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: Engineers Required Cost ($1,000,000s) 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 Pi=0 or 1 , indicate if project i will not be undertaken or will be undertaken respectively. The most appropriate objective function for Tower Engineering Corporation is given as: Max.50P1+35P2+40P3+45P4+55P5+30P6Min.2P1+3.4P2+2.6P3+2.8P4+3P5+2.5P6Max.2P1+3.4P2+2.6P3+2.8P4+3P5+2.5P6Min.50P1+35P2+40P3+45P4+55P5+30P6 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: Engineers Required Cost ($1,000,000s) 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 Pi=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: 3P1=P2+P4+P62P5>=P2+P4+P6 None of the above. 2P5+1>=P2+P4+P6
