What cycle time to mult te the desired What is the theoretical minimum number of d. Use the longest work element decision rule to bol ance the line and calculate the efficiency of your solution Use the most followers work element decision rule to balance the line and calculate the efficiency of your solution 17. Refer back to Problem 16. Suppose that in addition to the usual precedence constraints, there are two tonin constraints within the trim line. First, work elements Kand L should be assigned to the same station: both use a common component, and assigning them to the same station conserves storage space. Second, work elements and cannot be performed at the same station a. Using trial and error, balance the line as best B A 30 A D 20 E 4 B B 15 F G 10 C you can H 8 1 12 DE FO HD 20 Total 160 b. What is the officiency of your solution? 18. To meet holiday demand, Penny's Pie Shop requires production line that is capable of producing 50 peca pies per week, while operating only 40 hours per we There are only four steps required to produce a sing pecan ple with respective processing times of 5 min 5 minutes, 45 minutes and 15 minutes. a. What should be the line's cycle time? b. What is the smallest number of workstations Po could hope for in designing the line considerin cycle time? 16. The trim line at PW is a small subassembly line with other such lines, feeds into the final chassis The entire assembly line, which consists of more than itself involves only 13 work elements and must had workstations, is to make PW's now E cars. The time curs per hour. Work-oloment data are as follows: Work Element Time (Sec) 24 B 0.5 None 2.1 c. Suppose that Penny finds a solution that requi only four stations.
