optimal number of the operators working at the line
and the optimal capacity control of the human work-
force are also need to be considered, since their im-
pact on the production planning factors like process-
ing times and WIP are critical.
The implementation of the methods and tech-
niques in a framework (as depicted in Figure 1) would
result in a comprehensive production planning and
capacity management solution that provide reliable
long- and mid-term solutions for companies apply-
ing identical assembly system structures. The core
of the planning system would be the common pro-
duction database that could be fed either by the pro-
duction planners or the MES system. The database
would form the basis for the integrated optimization
models as well as for the self-building mathematical
models that can provide feasible solution for the line
assignment problem and the mid-term capacity and
production planning problems.
