Identifying the critical sequence in a resource constrained project

Abstract

Limited resources invalidate the critical path as the set of activities serving as the focus of the scheduling process thus determining project duration. The critical sequence, defined as the set of activities which are connected by technology and/or resource sharing, is suggested as an alternative to the critical path. Problems created by the use of the critical path concept for scheduling individual activities are demonstated. An algorithm, based on existing computer software, is suggested for identifying the critical sequence.
