A recurring maintenance job in a factory is being done by a three-man crew. Due to the nature of the job and space limitations, it was observed that two of the men were idle 37% of the time; one of the men was also idle an additional of the time, and at any given time only one man was required. The men were each paid P24.00 per hour. Each time the job was performed a set of tools and equipment with a value equivalent to P36.00 per hour was used. If the three-men crew could complete the work in 5 hours, which crew size would be the most economical

A company that makes shopping carts for supermarkets and other stores recently purchased somenew equipment that reduces the labor content of the jobs needed to produce the shopping carts.Prior to buying the new equipment, the company used five workers, who produced an average of80 carts per hour. Workers receive $10 per hour, and machine cost was $40 per hour. With the newequipment, it was possible to transfer one of the workers to another department, and equipment costincreased by $10 per hour while output increased by four carts per hour.a. Compute labor productivity under each system. Use carts per worker per hour as the measure oflabor productivity.

.A team of 10 unloaders is employed in good reception bay of a large warehouse. During an 8 hour day 40 lorries arrive and it takes the team 10 minutes to unload each lorry. Each team member is paid RM3 per hour and it costs RM10 per hour to keep lorries waiting. Studies show that increasing the team to 14 men would reduce the unloading time to 7 minutes. Would it be worthwhile increasing the team to 14?

1. A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used five workers, who produced an average of 100 carts per hour. Workers receive $20 per hour, and machine cost was $50 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $10 per hour while output increased by four carts per hour. a. Compute labor productivity under each system. Use carts per worker per hour as the measure of labor productivity. b. Compute the multifactor productivity under each system. Use carts per dollar cost (labor plus equipment) as the measure. Comment on the changes in productivity according to the two measures, and on which one you believe is the more pertinent for this situation. C.

A company that makes a product recently purchased some new equipment that reduces the labor content of the jobs needed to produce the product. Prior to buying the new equipment, the company used six workers, who produced an average of 90 units per hour. Workers receive P35 per hour and machine cost was P2,000 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by P500 per hour while output increased by four units per hour. Compute labor productivity under each system. Use units per worker per hour as the measure of labor productivity.

For the production of part R-193, two operations are being considered. The capital investment associated with each operation is identical. Operation 1 produces 2,100 parts per hour. After each hour, the tooling must be adjusted by the machine operator. This adjustment takes 15 minutes. The machine operator for Operation 1 is paid $24 per hour (this includes fringe benefits). Operation 2 produces 2,350 parts per hour, but the tooling needs to be adjusted by the operator only once every two hours. This adjustment takes 45 minutes. The machine operator for Operation 2 is paid $13 per hour (this includes fringe benefits). Assume an 8-hour workday. Further assume that all parts produced can be sold for $0.35 each. a. Should Operation 1 or Operation 2 be recommended? b. What is the basic tradeoff in this problem?
A machine shop manufactures two types of bolts. The bolts require time on each of the three groups of machines, but the time required on each group differs, as shown in the table below. Type I Type IIMachine 1 0.2 min 0.2 minMachine 2 0.6 min 0.2 minMachine 3 0.04 min. 0.08 min Production schedules are made up one day at a time. In a day, 300, 720, and 100 minutes are available, respectively, on these machines. Type I bolts sell for 15¢ and type II bolts for 20¢. (a) How many of each type of bolt should be manufactured per day to maximize revenue?(b) What is the maximum revenue?(c) Suppose the selling price of type I bolts began to increase. Beyond what amount would this price have to increase before a different number of each type of bolts should be produced to maximize revenue?
PLEASE ANSWER URGENTLY AND SHOW ALL CALCULATIONS QUESTION It takes a cycle of 12 minutes to mould 50 defect-free standard bricks plus 1 minute to adjust the machine for a brick-making machine operated by two machine operators paid R70/hr each. Another lower-capacity machine also takes 12 minutes to mould the bricks plus 36 seconds to adjust the machine, to produce 25 standard bricks operated by one operator paid R100 per hour. If both machines are operated 8 hours a day and a standard brick is sold at R2.00, determine which process should be selected?
