Designing of Computerized Maintenance Management Information System and Root Cause Analysis for National Fertilizers Limited, Panipat, India

The present paper deals with designing of Computerized Maintenance Management Information System (CMMIS) for a fertilizer plant and applied Root Cause Analysis (RCA) with CMMIS. The computer software was developed in Microsoft Visual Studio.NET. The developed computer software is versatile, less complicated, less costly and less time-consuming and consists of a number of modules like equipment detail, critical issues, work order, maintenance schedule, safety records, tools and tackles, employees, literature related to maintenance and reports, etc. Firstly, a list of plant requirements was created, such a system was conceptually designed, and finally an object-oriented model was built based on the conceptual design. RCA makes it more effective to highlight the main or critical root cause of the maintenance problem. The currently developed software ‘CPP CMMIS’ aims to have an informational tool for maintenance activities; to reduce total downtime, overall annual maintenance cost and frequency of failures of the machines; and to get day-to-day maintenance schedule
