针对云制造环境下无需求偏好的制造资源优化配置问题,在充分考虑制造服务需求方和云制造服务平台运营方利益的基础上,利用博弈论调和与解决冲突的特点,将制造资源优化配置多目标优化问题转化为非合作博弈问题,分别以制造服务需求方和云制造服务平台运营方作为博弈方,以服务质量指标和柔性指标多目标优化函数作为博弈双方的收益函数,建立了云制造环境下的制造资源优化配置非合作博弈决策模型,并采用改进的带精英策略的快速非支配排序遗传算法对模型进行求解,实验结果表明了该模型和算法的可行性和有效性。 相似文献

针对网络化制造联盟企业的制造资源配置评价问题,建立了成本收益数据包络分析数学模型,提出了以此为核心的制造资源配置评价方法。该评价方法基于数据包络分析的基本思想,将制造资源配置评价问题映射为制造资源配置的成本收益分析问题,应用完全成本分析和作业成本分析方法,建立网络化制造联盟企业制造资源的自营配置成本、外包配置成本和制造资源配置的收益价值模型。在此基础上,建立制造资源配置评价的成本收益数据包络分析模型,并提出资源的优化配置策略。最后,以实际运营的新产品快速开发网络化服务平台为例,验证了分析模型的有效性和实用性。 相似文献

时间、质量、成本和服务是影响现代制造企业竞争力的关键因素。为此,在制造网格中,需要设计一个合理高效的制造资源优化配置方法,从而为每个制造任务寻找到最适合的制造资源。在对网格制造资源优化配置过程中的一些概念进行形式化定义和描述的基础上,基于物理网络,详细论述了制造资源的网络结构模型及其性质;然后以此为基础,提出了应用逐步筛选的方法进行制造资源的优化配置,从而搜索出满足制造任务需求的T,Q,C,S性能指标的最佳制造资源。最后通过一个实例验证了此方法的正确性。 相似文献

在制造资源配置过程中,针对不同生产设备为了追求任务负载而存在的自由竞争关系,引入博弈论描述设备之间在任务负载上的相互制约关系。提出基于非合作博弈的制造资源优化配置方法,把生产设备映射为非合作博弈制造资源优化配置模型的局中人,建立局中人的策略及其收益函数。利用模糊聚类分析的方法对博弈局中人进行聚类,进行Nash均衡的求解。通过实例与遗传算法、禁忌搜索、粒子群算法进行比较,结果表明基于非合作博弈的制造资源优化配置方法获得的任务负载策略能够保证生产设备总体具有更高的利用率,由此,验证了算法的有效性和正确性。

Cloud manufacturing (CM) is a new type of networked manufacturing model, which is proposed in 2010. Optimization technology is one of the key techniques for CM operation, which are used for the efficient integration of manufacturing resources. In all kinds of manufacturing resources, the machining equipment is one of the most important resources. Using optimization techniques to achieve optimal selection of machining equipment is rarely studied in the CM. In order to handle the optimization selection of machining equipment in CM, comparing with the existing resources optimal configuration, an optimal selection strategy is introduced for the machining equipment in CM. In the selection strategy, first, a multiple objective and binary integer programming model is proposed to describe the optimal selection of machining equipment in CM. Second, after analyzing the mathematical model and the real-world problem of the machining equipment selection in CM, the priority method is adopted to convert the multiple-objective problem into a single-objective problem. Third, an improved particle swarm optimization (IPSO) algorithm based on a novel encoding scheme and fitness function is presented to solve the single-objective mathematical model. Finally, the simulation experiments verify the effectiveness of the IPSO algorithm and show that the selection strategy is more objective and effective to help the client select the machining equipment in the CM than current resources optimization model. This research provides a theoretical support for the development of CM. 相似文献

The rapid progress of information and networked technologies, especially Internet/Intranet and Web techniques, is driving a fatal revolution of manufacturing modes/enterprises. Networked manufacturing, as a novel manufacturing mode, has caused profound interest in academic and industrial areas. However, during the transformation from the legacy manufacturing mode to the networked manufacturing mode, there exists a bottleneck, that is, how to integrate the legacy manufacturing resources into networked manufacturing systems. Focusing on this problem, this paper is mainly concerned with developing a novel platform for the configuration and encapsulation of legacy manufacturing resources in networked manufacturing systems. The key point to implement this platform is to adopt a Java solution and mobile agent technologies. With the Java solution, the basic framework for this platform can be realized. Through adopting mobile agent technologies, e.g. Aglets, the encapsulating templates and interfaces for all kinds of manufacturing resources can be developed. Based on the dispatch/return mechanisms of mobile agents, the configuration and encapsulation, information integration and share functions for legacy manufacturing resources can be accomplished well. 相似文献
