1) Supposed the diagram below shows the precedence relationship for fabricating a certain product. The line operates eight hours per day. 0.1 min 0.7 min 1.0 min 0.5 min 0.2 min a) Which is the bottleneck? b) What is the minimum cycle time? What would the daily output be? c) What is the maximum cycle time? What would the daily output be? d) If the desired output rate is 480 units per day, what is the required cycle time of the system? 2) A job has four tasks; task times are as follows: 1 min 1 min 2 min 1min a) What is the current per hour output? b) If a parallel workstation is set up for the third task with the same task time, what would be the new output rate? 3) There is one worker for each of the following tasks: A: 20 seconds B: 10 seconds C: 30 seconds a) Which is the bottleneck and what is the current output per minute? b) If one worker is assigned to both A and B instead of one worker for each of A and B while C remains to have only one worker, what will happen to the output rate and productivity per worker per minute? c) If the only change is that C now has two workers, what will happen to the output rate and productivity per worker per minute? d) If there are two workers doing both tasks, A and B, and there are two workers doing task C, what would happen to the output rate and productivity per worker per unit? 4) What are the advantages and disadvantages of specialization from the manager's and employee's perspective? 5) Why is job training important? What repercussions can there be if there is lack of training? Provide examples. 6) How do automation and AI affect work design and customer satisfaction? 7) What are the trade-offs of using self-directed teams instead of a more conventional approach with occasional use of teams? 8) How does ergonomics relate to work life quality? 9) Explain how organizational politics can affect organizational ethics.
