Case
Mfa Company operates a centrally located storeroom in their manufacturing complex. Every afternoon, each craft foreman (Tin Shop, Electric Shop, Iron Workers, etc.) writes a requisition for common use items include nuts, bolts, screws, washers, flashlight batteries, and gloves. All specialty items are ordered separately.
During the night shift, the storeroom personnel fill the orders items requested by the craft foreman. Each morning, one or two workers from each department to go the storeroom with a four –wheel platform truck to pick up the filled order.
Question:
Although studies have been performed to determine the amount of time craftsmen spend waiting the supplies, it is the thoughts of the management that idle craft manpower is a problem resulting from this procedure. How can time spent traveling and from the described storeroom be reduced, thus, eliminating or decreasing crafts’ personnel travel time?
) The following data have been prepared for master production scheduling purposes in IKEA Australia:
End product A: Beginning inventory of 60, Period forecast of 10, Lot size of 30, and 30 hours in lot size.
End product B: Beginning inventory of 20, Period forecast of 5, Lot size of 20, and 20 hours in lot size.
End product C: Beginning inventory of 30, Period forecast of 15, Lot size of 50, and 50 hours in lot size.
Capacity: 38 hours/ week
(i) Prepare the master production schedule for these items during the next four periods using the Ethan Allen master production scheduling method.
(ii) Suppose that the master production schedule is frozen for the next three periods. What specific impact would the policy have on the IKEA's performance?

Three machines are available for the manufacturing operations. All three machines can produce all the products at the same production rate. However, due to varying defect percentages of each product on each
machine, the unit costs of the products vary depending on the machine used. Machine capacities for the next week and the unit costs are shown below.

The three process centers of modelling, curing and assembly has an available production time per day of 12 hours, 14 hours and 16 hours, respectively. To produce one hundred units of Concert, the time required for the process of modelling, curing and assembly is 2 hours, 3 hours and 2 hours, respectively. To produce one hundred units of Soprano, 2 hours of modelling, 2 hours of curing and 1 hour of assembly is required.

Product XB has a sales potential in the market; hence, some of it can be sold at the end of Stage 2, and the remaining can be moved to Stage 3. The third stage produces Product XC, and then delivers it to customers. Two units of Product XA produced in Stage 1 are required for each unit of Product XB in Stage 2. In addition, four units of Product XB produced in Stage 2 are required for each unit of Product XC in Stage 3. Stage 1 can only use regular time; however, Stage 2 has the options of using regular time and overtime in manufacturing. On the other hand, Stage 3 has only one alternative, which is subcontracting.

- A manufacturer produces three models (I, II, and III) of a certain product using raw materials A and B. The labor time per unit model of I is twice that of Il and three times that of III. The entire labor force of the factory can produce the equivalent of 1500 units of Model I. Market requirements specify the ratios 3:2:5 for the production of the three respective models and minimum demand levels should be satisfied.
