Amidst the rising global recognition of sustainability and the United Nations' sustainable development goals, enhancing the sustainability of the supply chain while properly distributing orders has become a key point. In contrast to the previous research, this research involves supplier sustainability in reliability evaluation and proposes a new algorithm for computing reliability. In the constructed supply chain network, a node represents a supplier, assembly plant, or customer, and an arc connecting the nodes. For each arc, it has a carrier whose available carrying capacity for demand transmission. The capacity of each carrier, represented by the available delivery containers, should not be deterministic as they may be partially reserved by other customers. Under these conditions, such a supply chain network is regarded as a stochastic supply chain network (SSCN). The reliability for an SSCN is defined as the probability that the SSCN can successfully transport a specific amount of goods to a customer under supplier sustainability level, supplier production capacity, and budget. Reliability is also regarded as a performance indicator for supply chain capability when managers makes decisions under supplier sustainability consideration.

在全球对可持续发展的认识不断提高以及联合国可持续发展目标的背景下，在合理分配订单的同时增强供应链的可持续性已成为关键。与以往的研究不同，本研究将供应商可持续性纳入可靠性评估，并提出了一种新的可靠性计算算法。在构建的供应链网络中，节点代表供应商、装配厂或客户，以及连接节点的弧。对于每个弧，它都有一个载波，其可用承载能力用于需求传输。每个承运人的运力（由可用的交付集装箱表示）不应是确定性的，因为它们可能被其他客户部分保留。在这些条件下，这样的供应链网络被视为随机供应链网络（SSCN）。 SSCN 的可靠性定义为在供应商可持续性水平、供应商生产能力和预算下，SSCN 能够成功地将特定数量的货物运输给客户的概率。当管理者在考虑供应商可持续性的情况下做出决策时，可靠性也被视为供应链能力的绩效指标。
