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.

. Sarah’s Organic Soap Company makes four kinds of organic liquid soap: “regular,”“lavender,” “citrus,” and “tea tree.” Demands for the four scents are 150, 120, 75, and50 kgs per hour, respectively. Sarah’s production process can produce any soap at therate of 450 kgs per hour, but 1.5 hours are needed to switch between scents. Duringthose switchover times, the process doesn’t produce any soap. Sarah wants to choosea production schedule that (i) cycles repeatedly through the four scents, (ii) meets therequired demand, and (iii) minimizes the amount of inventory held.How many kgs of “regular” should Sarah produce before switching over to another scent?

A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 20-minute setup. Once in production, the PCB machine requires only 0.15 minute per board. Assume there is ample demand.
Say the PCB machine produces 200 boards between setups and demand is 2 boards per minute. Given this operating process, what is the average inventory of boards at the PCB machine?

- A finished goods inventory on average contains 10,000 units. Demand averages 1,500 units per week. Given that the process runs 50 weeks a year, what is the expected inventory turn for the inventory? Assume that each item held in inventory is valued at about the same amount.arrow_forwardA company wants to produce 10,00 units of an item over the next three months at a uniform rate. Because of an annual shutdown in the third month, the first month has 15 working days; the second, 18 working days; and the third, 10 working days. On the average, how much should the company produce each day to level production?arrow_forwardCompute Lead Time Jackson Fabricators Inc. machines metal parts for the automotive industry. Under the traditional manufacturing approach, the parts are machined through two processes: milling and finishing. Parts are produced in batch sizes of 80 parts. A part requires 2 minutes in milling and 6 minutes in finishing. The move time between the two operations for a complete batch is 7 minutes. Under the lean philosophy, the part is produced in a cell that includes both the milling and finishing operations. The operating time is unchanged; however, the batch size is reduced to 5 parts and the move time is eliminated. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the traditional and lean manufacturing methods. If reguired, round percentages to one decimal place.

- 30) XYZ Company The XYZ Company uses 175 handles per day. The company operates 300 days per year. It costs $2.00 to carry one handle in inventory for one year. When handle inventory is low, an order is sent to the fabrication department to manufacture more handles. Fabrication can produce handles at a rate of 1500 per day and send the handles over to assembly while production is in progress. The setup for each production run costs $500. Assume the XYZ company orders 9,000 handles at a time (not necessarily the economic order quantity). The order receipt period = _____ days.

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?

- 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. Create an outline that proposes a leadership solution to this issue. The outline should address the following:…arrow_forwardA Printed Circuit Board (PCB) machine installs integrated circuits onto a board.

Given this operating process, what is the utilization of the PCB machine? answer:________percentarrow_forwardThe Northridge Company tends to keep the inventory low. At the same time, it is important to respond to demand quickly, since a customer who wants a product K is very likely to get one from a competitor if Northridge Company doesn’t have one available immediately. Northridge Company’s current policy to produce the product K is to produce 100 per week, which is the average demand. Even this is a problem, as the production manager has pointed out, since the equipment is also used for other products and the lot size of 300 would be much more efficient. He said he is currently set up the production for product K for the next week and states that he has capacity available to produce 300 at a time next week. The following lists the forecasts and actual customer orders for the next 12 weeks.
