1) Below is the list of task elements which are required in a manufacturing process of a small electrical appliance. Annual demand for this appliance is 100,000 units. The manufacturing line will operate with 96% efficiency for 50 weeks in a year, 5 shifts per week, and 7.5 hours per shift. Task 1 Task Time (min) Precedence 0.2 0.4 0.7 0.1 Description Place frame on work holder and clamp Assemble plug, grommet to power cord Assemble brackets to frame Wire power cord to motor Wire power cord to switch Assemble mechanism plate to bracket Assemble blade to bracket Assemble motor to bracket Align blade and attach to motor Assemble switch to motor bracket Attach cover, inspect, and test Place in tote pan for packing 0.11 0.32 0.6 6,7,8 5,8 10 11 12 0.27 0.38 0.5 0.12 9, 10 11 Determine the following: a) Total work content time. b) Required hourly production rate to achieve the annual demand. c) Cycle time. d) Theoretical minimum number of workers required on the line. e) Precedence diagram. If the planned cycle time is 1 min: f) Use the largest candidate rule and show all your work to estimate the number of workstations. g) Use ranked positional weights method and show all your work to estimate the number of workstations. h) Calculate the efficiency of lines for both methods. Which method finds a more efficient design? i) What should be the minimum planned cycle time if the manufacturer has to have at most 4 workstations and how should the assignments of task elements be in this case
