Assignment Flexibility in a Cellular Manufacturing System - Machine Pooling versus Labor Chaining -
نویسندگان
چکیده
In this paper, we compare the effects of machine pooling and labor chaining by means of a simulation study. In this study, the independent variables are: (1) the level of machine pooling (no. of jobs that can be produced in more than one cell), (2) the level of labor chaining (no. of workers able to work in more than one cell), and (3) labor utilization/machine utilization. The dependent variable is the mean flow time of jobs. Major outcome of our study is that, within our simulation setting, machine pooling is more important than labor chaining. All interaction effects, however, appear to be significant. As a consequence of our study, we suggest that managers should support the development of procedures for inter-cell movements of jobs. If there is a certain level of routing flexibility over cells, it is in most CM environments not needed to support the possibility of moving workers from one cell to another cell.
