. E-Toy Corporation specializes in educational-related products. A new product, the GeoSafari Egyptian Dig (GED) is planned for the forthcoming holiday season, and it sells for $19.95. Projected sales are: 10,000 units if the economy is strong (35% chance); 7,000 in a moderate economy (45% chance), and 4,000 in a weak economy. Because of the seasonal nature of the product, the company will have to discount all unsold items by 55 percent at the end of the season in order to clear the stock.

The company can use one of two production methods [Method A and Method B]. If the items are produced with the existing equipment [Method A], the cost is $8.00 per unit, plus $10,000 fixed cost. Alternatively, special equipment can be leased at $30,000 [Method B]. In this case, the cost per unit is $5.00. Marketing and overhead costs in either case are $4.00 per unit.

a. Construct payoff tables [one for each Method] showing the profit of producing the product under the two plans.

b. Under Method A which alternative [production quantity] should the company choose if it uses expected value criterion?

c. For Method A, what is the expected value of perfect information? Explain what it means.

. 2.Dunstreet’s Department Store would like to develop an inventory ordering policy with a 95 percent probability of not stocking out. To illustrate your recommended procedure, use as an example the ordering policy for white percale sheets. Demand for white percale sheets is 5,000 per year. The store is open 365 days per year. Every two weeks inventory is counted and a new order is placed. It takes 10 days for the sheets to be delivered. Standard deviation of demand for the sheets is five per day. There are currently 150 sheets on hand. How many sheets should you order?
1.4. A machine shop has two machines, A and B. Four jobs need to be processed through machine A first and B second. Job 1 will take one hour on machine A and three hours on machine B. Job 2 will take three hours on A and two hours on B. Job 3 will take seven on A and three on B. Job 4 will take five hours on A and one hour on B. Using Johnson’s rule, in what order should these jobs be done?
1.5You have run a capacity resource profile on your shop. Products have been routed sequentially through resources A, B, C, and D. The capacity resource profile tells you that resource A is scheduled at 95% of capacity, resource B at 80% of capacity, resource C at 130% of capacity, and resource D at 100% of capacity. Assuming that the data we used to calculate the capacity resource profile was accurate, how would you employ the “drum, buffer, rope” thinking?
1.6 You are responsible for an operation that has 12 distinct jobs. Seven of those jobs must be processed in two operations: D and E. All seven jobs must go through D and E in that sequence, i.e., D first and then E. Determine the optimal order in which the jobs should be sequenced through the process using the following times:
Job Process D Time Process E Time
1 9 6
2 8 5
3 7 7
4 6 3
5 1 2
6 2 6
7 4 7

Linear programing( industrial engineering)
Videocomp, Inc., a new manufacturer of cathode ray tube devices (CRT’s) for computer applications,
is planning to enlarge its capacity over the next two years. The company’s primary objective is to
grow as rapidly as possible over these two years to make good on its marketing claims.
The CRT’s are produced in sets of 200 units on modular assembly lines. It takes three months to
produce a set of 200 units from initial chemical coating to nal assembly and testing. To ensure quality
control, none of the units in a set is shipped until the entire set has been completed. Videocomp has
three modular assembly lines and thus currently can produce up to 600 units per quarter. Each set
of 200 units requires $15,000 at the beginning of the quarter when the production is initiated for
purchasing component parts and paying direct labor expenses. Each set produces revenue of $35,000,
of which 20% is received at the time of shipment and the remaining 80% a full three months later.
Videocomp has negotiated the terms for adding modular assembly lines with a number of contractors
and has selected two possible contractors. The rst contractor requires an investment of $60,000 paid
in advance and guarantees that the assembly line will be completed in three months. For the same
assembly line, the second contractor requires an investment of $20,000 in advance and an additional
investment of $20,000 upon completion; however, his completion time is six months.
The present assets of Videocomp for investment in new modular assembly lines and nancing current
operations are $150,000. No further funds will be made available except those received from sales of
CRT’s. However, as the market is expanding rapidly, all CRT’s produced can be sold immediately

using eight planning periods of three months duration each. Should any of the variables restricted
to be integer?
