MAS构建中的主观协调和客观协调研究

文章对MAS中协调的概念进行了分析,提出了MAS中同时存在主观协调和客观协调的观点。以两个agent堆积木块为例,阐释了主观协调和客观协调的本质区别。根据主观协调和客观协调对MAS构建的影响,结合对JAFMAS平台的分析,提出可以建立主观协调模型到本地模型、客观协调模型到社会模型的映射,从而提高基于JAFMAS平台开发MAS应用的效率。

应用企业建模方法建立企业模型，运用提出的Agent构造方法对模型进行Agent转化，得到企业多Agent系统模型。这一开发方法分为两个阶段：建模阶段和Agentify阶段。两阶段相承接构成一个完整的系统方法，为实际应用提供了理论指导与方法依据。以企业管理诊断系统开发实例进行阐述，证明了方法的有效性。     

容器编排工具中部署工作节点的资源优化

随着云计算飞速发展, 以Docker为代表的容器技术逐渐被重视. 目前, 3种常见的容器编排工具有Kubernetes、Docker Swarm和Rancher. 然而, 现有的容器编排工具在所有工作节点的总容量超标时, 将会有响应时间长和资源占用较多等问题. 因此, 本文设计LSD (least space unused)算法以及LRU-SD (least recently used and space unused)算法, 并应用于3种编排工具中. 当总容量超出上限时, 则选择删除不工作的节点并且增加新的工作节点. 做法上, LSD算法是删除剩余空间最少的工作节点, LRU-SD算法先考虑删除最久未使用的节点, 当有多个符合要求的节点时, 则删除剩余空间最少的工作节点. 实验部分, 分析与比较使用不同算法对3种容器编排工具的影响, 包含响应时间、CPU和内存. 实验结果发现, LSD算法、LRU-SD算法和LRU算法不仅能够提高编排工具的响应时间, 还可以增加资源的使用率. 同时, 在提升CPU的使用率方面, LRU-SD算法的效果最好.

Coordination for Internet Application Development

The adoption of a powerful and expressive coordination model represents a key-point for the effective design and development of Internet applications. In this paper, we present the TuCSoN coordination model for Internet applications based on network-aware and mobile agents, and show how the adoption of TuCSoN can positively benefit the design and development of such applications, firstly in general terms, then via a TuCSoN-coordinated sample application. This is achieved by providing for an Internet interaction space made up of a multiplicity of independently programmable communication abstractions, called tuple centres, whose behaviour can be defined so as to embody the laws of coordination.     

System Virtualization Tools for Software Development

The configuration complexity of preproduction sites coupled with access-control mechanisms often impede the software development life cycle. Virtualization is a cost-effective way to remove such barriers and provide a test environment similar to the production site, reducing the burden in IT administrators. An eclipse-based virtualization tool framework can offer developers a personal runtime environment for launching and testing their applications. The authors have followed a model-driven architecture (MDA) approach that integrates best-of-breed virtualization technologies, such as Xen and VDE.

Development Support Tools for Enterprise Resource Planning

Implementing an enterprise system involves capturing all information necessary to make business processes work in an integrated fashion, and reflecting this integration in source code. Enterprise resource planning implementations should also exploit reuse of existing system elements. ERP tools typically work on top of a framework, using prefabricated modules to create customized variants of the system. Among the free and open source ERP systems, only ERP5 offers a comprehensive set of tools tailored to its framework that, together with other off-the-shelf tools, provide support for creating new modules and entire new systems.     

Case-Based Knowledge Management Tools for Software Development

Modern software development is a knowledge-intensive activity. The proliferation of development tools, rapidly changing technology, and increasing complexity and diversity of application domains all increase the cognitive burden placed on software developers. General purpose programming languages and CASE tools offer little relief from these problems. Knowledge management tools are needed that can effectively capture and disseminate software development knowledge that applies to the domain-specific needs of an organization. This knowledge is not static, but evolves with technology and the changing needs of the organizations development practices, customer base, and business milieu.This paper presents an infrastructure that supports evolving knowledge through case-based techniques and domain analysis methods that capture emerging knowledge and synthesize it into generally applicable forms. The approach is less concerned with the veracity of knowledge in its repository than evolving the knowledge toward answers to problems that fit the organizations technical and business context. Implications of this approach go beyond supporting software development to other knowledge-intensive professions where knowledge management tools can be used to support an organizational memory.     

New Approach Targeting Security Patterns Development and Deployment

ABSTRACT

In this paper, we address the problems related to the applicability and usability of security patterns. In this context, we propose a new approach based on aspect-oriented programming (AOP) for security patterns development, specification and deployment. Our approach allows the security experts to deliver their security patterns that describe the steps and actions required for security solutions, including detailed information on how and where to integrate each one. It also provides the pattern users with the capabilities to deploy well-defined security solutions. The pattern users are required to have knowledge in AOP with minimal expertise in the corresponding security solution domain. Moreover, we design and implement the RBAC (Role Based Access Control) model for a Library Circulation system called RBAC-LB. The elaborated RBAC-LB model illustrates all the procedures and mechanisms of the approach phases and provides authentication/access control features for the library system.     

A Development Environment for Constructing Graph-Based Editing Tools

Scientists and engineers use numerous kinds of graph notations to model various objects in the real world and their relationships in an abstract pictorial form. However, developing a specific graph editing tool for each of these notations is often very costly in terms of time and resources. This paper outlines a design of a suitable development environment for constructing graph-based editing tools, based on the requirements analysis of such an environment derived from a survey of more than 60 different graph notations.
