Abstract:

The distribution of profits in the VMI & TPL mode is directly related to the enthusiasms of all participants and the implementation effectiveness of the VMI & TPL mode. However, in the academic circles, limited attention has been paid to this issue and only a few studies have been conducted on the downstream of supply chain. In this paper, by taking into consideration the VMI & TPL mode and the parameters of supply chain, the upstream section is addressed and economic models are developed. Based on these models, the profit distribution mechanism is constructed according to the basic logic of the maximum entropy method whose basic premise is that all enterprises bear equal risks, which is not fully fit for the physical truth. Therefore, the profit distribution mechanism is modified and improved by the vertical projection method combining with an idiographic example test. The results indicate that the modified mechanism can compensate for the risk of the enterprise, and the profits created in the VMI & TPL mode at the upstream section are reasonably distributed among participants. Thus, a win-win goal can be achieved. In reality, this mechanism can be implemented by an income sharing contract constituted by all partners before the implementation of the VMI & TPL mode.

摘要：

实施VMI&TPL模式后如何分配利益直接关系到各参与者的积极性及VMI&TPL模式的实施效果，学术界对此问题关注有限，仅有的几项研究通常立足于供应链下游段展开。选取供应链上游段为研究对象，充分考虑实施VMI&TPL模式前后供应链参数的变化，建立经济效果模型。利用最大熵值法构建利益分配机制，考虑到该方法的基本前提是各企业承担均等风险，与实际情况存在偏差，利用正交投影法对所构建的机制进一步修正与完善，并通过算例进行验证。结果表明：修正后的机制能够对企业承担的风险做出补偿，使得由于实施供应链上游段VMI&TPL模式而产生的利益在各参与者之间合理分配，实现了各方共赢。在实际操作中，该机制可通过各参与者在实施供应链上游段VMI&TPL模式前共同制定利益分享契约而实现。
