Modeling and simulation: social force model modified by Helbing model in fast pass system

This paper introduced Helbing’s social force model, modified it with game theory. Then how individuals in the space behave in dynamic non-cooperative games was described, different macro grouping characteristics were obtained. Individual behaviours at the micro level were simulated. Setting different parameters and conditions of the model, the macro effects of individual behaviours were observed. The overall behaviour of the system was studied. It could be used to guide the allocation of public resources.

PROFIT DISTRIBUTION IN IPD PROJECTS BASED ON WEIGHT FUZZY COOPERATIVE GAMES

Integrated Project Delivery (IPD) is regarded as an effective project delivery method that can deal with the challenge of the rapid development of the architecture, engineering, and construction (AEC) industry. In the IPD team, the alliance profit is not distributed fairly and effectively due to uncertainty, preventing the achievement of the IPD project goals. This study focuses on optimizing the profit distribution among stakeholders in IPD projects and uses quadratic programming models to solve fuzzy cooperative games in the IPD. A payoff function is used in the fuzzy alliance to determine the characteristics of the interval-valued fuzzy numbers, and different weights of the alliance and the efficiency of the player’s participation in the IPD are considered in the profit distribution. A case study is conducted, and the results of the proposed method are compared with those of crisp cooperative games. The results show that the fuzzy cooperative game increases the profit of participants in IPD projects. It is more practical to use weight fuzzy cooperative games than crisp games to express imputation. Moreover, the quadratic programming models and methods result in a fair and efficient profit distribution scheme in IPD projects.

An Adaptive Model of Demand Adjustment in Weighted Majority Games

This paper presents a simple adaptive model of demand adjustment in cooperative games and analyzes this model in weighted majority games. In the model, a randomly chosen player sets her demand to the highest possible value subject to the demands of other coalition members being satisfied. This basic process converges to the aspiration set. By introducing some perturbations into the process, we show that the set of separating aspirations, i.e., demand vectors in which no player is indispensable in order for other players to achieve their demands, is the one most resistant to mutations. We then apply the process to weighted majority games. We show that in symmetric majority games and in apex games, the unique separating aspiration is the unique stochastically stable one.

Game-theoretical approach to payoff distribution in joint construction of transportation and engineering networks

The article discusses a game-theoretical approach to payoff distribution between the construction participants during the transport and engineering networks construction. The construction participants can be both the owners of land plots or buildings, and the administrative personnel of settlements and states. It is shown that payoff distribution between the participants should satisfy two principles: dominance and fairness. To determine fair payoff, the mathematical apparatus of cooperative games is used and the Shapley vector is calculated. Options for the implementation of a construction project for 4 and 8 participants are being considered. The use of the Lutsenko formula, which greatly simplifies the calculation of the Shapley vector components for the considered problem of transport and engineering networks construction, is discussed.

Games theory and strategic alliances: applications to British Russian partnership

PurposeThis conceptual paper examines the need for viable theoretical models of international learning alliances in the light of cooperative games and complexity in two distinguished educational settings. Game theory is used to demonstrate the need for the top managerial executives to acquire a detailed understanding of decision makers' behaviours and trigger the deployment of complex analytical methods. The paper scrutinizes Russia's pursued aggressive approach using shock therapy, also suggest the critical need to reform policy.Design/methodology/approachCombining the critical analysis of (1) cooperative games and (2) adaptive systems structures, a dependable model is derived, which sets the baseline for determining the role of costs and gains. The analysis is supported using a real-world example of an alliance between British University (the X and Y alliance) and Russian University. It also emphasizes the importance of both internal and external pressure variables closely connected with the cooperative games, adaptive system and shock therapy.FindingsTwo features of alliances have been emphasized. The first is the importance of informal relationships in the evolution of partnerships and of cooperation. This is a well-known factor in the success of any relationship. Especially in international partnerships, empathy at the individual level is perhaps necessary to bypass the influence of historical and cultural differences that are barriers at the macro level, preconditions rather than consequences of successful policies and contractual arrangements at the level of organizations and governments. The second feature is interdependence at the cost–benefit level and in the domain of decisions. The cooperation of both partners is required to realize payoffs.Practical implicationsThe implication of this paper is a guideline for regulators and policymakers designing worldwide alliances in higher education. In addition, this paper covers an interesting domain that could be of interest to organizations involved in forming strategic alliances, developing and re-engineering policies for strategic coalitions and setting future profitable payoff relationships within the contextual limitations of X and Y.Originality/valueThis paper creates new knowledge by concisely examining the meaning of strategic alliances in the context of the global education industry.

Games and enculturation: A cross-cultural analysis of cooperative goal structures in Austronesian games

While most animals play, only humans play games. As animal play serves to teach offspring important life-skills in a safe scenario, human games might, in similar ways, teach important culturally relevant skills. Humans in all cultures play games; however, it is not clear whether variation in the characteristics of games across cultural groups is related to group-level attributes. Here we investigate specifically whether the cooperativeness of games covaries with socio-ecological differences across cultural groups. We hypothesize that cultural groups that engage in frequent inter-group conflict, cooperative sustenance acquisition, or that have less stratified social structures, might more frequently play cooperative games as compared to groups that do not share these characteristics. To test these hypotheses, we gathered data from the ethnographic record on 25 ethnolinguistic groups in the Austronesian language family. We show that cultural groups with higher levels of inter-group conflict and cooperative land-based hunting play cooperative games more frequently than other groups. Additionally, cultural groups with higher levels of intra-group conflict play competitive games more frequently than other groups. These findings indicate that games are not randomly distributed among cultures, but rather relate to the socio-ecological settings of the cultural groups that practice them. We argue that games serve as training grounds for group-specific norms and values and thereby have an important function in enculturation during childhood. Moreover, games might server an important role in the maintenance of cultural diversity.
