And three steps to develop multi - agent systems by mas builder are brought forward : decomposing problem , defining agent , implementing task module . then this method is applied to solving distributed workflow problem , with two examples to explain it 并结合masbuilder ? ?一个多agent系统的开发和运行平台，提出基于masbuilder开发多agent系统的三个步骤：问题域分解、 agent定义和任务执行。
Subject choice is a research vision of local government performance evaluation , and its basic theories , system structures , institutional guarantees and operating mechanism constitute the basic problems in subject research region 摘要主体选择是地方政府绩效评估的研究视角，地方政府绩效评估主体选择的基础理论、系统构成、制度保障及运作机制等构成了地方政府绩效评估主体选择研究问题域中的基本问题。
Because of inablity of the handling dead end state , ff does not perform ideally in some planning problem domains such as gripper . in this paper , a new searching method enforced hill - climbing with backtracks is used , and a new method of helpful action ordering is presented 但是, ff规划算法所采用的搜索方法和规划图的使用上都存在很大不足,使得ff规划算法在某些规划问题域中,特别是含有死点状态的问题域中表现不够理想。
Federate developers have to learn how to use the rti library . therefore , the complexity rti interface always diverts the attention of federate developers from the federation problem domain to rti specific technical issue , and distracts their attention from the implementation of simulation functions 联邦成员软件的开发者面临着学习和使用rti库的问题，大量低层接口的编程往往会使联邦开发者的注意力从联邦问题域转移到rti技术细节上去。
Ooa ( object - oriented analysis ) aims to build a analysis model based on class diagram . . but among most oo methods , ooa lacks formal , unified and well - operated measures , only directly finding class diagram by means of analyzing problem domain through domain experience Ooa (面向对象分析)的目的是建立以类图为核心的分析模型，但这些oo方法的ooa阶段对于建立类图大都缺乏规范、统一、可操作性强的手段，只是凭借领域经验通过分析问题域直接得到类图。
Furthermore , we assert that while grid technologies are currently distinct from other major technology trends , such as internet , enterprise , distributed , and peer - to - peer computing , these other trends can benefit significantly from growing into the problem space addressed by grid technologies 此外，我们肯定网格技术不同于当前许多其他技术方向，比如因特网、企业、分布式、点到点计算，但这些其他的方向能因成为网格计算的问题域而获益匪浅。
On the basis of research works related above , an enterprise mhs with good quality of extension and reconstruction is integrated under the direction of design model . this dissertation emphasis on the following aspects : to analysis business processing and capture system demands with use cases . the object - oriented analysis and object - oriented design of the entities in the application domain , the identification of the objects in the application domain and the analysis of the relations of these objects 本文重点进行了以下方面的研究工作：使用用例( usecases )分析业务处理流程，捕获系统需求；用面向对象方法对问题空间中的实体进行分析与抽象，识别出问题域的对象，并分析它们相互之间的关系；研究从对象到关系数据库的映射，用e - r模型进行数据建模、设计物流系统数据库；用uml中类图、对象图、用例图、状态图、顺序图等分别对系统的静态与动态部分建模；运用通用设计模式，建立三级软件体系结构的物流系统模型，将问题域的模型转化为求解域模型；
The paper put forward the model of network security problem domain and analyze the underlying reason of false positive and false negative by using it . at last , the paper bring forward the network security protection architecture based on intrusion detection for a integrated network security cycle 然后，本文提出了网络安全问题域模型，并利用这一模型分析入侵检测系统的误报和漏报产生的根本原因；最后，为构筑完整的网络安全循环，本文提出了建立在入侵检测基础上的网络安全防护体系结构模型。
Outlined the system ' s structure and organization combining the data structure , alternating actions between the user and the system and the system ' s data process function . adopted the object oriented design method to construct the object model of the solution space around the problem domain sub - system and the alternating sub - system of the user and the computer . the design of the programs realized the construction and package of core classes and basic operations such as read , write and change dicom files based on the dicom file services 结合系统数据结构、用户与系统交互行为和系统数据处理功能，概要设计了系统的组织和结构；采用面向对象的设计方法，围绕问题域子系统和人机交互了系统，建立了求解空间的对象模型；程序设计围绕dicom文件服务功能，实现了核心类的构造和封装以及dicom文件的读、写、修改等基本操作。
