Operations Management
Homework 4- Chapters 13 and 14
Due October 21, 2014
You have to work in your group. Individual efforts will not be graded.
Chapter 13- Statistical Quality Control
Problems 2, 6, 7, and 9 pages 339-341 and of the 14th edition textbook ( If you do not have the 14th edition, you may use a copy of these two pages available in the pdf file on BB in the same location you found this document).
2. The cost of quality would increase in order for the supplier to do a quality check on the customer’s order before shipment.
6. The tradeoff involves a cost/precision tradeoff. This is analogous to the service level/cost tradeoff. From an economic standpoint, if the cost of defects is very high, an AQL of zero is a good thing. If defect costs are nominal, the cost of achieving near perfect quality can be negative.
7. On a separate piece of paper.
9. On a separate piece of paper.
Chapter 14- Lean Supply Chains- Review chapter 14 and answer the following questions. Briefly explain your answer to each question referencing the textbook. 1. | Lean production is an integrated set of activities designed to achieve high-volume production using minimal inventories of raw materials, work-in-process, and finished goods. True FalseLean production is an integrated set of activities designed to achieve production using minimal inventories of raw materials, work-in-process, and finished goods. | 2. | Henry Ford used JIT concepts as he streamlined his moving assembly lines to make automobiles in the early 1900s. True FalseThe moving assembly lines are a perfect example of a JIT concept. Ford designed this system to be perfectly time efficient. | 3. | Lean production requires a "push and pull" system of inventory replenishment. True FalseRather than pushing material through the system based on weekly schedules generated by production control, the entire process is converted to a pull system that is operated directly in response to customer
