The Equilibrium Sensitivity And Evolution Mechanism Analysis Of Construction Disputes Based On The Hypergame

Construction disputes are various nowadays, the main body involving are complex. After dispute occurrence in construction project, for subjective or objective reasons the exchange of information between each other (strategy, preferences) is often incomplete. Disputes under the condition of information asymmetry, misunderstandings are produced often between the parties, In the case of dispute with misunderstanding, how a dispute situation develop, which is the article to explore direction. This paper tries to use hypergame analysis the construction disputes. After research review the construction disputes, fuzzy preference, hypergame, equilibrium solution robustness, sensitivity analysis and so on, this research is mainly done the following work:First of all, through the questionnaire survey the construction disputes probability, dispute misunderstandings probability, the causes of misunderstanding, the source of the misunderstanding, resolving misunderstanding method and cost, the probability of multiple game, and then processes and analyses the survey data.Second, introduced the theory and elements of hrpergame, including players, strategies feasible situation countermeasures, preference vector, hrpergame model and the equilibrium of hypergame. And by means of AHP to solve the initial preference vector of hypergame (evaluation standard weight, each situation preference utility value), so as to solve the initial equilibrium solution. To test the stability of the initial equilibrium of hypergame, using the method of sensitivity analysis. By changing the dominance of pairwise comparison matrix of the evaluation standard, so as to give a disturbance to the equilibrium, in order to test the stability of the equilibrium.Again, in several rounds of dynamic hypergame, the game dynamic evolution mechanism are discussed in this paper. Starting from the four kinds of attitude of players to the equilibrium, separating two improvement path, respectively are based on the evolutionary path of robustness and efficiency in the process of analysis. In the process of analysing, define the extent of misunderstanding, the amount of information, information cost, such as concept. Put forward some approaches to strengthen the equilibrium. And analysis the inner mechanism of hypergame equilibrium generated, and discussed the three conditions of equilibrium solution to generate (known conditions, speculation conditions and assumptions) issues, such as definition, origin, probability.
