3. Dell Computer's primary consumer business takes orders from customers for specific configurations of desktop and laptop computers. Customers must select from a certain model line of computer and choose from available parts, but within those constraints may customize the computer as they desire. Once the order is received, Dell assembles the computer as ordered and delivers it to the customer. What type of manufacturing process is described here?5. You are in a line at the bank drivethrough and 10 cars are in front of you. You estimate that the clerk is serving i can about every ve minutes. How long do you expect to wait in line? 16. The desired daily output for an assembly line is 360 units. This assembly line will operate 450 minutes per day. The following table contains information on this product's task times and precedence relationships: TASK TASK TIME (SECONDS) IMMEDIATE PREDECESSOR 30 35 A 30 35 B 15 C 65 C 40 E, F 25 D, G a. Draw the precedence diagram. b. What is the workstation cycle time required to produce 360 units per day? c. Balance this line using the largest number of following tasks. Use the longest task time as a secondary criterion. d. What is the efficiency of your line balance, assuming it is running at the cycle time 17 from part (b)? 17. Some tasks and the order in which they must be performed according to their assembly requirements are shown in the following table. These are to be combined into workstations to create an assembly line. The assembly line operates 71/2 hours per day. The output requirement is 1,000 units per day. TASK PRECEDING TASKS TIME (SECONDS) 15 24 6 12 18 FXL- IQTMDOOR 11a. What is the workstation cycle time required to produce 1,000 units per day? b. Balance the line using the longest task time based on the 1,000-unit forecast, stating which tasks would be done in each workstation. C. For part (b), what is the efficiency of your line balance, assuming it is running at the cycle time from part (a)? d. After production was started, Marketing realized that it understated demand and must increase output to 1,100 units. What action would you take? Be specific and quantitative in your answer. 18. An assembly line is to be designed to operate 712 hours per day and supply a steady demand of 300 units per day. Here are the tasks and their performance times: PRECEDING PERFORMANCE PRECEDING PERFORMANCE TASK TASKS TIME (SECONDS) TASK TASKS TIME (SECONDS) 70 G D 60 40 H E 50 45 I E 15 A 10 L G 25 B 30 K H , I 20 20 F J , K 25 a. Draw the precedence diagram. b. What is the workstation cycle time required to produce 300 units per day? c. What is the theoretical minimum number of workstations? d. Assign tasks to workstations using the longest operating time. e. What is the efficiency of your line balance, assuming it is running at the cycle time from part (b)? f. Suppose demand increases by 10 percent. How would you react to this? Assume that you can operate only 712 hours per day
