Methodology for testing the risk of deferred maintenance = Methodology for testing the risk of deferred maintenance

Maintenance activity to equipment is very important for production process and safety. It has a vital role to play in reducing the risk associated with some workplace hazards and providing safer and healthier working conditions. However the maintenance activity is an disadvantage for improving production rate, and it`s not good for economic budget. So sometimes the company decide to defer the maintenance activity. In this paper we will talk about the methodology for testing the risk of deferred maintenance. With respect to risk assessment analysis, fuzzy logic is a more efficient methodology. With the help of professional experts, we can define the membership function and precise rule for every considerable variable and every possible condition. To define every possible rule, we can have a total rule as a base rule, and we can define the relative importance and value to make some mathematical calculations. We can use average weighted method to define the precise value of output and the relative risk level. It`s possible to acknowledge the risk of deferred maintenance, and this will help the company to make decisions.
