Résumé

We examine the production control of homogenous transfer lines with machines that are prone to failure, and consider inventory and backlog costs. Because problem complexity grows with line size, we developed a heuristic method based on the profile of the distribution of buffer capacities in moderate size lines in order to enable the optimization of long lines. A method consisting of analytical formalism, combined discrete/continuous simulation modelling, design of experiments (DOE), and response surface methodology (RSM) was used to optimize a set of transfer lines, with one parameter per machine, for up to 7 machines. We observed a profile in the parameter distribution which can be modeled using 4 parameters. Consequently, the optimization problem was reduced to 4 parameters, in turn greatly reducing the required optimization effort. An example of a 20-machine line, optimized at 130 runs, versus 5,243,090 runs that would be necessary to solve the 20-parameter problem, is presented to illustrate the usefulness of the parameterized profile.
