Question
Chapter 10, Problem 28P
a
Summary Introduction
Interpretation:
Run time of batches of wooden slates.
Concept Introduction: Materials Requirement Planning is a process in which planning is made for the requirement of raw material required for manufacturing of the finished product.
a
Expert Solution
Explanation of Solution
Number of units demanded = 14,600 per year
Production rate per day = 160 units
Daily demand of units = 40 units.
Run time is calculated by dividing the demand and the production rate.
Hence, the run time for one setup is 18.25 days per setup.
b
Summary Introduction
Interpretation:
Run size of batches of wooden slates.
Concept Introduction: Materials Requirement Planning is a process in which planning is made for the requirement of raw material required for manufacturing of the finished product.
b
Expert Solution
Explanation of Solution
Run size is calculated by multiplying the run time and the production rate per day.
Hence, the run time for one set up is 2,920 units per setup.
c
Summary Introduction
Interpretation:
Maximum number of wooden slates o be used for wooden crates.
Concept Introduction: The efficiency of output is the actual productivity generated compared with the planned or effective capacity. It is usually calculated by dividing actual output by effective capacity.
c
Expert Solution
Explanation of Solution
Maximum inventory is calculated by subtracting the number of units per setup from the run size.
Number of units per setup is calculated by multiplying the number of days per setup and the daily demand.
Maximum inventory is calculated by subtracting the number of units per setup from the run size.
Hence, the maximum inventory is 2,190 units.

- You are the president of XYZ Manufacturing company. You have recently learned about the following issue: A month ago, the company’s general manager (GM) told one of the line managers to produce an extra 15,000 units of a product so that there would be inventory in stock for the next time the item is ordered. Last week, the GM scolded the line manager for having 15,000 units of the item in stock. The GM told the line manager that producing excess inventory costs the company money and should never be done. The GM then puts the line manager on a performance plan. This is not the first time you have heard about the GM telling an employee to do one thing only to criticize him or her for doing it later. This employee feels very frustrated by this, but does not want to make a formal complaint because she has seen other employees lose their jobs or get demoted for questioning the GM.

The outline should address the following:…arrow_forwardA toy manufacturer uses 51,920 rubber wheels per year for its popular dump truck series.

- A company manufactures hair dryers. It buys some of the components, but it makes the heating elements, which it can produce at the rate of 800 per day. Hair dryers are assembled daily, 250 days a year, at a rate of 300 per day. Because of the disparity between the production and usage rates, the heating elements are periodically produced in batches of 2,000 units. Approximately how many batches of heating elements are produced annually? If production on a batch begins when there is no inventory of heating elements on hand, how much inventory will be on hand two days later? The same equipment that is used to make the heating elements could also be used to make a component for another of the firm’s products. That job would require four days, including setup. Setup time for making a batch of heating elements is a half day. Is there enough time to do this job between productions of batches of heating elements?

A lab orders a number of chemicals from the same supplier every 30 days. Lead time is five days.The assistant manager of the lab must determine how much of one of these chemicals to order. Acheck of stock revealed that eleven 25-milliliter (ml) jars are on hand. Daily usage of the chemical isapproximately normal with a mean of 15.2 ml per day and a standard deviation of 1.6 ml per day. Thedesired service level for this chemical is 95 percent.a. How many jars of the chemical should be ordered?b. What is the average amount of safety stock of the chemical?arrow_forwardYou run a food bar in UCLA Ackerman, and you sell chocolate croissants for breakfast. Your daily demand for chocolate croissants is on average 50, with a standard deviation of 8. The unit cost of a croissant is $0.70, and you sell at a unit price of $3.00. The refrigerated chocolate croissant must be consumed within 7days (one week) after purchased from your supplier, so you dispose leftover inventory and purchase fresh croissants once every week. Assume the demand in each of the seven days is independently distributed. (The z-table for normal distribution is attached.) (a) What is the optimal weekly purchase quantity for the chocolate croissant? What is average inventory? A student leader, Mark, came to you one day and told you that Anderson School would hold a special event next Thursday morning, and there would be additional demand for the chocolate croissant on that day. Mark wants to reserve a certain amount of croissant from you and sell in the special event at the regular price.…arrow_forward
