Contract costing in outsourcing enterprises: Exploring the benefits of discrete-event simulation

Outsourcing is a business strategy that has received much attention. An increase in outsourcing has a direct influence on the complexity of supply chain networks and on the number of contracts required to manage a supply chain. Outsourcing contracts may be entered into relatively quickly without a full understanding of the true cost implications. The research described here aims to develop tools based on discrete-event simulation to aid outsourcing companies when costing contracts. Currently available software for this type of application is reviewed. A field study is presented from the electronics sector, describing companies' needs with respect to contract costing and how simulation could be used in the contract costing process. Simulation approaches are described for different contract costing scenarios. The paper concludes with a case study of a preliminary simulation model that has been developed to test the concept with a specific outsourcing scenario.
