Question 1
The Pulsometer Pump Company makes concrete pumping equipment for the European market and is at present operating at near production capacity. The sales and marketing director of the company anticipates that the market for concrete pumps will increase by 15% during the next twelve months. The board must decide how to react to this change in demand. There are three strategies that are being considered
S1 Install new equipment to improve productivity with a new system of working
S2 Institute overtime and weekend working
S3 Continue to work at capacity and let rivals or new firms satisfy the increased demand
A decision matrix can be constructed to show information (all column show profits, in £000s).

Use the Pay-off Matrix to make the decision and inform what decisions should the board take? The company board is satisfied with the pay-off procedure however they are not confident with your decision. The sales and marketing director of the company now decided that "we need the probabilities associated with the change in market demands". The probabilities are

Calculate the Expected Monetary Value Analysis (EMV) for each strategy and use the decision tree to show the best option. The board is impressed with the decision method which has informed their decision making. They have assigned you to further investigation on the decision due to variability of returns and further measure of the degree of risk. You need support to do further investigation so that you can examine the sensitivity of decisions. A firm of consultants offers to survey the market for concrete pumps. This survey will lead to a revision of prior probabilities estimate of the likely market outcome. The survey will cost the company £5,000. The consultancy predictions records are shown below

Hint:The sum of getting a `Rise report` is given by the sum of the probabilities of getting a `Rise report` under each outcome multiplied respectively by the probability of getting that outcome.
Use the Bayes Theorem to revise the consultant`s prediction. Should you choose to pay for this additional information? Produce a revised Decision tree for the board to make a decision. You should discuss your decision on to use or not to use the consultant firm and each strategy.your decision on to use or not to use the consultant firm and each strategy.
Question 2:
Refer to the Gulf Golf Problem described in the Lecture sessions, suppose that management encounters each of the following situations:
a. The accounting department revises its estimate of the profit contribution for the deluxe bag to $18 per bag
b. A new low-cost material is available for the standard bag(S), and the profit contribution per standard bag can be increased to $20 per bag. (Assume the profit contribution of the deluxe bag(D) is the original $9 value)
c. New sewing equipment is available that would increase the sewing operation capacity to 750 hours (Assume 10S + 9D is the appropriate objective functions)
If each of these conditions is encountered separately, what are the optimal solution and the total profit contribution for each situation?
Question 3:
As part of a quality improvement initiative, government employees complete a three-day training programme on teamwork and a two-day training programme on problem solving. The manager of quality improvement requested that at least eight training programmes on teamwork and at least ten training programmes on problem solving be offered during the next six months. In addition, senior-level management specified that at least 25 training programmes must be offered during this period. A consultant is used to teach the training programmes. During the next six months, the consultant has 84 days of training time available. Each training programme on teamwork costs £10,000 and each training programme on problem solving costs £8000.
1. Formulate a mathematical model that can be used to determine the number of training programmes on teaming and the number of training programmes on problem solving that should be offered.
2. Graph the feasible region.
3. Determine the coordinates of each extreme point.
4. Solve for the minimum-cost solution.
Question 4
Refer to the Table 1 and do the following:
1. Calculate the Expected time, mean time.
2. Develop the Network diagram using the expected time and use PERT Analysis to know the mean and Sd of the project.
3. Based on these estimates and the resultant expected project duration of 69 days. The executive committee wants to know what is the probability of completing the project before a scheduled time of 68 days?
4. How do you measure project risk exposure? Explain and propose ways to reduce the project risk exposure.
