Negative weights in network time model

Zoltán A. VATTAI, Levente MÁLYUSZ

Frontiers of Engineering Management 2022, Volume 9, Issue 2, Pages 268-280 doi: 10.1007/s42524-020-0109-1

Abstract: Time does not go backward.Previous network techniques (CPM/PERT/PDM) did not support negative parameters and/or loops (potentiallyMonsieur Roy and John Fondahl implicitly introduced negative weights into network techniques to representplan), and a surprisingly flexible and handy network model can be developed that provides all the advantagesreview the theoretical possibilities and technical interpretations (and use) of negative weights in network
