Question

1. What are the steps involved in problem solving process? 2. What are the common characteristics of optimization problems? 3. If there is no way to simultaneously satisfy all the constraints in an LP model the problem is said to be: a. infeasible. b. open ended. c. multi-optimal. d. unbounded. 4. When the objective function can increase without ever contacting a constraint the LP model is said to be... e. infeasible. f. open ended. g. multi-optimal. h. unbounded. 5. Consider the following LP problem. MAX: Subject to: 2X+3X,$120 4X,+3X, $ 140 Xi+ X 80 Xi, X, 20 a. Sketch the feasible region for this model b. Explain whether any feasible region exists for this problem or not?

Explanation / Answer

Dear student, as per Chegg guidelines please post one question in one thread. You may post rest of the question or parts in a separate thread. I will be happy to help you. Thanks.

Solution of question 1:

Six steps of problem solving:

The six steps of problem solving are as follows:

Explanation to each step:

One must be totally through with the pros and cons of the problem before going ahead with it. The following are the parameters on which the best alternative is decided.

5. List the instructions that enable you to solve the problem using the selected solution : Instructions, which are listed properly helps one to refer to them for guidance. This increases the efficiency of the task in hand and also saves time, cost etc.

6. Evaluate the solution : To evaluate a problem means to check whether the solution of a problem is correct. The solution must be reviewed in proper detail so that the evaluataion can be completed efficiently and quickly.
