Answer the next five questions based on the case given below: Tower Engineering Corporation is considering undertaking several proposed projects for the next fiscal year. The projects, the number of engineers and the number of support personnel required for each project, and the cost for each project are summarized in the following table: Projects Engineers Required Cost ($1,000,000s) 1 50 2.0 2 35 3.4 3P1 <= P2+ P3 + P4 + 1 3 4 5 40 45 55 2.6 2.8 3.0 6 30 2.5 Formulate an integer linear program that minimizes Tower's cost, subject to constraints, which will be stated in the questions that follow. No more than 150 engineers can be used. Let P₁ = 0 or 1, indicate if project i will not be undertaken or will be undertaken respectively. Project 1 can be completed only if at least two out of Projects 2, 3 and 4 are completed first. The constraint that captures this is: OP1 <= P2+ P3 + P4 OP1 <= 2P2 + 2P3 + P4-2 2P1 P2 + P3 + P4 2P1 P2 + P3 + P4 and 3P1 <= P2 + P3 + P4 + 1 would both work.

No more than 150 engineers can be used. Let P₁ = 0 or 1, indicate if project i will not be undertaken or will be undertaken respectively. 2P5 >= P2 + P4 + P6 1 3 50 40 2.0 3.4 2.6 Project 5 is not completed, then at most one out of Projects 2, 4 and 6 can be completed. This requirement is represented by: None of the above. 2 35 O2P5 + 1 >= P2 + P4+ P6 4 5 45 55 2.8 3.0 6 30 2.5
