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.
er A product line includes 8 different product styles, each consisting of 93 components. Assume that 9 processing operations are needed to produce each component on average with each operation taking an average 1.2 min, which includes setup time and part handling time. All operations need a production machine, and currently 25 machines are dedicated to this task. The plant operates 52 hours per week, 52 weeks a year. Determine the yearly production of each style in units (round downward). 63 504
A manufacturing firm maintains one product assembly line to produce signal generators. Weekly demand for the generators is 35 units. The line operates for 7 hours per day, 5 days per week. What is the maximum production time per unit in hours required of the line to meet the demand? ans: 1hr per unit

A process currently services an average of 42 customers per day. Observations in recent weeks show that its utilization is about 90 percent, allowing for just a 10 percent capacity cushion. If demand is expected to be 60 percent of the current level in five years and management wants to have a capacity cushion of just 4 percent, what capacity requirement should be planned? The needed capacity requirement is ____________________ customers per day. (Enter your response rounded up to the next whole number.)
The Academic Computing Center has five trainers available in its computer labs to provide training sessions to students. Assume that the design capacity of the systemis 2500 students per semester and that effective capacity equals 88% of design capacity. If the number of students who actually got their orientation session is 2150, what is the utilization of the system? O 1350 students O2150 students O 88% O 86% O 90%
A business company has the following capacity per month based on the following: 30 working days per month; 1 shift operation at 8 hours per shift; 30 minutes break per shift per employee ABC company produces bicycles and has the following Capacities per process. Frame Welding: 60 bikes per hour per machine Painting: 20 bikes per hour per worker Assembly: 50 bikes per hour per worker Inspection: 100 bikes per hour per worker What can be observed from the system if the demand for the month is 5,000 bikes?
The manager of a car wash must decide whether to have one or two wash lines. One line willmean a fixed cost of RM6000 a month, and two lines will mean a fixed cost of RM11000 amonth. Each line would be able to process 15 cars an hour. Variable costs will be RM3 per car,and revenue will be RM5.95 per car. The manager projects an average demand of between 14and 18 cars an hour. Would you recommend one or two lines? The car wash is open 300 hours amonth.
