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 5 workers, who together produced an average of 90 carts per hour. Workers receive $13 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 $11 per hour while output increased by 5 carts per hour. a. Compute labor productivity under each system. Use carts per worker per hour as the measure of labor productivity. (Round your answers to 3 decimal places.)
Before
carts per worker per hour
After

Consider the order delivery system of Heartha Hardware and Construction Supplies:- Customers (whether by bulk or retail) would line up in a counter where sales representatives will entertain them. It would take about 15 minutes before a customer will be entertained due to the number of customers being served by the sales representative and only about 4 sales representatives are on duty every day.- The sales representative will take down the customer’s order in the order slip with corresponding prices. On some cases, she will ask the person in-charge in the warehouse if the items are available. She then forwards the order slip to the cashier.- The cashier would sum-up again manually the order slip from the sales representative to check the accuracy of the footing of the totals as well as the prices indicated. This would take about 10 minutes, depending on the bulk of the order being placed.- The official receipt will be printed and will be given to the…

- create an exercise involving obtaining parts per hour of work. Example: (This is an example, do not answer) A factory that produces computer mice works in a quiet and regular manner since it does not sell its product to large companies, nor is its demand very variable.It produces 280 mice per month, of which 270 are conforming products. In October 2019, 23 days were worked. Its standard operating time is 7 hours a day, with a 30-minute lunch break. In addition, in the mornings the machines must be allowed to warm up for 20 minutes. The machines are operated in this manner from Monday to Friday. When they reach the production of 250 mice, they take a "break" to review the production so far. This waiting time (kanban) takes them 4 hours. Determine the total number of parts produced during the month of October 2019. Now, create another example of parts per hour of work:arrow_forwardAn airline is planning to open a satellite ticket desk in a new shopping plaza, staffed byone ticket agent. It is estimated that requests for tickets and information will average15 per hour, and requests will have a Poisson distribution. Service time is assumed to be exponentially distributed.
