4.2.1. Application of chicken game in resolving the probabilistic conflicts during the construction
Many factors can affect the finishing of the project on time. One of them is delaying on delivery of material on site which will cause a delay the project. Assuming in a project, 70 percent of work has been implemented. At this time,
unavailability of some materials in the market causes an interruption in the project. On the other hand, this activity is in critical path according to the work schedule which every interruption on that can directly affect the project completion date and will lead to the delay. In this situation, the dispute arises between client and contractor, since on the one hand, the client discerns this delay as a non-excusable delay which due to the contractor’s fault but on the other hand the contractor tries to justify this situation to change the delay to excusable delay for getting the additional time from the client. In this situation, the contractor has two ways or strategies:
1. Taking the short-term corrective action such as work over time
2. Does not take any short-term corrective action and continue the project implementation with the previous speed.
Chicken game is one kind of game theory for modelling the situation of this conflict between contractor and client. For modelling this game in the framework of game theory, first it must be written in the matrix form.
