During the recent years, extensive research has been done on the field ofproject scheduling. There is always uncertainty in the area of projectscheduling that causes a deviation in the real plan from the scheduled plan.One of the solutions to deal with this uncertainty is using the critical chainmethod (CCM) in project scheduling. This method which is derived from thetheory of constraints (TOC) is a new method in project control which was firstproposed by Goldartt in 1997.In this research we attempt to use the principalsof critical chain in resource-constrained project scheduling problem. The maininnovation in this research is presentation of critical chain project schedulingproblem model with consideration of feeding buffer and using float as asupplement for feeding buffer. For this matter, the project scheduling underresources constraints with critical chain approach was first written and itsreliability was evaluated using the Lingo software. In the next step thesolution algorithm of this model was developed using the genetic algorithmand finally different sample issues were investigated. The results of thisresearch show the efficiency of the presented genetic algorithm
