A group technology cell is organized to produce a particular family of products. The cell consists of
Question:
The GT cell is currently used to produce four products. All products follow the same routing, which is 1 ( 2 ( 3 ( 4 ( 5 ( 1. The product mix and station times for the parts are presented in the table below:
The average transfer between stations takes 2 minutes in addition to the time spent at the workstation.
(a) Determine the bottleneck station in the GT cell and the critical value of N. Compute the overall production rate and manufacturing lead time of the cell, given that the number of parts in the system = N*. If N* is not an integer, use the integer that is closest to N*.
(b) Compute the overall production rate and manufacturing lead time of the cell, given that the number of parts in the system = N* + 10. If N* is not an integer, use the integer that is closest to N* + 10.
(c) Compute the utilizations of the six stations.
