A paced assembly line has been devised to manufacture calculators, as the following data show: Station Work ElementAssigned Work ElementTime (min) S1 S2 S3 S4 S5 S6 A D,E C B,F,G H,I,J K 2.7 0.6, 0.9 3.0 0.7, 0.7, 0.9 0.7, 0.3, 1.2 2.4 a. What is the maximum hourly output rate from this line? (Hint: The line can go only as fast as its slowest workstation.)b. What cycle time corresponds to this maximum output rate?c. If a worker is at each station and the line operates at this maximum output rate, how much idle time is lost during each 10-hour shift?d. What is the line’s efficiency?
An assembly line is to be designed to operate 13 hours per day and supply a steady demand of 325 units per day. Here are the tasks and their performance times: TASK PRECEDINGTASKS PERFORMANCE TIME (SECONDS) TASK PRECEDINGTASKS PERFORMANCETIME (SECONDS) a — 48 g d 43 b — 58 h e 38 c — 73 i f 23 d a 63 j g 33 e b 88 k h, i 53 f c 23 l j, k 67 A) What is the efficiency of your line balance? B) Suppose demand increases by 10 percent. How would you react to this? Assume that you can operate only 13 hours per day in regular time. (Round your answers to the nearest whole number.)
SITUATION: A company is about to begin production of a new product. The manager of the department that will produce one of the components for the product wants to know how often the machine used to produce the item will be available for other work. The machine will produce the item at a rate of 200 units a day. Eighty units will be used daily in assembling the final product. Assembly will take place five days a week, 50 weeks a year. The manager estimates that it will take almost a full day to get the machine ready for a production run, at the cost of $300. Inventory holding costs will be $10 a year. QUESTION: Suppose the manager decides to increase the run size of the new product. How many additional units would be needed just to accommodate the other job? How much will that increase the total annual cost?
