Abstract

Construction work is often performed with limited resources. The optimal dynamic allocation of resources at simulation runtime sometimes requires that non-critical tasks be held back deliberately and not be allowed to start so that resources will be available to perform more critical activities later. This is an important issue that has escaped rigorous investigation. For certain projects it may be more expedient to model work at the activity level and not the resource level and embed the routing of resources into precedence relationships. The Hanging Lake Tunneling Project is presented as an example where the estimation of tunnel advance rates for all tunneling alternatives is performed at the activity level and where the allocation of limited resources is encapsulated in tunneling plans particular to the tunneling alternative being analyzed.
