In this paper, the assembly line balancing problem when ergonomics principles are taken into account is considered. Two different approaches are presented and discussed with a numerical example to provide new insights on the field and to illustrate their use on a didactic example. The first one applies a multi-objective model based on the energy expenditure, used to estimate the ergonomics leve...

Hybrid analytic and simulation models are used in solving complex problems in a variety of domains, but are less commonly used in production system design. This paper reviews hybrid approaches and their applications, proposes a new hybrid modeling class, and illustrates a cost function for selecting analytic or simulation modeling approaches via a problem solving process. To illustrate the new ...

A chance-constraint multi-objective model under uncertainty in the availability of subassemblies is proposed for scheduling in ATO systems. The on-time delivery of customer orders as well as reducing the company's cost is crucial; therefore, a three-objective model is proposed including the minimization of1) overtime, idletime, change-over, and setup costs, 2) total dispersion of items’ deliver...
