Stanford Rosenberg Computing wants to establish an assembly line for producing a new product, the Personal Digital Assistant (PDA). The tasks, task times, and immediate predecessors for the tasks are as follows:
|Task||Time (sec)||Immediate Predecessors|
a) What is the cycle time?
b) What is the theoretical minimum for the number of workstations that Rosenberg can achieve in this assembly line?
c) Can the theoretical minimum actually be reached when workstations
Sue Helms Appliances wants to establish an assembly line to manufacture its new product, the Micro Popcorn Popper. The goal is to produce five poppers per hour. The tasks, task times, and immediate predecessors for producing one Micro Popcorn Popper are as follows:
|Task||Time (min)||Immediate Predecessors|
a) What is the theoretical minimum for the smallest number of workstations that Helms can achieve in this assembly line?
b) Graph the assembly line and assign workers to workstations. Can you assign them with the theoretical minimum?
c) What is the efficiency of your assignment?
The following table details the tasks required for Indiana-based Frank Pianki Industries to manufacture a fully portable industrial vacuum cleaner. The times in the table are in minutes. Demand forecasts indicate a time of 10 minutes.need to operate with a cycle
|ACTIVITY||ACTIVITY DESCRIPTION||IMMEDIATE PREDECESSORS||TIME|
|A||Attach wheels to tub||–||5|
|B||Attach motor to lid||–||1.5|
|C||Attach battery pack||B||3|
|D||Attach safety cutoff||C||4|
|F||Attach lid to tub||A, E||2|
|H||Function test||D, F, G||3.5|
a) Draw the appropriate precedence diagram for this production line.
b) Assign tasks to workstations and determine how much idle time is present each cycle.
c) Discuss how this balance could be improved to 100%.
d) What is the theoretical minimum number of workstations?
