Schweinsteiger Limited produces two models of handmade table football sets (SETI and SET2). For the next period, a contribution of 120 per SETI, and 200 per SET2 is expected. Maximum sales are expected to be 200 units of SETI and 85 units of SET2. During production, SETI and SET2 need to pass through the carpentry, painting and assembling department. The following information is available as regards the required input for the production: SETI SET2 Capacity 1 Carpentry Painting Assembling 6 hrs./unit 3 hrs./unit hrs./unit 3 hrs./unit 4 hrs./unit 4 hrs./unit 840 hrs. 480 hrs. 360 hrs.

Identify the optimal production pattern and the corresponding level of contribution, using the graphical solution of linear programming. 9 Marks c) Discuss the possible effect of 60 additional hours overtime in the painting department on production levels and overall contribution. Amend your chart diagram accordingly. Assume that the extra time comes with an additional cost of 20 per hour. 4 Marks d) Critically describe in which ways linear programming can contribute to managing scarce resources in a company. 6 Marks Total 25 Marks
