考量交通流量與暢通通行容量於物流網路靠度系統

在經濟與貿易的全球化、自由化的蓬勃發展下，企業必須思考如何降低營運成本並且滿足客戶的需求，以提高顧客的滿意度，這將是企業是否能夠永續發展及經營的關鍵議題。網路規劃已被廣泛應用在許多網路系統當中，其中物流網路的可靠度，代表物流服務能在指定的時間和條件完成的能力。物流網路的設計在供應鏈管理中屬於一個核心的問題之一，近年來許多研究學者把需求不確定性焦點放在多種商品的配送上，而本研究則是在道路流量隨機的情況下之針對單一商品物流網路可靠度進行探討。本研究所謂的道路流量隨機性，即是道路路徑流量並沒有明確的數值，而這也將影響企業在進行物流配送時的能否準時的將貨物送達至顧客手中，本研究透過模型建構以及演算法回應上述問題。研究結果顯示暢通可靠度即使低於預設值也不影響準時達交可靠度，最後所獲得之運輸成本對考不考慮可靠度無太大影響。

In a world with globalized economy and trade liberalization, companies need to consider how to reduce operating costs and meet customer needs to improve customer satisfaction. It will be the key issue whether enterprises can have sustainable development and operations. Network planning has been widely used in many web systems, where logistics network reliability, the ability to complete logistics services at a specified time and conditions is a key issue. The logistics network design is one of the core problems in supply chain management, under the circumstances of demand uncertainty on the distribution of a variety of goods. In this study, the road traffic randomness is the road traffic with no clear path, which will also affect the on-time delivery in logistics. A model was presented and a numerical example was illustrated. The results showed that the low smooth reliability does not affect the delivery reliability and cost of transportation.
