Homework MGMT 370 Chapter 14 JIT and Lean Operations Name: 1. Compute and interpret the takt time for a system where the total time per shift is 480 minutes, there is one shift, and workers are given two 15-minute breaks and 45 minutes for lunch. Daily demand is 300 units. A) State the Formula: B) Calculate: C) Interpret the results: 2. Compute and interpret the takt time for a service system that intends to perform a standardized service in only one shift each day. The system will have a total time of 440 minutes for the shift, and during that time there are two 10-minute breaks and an hour for lunch. The service system must process 90 jobs each day, A) State the Formula here: B) Calculate here: C) Interpret the results: Page 1 of 3 Homework MGMT 370 Chapter 14 JIT and Lean Operations Name: 3. Create a production schedule that achieves fairly level production and produces every product model in every cycle: Model F G H K Daily Quantity 9 8 5 6 Assume the production sequence will be F-G-H-K. Use the Stevenson sequencing rule. A) State the appropriate product sequence to use: B) Determine how many times the sequence will be repeated daily. In other words, what is the number of cycles per day? Why? C) Determine and identify the base level pattern: D) Determine how many units of each model should be produced in each cycle. In other words, what is the production quantity per cycle? Page 2 of 3 Homework MGMT 370 Chapter 14 JIT and Lean Operations Name: 4.
