Study On Decision-Making In Enterprise Equipment Maintenance Under The Mode Of E-maintenance

The mechanic who wishes to do his work well, must first sharpen his tools. The effective equipment maintenance management is not only the important factor to working order, but also the key content of improving the invest benefit. In order to fit such new demand, enterprise keeps adopting new maintenance management system and the modern detecting and diagnoses technique to improve the equipment reliability and reduce the cost.E-maintenance integrates the newest network and state-monitoring and remote diagnoses maintenance technique to realize maximum of the maintenance benefit through optimizing the allocation of maintenance resource and working flow management. However, its collaboration work mode based on dynamic alliance increases the equipment's reliability and efficiency, but make the maintenance management and decision-making more complex at the same time. Based on the characteristic of e-maintenance, this paper studies the system of maintenance decision-making, the influencing factors, methods and the decision support system (DSS).Firstly, from the view of user and manufacturer, this paper summarizes the problems in the traditional maintenance management and points out the significance of the e-maintenance Then the whole system and technique supporting of the e-maintenance application was proposed in the following five aspects: demand, methods and theory, business supporting, application technique and the supporting flat. This paper summarizes the five main characteristics of the e-maintenance as the following: pertinence, dynamic, intelligent and alliance.Then, this paper studied the decision mechanism and carries out the influencing factors analysis from equipment itself, inner resource and outer collaboration. Based on the comprehensive consideration of strategy layer, tactics layer and operation layer, a total framework of enterprise equipment maintenance decision based on e-maintenance was pointed out.Thirdly, because maintenance undertaker decision, maintenance mode decision and the maintenance type decision are the key problem among the decision framework, so this paper emphases on analyzing and modeling this three decision with logic judgment, techno-economic analysis, AHP, FCE, and so on .Finally, this paper designs the enterprise equipment maintenance decision support system under the mode of e-maintenance, and present its system structure and total function structure.
