Bài tập môn Quản Lý Sản Xuất Example : Compute the multifactor productivity measure for each of the weeks shown for production of chocolate bars What the productivity figures suggest? Assume 40-hour weeks and an hourly wage of $12 Overhead is 1.5 times weekly labor cost Material cost is $6 per pound Week Output (Units) Workers Material (Ibs) 30000 450 33600 470 32200 460 35400 480 - Multifactor measure = Week 1: Multifactor measure = 3.03 Week 2: Multifactor measure = 2.87 Week 3: Multifactor measure = 2.77 Week 4: Multifactor measure = 2.63 - The productivity figures suggest is that the productivity of the production of the chocolate bar in a certain period of time From which shows the efficiency of the work as well as the productivity of the company Need to change the strategy works, identify the point of clogging in the system Example : An operation has a 10 percent scrap rate As a result, 72 pieces per hour are produced What is the potential increase in labor productivity that could be achieved by eliminating the scrap? Total of produce are produced per hour = =80 (pieces) Scrap = 80x10% = (pieces) - The potential increase in worker productivity can be achieved by removing scrap can increase the quality of products, given the reasonable price, increase market share on the market, reduced the rate of competition From which the company can reap bigger profits, increase the productivity of the country The increase in labor productivity also helped to stabilize the national economy, improve wages, price carefully, stable life for employees, as well as consumers Example : A property title search firm is contemplating using online software to increase its search productivity Currently an average of 40 minutes is needed to a title search The researcher cost is $2 per minute Clients are charged a fee of $400 Company A’s software would reduce the average search time by 10 minutes, at a cost of $3.50 per search Company B’s software would reduce the average search time by 12 minutes at a cost of $3.60 per search Which option would have the highest productivity in terms of revenue per dollar of input? - Partial measures = = = =2 (per 1$ input) - Company A's productivity = = =6.3 (per 1$ input) - Company B’s productivity = = =6.72 (per 1$ input) The company B’s software would have the highest productivity in terms of revenue per dollar of input *Homestyle : What are two ways that the company has increased productivity? Why did increasing the length of the ovens result in a faster output rate? - First, the company has increases productivity cutting the non-filled cookies diagonally rather than round In addition, the company recently increased the length of each oven by 25 feet, which also increased the rate of production The bigger oven, the more cookies we can be bake in it which means the faster the output rate Second, automating the ingredients lead to reduction in the waste of ingredients and help on the cut back with human error when mixing the ingredients ... result in a faster output rate? - First, the company has increases productivity cutting the non-filled cookies diagonally rather than round In addition, the company recently increased the length... price carefully, stable life for employees, as well as consumers Example : A property title search firm is contemplating using online software to increase its search productivity Currently an average... production The bigger oven, the more cookies we can be bake in it which means the faster the output rate Second, automating the ingredients lead to reduction in the waste of ingredients and help
