What is a route sheet?arrow_forwardAn assembly line running at 2000 hours/year is required to meet the annual demand of 50000 units. The total work content time = 45 min and the manning level is 1. Assuming line efficiency of 0.90 and balancing efficiency of 0.80; determine: (a) the number of work station required to meet the annual demand, and (b) the number of workers required to meet the annual demand if repositioning time of 15 sec is considered in part (b).arrow_forwardSuppose your company has just found $100,000 worth of outdated inventory in an old warehouse (this is the original manufacturing cost). Your boss asks you to consider two options: (1) re-engineer the outdated parts at a cost of $30,000, and ideally resell them for $60,000, or (2) scrap them for $15,000 cash (which is certain) in a second-hand market. What advice would you give your boss? Explain in your own words and give the data that supports your answer.arrow_forward
- If the opening inventory is 400 units, demand is 900 units, and production is 700 units, what will be the ending inventory?arrow_forwardA final assembly plant for a certain automobilemodel is to have a capacity of 240,000 units annually.The plant will operate 50 wk/yr, 2 shifts/day, 5 days/wk, and 8.0 hr/shift. It will be divided into three departments: (1) body shop, (2) paint shop, (3) trim-chassis-final department. The body shop welds the car bodies using robots, and the paint shop coats the bodies. Both of these departments are highly auto-mated. Trim-chassis-final has no automation. There are 15.5 hr of direct labor content on each car in this department, where cars are moved by a continuous conveyor. Determine (a) hourly production rate ofthe plant, (b) number of workers and workstations required in trim-chassis-final if no automated stations are used, the average manning level is 2.5, balancing efficiency 1⁄4 93%, proportion uptime 1⁄495%, and a repositioning time of 0.15 min is allowedfor each worker.arrow_forward14.15 ANSWER A AND Barrow_forward
- A single model manual assembly line produces a product whose work content time = 48.9 min. The line has 24 workstations with a manning level M = 1.25. The product has a Available shift time per day = 8 hr, but downtime during the shift reduces actual production time to 7.6 hr on average. This results in an average daily production of 256 units/day. Repositioning time per worker Tr is 8% of cycle time Tc. Determine: Line efficiency, Balancing efficiency, and Repositioning time Tr.arrow_forwardA company designs and builds cruise ships for the luxury market. Which process type does it apply?

- Consider a line consisting of only one machine. This machine takes on average 4 minutes (te=4 min) to complete a job and Ca2=Ce2=1. The arrival rate of the parts to this machine is 1/8 part/minutes. Assume that there is enough space for only 5 parts between the machines (Hint: the buffer size, b, is 5.) Compute the expected CT of this production line. CT=_________arrow_forwardA small electrical appliance is to be assembled on a single model assembly line. The line will be operated 250 days/year, 15 hours/day. The work content has been divided into work elements as defined in the following Table. Also given are the element times and precedence requirements. Annual production is to be 200,000 units. Repositioning time for each worker is 0.08 min. Determine (a) average hourly production rate, (b) cycle time, and (c) theoretical minimum number of workers required to meet annual production requirements. (d) Use all the line balancing algorithm (Largest Candidate Rule, Kilbridge and Wester Method, and Ranked Positional Weights Method) to balance the line. For your solution, determine (e) balance efficiency of the line.
