从供应链低碳化出发,分析了企业碳配额、碳交易市场中的碳价格以及消费者主观购买行为等因素对企业利润的影响。采用Repast Simphony实验仿真平台和Groovy开发语言,在复杂的不确定市场环境下,对供应链参与方行为进行仿真,建立了引入碳交易因素以后的供应链模型。模型中包含消费者对产品的选择、低碳化运输和采购、供应商选择等市场行为。仿真结果表明,企业碳配额和消费者主观购买行为对企业利润的影响较大,对碳交易市场中的碳价格影响较小,初步验证了模型的有效性。 相似文献

基于多agent的军事物流系统仿真建模方法* 总被引:2,自引:0,他引:2
针对军事物流系统复杂性和不确定性的特点,提出了一种基于多agent的系统仿真建模方法。采用中间到两端的多层agents组织方式,引入agent分区概念对agent行为分别进行详细描述。在基于中间层agents逻辑模型的基础上抽象上层agents和下层agents。通过中间层各agent的活动映射而构造的下层agents负责特定的事务处理。中间层agents负责协调下层agents的信息传递,并与上层agents进行交互;上层agents负责协调中间层agents之间的交互。给出了系统模型的仿真实验方法,最后建立了基于多agent的军事物流仿真模型,并通过系统模型的仿真运行,对系统模型的正确性进行了检验。 相似文献

We explore the impact of channel structure on the manufacturer, the distributer, the retailer and the entire supply chain by considering three different channel structures in radiance of with and without coordination. These structures include a traditional retail channel and two manufacturer direct channels with and without consistent pricing. By comparing the performance of the manufacturer, the distributer and the retailer, and the entire supply chain in three different supply chain structures, it is established analytically that, under some conditions, a dual channel can outperform a single retail channel; as a consequence, a coordination mechanism is developed that not only coordinates the dual channel but also outperforms the non-cooperative single retail channel. All the analytical results are further analysed through numerical examples. 相似文献

Discrete event simulation (DES) is a technique that is used by analysts to take informed decisions regarding an existing or proposed system of interest. DES models typically represent the processes associated with various business units. However, in the case of supply chains more than one business unit may need to be modelled as different organisations may be responsible for various supply chain operations such as manufacturing, transport and logistics, distribution, warehouse operations, etc. Organisations can be protective about their internal processes and can have concerns regarding data/information security and privacy. Thus it could be argued that creating a single DES supply chain model representing the various inter‐organisational processes is usually not an option since this will run counter to organisational privacy. Further, issues such as data transfer, model composability and execution speed may also make a single model approach problematic. A potential solution could be to create several distinct and well‐defined DES models, each modelling the processes associated with one specific supply chain business unit, linked together over the internet. We refer to this possible distributed approach as Distributed Supply Chain Simulation (DSCS). Although this approach holds great promise, there are technical barriers in using DSCS. The paper discusses the benefits and barriers of a distributed approach and then, using a healthcare DSCS, the technological feasibility is demonstrated. In conclusion, the paper argues that adopting a standardised approach to DSCS will remove a major barrier to its use. 相似文献

展示了古诺竞争模型中一个供应商和多个零售商的3 阶段博弈模型, 并证实了如果零售商能真实地分享预测信息, 则供应商往往会获利, 而零售商的利润将下降. 分享信息时零售商会有动机透露较少的需求预测, 这种信息失真现象是各方利用私人信息获取自身利益的结果. 如果供应商和零售商分享信息前, 能够就相对利润率或利润达成协议, 则信息共享的阻碍因素和扭曲信息的动机会消失, 零售商将如实地分享信息, 双方都能够从信息共享的行为中获利. 相似文献

This study considers a stylized supply chain model consisting of a dominant supplier and a buyer, in which the latter possesses superior knowledge of his private cost information. The supplier's imperfect knowledge about the buyer's cost is denoted by a subjective distribution. By assuming that the distribution is uniform, we first derive the explicit expressions of the optimal equilibrium outcomes of two contract formats offered by the supplier, the simple price‐only contract and sophisticated menu of contracts, respectively. Based on the optimal results, we continue to investigate how the supplier's expected profit varies with the level of information asymmetry, which is measured by the variance of the supplier's subjective distribution. Our findings indicate that the supplier's expected profits initially decrease and then increase as the supplier's knowledge of the buyer's cost becomes increasingly uncertain. That is, if the supplier could choose the level of information asymmetry, she would prefer a symmetric case (with the variance being zero) or a totally asymmetric case (with the variance being as high as possible). Numerical experiments demonstrate that our result still holds when we take into account such distributions as a truncated gamma and normal, and a fixed support of the distribution function instead of a moving support. 相似文献
