Abstract:

In this paper a methodology for selection of optimal machine tool configuration by simultaneously considering reliability and maintenance is developed. Methodology is based on measures like Life Cycle Cost (LCC), Availability (A) and Overall Equipment Effectiveness (OEE). These measures explicitly consider the user’s cost structure and shop floor level policy parameters. A simulation based Genetic Algorithm (GA) is used to solve the simultaneous optimization problem. Case example using operations and maintenance data of a CNC grinding machine is presented.
