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 the multifactor productivity under each system. Use units per peso cost (labor plus equipment) as the measure.

- A U.S. Postal Service supervisor is looking for ways to reduce stress in the sorting department. With the existing arrangement, stamped letters are machine-canceled and loaded into tubs with 375 letters per tub. The tubs are then pushed to postal clerks, who read and key zip codes into an automated sorting machine at the rate of 1 tub per 375 seconds. To overcome the stress caused when the stamp canceling machine outpaces the sorting clerks, a pull system is proposed. When the clerks are ready to process another tub of mail, they will pull the tub from the canceling machine area. How many tubs should circulate between the sorting clerks and the canceling machine if 90,000 letters are to be sorted during an 8-hour shift, the safety stock policy variable, α, is 0.18, and the average waiting time plus materials handling time is 25 minutes per tub?arrow_forwardThe Goodparts Company produces a component that is subsequently used in the aerospace industry. The component consists of three parts (A, B, and C) that are purchased from outside and cost 35, 30, and 10 cents per piece, respectively. Parts A and B are assembled first on assembly line 1, which produces 185 components per hour. Part C undergoes a drilling operation before being finally assembled with the output from assembly line 1. There are, in total, six drilling machines, but at present only three of them are operational. Each drilling machine drills part C at a rate of 80 parts per hour. In the final assembly, the output from assembly line 1 is assembled with the drilled part C. The final assembly line produces at a rate of 205 components per hour. At present, components are produced eight hours a day and five days a week. Management believes that if the need arises, it can add a second shift of eight hours for the assembly lines.

At the Link's Lumber operation, a batch of 100 pine logs yields 85 utility poles with 5 labor-hours required to process the entire batch. Link's Lumber is owned by Artemis Link, whose brother Devious Link is plan- ning to marry Betty Davis, owner of Northlands Pine Plantation. Artemis expects that his future sister-in-law will sell him pine logs for the same price he is paying to purchase them from other growers right now. The difference in Northlands Pine Plantation logs, however, is that they are considerably higher-quality wood than the logs he purchases from his current suppliers. If Betty agrees to sell him Northlands Pine Plantation pine logs, each batch of 100 logs can be expected to yield 100 util- ity poles, although it will take an additional 4 labor-hours per batch to process the higher-quality wood. a.
