Problem 2: Assignment Problem A contractor is assembling a crew with six positions. The contractor will select the six people from among a dozen of firm's employees who are willing to travel. Each of the dozen people who are eligible for the assignment has been ranked according to effectiveness in each of the six slots. The selection problem is to choose the ix crew members from the 12 eligible employees in such a way that the crew's total effectiveness is maximized. You are given the effectiveness eij of the ith eligible employee in the jth position on the crew. in all 72 parameters. The decision variables are Tij = 1 of eligible employee i is chosen for the jth job on the crew, and 0 otherwise. Formulate this problem as an LP (continuous variables) and solve via CPLEX (Arbitrarily generate en). Employee five and employee nine, have a longstanding dislike for one another. that makes them ineffective when working together and disruptive of the work of others. How would you modify the formulation? Solve via CPLEX
