A has now crashed. F has now crashed. No further reductions possible in overall project time. The optimal solution is to manufacture 400 Super and 840 Eco models per week. Considering the contribution of the Eco machine C E , we determine how much this can change.
Optimal mix is determined by the slope of the objective function.
I have conducted an investigation into the likely return following the possible purchase of a new scanner or the upgrade of our existing machine. Based on the assumption that you wish to maximise the possible return I therefore recommend you to upgrade the existing machine rather than purchasing a new model. The show-room is staffed by a manager, an accounts clerk, two mechanics and several salesmen. Customers are normally dealt with by the salesmen. The salesmen must however receive the manager's approval before finalising any deals with customers.
