A manufacturing company has a small production line dedicated to the production




Q u e s t i o n s;LO11?1;1. A manufacturing company has a small production line dedicated to the production of a;particular product. The line has four stations in serial. Inputs arrive at station 1 and the;output from station 1 becomes the input to station 2. The output from station 2 is the input;to station 3 and so on. The output from station 4 is the fi nished product. Station 1 can;process 2,700 units per month, station 2 can process 2,500/month, station 3 can process;2,300/month, and station 4 can process 2,100/month. What station sets the maximum possible;output from this system? What is that maximum output number?;4. You are in a line at the bank drive-through and 10 cars are in front of you. You estimate;that the clerk is taking about fi ve minutes per car to serve. How long do you expect to wait;in line?;10. An enterprising student has set up an internship clearinghouse for business students. Each;student who uses the service fi lls out a form and lists up to 10 companies that he or she;would like to have contacted. The clearinghouse has a choice of two methods to use for processing;the forms. The traditional method requires about 20 minutes to review the form and;arrange the information in the proper order for processing. Once this setup is done, it takes;only two minutes per company requested to complete the processing. The other alternative;uses an optical scan/retrieve system, which takes only a minute to prepare but requires fi ve;minutes per company for completing the processing. If it costs about the same amount per;minute for processing with either of the two methods, when should each be used?;11. Rockness Recycling refurbishes rundown business students. The process uses a moving;belt, which carries each student through the fi ve steps of the process in sequence. The fi ve;steps are as follows;Time Required;Step Description per Student;1 Unpack and place on belt 1.0 minute;2 Strip off bad habits 1.5 minutes;3 Scrub and clean mind 0.8 minute;4 Insert modern methods 1.0 minute;5 Polish and pack 1.2 minutes;One faculty member is assigned to each of these steps. Faculty members work a;40-hour week and rotate jobs each week. Mr. Rockness has been working on a contract;from General Eclectic, which requires delivery of 2,000 refurbished students per;week. A representative of the human resources department has just called complaining;that the company hasn?t been receiving the agreed-upon number of students. A check;of fi nished goods inventory by Mr. Rockness reveals that there is no stock left. What;is going on?;13. A local market research fi rm has just won a contract for several thousand small projects;involving data gathering and statistical analysis. In the past, the fi rm has assigned each;project to a single member of its highly trained professional staff. This person would both;gather and analyze the data. Using this approach, an experienced person can complete an;average of 10 such projects in an eight-hour day.;The fi rm?s management is thinking of assigning two people to each project in order to;allow them to specialize and become more effi cient. The process would require the data;290 section 2 MANUFACTURING AND SERVICE PROCESSES;gatherer to fi ll out a matrix on the computer, check it, and transmit it to the statistical;analysis program for the analyst to complete. Data can be gathered on one project while;the analysis is being completed on another, but the analysis must be complete before the;statistical analysis program can accept the new data. After some practice, the new process;can be completed with a standard time of 20 minutes for the data gathering and 30 minutes;for the analysis.;a. What is the production (output per hour) for each alternative? What is the productivity;(output per labor hour)?;b. How long would it take to complete 1,000 projects with each alternative? What;would be the labor content (total number of labor hours) for 1,000 projects for each;alternative?;18. I-mart is a discount optical shop that can fi ll most prescription orders in around 1 hour.;The management is analyzing the processes at the store. There currently is one person;assigned to each task below. The optometrist assigned to task B takes an hour off for;lunch and the other employees work the entire day.;Task Time;A. Greet/register the patient 2 minutes/patient;B. Optometrist conducts eye exam 25 minutes/patient;C. Frame/lenses selection 20 minutes/patient;D. Glasses made (process can run 6 pairs of;glasses at the same time) 60 minutes/patient;E. Final fi tting 5 minutes/patient;For a typical 10-hour retail day (10 a.m.?8 p.m.), the manager would like to calculate the;following;a. What is the current maximum output of the process per day (assuming every patient;requires glasses)?;b. If another person were added, where would be the logical place?;c. What effect would a mail order lab (where the glasses are made off-site and returned in;5?7 days) have on the process?
