以一个供应商和制造商组成的两级供应链系统为研究对象,根据交货期影响供应链定价的特点,以企业收益最大为目标,建立基于产能的面向交货期的供应链协同定价决策模型,分析了供应商如何根据自身的交货期和产能来确定产品的最适售价。通过数值分析,论证模型的有效性。此模型可以为供应链协同企业如何根据自身的产能来决策交货期和定价提供有益的指导。 相似文献

在分析企业准时交货的影响因素和企业内部订单处理流程的基础上,针对制造型企业在准时交货中存在的问题,提出了面向交货期的生产协同模型.根据订单处理和车间调度的复杂性,并结合Multi-Agent的自主性、协调性等特点,探讨了面向交货期的生产协同系统的框架结构与多代理的功能分类,建立了基于Multi-Agent的面向交货期的生产协同物理模型.最后用一个案例分析了所建立的生产协同模型在企业中的应用,缩短了交货期,证实了所建模型的可行性. 相似文献

Color tunable thin film polymer solar cells have demonstrated the potentials of a wide applications in photovoltaics printing, which is significant for ink pollution reduction and energy saving. This work presents a new effective approach to realize color-tuning photovoltaic cells with optical microcavity structures. Aluminum-doped zinc oxide is utilized as electron transport layer material. With its high electrical conductivity, the thickness tuning range can be quite large, which means the cavity length has a wide variation range. It thus provides sufficient space for optical thin film design to obtain multi colors. By the transfer matrix method, device reflection and absorption spectra are numerically investigated. Based on that, the optical principles for color tunability are explored. In further step, the relationship between device photovoltaics performance and reflective colors are also discussed. Finally, the color coordinates and luminosities are calculated. As results, the colors of the devices designed are capable to cover a relatively large region in Commission Internationale de l′Eclairage(CIE) 1931 x, y chromaticity diagram, which is available to be integrated into the advertisement poster boards, building wall printing and other display applications. 相似文献

在研究国内外相关研究现状的基础上,针对托盘租赁企业联盟情况下的分配问题进行分配策略研究.笔者通过引入Shapley值构造原理及AHP分析法,在分析托盘租赁联盟收益组成及盟员风险承担能力的同时,提出了基于可量化收益、不可量化收益及风险承担能力的收益分配模型,此种分配方案是实现个体理性与群体理性的保障,是联盟保持稳定的必要条件.最后通过算例分析,验证了这种分配方法的合理性. 相似文献
