3.3 How does an automated assembly operate with a minimum of manual labor involvement?How is data collected and recorded during an automated manufacturing process?
A product whose total work content time = 50 minutes is to be assembled on a manual production line. The required production rate is 30 units per hour. From previous experience with similar products, it is estimated that the manning level will be close to 1.5. Assume E = Eb = 1.0. If 9 seconds will be lost from the cycle time for repositioning, determine:
The cycle time, and
How many workers and
Stations will be needed on the line.
An 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).

- A 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_forwardElaborate with examples, The Importance of Machines in human Life.arrow_forwardA company designs and builds cruise ships for the luxury market.

- There are four distinct categories that can be used to classify production systems. A concise explanation and example are provided for each of these categories in turn.arrow_forwardSuppose your company has just found $100,000 worth of outdated inventory in an old warehouse (this is the original manufacturing cost). Your boss asks you to consider two options: (1) re-engineer the outdated parts at a cost of $30,000, and ideally resell them for $60,000, or (2) scrap them for $15,000 cash (which is certain) in a second-hand market.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_forwardIn a factory where there are three shifts: The machine overhead cost is found to be £8.20 / hr, the labour overhead cost is found to be £30.20/hr, and the premises overhead cost is found to be £3.50/hr. Using the principle of overhead costing: If a single component takes 23 minutes to manufacture on the milling machine. What is the cost / part? You should include machine costs, labour costs and premises costs in your answer, but you can neglect material and energy costs. Express your answer in £ rounded up to the nearest penny.arrow_forward
- What exactly do you mean by a production system?arrow_forward(a) There are several reasons why a certain manufacturing process is selected. Explain how time-scale allowed for design and manufacture can influence selection of a manufacturing process. Give one example. (b) Explain how flexibility in production can become an important manufacturing process requirement.
