Abstract: Pedestrian simulation is widely used on the assessment of facility design and crowd safety control. It proposed a grid-based model of queue simulation system considering human physiology and psychology. Both logic queue system and animation queue system are modeled separately. Deadlock deal mechanism is designed. The proposed model established a good interface between the pedestrian behavior, queue system and animation. It can reproduce phenomenon like traffic shock wave effectively. A case study is shown by simulation of ticket vendor machine layout assessment in Beijing South Railway Station. It concluded that the model is effective and adapted to large scale systems.

Abstract: Classification Based on Association (CBA) algorithm built a classifier based on the association rules, but without considering the uncertainty in the classification problem. This paper proposed a Bayesian network classifier based on the association rules. The algorithm extracts the candidate set uses association rules and classification algorithms related to the network, then uses “greedy hill-climbing algorithm” to learn network structure to get a better topology, and verify that this algorithm is valid on handwritten numeral recognition.

Abstract: This paper is based on the athlete’s competitive ability theory model, chosing seven antagonistic events to study. By mathematical dealing with every event’s competitive ability factors and comparing the weight number of each factor within and between sub event-groups to get the different or same characteristics in these events. The result is that the weight numbers in different events are different, which reflects the imbalance development of competitive ability. Specials’ competitive ability characteristics focus on the consistent weight numbers of condition ability, sport tactics and sport intellect and the difference of weight numbers of body shape, body function and sport technique.

Abstract: the study has taken net-partition oppositional group-event sports hierarchy elements as research platform, and has calculated the four-level elements’ relative weight of net-partition oppositional group-event sports structure hierarchy by using the AHP analyze method and examine the subjective consistency of weight evaluation with consistency factors, then analyze the group-event competition characteristics combined with elements weight.

Abstract: The project carrying on in the complex environment was affected by many factors. Project risk management is to manage the uncertainty elements in the process of project development to realize the smoothly running of the project. This paper provided the process method carried on the control to each type of resources in risk management investment in the project risk management process, built up process method in controlling project risk to reduce the threat that risk brings to the project, and attained the lowest damage of the project. Consecutively, risk management can be made to become one of the core parts in project management by excavating the project potential opportunities.

Abstract: This study builds with AHP (Analytic Hierarchy Process) the teaching ability system for martial arts teachers in institutions of higher learning, which falls into four layers: destination layer, criteria layer, feature layer and index layer. The destination layer refers to the teaching abilities of martial arts teachers; the criteria layer consists of two criterions, which are professional practice ability and teaching ability; the feature layer is made up of seven features, including martial arts skills, martial arts organization and judgment, martial arts culture, martial arts graph recognition and routine design, basic quality, basic skill and teaching organization; and the index layer consists of 19 indexes, which are self-defense skills, routine exercise skills, offensive and defensive skills, martial arts organization, martial arts judgment, schools of martial arts, martial arts culture, martial arts graph recognition, martial arts routine design, professional ethics, teamwork, humanistic quality, language expression, student management, teaching research, course design, teaching practice, teaching evaluation and teaching guide. The results show that the top five impact factors for the teaching ability of martial arts teachers in institutions of higher learning are course design, routine exercise skills, teaching practice, teaching research and martial arts routine design.

Abstract: Mangrove forest has various functions, such as wind and wave prevention, embankment protection, biodiversity and ecological balance maintenance, which is with high value in the ecological, social and economic. Hainan is the region where the type of Mangrove forest is most abundant, its area is biggest, its growth vigor is best. Hainan mangrove forest is very important to the ecological, scientific research and tourism. Hainan International Tourism Island Construction, which had been proved by state council, will bring great influence on the quality and range of Hainan mangrove forest. It is with positive guiding significance to the changing monitoring of mangrove forest and projection measures making to obtain the distribution information of Hainan mangrove forest and other land cover types, compare and analysis the area changing of all kind of land cover types based on Remote Sensing and Geographic Information System.

Abstract: The purpose of the paper is to study the conflict resolution in virtual teams. Multi-agent technology is used to simulate the virtual team. In the team, agents adapt the Q-learning algorithm to adjust their behaviors. Through the interaction of virtual members, part of conflicts can be resolved by team members. The experiments are manipulated to study the process of the interaction in the team. The results of experiments show a new rule for conflict resolution emerged from the dynamic interactions of agents. The conclusions show significance on the management of team in real world.
