle of enterprise internal sources is the key for developed countries developing recycling economy. Following the requirements of recycling economy, countries constitute relevant laws and regulations, offering an institut...

In this study, by integrating preventive maintenance (PM) into a two-dimensional warranty region, with customized PM (2D PM) is proposed from the manufacturer’s perspective to reduce cost. The cost of 2D derived. tradeoff between and minimal repair saving obtained choosing proper reliability threshold number PMs, advantage illustrated. Second, post-warranty period, bivariate (BPWM) policy consu...
