APPLICATION OF SIMULATION COST MODELLING TO RAILROAD ROLLER BEARING USAGE

This paper describes a dynamic simulation technique for determining costs associated with the use of a component by an economic system. The cost simulation technique is presented with respect to the annual operating cost (i.e., acquisition and maintenance cost) of railroad freight car roller bearings. The three basic pieces of the technique-- schematic diagram, computer program, and data--are discussed for this roller bearing case. A first version of the technique is described: consequently, the paper does not attempt to present the most realistic representation of roller bearing usage or to give the most accurate roller bearing data. Rather the paper illustrates the use and potential of the technique and the information which it can produce. This information includes component-associated costs and system behavior, cost sensitivities, cost benefits, and time-trend predictions.
