How Point-to-Point Relations Change Influence Lines in Schedule Networks

Abstract

Influence line diagrams depict the effect of changing the duration of a single activity on the whole project’s duration. The behaviour of influence lines, transitions between criticality types were hitherto examined with certain limitations on the activities and the relations. Only the four end-point relationships were allowed, the finish-to-start, start-to-start, finish-to-finish, and the start-to-finish. This paper aims to extend the previous research by inspecting the influence lines and criticality types if not only these relations, but also point-to point relations are allowed.
