Optimal risk allocation in alliance infrastructure projects: A social preference perspective

Xiang DING, Qian LI

Frontiers of Engineering Management 2022, Volume 9, Issue 2,   Pages 326-336 doi: 10.1007/s42524-020-0145-x

Abstract: This study presents a quantitative approach based on modeling alliance member (AM)’s inequity aversion(IA) to analyze risk-sharing arrangements in an alliance project.Fehr and Schmidt’s inequity-aversion model is integrated into modeling partner’s utility.risk-management effort simultaneously.preference negatively affects AL’s optimal risk-sharing ratio.

Winner determination problem with loss-averse buyers in reverse auctions

Xiaohu QIAN, Min HUANG, Yangyang YU, Xingwei WANG

Frontiers of Engineering Management 2017, Volume 4, Issue 2,   Pages 212-220 doi: 10.15302/J-FEM-2017019

Abstract: Reverse auctions have been widely adopted for purchasing goods and services. This paper considers a novel winner determination problem in a multiple-object reverse auction in which the buyer involves loss-averse behavior due to uncertain attributes. A corresponding winner determination model based on cumulative prospect theory is proposed. Due to the NP-hard characteristic, a loaded route strategy is proposed to ensure the feasibility of the model. Then, an improved ant colony algorithm that consists of a dynamic transition strategy and a Max-Min pheromone strategy is designed. Numerical experiments are conducted to illustrate the effectiveness of the proposed model and algorithm. We find that under the loaded route strategy, the improved ant colony algorithm performs better than the basic ant colony algorithm. In addition, the proposed model can effectively characterize the buyer’s loss-averse behavior.
