Simplification of evaluation methodology for ship’s PMS database

This paper describes testing of simplified evaluation methodology for ship’s computerized Planned Maintenance System database. The simplified evaluation methodology is developed using the efficiency analysis of the evaluation methodology for ship’s computerized PMS database. Evaluation methodology for ship’s Planned Maintenance System database is designed to enable shipowners and their responsible persons for control the PM system development of correct computerized database. The evaluation methodology is used for the development and analysis of computerized databases in nine shipping companies, where it showed to be useful tool for the process of developing new databases and checking existing databases as well. Analysis of the process indicated that the methodology can be simplified with maintaining a high degree of accuracy. An improvement of the evaluation is suggested in three cases, consisting of the simplification of the evaluation grades. Two grades should be used for evaluation, 0 and 1, instead of 1 to 5. Grade 0 should be used when database quality is not satisfactory and 1 when database quality is in order. The analysis of the application of the simplified database evaluation methodology has determined elimination of the subjectivity of a person who evaluates the database that increases the accuracy of the evaluation system. The usability of simplified evaluation methodology is determined by analysis of the results of the evaluation obtained by the testing.
