Chapter 1 gives the background,current research process of relatedproblems and summarizes this thesis\'s work.In chapter 2,we study the Brownian motion with holding and jumping on the boundary.We use the resolvent method to obtain the infinitesimal generator because the domain of the infinitesimal generator is essentially the same as the range of the resolvent.Knowledge of this range and of the differential operator determines uniquely the infinitesimal generator.Since the semigroup generated by the DHJ is not strongly continuous,to use the nice property of strongly continuous semigroup in analytic theory,in chapter 3 we show that the dual is strongly continuous and derive ergodicity through spectral radius formulas and finally obtain the ergodic theorem by duality. In chapter 4,we discuss a class of a more general process---one dimensional Feller diffusion proposed by W.Feller in 1954.The Feller diffusion allows the possibility of jumps from boundary to boundary,not only from boundary to the interior.We give the stationary distribution of this process.

However, there still leaves much to think about the agent systems'software engineering process and methods. In this field, some valuable and important works have been put forward, such as MaSE, Gaia, MESSAGE/UML, etc. Each of them pays attention to one or several aspects of agent system, but few of them give enough thought to the dynamic properties of agent system's role-based organization. Most of these works begin with analyzing system's static role models and transforming them into agent models, and then succeeding make detail design and later implementation.

需要指出的是,在MAS研究的数十年来,研究人员已经对Agent体系结构、意图理论等进行了深入的研究,但也许是出于对人工智能的偏爱,现有的对多Agent系统开发方法的研究不够深入,尽管已经出现了一些广为人知的软件开发方法,比如MaSE,Gaia,MESSAGE/UML等,但这些方法并没有清晰地给出其所依赖的概念模型;此外,在基于角色的面向Agent开发方法中,往往对角色概念以及角色与Agent的关系没有给出明确而深入的刻画。

The purpose of this research is to discuss the decision of negotiation types and processes. The conponents of the decision-making of each transaction include "the counterpart" and "the deal". The Potential Value of Social Transaction and The Potential Value of Economic Transaction can distinguish between the "quasi-economic man" and the "quasi-social man", two different types of psychological construction. This research makes a point of dyad according to a quasi-economic man and a quasi-social man which can distinguish among three different dyadic decisions of negotiation types:the dyadic decision of negotiation type between a quasi-economic man and a quasi-economic man, the dyadic decision of negotiation type between a quasi-social man and a quasi-social man, and the dyadic decision of negotiation type between a quasi-economic man and a quasi-social man.
