Critical activity and inflexible activity are two important types of activities in the activity-on-arc network with generalized precedence relations (AOA-GPRs), which are very useful for project managers and practitioners to allocate and adjust resources in practice. This paper discusses and defines some important concepts, and studies the effect on the(More)
This paper discusses the intuitive meanings of critical resource and gives its strict definition for the purpose of reducing project makespan. And then, an algorithm to identify critical resources is presented and the complexity of the proposed algorithm is analyzed. The results of a computational example manifest that we can shorten project makespan,(More)
The network with generalized precedence relations (GPRs) is very useful for project managers. However, it is limited to be used widely in real projects due to its very complex graphical representation which makes it difficult to be understood by the project managers and practitioners. Therefore, some methods are proposed to make the GPRs model structure(More)
