Abstract

Historically, production of ships is based on Group Technology (GT) with product oriented work breakdown structure. Recent GT applications have been effectively adapted to ship maintenance operations. In this thesis we have developed a GT based classification and coding system for the three basic requirements for maintenance operations: personnel, resources and space.

Traditionally unplanned maintenance activities are executed as and when the resources are available. This thesis presents a method for planning and scheduling these jobs with many of the traditional Lean manufacturing principles first adapted appropriately and then applied to Lean Maintenance. This method begins with identifying the priority levels of all maintenance requests. Then personnel, resource and spatial requirements of the jobs are identified using the GT based classification and coding system. Personnel and resources are assigned to jobs by applying concepts of Lean. Finally, these jobs are scheduled according to their priority level.

A C++ computer program has been developed for scheduling jobs. Two case studies represent detailed examples of planning and scheduling using the above described method.

This thesis is an attempt to bring in Lean principles, GT and a workable strategy for conflict resolution to solve realistic unplanned maintenance problems.
