基于多AGENT的虚拟企业伙伴选择系统 总被引:9,自引:2,他引:7
伙伴选择是虚拟企业建立过程中的核心问题。在基于多agent的虚拟企业体系结构基础上,通过本体驱动的虚拟企业目标体系描述与分解,将虚拟企业伙伴选择问题表示为分布式约束满足和优化问题,并进一步以agent谈判的方式来求解该问题,最终得到优化的伙伴选择方案。本体驱动的虚拟企业目标描述与分解方法,为不同企业之间的谈判提供了通用词汇;用分布式约束满足和优化的方法对问题进行形式化描述,可以为企业之间的谈判提供论域和决策支持。分布式约束满足和优化方法的应用,为解决虚拟企业伙伴选择问题提供了一种新思路。 相似文献

虚拟企业伙伴选择的粗糙集方法 总被引:6,自引:0,他引:6
将粗糙集理论应用于虚拟企业合作伙伴选择中,提出了基于粗糙集理论的虚拟企业伙伴选择的模型和方法.该方法根据各潜在伙伴企业的样本数据集建立决策系统,以伙伴选择的评价指标作为属性,从中挖掘出反映评价指标本质关系的重要属性以及伙伴选择知识规则.这些规则很好地描述了有限样本中所反映出的属性之间的本质特征,运用这些规则可对伙伴选择数据库中的其他样本有效地进行伙伴选择.应用实例表明,该方法是正确有效的. 相似文献

To cope with the rapidly changing manufacturing environment, enterprise collaboration is getting increasingly more attention than ever before. The virtual enterprise (VE) is a concept that supports temporary alliances of manufacturing enterprises that have various collaboration models, such as extended enterprise, networked enterprise, concurrent enterprise, etc. Selection of trustworthy partners and trust building are important in virtual domains because they have largely been affecting the success of a VE. However, because of its complexity of trust, trust models in the literature are limited in their ability to cope with dynamic and virtual environment. In this paper, we propose a trust evaluation method of supporting enterprise collaboration and maximizing the satisfaction of cooperation. In this context, trust means the goal achievement probability. Trust value of an enterprise can be obtained by a fuzzy inference system whose rule-base is based on the top-level goal of a VE. According to the selector’s preference, various rules can be applied to trust evaluation. For further study, the planning and scheduling problems should be considered along with the trust-based partner selection for collaboration among manufacturing enterprises. 相似文献

虚拟企业要达到预期的目标,取得预期的利润,就必须成功规避运行中的风险.根据虚拟企业合作运营区域的分布性以及联盟企业之间关系多样性的特点,采用分布式决策的思想对虚拟企业的风险进行管理.以盟主和各盟员构成非团队关系、并且各盟员可能存在机会主义行为的虚拟企业为研究对象,针对其风险管理中盟主和盟员之间存在的道德风险问题,建立了虚拟企业风险管理的分布式道德风险模型,叙述了模型的求解过程,分析了盟员风险偏好对决策的影响以及盟员的道德风险给虚拟企业风险管理带来的不利影响.仿真分析表明,通过上层模型中的激励相容约束可以消除盟员在风险管理中可能出现的机会主义行为,从而保证虚拟企业风险管理的顺利进行. 相似文献

Cooperation coordination in virtual enterprises 总被引:5,自引:1,他引:4
Coordination of activities is a determinant element in virtual enterprises. Proper coordination policies supported by flexible coordination mechanisms are necessary to ensure the cooperation among partner enterprises. This paper presents the PRODNET approach to support coordination in virtual enterprises. The adopted model considers on flexibility and configurability as the key aspects to cope with the large diversity of expectable scenarios and operating policies in the virtual enterprise environment. A workflow based approach for coordination is described and especial emphasis is put on a multi-level coordination view. The developed software modules that support the coordination mechanisms are presented, and finally some directions for further research are given. 相似文献

Partner selection is a major issue in the formation of a virtual enterprise. In practice, in the partner selection process, the information about the candidates and their performances are incomplete and uncertain. Vague sets theory is one of the methods used to deal with uncertain information. In this paper, a new method based on vague sets is proposed to deal with the partner selection problem in the formation of a virtual enterprise while the factors of satisfaction degree, due date, cost and the precedence of tasks are taken into account. On the basis of the agreement index of satisfaction degree, the formulated partner selection problems are interpreted so as to maximize the minimum agreement index. To solve the problem, an improved particle swarm optimization (PSO) algorithm is proposed. Finally, the simulation of a numerical example demonstrates that the method is effective. 相似文献
