Chapter 11, Problem 10P
eXcel 10. The Ban go Toy Company produces several types of toys to seasonal demand. The
A regular employee can produce $10,000 worth of toys per month, and the company has so regular employees at the end of June. Regular-time employees are paid $3800 per month, including benefits. An employee on overtime produces at the same rate as on regular time but is paid at 150 percent of the regular pay. Up to 20 percent overtime can be used in anyone month. A worker can be hired for $1000, and it costs $2000 to layoff an employee. Inventory carrying costs are 30 percent per year. The company wishes to end the year with so employees. Beginning inventory of toys is $900,000.
- a. Calculate the cost of a chase strategy.
- b. Calculate the cost of a level strategy.
- c. Using the Excel template, simulate several other strategies.
- d. Determine the effect on the chase strategy, in part a, of changing the hiring cost to $ 1500, $2000, and $2500. What do these changes suggest the relationship is between hiring cost and total cost?
- e. Use the Excel template to study the effect of demand changes on the total cost of the chase strategy. Assume various percentage increases and decreases in demand (110 percent, 120 percent, 210 percent, 220 percent, etc.).

Each worker can produce 900 products per month and is paid $1500 per month. Assume that at the end of last year, the company has 100 employees working on the production line. Hiring and layoff (firing) decisions are made at the beginning of each month, and associated costs are charged at that time. It costs the company $400 to hire and $800 to lay off a worker.
The company incurs holding cost for the amount of ending inventory in each month, and incurs backorder cost at the end of each month for any unfilled orders. The company incurs $2 per month for holding one unit in inventory and $4 per unit backorder.

- Scenario 4 Sharon Gillespie, a new buyer at Visionex, Inc., was reviewing quotations for a tooling contract submitted by four suppliers. She was evaluating the quotes based on price, target quality levels, and delivery lead time promises. As she was working, her manager, Dave Cox, entered her office. He asked how everything was progressing and if she needed any help. She mentioned she was reviewing quotations from suppliers for a tooling contract. Dave asked who the interested suppliers were and if she had made a decision. Sharon indicated that one supplier, Apex, appeared to fit exactly the requirements Visionex had specified in the proposal. Dave told her to keep up the good work. Later that day Dave again visited Sharons office. He stated that he had done some research on the suppliers and felt that another supplier, Micron, appeared to have the best track record with Visionex. He pointed out that Sharons first choice was a new supplier to Visionex and there was some risk involved with that choice. Dave indicated that it would please him greatly if she selected Micron for the contract. The next day Sharon was having lunch with another buyer, Mark Smith. She mentioned the conversation with Dave and said she honestly felt that Apex was the best choice. When Mark asked Sharon who Dave preferred, she answered, Micron. At that point Mark rolled his eyes and shook his head. Sharon asked what the body language was all about. Mark replied, Look, I know youre new but you should know this. I heard last week that Daves brother-in-law is a new part owner of Micron. I was wondering how soon it would be before he started steering business to that company. He is not the straightest character. Sharon was shocked. After a few moments, she announced that her original choice was still the best selection. At that point Mark reminded Sharon that she was replacing a terminated buyer who did not go along with one of Daves previous preferred suppliers. Ethical decisions that affect a buyers ethical perspective usually involve the organizational environment, cultural environment, personal environment, and industry environment. Analyze this scenario using these four variables.arrow_forwardScenario 4 Sharon Gillespie, a new buyer at Visionex, Inc., was reviewing quotations for a tooling contract submitted by four suppliers.
