Problem 1 Max Products is setting up an assembly line to produce
radio dog collars. The line will run 12 hours a day, and
will need to produce 400 collars a day. The various
tasks, along with their required times and immediate
predecessors, are shown below.

Problem 2 Suppose that management ignores the takt time and minimum
workstation calculations in Problem 1, and decides to set
up four workstations, as follows:
Workstation 1: Activities A and C
Workstation 2: Activities B, D, E, G and H
In the space below, calculate the cycle time for this line, as well as the idle time
and percent idle time.
