  1. LEGO MY SIMPLEX (Pendegraft, 1997)

  2. Directions • You (Teams,groups of students usually no more than 4) are invited to produce two different products, Tables and Chairs (see Fig. 1, next slide), using the parts received in a bag. • You will work with two different products: the COMMERCIAL(bright colors) and MILITARY (camouflage colors), made identically but with different selling prices. One half of the class will produce military products and the other half, commercial (public) products.

  3. Products: Tables and Chair From Pendegraft, 1997 Tables require two large blocks and two small blocks. The chair requires one large and two small blocks.

  4. The question • Each team has 30 minutes to determine the optimal number of tables and chairs taking account the respective prices and cost given in table I (next slide).

  6. The game can then extend to cover analysis such as: Task Purpose Technique Develop a mathematical model and solve it using excel software Find the best product basket and compare it with the results found empirically in class Simplex/Solver Model debugging Find errors and weakness in the model Re-optimization Final managerial decision on resource allocation Make appropriate division of organizational resources between activities under study and other important activities Shadows prices Evaluate estimates of model parameters Determine crucial estimates that may affect optimal solution for further study Sensitivity analysis Evaluate trade-offs between model parameters Determine the best trade-offs Parametric linear programming Debriefing
