Implementing FAHP-BSC integrated approach for evaluating the performance of maintenance and repairs system in Nina plant oil company

Nowadays, designing and evaluation of maintenance systems and repairs is one of the critical issues in industry. Evaluation methods that exclusively rely on financial measures are not suitable for these systems. The aim of this research is to apply an integrated approach of fuzzy analytical hierarchy process (FAHP) and balanced score card (BSC) for evaluating the maintenance and repairs systems in Nina company in Sirjan. The concept of BSC is defined in the hierarchy based on 4 aspects of financial aspect, customers’ aspect, internal processes aspect, and growth and learning aspect and indexes under each aspect are selected. Then, FAHP is used for weighing and prioritization of indexes/indicators. Results show that among all these aspects of balanced score card of maintenance and repairs systems, growth and learning has the least priority over other aspects. In addition, among all indexes, the indexes of equipment's overall effectiveness, the percentage of employees’ participation in professional and technical net courses, and the percentage of employees’ satisfaction play an important role in the performance of the maintenance and repairs systems. The results of this research can be beneficial and useful for industrial managers and experts and assists them in making correct decisions and appropriate strategies in future.
