Construction Schedule Management Using ResourceConstrained Project Scheduling Model

Abstract:

Combining the study of resourceconstrained projectscheduling problem with the demand of construction schedule management in real projects, this paper integrates a hybrid algorithm with generalized precedence relations (GPRs) scheduling model, and then proposes better solutions for resourceconstrained schedule management. The hybrid algorithm presents crossover and mutation operations from differential evolution (DE) with artificial bee colony (ABC) to balance exploration and exploitation phases of the optimization process. Furthermore, the proposed model applies a serial method with generalized precedence relations to reflect individualvector priorities into the task schedule to calculate project duration. In order to generalize the use of most realworld construction projects, the resourceconstrained schedule management contains some methods by calculating critical paths, applying resource leveling of noncritical tasks, using correlation analysis to tradeoffs between time and cost of critical tasks. In the eclipse environment of Java programming language, it could obtain stable and accurate results, which project managers may use to make optimal decisions by resource constrained schedule, resource allocation, the optimized schemes of resources and duration.
