Order release, dispatching and resource assignment in multiple resource-constrained job shops: an assessment by simulation

In manufacturing shops in practice, machine capacity is often constrained by more than one type of resource. Yet research mainly focusses on the effects only resource that constrains capacity, e.g. labour, tooling or auxiliary constraints. response, we use simulation to assess impact order release, dispatching and assignment rules make-to-order job with multiple The wasted while a stands idle waiting for other resources increases number constraints, all three production planning control functions have little this time. Effective can however improve operational performance terms time tardiness-related measures. general, combining release rule prioritises jobs which are available at longest queue leads best performance. Most importantly, rather counterintuitively, prioritising orders fewest missing worsens both since it reduces utilisation during periods high load. Results from dual resource-constrained consequently not directly transferable complex shops.
