This paper extends the field of heuristic algorithms for resource constrained scheduling problems in three important areas. First, an algorithm is introduced where the role of the heuristic scheduling urgency factor is expanded from one of solely determining the order in which activities are...

An efficient approach to the problem of minimizing total construction and utility distribution network costs in a region while still meeting projected land use demands is presented. The region is modelled as a directed network with land represented by nodes and utility links by branches. When...
