Managers in mega corporations like General Electric, Ford Motors, Motorola etc, use it in their six sigma projects. It is for this reason that AHP is one of the most sought after technicques in management science today. These checks and balances, therefore ensure that you reach logically consistent solutions when you compare the relative importance of the criteria in the process of assigning weights to them. The AHP method has inbuilt checks and balances. As the number of criteria (factors) multiplies, the assignments become more and more arbitrary. In the above example, our assignment of weights was arbitrary.

However, until very late management scientists have been facing issues as to how to assign weights. Hence, while evaluating alternative solutions, weights need to be attached to the criteria to ensure reaching the correct conclusion. Therefore if you assign weightage of 2 to taste and 1 to waiting time, you are more likely to arrive at a restaurant that will best meet your need. The taste may ne far more important than the waiting time and so on. For instance if you have to choose between two restaurants, the taste and the waiting time are two factors, however both of them may not have equal importance in your perception. The AHP method understands that although there are several criteria, the magnitude of each criterion may not be equal. The third and the most important part as far as the AHP method is concerned is the criteria used to evaluate the alternative solutions. The first part is the issue that needs to be resolved, the second part are the alternate solutions that are available to solve the problem. The AHP method looks at the problem in three parts. This structure has been explained in this article. The AHP method has been created after understanding the structure of a problem and the real hindrance that managers face while solving it. It was observed that factors “Implementation of preventive and prognostic service strategies”, “The usage of M&O data collection and processing systems”, and “Modernization of machines and devices” are the major factors that support the realization of sustainable manufacturing process challenges.What is Analytical Hierarchy Process (AHP) ?Īnalytical Hierarchy Process (AHP) is a mathematical tool of problem solving that has become popular amongst management personnel in the late 1990s and early 2000s. A numerical example is provided to demonstrate the applicability of the approach. In the last stage, the results of MICMAC and F-AHP analyses were used as inputs for the fuzzy technique for order preference by similarity to ideal solution (F-TOPIS) to generate aggregate scores and selection of the most important maintenance factors that have an impact on sustainable manufacturing processes. In the third stage, the criteria for evaluation of maintenance factors were defined, then the fuzzy analytic hierarchy process (F-AHP) was applied to determine their relative weights. Then, in the second stage, the matrix of crossed impact multiplications applied to a classification (MICMAC) was carried out to categorize these factors based on their influence and dependence values. At first, ten factors of maintenance activities from a sustainable manufacturing point of view were identified. The work methodology comprises four stages. This paper presents an empirical study on the impact of maintenance function on more sustainable manufacturing processes.
