Chapter 9, Problem 38AP
Summary Introduction
Interpretation: The order in which shoes are to be repaired for the minimizations of the total make span for the given jobs is to be determined.
Concept Introduction:
Lateness of process is defined as the length of time which is past its deadline that it is finished already. In this L’s Algorithm is used to determine the sequence for the minimization of maximum lateness. This algorithm schedules the arriving task simultaneously on one processor by using precedence constraints.

You are a newly hired manager of Automotive Company. Since it is part of a manufacturing industry, the company operates day and night. During your first few weeks with the company, you have noticed a problem area in the shifting schedule of the employees. You have observed that changing from one shift to another creates long periods of low or stopped production which became a costly and destructive routine. Also, you have noticed that the manufacturing process of Automotive Company is longer compared to your previous car manufacturing company since the placement of the inputs for car production is relatively far from the actual production units.
QUESTION 1: What type/s of waste that Lean Approach targets to eliminate is/are present in the case?
QUESTION 2: What is the most effective Lean approach tool/technique that should be employed to resolve the problem areas in the Automotive Company?
An enterprising student has set up an internship clearinghouse for business students. Each student who uses the service fills out a form and lists up to 10 companies that he or she would like to have contacted. The clearinghouse has a choice of two methods to use for processing the forms. The traditional method requires about 20 minutes to reviewthe form and arrange the information in the proper order for processing. Once this setup is done, it takes only two minutes per company requested to complete the processing. The other alternative uses an optical scan/retrieve system, which takes only a minute to prepare but requires five minutes per company for completing the processing. If it costsabout the same amount per minute for processing with either of the two methods, when should each be used? (Answer in Appendix D)

- Cubway, the sandwich shop, is run by Jim, Tim and Kim. When a customer arrives, Jim spends 5 minutes taking order from the customer. After this, Tim prepares bread and Kim prepares filling for the order. These activities are performed in parallel, and take 6 and 12 minutes respectively. Jim then assembles the bread and filling, which takes 4 minutes of his time. Finally, Tim spends 1 minutes in delivering the order and taking payment. What is maximum number of sandwiches Cubway can make per hour?

His work crew is comprised of unskilled workers who load large transport trucks with bags of cement, gravel and sand. The work is hard and the employee turnover rate is high. Employees record their attendance on separate timecards. Sassy Ko authorizes payroll payments each week by signing the timecards and submitting them to the payroll department. The paychecks are then prepared by payroll and distributed to Sassy KO, who distributes them to his work crew. a) Identify any control problems in the system. b) What sorts of frauds are possible in this system?

The part is moderately complex and the volume of the part is about 10 cubic centimeters. Assume that the part is designed for injection molding and can be made with a two part mold. The company needs to make 250,000 parts made from ABS plastic. Once the mold is made it will take a worker 1 minute to make one part using the injection molding machine. The company will use contract manufacturing to produce the parts. Estimate the cost per part and explain how you came up with the number. (If you are stuck look at the Contract Manufacturing Cost per Unit section. Also keep in mind that there is no exact right answer, the goal is to come up with a reasonable estimate.) Contract Manufacturing Cost per Unit: It’s not uncommon to hire another company to perform some or all the manufacturing for a product. To estimate the cost use ((Cost of Parts and Materials) + (man hours) × $40)/.75arrow_forward
- local market research fim has just won a contract for several thousand small projects involving data gathering and statistical analysis. In the past, the firm has assigned each project to a single member of its highly trained professional staff. This person would both gather and analyze the data Using this approach, an experienced person can complete an average of 10 such projects in an eight-hour day. The firm's management is thinking of assigning two people to each project in order to allow them to specialize and become more efficient The process would require the data gatherer to fill out a matrix on the computer, check it and transmit it to the statistical analysis program for the analyst to complete. Data can be gathered on one project while the analysis is being completed on another, but the analysis must be complete before the statistical analysis program can accept the new data.
