In this paper it is suggested that an effective way to teach the introductory management science/operations research course is to tie together techniques in solving some fairly complex, realistic problems. A multistage process of analysis called the combined‐methodologies approach (CMA) is proposed. A queueing design problem is given as an example. Its solution requires the use of simulation, regression analysis, and goal programming. The particular techniques applied under CMA are specific to the situation under study. The authors believe the approach will increase student interest and address some criticisms of MS/OR instruction in universities.
