- چکیده:
- چکیده انگلیسی: Claim is a big challenge for the contractors and the owners in construction projects. Claims are considered to be one of the most disruptive events of a project. A suitable claim resolution strategy can prevent the damages to the project and the involved parties. In this research, a mathematical model using game theory is presented to find the optimum strategy for resolving cost-related claims in Design-Bid-Build (DBB) projects. The model investigates the strategies of the contractor and the owner in a consecutive four-step process including: negotiation, mediation, arbitration and litigation. It helps the involved parties to have deeper comprehension of the problem, have a better evaluation of their situation and analyze possible strategies in facing with such circumstances. Considering different scenarios, the points which both parties can agree rationally are proposed with an analytical solution. Finally, two cases of real-world problems are presented and analyzed using the proposed approach and the optimum strategy is determined for each case. Based on the results, some strategies for the owners and contractors are presented in order to be more successful in the claim resolution process.

- چکیده:
- چکیده انگلیسی: In this paper, a two-echelon supplier-manufacturer system has been studied through net present value (NPV) approach. The production rate is finite and constant in both echelons. Also it is assumed that there is a lead-time between the first echelon and it is getting to the second echelon. It is also assumed that the lot-size of manufacturer (second echelon) is m times larger than the supplier’s factors (first echelon), and the supplier can receive wares (the raw material) from the manufacturer in a cycle through several shipments, due to the point that shortage is not allowed. So, it is supposed that the supplier’s production rate is greater than manufacturer’s. The aim is to determine the optimal lot-size of each echelon such that the NPV of the total cost of system is minimized. After approximating the NPV objective function via Maclaurin expansion in both zero and non-zero lead-time cases, an exact algorithm is presented to find optimal solution of the presented model. Based on the results, the two approaches of average cost and NPV do not lead to a same result, and non-equivalency is occurred in this case.
