Abstract
An operational research project at the Oskarshamn plant of Saab Scania AB Truckdivision Sweden is reported, The decision problem concerns th e product mix of sheet metal purchased. A mathematical model that appr oximates the real-world problem is derived, the solution of which incl udes a p-median problem. This optimization problem is solved using Lag rangean relaxation and a subgradient optimization procedure. Numerical results for problems of real-world size and structure are reported an d indicate satisfactory efficiency.
