Dynamic Control for Resource Leveling in Project Network Planning

To meet the physical limits of construction resources, to avoid day-to-day fluctuation in resource demands, and to maintain an even flow of application for construction resources, resource leveling is needed in the construction industry. A new idea was put forward that is the classificatory criteria of the new evaluation indexes and computational method of the dynamic evaluation indexes are redefined, because the analysis of the four resource-balance evaluation indexes shows their shortages. The new ones can efficiently avoid the frequent consumption curve, the peak or trough serious resource consumption intensity, such as supply capacity exceeding the resources of the occurrence of engineering resources, thus the uses of the recourses will be kept balance. To get the deficiencies of resource leveling indicators solved, the opportunity cost of non-predictability of the resource leveling indicators are raised, which improve the description of resource leveling performance accuracy. An example is used to demonstrate the application.
