摘要
从后悔理论入手,分析后悔理论用于出行行为分析的2种一般形式:多项选择集和多属性决策,研究后悔理论在有风险和无风险条件下的模型结构,提出基于随机后悔最小化的出行路径选择行为分析模型,结合算例对比分析随机效用最大化模型和随机后悔最小化模型用于出行路径选择结果的异同。研究表明,出行者做决策时为避免未选择方案比选择方案表现的更好,试图将预期后悔最小化,而不是预期效用最大化。且对于多属性的备选方案,出行决策是半补偿性的。
Starting from the regret theory,two generalization forms（multinomial choice sets and multi-attribute decision-making） of regret theory applied to travel behavior research are discussed.The paper analyzes model construction of regret theory under riskless and risky travel behaviors context,and proposes a travel route choice behavior model based on random regret minimization.Through a computational example,the travel route choice result by using random utility maximization model is contrasted with that by using random regret minimization model.The results show that by avoiding situation where non-chosen alternatives perform better than the chosen one,travelers aim to minimize anticipated regret rather than to maximize anticipated utility.As to multi-attribute alternatives,the travel decision-making is semi-compensatory.
