A single model manual assembly line produces a product whose work content time = 47.8 min. The line has 24 workstations with a manning level =1.25. 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 is 8% of cycle time. Determine (a) line efficiency, (b) balancing efficiency,and (c) repositioning time.

A work cell at Chris Ellis Commercial Laundryhas a workstation with two machines, and each unit producedat the station needs to be processed by both of the machines.(The same unit cannot be worked on by both machines simultaneously.) Each machine has a production capacity of 4units per hour. What is the throughput time of the work cell?
The manager of a car wash must decide whether to have one or two wash lines. One line will mean a fixed cost of $6,000 a month, and two lines will mean a fixed cost of $10,500 a month. Each line would be able to process 15 cars an hour. Variable costs will be $3 per car, and revenue will be $5.95 per car. The manager projects an average demand of between 14 and 18 cars anhour. Would you recommend one or two lines? The car wash is open 300 hours a month.

A young mechanical engineer devised two different approaches to completing aproduction task. Both methods entail the purchase of the same working space as well asother capital equipment that will only be employed for this operation.A crew of three guys costing P30.00 per hour is required for Method A. This approachwill produce 10 units per hour, two of which will be rejects. Method B requires aworkforce of two workers, each of whom costs P35.00 per hour, to produce eight unitsper hour, one of which will be rejected. Each reject costs P20.00 because direct materialis lost. If a certain total number of units is to be produced, find which method iseconomical. DO NOT USE EXCEL, SOLVE USING FORMULA
To meet holiday demand, Penny’s Pie Shop requires a pro-duction line that is capable of producing 50 pecan pies perweek, while operating only 40 hours per week. There areonly four steps required to produce a single pecan pie withrespective processing times of 5 minutes, 5 minutes, 45 min-utes, and 15 minutes.a. What should be the line’s cycle time?b. What is the smallest number of workstations Penny couldhope for in designing the line considering this cycletime?c. Suppose that Penny finds a solution that requires onlyfour stations. What would be the efficiency of this line?
Consider a production line with five stations. Station 1 can produce a unit in 9 minutes. Station 2 can produce a unit in 10 minutes.
