In today's job shop, computers make information readily available, but
there is limited research about which information to use and how to u
se it controlling a dual resource constrained (DRC) job shop. We devel
op and test new order review/release (ORR) job dispatching and labour
assignment rules that use different types of information. We compare t
he performance of a naive ORR rule (i.e., releasing all jobs immediate
ly upon receipt) and other rules in the literature which use little in
formation to a new ORR rule, modified load conversion (MLC), which use
s all the available information. Our tests demonstrate that MLC perfor
ms better than the other ORR rules we tested. But the new job dispatch
ing and labour assignment rules developed to use different types of in
formation do not significantly improve performance. A sensitivity anal
ysis demonstrates that although the shop performance is sensitive to t
he cost structure for every policy tested, the new MLC ORR rule perfor
ms well over a wide range of cost structures.
