- 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.)arrow_forwardScenario C: Suppose you are given the process flowchart shown below. There are no buffers between tasks. Task 1 and 2 produce "Part A", and Task 3 and 4 produce "Part B"; Task 5 assembles each unit of a finished product by combining one unit of "Part A" with one unit of "Part B". Using this, answer the next 3 questions: Tpt Cap. = 10 units/hour- Tpt Cap. = 15 units/hour Task 1 5 ● 8 10 15 20 Task 3 Tpt Cap. = 5 units/hour Task 2 Tpt Cap. = 8 units/hour Task 4 Tpt Cap. = 20 units/hour Task 5 In this scenario, how many units would Task 5 actually produce each hour? Pick the closest answer.

- (Atlas Inc.) Atlas Inc. is a toy bicycle manufacturing company producing a five-inch small version of the bike that Lance Armstrong rode to win his first Tour de France. The assembly line at Atlas Inc. consists of seven work stations, each performing a single step. Stations and processing times are summarized here: Step 1 (30 sec.): The plastic tube for the frame is cut to size. Step 2 (20 sec.): The tube is put together. Step 3 (35 sec.): The frame is glued together Step 4 (25 sec.): The frame is cleaned. Step 5 (30 sec.): Paint is sprayed onto the frame. Step 6 (45 sec.): Wheels are assembled. Step 7 (40 sec.): All other parts are assembled to the frame. Under the current process layout, workers are allocated to the stations as shown here: Worker 1: Steps 1, 2 Worker 2: Steps 3, 4 Worker 3: Step 5 Worker 4: Step 6 Worker 5: Step 7 a.
