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.
