| 1 | Evolutionary Stable Strategies for Supply Chains: Selfishness,Fairness, and Altruism显示文摘The management strategies of a firm are inevitable affected by individual behavior preferences. The effect of individual preference on the evolutionary dynamics for supply chains is studied by employing replicator dynamics. Each firm has three behavior preferences: selfishness, fairness, and altruism. Firstly, the case that the strategy set of manufacturers and retailers including two pure strategies is considered and the effect of preference parameter on the equilibrium outcome in the shortterm interaction is discussed. Secondly, the equilibrium state in the short-term is always disturbed because the change of the environment, firm's structure, and so forth. Using the replicator dynamics,the evolutionary stable strategies of manufacturers and retailers in the long-term interaction are analyzed. Finally, the extend case that the strategy set of manufacturers and retailers include three pure strategies is investigated. These results are found that the strategy profile in which both manufacturer and retailer choose fairness or altruism, or one player chooses fair or altruistic strategy and the other player chooses selfish strategy may be evolutionary stable, the stability of these equilibria depends on the the preference parameters. | Caichun CHAI Hailong ZHU Zhangwei FENG | 2018 | Journal of Systems Science and Information2018，9，6： | 0 |
| 2 | Spatial sight analysis of Hangzhou Xiaoyingzhou based on tourists’landscape preference显示文摘Tourist preferences are important for the high-quality planning and design of recreation spaces.The famous scenic locale of West Lake in Hangzhou,China,is used as an example in this study.Based on multi-source data(e.g.,online comments,and tourist photographs),we used content analysis,kernel density estimation,and image semantic segmentation technology to determine the spatial distribution of tourists’landscape preferences.We analyzed these spatial sight characteristics from the viewpoint,sight distance,and perspectives.The results show that tourists’landscape preferences are mainly concentrated on landscape architecture for recreation.The viewpoints of these preferences are concentrated in the north-south embankmentdfar beyond that of the east-west embankment.The preferences also show a spatial sequence in terms of sight distance,and the best visual effect is the open platform at the north and south islands of Xiaoyingzhou.From the perspective of vision,the degree of spatial openness in the tourists’landscape preferences is proportional to the distance of vision;the two factors have a convergent relationship.The discussion of the characteristics of tourists’landscape preference and space sight creation in Xiaoyingzhou provides a reference for the quality improvement of island recreation space. | Yiying Chen Qiwei Ma Lihua Xu Yijun Shi Zhangwei Lu Yaqi Wu Mao Feng | 2023 | Frontiers of Architectural Research2023，12，6： | 0 |
