3. Consider a machining work cell consisting of 2 machines and 1 worker. The machines need to be adjusted before they can be used to produce a unit. The setup times and the operation times of the machines are given in the following table. Workstation Processing time per unit (in secgnds) 100 90 Setup Time (in seconds) 20 10 Suppose the total walk time of the worker is 60 seconds. The total task time of the worker is 80 seconds. What is the cycdle time (in seconds) of the cell? Please provide at least one step of calculation and the correct answer for full credit. (4 points)

Explanation / Answer

Cycle time = (Set up time of machine A + operations time of machine A) + Walk time + ( Set up time of machine B + Operational time of machine B)

=(20+100) +60 + ( 10+90)

= 280 sec.

Worker's task time is assumed to coincide with that of machines' opeerations time
