Traditional preventive maintenance policies, such as age replacement, periodic replacement under minimal repair, and replacement policy N, are all studied based on the expected cost criteria without considering the management risk due to the cost variability. As a result, these policies could be significantly beyond the anticipated maintenance budget allocation and lead to crisis. In order to s...

The purpose of this study is to determine the type failures, causes, as well efforts and proposed actions that can be taken improve performance pneumatic system CNC milling machines. Failure Mode Effect Analysis (FMEA) method used find priority problems through Risk Priority Number (RPN) for components machine. results critical component analysis were a leakage occurs in valve component, which ...

In this paper we discuss a dynamic efficiency measurement model for evaluating the performance of highway maintenance policies where the inter-temporal dependencies between consumption of inputs (i.e., maintenance budget) and realization of outputs (i.e., improvement in road condition) are explicitly captured. We build on a micro representation of pavement deterioration and renewal processes an...

Maintenance resources are important part of the maintenance support system. The whole efficiency of weapon system is directly affected by the allocation of maintenance resources. Joint support for weapon system of multi-kinds of equipments is the main fashion of maintenance support in the future. However, there is a lack of the efficiency tools and methods for predication and optimization of we...

The multimedia enabled Grid (MEG) is an extension of the Grid concept to support the deployment of multimedia services. To provide an adequate level of service to multimedia applications, it is often necessary to simultaneously allocate the resources including predetermined capacities from the interconnecting networks to the applications. The simultaneous allocation of resources is often referr...

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 ...

The transmission delay is an important index of the system performance of NoC (Network on Chip). Although the method of simulation-based can get accurate transmission delay, the simulation requires time consuming and a large number of test vectors. Especially in the study of some algorithms, such as mapping algorithms, buffer allocation algorithm, the simulation method is not applicable. To sol...
