Multiple Resource Leveling in Construction Systems through Variation of Activity Intensities.

The resource leveling problem for a construction system producing a stream of output units is considered. The system is modeled using a critical-path-analysis activity network, from which an extended network is developed for an integrated planning effort of all output units. Activity intensity variables are defined which measure activity demand rates for resources and consequent activity durations for the production of each output unit. A heuristic approach consisting of an iterative non-linear programming procedure is presented which computes activity durations intensities for the minimization of resource capacity costs subject to meeting construction due dates. The application of a major ship overhaul is described, in which the procedure was used to level workloads of the various labor-trade shops. Author
