A process improvement team is working to improve the production output at the Johnson Manufacturing plant’sHeader Cell that manufactures a key component, headers, used in commercial air conditioners. A header is partof the circulatory system of a commercial air conditioner that moves coolant between various components suchas the evaporator coil and the condenser coil. Currently, the header production cell is scheduled separately fromthe main work in the plant. Often, individual headers are not sequenced to match the product they go into on thefinal assembly line in a timely fashion, and so the product can sit in queue waiting for a header
Because of its labor contract, a company must hire enough labor for 100 units ofproduction per week on one shift or 200 units per week on two shifts. It cannot hire,lay off, or assign overtime. During the fourth week, workers will be available fromanother department to work part or all of an extra shift (up to 100 units). There is aplanned shutdown for maintenance in the second week, which will cut production tohalf. Develop a production plan. The opening inventory is 200 units, and the desiredending inventory is 300 units
Consider a law firm with 15 lawyers and 3 paralegals. The firm is struggling to keep up with the high demand for its services, particularly during the busy litigation seasons. It has been observed that the lawyers spend a significant amount of their time on administrative tasks that could potentially be handled by paralegals. After a careful study of the work distribution within the firm, it was determined that 35% of the activities carried out by the lawyers are administrative in nature. Given that each lawyer works 50 hours a week, please determine:
(a) How many additional paralegals should the firm hire to handle the administrative tasks currently performed by the lawyers?
(b) If the lawyers' time spent on administrative tasks is redirected to billable legal work, by what percentage could the firm potentially increase its billable hours?

- 4. The Spencer Optics Company produces an inexpensive line of sunglasses. The manufacturing process consists of assembling two plastic lenses (produced by the firm's plastic molding depart- ment) into a finished frame (purchased from an outside supplier). The company is interested in using material requirements planning to schedule its operations and has asked you to prepare an example to illustrate the technique. The firm's sales manager has prepared a 10-week sales forecast for one of the more popular sunglasses (the Classic model) for your example. The forecast is 100 units per week. Spencer has customer orders of 110 units, 80 units, 50 units, and 20 units in weeks 1, 2, 3, and 4, respectively. The sunglasses are assembled in batches of 300 units. Presently, three such batches are sched- uled: one in week 2, one in week 5, and one in week 8.

Batch setup times are negligible. The flowchart denotes the path each product follows through the manufacturing process, and each product’s price, demand per week, and processing times per unit are indicated as well. Purchased parts and raw materials consumed during production are represented by inverted triangles. EU can make and sell up to the limit of its demand per week; no penalties are incurred for not being able to meet all the demand. Each workstation is staffed by a worker who is dedicated to work on that workstation alone and is paid $6 per hour for an entire week, regardless of how much the worker is used. Total labor costs per week are fixed. Variable overhead costs are $1,500/week. The plant operates one 8-hour shift per day, or 40 hours/week.
