Problem 6-19 (Algo) The following tasks are to be performed on an assembly line: TASK SECONDS TASKS THAT MUST PRECEDE A 20 B 15 A C 15 B 32 B E 26 C 22 D 18 H 13 E, F G The workday is 7.5 hours long. Demand for completed product is 675 per day. a. Find the cycle time required to meet the desired output rate. (Round your answer to 1 decimal place.) Cycle time 40.0 seconds per unit b. What is the theoretical number of workstations required to meet the desired output rate? (Round up your answer to the next whole number.) Number of workstations 5 d. Balance the line using sequential restrictions and the longest-operating-time rule. (Leave no cells blank - be certain to enter "0" wherever required. Round your answers to 1 decimal place.) Work Station Task Idle Time A-B || D III E-F IV E V G-H 14.0 9.0 e. What is the efficiency of the line balanced as in part (d) assuming it is running at the cycle time determined in part (a)? (Round your answer to 1 decimal place.) Efficiency 80.5% f. Suppose that demand rose from 675 to 875 units per day. What would you do? (Round your answer for cycle time down to the nearest whole number.) Reduce cycle time to 31 seconds, which may require rebalancing the line. g. Suppose that demand rose from 675 to 1,200 units per day. What would you do? (Round your answer for cycle time down to the nearest whole number.) Reduce cycle time to 23 seconds, which may require rebalancing the line.
