Game theory is introduced to deal with the conflict that several pedestrians intend to move to the same site. A pedestrian is either a co operator (C) or defector (D) when he or she wants to move into the same lattice as other pedestrians. Moreover, he or she could change the strategy (C or D) in the next conflict. The fundamental diagram of pedestrian flow in the channel has been investigated in details, and differences from the model with random sequential update rule have been observed. The co operators fraction is shown to exhibit an interesting non-monotonic dependence on pedestrian density. It is interesting to find that change of co operators fraction alters exponentially before the system comes to steady state. How the parameters p and q in the payoff matrix of game influence mean flow and co operators fraction is also investigated.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121342145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water depth is one of these important factors. Also water depth participates in the later inversion algorithm to affect several parameters (wave period, signal-to-noise ratio, etc.) precision. Firstly, according to the dispersion relation, it analyses the effect on those parameters qualitatively. Then the experiment results verify these analyzed results. It proves that in the inversion algorithm, if the water depth used is greater than the actual one, the signal-to-noise ratio increases, and the wave period decreases. On the contrary, the signal-to-noise ratio decreases, and the wave period will increase.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122298010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Green credit extended so far is already more than 1 trillion Yuan in China, and huge growth is expected with further development of a low carbon economy. As green loan undertakes social responsibility, such as environmental protection and energy saving, and is one of the key factors in policy decisions, the traditional credit scoring system and risk evaluation model can not be used since here only financial and management factors are considered. In this paper, a green credit scoring system is presented which introduces new environment and energy factors. A SVM risk assessment model is created on this basis. Finally, a real-world dataset is applied to test the green credit scoring system and the SVM risk assessment model. The result shows that the new green credit scoring and SVM risk assessment models are effective.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127901585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking into account mixed behaviors, where distinct Cournot-Nash (CN) players control certain portions of users, and the other users follow the user equilibrium (UE) principle, we establish the existence of meaningful road pricing in this case to decentralize a system optimal as the multiple behavior equilibrium. Considering the effect of the road pricing, some UE players may chose to give up their travel or change their travel tools, so we assume that the demand of UE players is elastic. There propose a Stackelberg leader-follower game for this problem, where the government is the network manager acting as the leader aiming to optimize network performance charging to part of network users, and the follower are the elastic demand UE players and CN players on the network. The particle swarm optimization (PSO) algorithm is used to solve the proposed model and a numerical example is provided. The computation results show that the road pricing strategy can obviously improve network performance in terms of reducing system congestion.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130806725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
