1. The Techno Toy Company is considering producing a handheld computer “pet” that children will have to “care for” by pressing certain keys when the pet produces audio or visual signals requesting to be “fed” or “walked.” Operations managers will be developing an assembly line that will produce 500 units per 7.5-hour work shift. The tasks, task times, and precedence requirements appear in the following table.

a. Group the tasks into work stations by selecting the shortest running time from the available list at each selection, so long as that time will fit within the remaining available time at the work station.

b. Balance the line by selecting the longest task time that will fit within the available time for the work station. Is this assignment much different from part a Why or why not?
