摘要
供应链是一典型的动态系统,链内各成员间供给与需求的关系随时间发生改变,同时,成员的目标也是随时间的变化而变化,如何协调系统中各成员之间的关系与利益是供应链管理中一复杂而重要的问题．为此,通过引入经济学中的均衡理论,以变分不等式为工具,研究一个由m个制造商和n个批发商所构成的具有库存的两阶段供应链的物流与价格动态均衡问题．给出了相应的均衡条件和经济解释,并建立了均衡问题的变分不等式模型,最后证明了变分不等式问题解的存在性与唯一性．
Supply chain is a typical dynamic system, in which the relationships between supply and demand among the partners and the goals of different partners are both time-dependent. In order to coordinate the relationships and benefits of the partners in supply chain management, based on the equilibrium theory in economics and variational inequality, the dynamic equilibrium of material flow and price with two echelons supply chain, which comprises m manufactures and n wholesalers and involves the inventories is investigated. The corresponding equilibrium condition and the economic interpretations are presented and the variational inequality model is established. Finally, the existence and uniqueness of solution of the variational inequality are proved.
