本文探討現有廠商在產品一項商品產生後，在既有的出貨通道下潛在運輸業者在選擇進入或退出的情形。此外，貨物運輸業者與顧客間的滿意度也在討論中。本文最先討論廠商在現有出貨管道包括實體店面與網路宅配下，潛在的運輸業者想要進入其運銷通路下在阻絕理論下可能進入或退出的情形。基於上述觀點，本文以數學模式有三：一、建構廠商在付給出貨運輸業者後的最佳營利成本；二計算現有店面與網路宅配業者的最小運輸成本；三、前在運輸業者選擇在進入運輸體系所需考慮的最小邊際收益為何。此外，在滿意度方面，本文以經濟學供應-需求的觀點建立另一個模式，亦即建立在實體店面與網路運輸下顧客的滿意度與信任度的關係，經計算證明當顧客的信任度等於滿意度時會有最佳解釋。 This paper discusses the commercial product after producing under the existing shipping channel in the transport sector in their choice of money into or out of the situation. In addition, goods transport operators and customer satisfaction are among the discussion. First, the existing shipping companies was discussed in this article, including physical stores and Internet pipeline delivery, the potential transporters going into its distribution channel in the block under the theory that might enter or exit the situation. Based on these ideas, there are three mathematical models: First, the construction companies pay shipping transporters in the best profit after the cost; second, computing network of existing stores and delivery companies with minimum transportation costs; third, prior to the transport industry to choose into the transportation system in the minimum margins required to consider. In addition, With regards to satisfaction, the paper has supply- demand point in economics to establish another model, which is built on the physical store and transport networks and customer satisfaction under the trust relationship, the calculation proves that when the customer's trust satisfaction, it will be equal to the optimal solution.
