\begin{abstract}
Time and resource management are two crucial activities within the project management framework. This paper demonstrates how resource assignment Petri net $(RAPN)$ a class of colored Petri nets, is applied effectively for modeling and scheduling of construction projects, known as a resource-constrained project scheduling (RCPSP)
