Assignment 1 - Process managemnt - Capacity & Productivity Problem 1: Current Process: The flowchart shown below depicts a repetitive process. Each box represents a workstation with one worker assigned to complete each task. Therefore, there are a total of five workers for the current process Task 1 Task 2 Task 3 Task 4 Task 5 3 min 2 min 4 min 6 min 3 min 1. What is the output rate (in units per hour) from the Task 4 workstation and Task 5 workstation? Task 4 Task 5 Task4 60/6-10 units per hour Task 5 60/3=20 units 16 20 per hour 2. What is the bottleneck? Task 4- highest process time lunit) 6 minuter 3. What is the cycle time of the process (in minutes per unit)? 3+2+4+6 +3= 18 minutes 4. What is the output rate (in units per hour) for the process (i.e., process capacity? 60/6 = 10 units per hour 5. What is the labour productivity (in units per labour hour) of the process? 5/10= 2 units per labor hour 6. How many units can this process produce in 4 hours? 10(4)= 40 units Proposed Process Change 1: The first proposed change retains the existing five workers completing their current tasks and then an additional worker is hired to work at the bottleneck, doubling its capacity Tack y = 60/20 -3mins 1. What is the cycle time of the process (in minutes per unit)? locao) = 2 ounits per hr 3+2+4+6=15minutes 2. What is the output rate (in units per hour) for the process i.e., process capacity)? 60/4-15 units per hour 3. What is the labour productivity in units per labour hour) of the process? 6/15 = 2/2 units per labor hour 4. What is the percent change in labour productivity between the current and the first proposed process design? loola.pa) - 25% 1 2 Proposed Process Change 2: A second proposal would hire an additional worker to join the existing five workers. Three workers would be trained and resourced to carry out jobs made up of the current Tasks 1, 2, and 3; similarly, the other three workers would each be trained and resourced to complete the work of the current Tasks 4 and 5. 60/610 bola - 30 2013 - 20 1. What is the cycle time of the process in minutes per unit)? 00/3 20 60/4=15 60/6=10 3+2+4+673= 18 min /unit 60/3 = 20 2. What is the output rate (in units per hour) for the process (i.e. process capacity)? 10 units hour per 3. What is the labour productivity (in units per labour hour) of the process? 4. What is the percent change in labour productivity between the current and the second proposed process design?
