Suppose that a decision maker is faced with four decision alternatives and four states of nature develops the below cost payoff table. If the decision maker knows nothing about the of the probabilities state find the decision he should select following the minimax regret approach Which of the following is nit true about and assignment problem? A. It will have all supplies and all demands equal 1. B. It will have a non-integer optimal solution. C. It can have maximization objective function. D. It Will have diction variables being briary. A retailer considering investing in several projects from which to select. The total number of projects is 9 let ti=1 if project I is selected 0 if not for all I=19 the following (1) if the project 3 is selected, project 9 must be selected and if project 9 is selected project 3 must be selected (2) if project 5 is selected, project 1 must be selected and fi project 1 is selected project 5 must be selected the constrains for these two restoration are: A. (1)1-r3 399,(2) t5-t1 B. (1) r39,(2) t5-t1 C. none of the above or below choices is correct. D. (1) r3+r91,(2) t1t5 Which of the following statement is not true? A. The reduced cost is the amount by which an objective function coefficient of a decision variable would have to decrease before that variable can assume \& positive value in the optimal solution. B. If a shadow price is negative, a unit increase in the right-hand side value of a constraint will decrease optimal objective function value C. The optimal objective function value can be found in the Answer Report generated by Excel Solver. D. The range of feasibility is the range over which the shadow price is applicable Suppose that a decision maker is faced with four decision alternatives and four states of nature develops the below profit payoff table. If the decision maker knows nothing about the of the probabilities state find the decision he should select following the minimax rearet approach
