Using Sensitivity Analysis for Selecting of Ship Maintenance Variables for Improving Reliability of Military Ship

This paper describes the original Analytic Hierarchy Process (AHP) as it is implemented in the software package Expert Choice to select multiple variables that affect the military ship's maintenance. In the ships maintenance management system consists of eight variables: Cost, Availability, Reliability, Safety, Human Resources, Operations, Types of Ships and Ship's Characteristics. The eighth selection of the variables was carried out with a questionnaire spread. A questionnaire distributed to 30 crew for selected variables that can be used in a military ship maintenance management. From the results of a questionnaire is produced 7 variables. The next step is using the Expert Choice that produces the influential variables i.e. HR = 0.246, Cost = 0.222 and Availability = 0.197. The judgments were found to be consistent, precise and justifiable with narrow marginal inconsistency values. This paper also presents a thorough sensitivity analysis to demonstrate the confidence in the drawn conclusions.
