Chapter 14, Problem 8P
Refer again to Problems 14.3 and 14.4. In addition to 100 units of S, there is also a demand for 20 units of U, which is a component of S. The 20 units of U are needed for maintenance purposes. These units are needed in week 6. Modify the gross material requirements plan to reflect this change.
• 14.4 Using the information in Problem 14.3, construct a gross material requirements plan.
•• 14.3 The demand for subassembly S is 100 units in week 7. Each unit of S requires 1 unit of T and 2 units of U. Each unit of T requires 1 unit of V, 2 units of W, and 1 unit of X. Finally, each unit of U requires 2 units of Y and 3 units of Z. One firm manufactures all items. It takes 2 weeks to make S, 1 week to make T, 2 weeks to make U, 2 weeks to make V, 3 weeks to make W, 1 week to make X, 2 weeks to make Y, and 1 week to make Z.

The company obviously does not have the resources available to manufacture
everything needed for the completion of 24000 tricycles so has gathered
purchase information for each component.
Requested:
Develop a linear programming model to tell the company how many of
each component should be manufactured and how many should be
purchased in order to provide 24000 fully completed tricycles at the
minimum cost.

- Q7. The president of Rose Bowl Enterprises, Desmond Howard, projects the firms aggregate DEMAND requirements over the next 8 months as follows: These are the monthly DEMAND, not production. MONTH JAN FEB MAR APR MAY JUN JULY AUG DEMAND 1,400 1,600 1,800 1,800 2,200 2,200 1,800 1,800 PRODUCTION 1,600 from December INVENTORY 200 from Dec plus 200 His operations manager is considering a new plan, which begins in January with 200 units on hand. Stockout cost of lost sales is $100 per unit. Inventory holding cost is $20 per unit per month. Ignore any idle time costs. The plan is called plan A. Plan A: Vary the workforce level to execute a strategy that produces the quantity demanded in the prior month. The December demand was given as 1,600 units per month. Therefore, the production for JAN will be 1,600. However, only 1,400 are needed. Therefore, the extra 200 produced go into inventory and there is a holding cost for inventory. Also, per the above, you already have 200 units in inventory…arrow_forward1. Identify some reasons for ERP failures? 2. Explain the chain of events from quality to profits. 3.
