This paper describes a new and integrated approach for providing an accurate and reliable estimation of work orders production costs meant to ease customers? bid preparation. For many small and medium third-party service providers, facing almost homogeneous product portfolio and a finite number of production lines, is really worthwhile to provide a precise production costs estimation as a basis for further decisions to accept or reject an order. Because of information on processing times are tough to be estimated in such companies, the idea was to integrate the discrete event simulation technique, providing accurate and reliable process evaluations, with the operation costing technique to assess orders production costs. A new tool called ?cost simulator? was developed based on this integrated approach and it was validated on a real industrial case in the wooden painting sector.
