Graphical Evaluation and Review Technique (GERT): The Panorama in the Computation and Visualization of Network-Based Project Management
Abstract
This chapter focuses primarily on Graphical Evaluation and Review Technique (GERT), one of the intriguing techniques used for network-based management. It is a stochastic network technique and has many advantages over the conventional Critical Path Method (CPM) and Programme Evaluation and Review Techniques used for project management. The formulation of the GERT network for linear situation can be development by analytical techniques (such as signal flow graph theory); thus for a non-linear and other complex conditions, the Q-GERT (included Queueing Concepts) is used. To reinforce the importance of GERT and Q-GERT, a firm study is carried out on the limitations of the CPM and PERT. Thus, a solid comparison of GERT network with the CPM and PERT network is done not only to emphasize the applicability of the network but also to validate of the network. The scheduling of concrete formwork systems are considered for the comparison.
