Simulation optimisation for improving the efficiency of a production line

Simulation optimisation for improving the efficiency of a production line
Simulation optimisation for improving the efficiency of a production line

Finding the best set up for a production line is a traditional simulation problem. Here, we apply and adapt Optimal Computing Budget Allocation (OCBA), a well-known method for optimisation via simulation to find the best design for a production line. Typically OCBA is implemented in a sequential fashion with the results of one (or a small number) of replications being used to adapt suggest how the sampling should be allocated in the next step. In this paper we change that format to fit in with the typical experimental set up at Ford and instead work in five main stages. Each stage is allocated a set amount of simulation time and we use OCBA to determine how long to run the simulation for with each system configuration. The results show that using OCBA can substantially increase the efficiency of selecting the best out of a number of designs.

Abstract

Finding the best set up for a production line is a traditional simulation problem. Here, we apply and adapt Optimal Computing Budget Allocation (OCBA), a well-known method for optimisation via simulation to find the best design for a production line. Typically OCBA is implemented in a sequential fashion with the results of one (or a small number) of replications being used to adapt suggest how the sampling should be allocated in the next step. In this paper we change that format to fit in with the typical experimental set up at Ford and instead work in five main stages. Each stage is allocated a set amount of simulation time and we use OCBA to determine how long to run the simulation for with each system configuration. The results show that using OCBA can substantially increase the efficiency of selecting the best out of a number of designs.
