Developing a Model to Evaluate Maintenance Operations

Maintenance has become a prominent function in today's manufacturing environment. Tremendous efforts have been put into in developing different types of maintenance strategies for enhancing the performance of the equipment but very little has been done in actually streamlining maintenance activities. This refers to systematically evaluating and analyzing the non-value added activities within the maintenance function. One of the primary lean tools that can provide a different dimension in identifying and analyzing non-value added activities is Value Stream Mapping (VSM). However, the traditional VSM cannot be utilized "as is" because the maintenance activities do not completely correspond with VSM terminology. The purpose of this thesis is to develop a simulation based maintenance value stream mapping model to identify and analyze the non-valued activities within the maintenance function.
