Abstract: In this research, a new multi-objective-multi-criteria model is presented to determine physical asset management strategy for capital equipment. Initially, a multi-objective model is formulated to determine non-dominated strategies considering cost, reliability, and availability as objective functions. Secondly, the strategies will be ranked based on decision maker preferences and restrictions using a PROMETHEE-entropy module. Each strategy is a vector of procurement variables (dealer-manufacturer and contract type) and maintenance planning variables (PM action level, PM interval and the degree of upgrade action). The multi-objective model, which is a new nonlinear mixed integer optimisation model, is solved using a customised NSGA-II. Buy, lease, rent and upgrading a used equipment are contract types that are considered. The model is used in a real case for determination of asset management strategy for a truck to be used in a mine for 48 months. A piece of software is designed for simplification of using the model.
