上游充通大学 Resource-constrained Planning SHANGHAI JIAO TONG UNIVERSITY One way to consider resources is to taken them into account when drawing the logical relationships among activities in the network diagram. At a minimum,network diagrams illustrate the technical constraints among activities. Paint Living Room Start Project Paint Kitchen Finish Project Paint Bedroom
