In this paper, we study inventory share policies in an omni-channel supply network, to contribute to the circular economy (CE) concept. Lateral inventory share implementation provides flexibility and profitability in the supply chain by allowing inventory share between the same echelon locations in a network. Total holding costs and transportation costs can be reduced by lateral inventory share applications, which also contribute to decreased material usage for production over time, as well as reduced CO₂ emission released by transportation. Technological and Internet of Things (IoT) developments make it possible for companies to share their real-time information with each other for uninterrupted marketing experiences. With such a connected network, companies aim to increase their profitability and responsiveness to their customers. We explore a well-designed inventory share policy towards the CE concept under an (s, S) inventory control policy. We simulate several pre-defined share designs by Arena 16.0 commercial software and compare their performances in terms of cost, responsiveness, transportation frequency, inventory held, etc. The results show that, by the implementation of a well-designed lateral inventory share policy, an omni-channel network can benefit from decreased holding cost and transportation cost, contributing to the CE concept.

库存共享政策下面向循环经济的全渠道网络设计

在本文中，我们研究了全渠道供应网络中的库存共享策略，以促进循环经济（CE）的概念。横向库存共享的实现通过允许网络中同一梯队位置之间的库存共享，在供应链中提供了灵活性和获利能力。可以通过横向库存共享应用程序来减少总的持有成本和运输成本，这也有助于减少生产中的材料消耗，并减少CO _{2排放量。}运输释放的排放量。技术和物联网（IoT）的发展使公司可以彼此共享实时信息，从而获得不间断的营销体验。借助这样的互联网络，公司旨在提高其盈利能力和对客户的响应能力。我们在（s，S）库存控制政策。我们通过Arena 16.0商业软件模拟了几种预定义的份额设计，并比较了它们在成本，响应速度，运输频率，持有的库存等方面的性能。结果表明，通过实施设计良好的横向库存份额策略，全渠道网络可以从降低的持有成本和运输成本中受益，从而为CE概念做出了贡献。
