Abstract
In this Paper, we develop the two kind of models to explain the consumer behavior at the comercial district in a city crnter. The first is the decision-making model which is based on the expected utility criterion, and the utility function is estimated by the conjoint analysis. The second is the excursion behavior model which is based on the nonregular stochastic model. We applied these models to the decision-making of shopping and leisure behavior, and obtaind satisfactory results.
