ANALYTICAL HIERARCHY PROCESS AND TOPSIS APPROACH TO STRATEGY DETERMINATION OF DEPO LEVEL MAINTENANCE FOR SUBMARINE

Summary/Abstract: Defense Industry Policy Committee (DIPC) and PT.PAL Indonesia projects have not yet determined a strategy in determining the implementation of submarine maintenance. Availability of the budget in carrying out maintenance and repair of submarines is one of the obstacles that is quite difficult in carrying out scheduled and planned maintenance of the defense equipment. On the other hand, if a policy is implemented to carry out continuous maintenance, it will result in a very high maintenance budget burden. Based on the current conditions and several previous studies, this study aims to provide an analysis of development strategy priorities in determining submarine maintenance. This study uses the MCDM Hybrid Technique approach combining the Analytical Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods. While the AHP method is applied in screening decision criteria and determining the weight of each decision criterion, the TOPSIS method is used in ranking alternative maintenance strategies. Based on the results of the study, the criteria for the maintenance strategy on the Submarine showed that the safety level criterion (C4) had the highest weight of 0.201 with a CR of 0.097. Then the Technology Use criterion (C3) weights 0.143 as the second criterion. The resource availability criterion (C7) is the third criterion with a weight of 0.135. While the Operational Time criterion (C5) weighs 0.056 as the criterion with the smallest weight. Submarine-02 with the Medium category maintenance strategy. Submarine-03 with a medium-level maintenance strategy weight of 0.633. Furthermore, Submarine-01 and Submarine-04 are currently still in the Corrective level maintenance category with respective weights of 0.279 and 0.344.
