The importance in promoting, sustaining industries, manufacturing systems and economy through reliability measurement has become an area of interest. The profit of a system may be enhanced using highly reliable structural design of the system or subsystem of higher reliability. On improving the reliability and availability of a system, the production and associated profit will also increase. Re...

Maintenance can be the factor of either increasing or decreasing system's availability, so it is valuable work to evaluate a maintenance policy from cost and availability point of view, simultaneously and according to decision maker's priorities. This study proposes a Partially Observable Markov Decision Process (POMDP) framework for a partially observable and stochastically deteriorating syste...

System D is a distributed transaction-processing system which addresses the problems of data integrity, system availability, and incremental growth. It is an experimental research vehicle and has been prototyped on a local network of loosely coupled minicomputers. This paper describes the architecture of the system. Novel features of System D include the distributed Resource Manager that provid...

Since lean concept has appeared many works have been done on decreasing or even eliminating of wastes such as extra inventory. Although these studies have not taken into account expected availability seriously. So in this paper, a Multiple Objective Decision Making (MODM) model has been developed by viewpoint of these subjects. They are decreasing wastes and increasing system availability. Wast...

This survey report highlights the main topics associated with availability benchmarking of computing and data storage systems. Compared to performance benchmarking, availability is still in its infancy. A widely adopted benchmarking framework has yet to be designed. This is partly due to the complexity of such a task and the problems associated with it. Numerous factors have to be taken into ac...
