Maintenance Strategy and Decision Making – Ahp Method

چکیده
Maintenance strategy plays a very important role in all kind of manufacturing industries. Each maintenance strategy has their characteristics, importance and drawbacks. Performance of a machine depends on the type of maintenance strategies employed on it. Machines used in industries need proper maintenance because failure of machine may cause the production loss. Maintenance strategy may vary from one machine to another machine because of the various conflicting factors like safety, cost, customer satisfaction etc. Factors affecting machines performance need to identify and control. Use of inappropriate maintenance strategy may increase the maintenance cost. Increase in maintenance cost will increase the production cost. Selection of a maintenance strategy to a particular machine or group of machines is a problem of decision making and it is always a challenging task for maintenance Manager/Engineer. By using the decision making tools like AHP, this problem can be solved. Use of AHP method also facilitates to calculate the weight of factors through which decision maker can analyze the difference between actual condition and required condition. Present research work shows that the problem of selecting an optimum maintenance strategy to a machine can be overcome by using decision making tool (AHP).

In pavement management, prioritized resource allocation is imperative given the fact that there is rarely enough funding with highway agencies to address all the pavement sections. In view of the complexity involved in the decision making process, subjective evaluation based on expert’s judgments is unavoidable. Analytic Hierarchy process (AHP) has been applied by researchers to solve pavement ...
