The safety record of most petrochemical industries in the world and Nigeria in particle, has not been able to come down to the maximum allowable range of 0 - 0.1 percent of tolerance on recordable injuries, due to increasing failure rates of equipment within the plant. Investigations on the maintenance audit carried out on the Nigerian Gas Company (NGC) revealed that 85 percent of such failures are directly linked to improper adaptability of an effective maintenance management strategy and plan within the petrochemical industries in Nigeria.

The sensors can inspect several parameters of the equipment which can be generate a Health Index (H) in real time at each inspecting time nd, n=0,1,2,3…The H will be translated into equipment status and saved in the system database. According to the equipment status, we can decide the best preventive actions at time nd by the rule of the lowest total maintenance cost per cycle. The state of the equi

碩士<br>國立臺灣大學<br>工業工程學研究所<br>101<br>Ion implant area is one of the most important processes in semiconductor fabrication industry. The characteristic of this area is that the sequence for different arrival rate of WIP type would affect the variation of machine failure rate. This means the scheduling decision making is just machine maintenance work. Many companies only pursue production efficiency but ignore the importance of maintenance work. We should integrate them simultaneously The main purpose of this study is to construct the unique failure rate estimation model for the machine, and the e

Abstract:
Studies of community water have been on the increase since the International Drinking Water Supply and Sanitation Decade, 1981 - 1990. However there is some key areas of community water supply that still require research as the literature survey in this thesis illustrates. The Operation and Maintenance of community water supplies has been identified to be as important in sustainability of the services as the institutional factors. Due to the increased number of failure of the community water supplies to continue operation after short periods of time compared to urban water supplies, effort is

碩士<br>國立交通大學<br>工業工程研究所<br>84<br>Modern weapon systems are expensive and complicated. Total resources areaffected from mission requirement definition , product design , analysis andmanufacture, to product deployment. This problem is hard to solve usingtraditional analytical methods. In this paper, we proposed a simplified modelalong with a simulation method to simulate operational environments, systemrequirements, and resources allocation to aid in decision-making. This paper
