本研究探討以信用支付和動態折扣計劃為支付方案的供應鏈網路設計。動態折扣是擴展信用交易計劃於供應鏈金融的策略之一。藉此策略，供應商將向分銷中心提供一個信用期限，如果分銷中心在信用期限的到期日之前向供應商付款，則折扣將有效。動態折扣具有許多優點，例如對資產負債表沒有負面影響以及對買賣雙方而言是真正的雙贏解決方案。本研究考慮了貨幣的時間價值，在分析中包括了現金流量折現。這項研究的關鍵決策是配送中心的補貨週期，配送中心的售價以及配送中心的影響範圍，以讓總利潤的現值最大化。首先，採用連續概似法來建立問題的數學模型。接下來，建立了基於非線性最佳化的算法來解決該問題。此外，提供了一個數值示例來介紹所提出的模型和解決方案之方法。最後，對幾個成本要素進行敏感度分析，以說明每個成本要素對總利潤現值的影響。透過敏感度分析，可以知道價格效應參數和單位成本對總利潤的現值影響最大。結果可應用於管理模式之觀點。

This research studies a supply chain network design under credit payment and dynamic discounting program as the payment scheme. Dynamic discounting is one of the supply chain finance policy that extends the trade credit scenario. Using this policy, the supplier will provide a credit period to the distributor center and a discount will be applied if the distribution center pays the supplier before the due date of the credit period. Dynamic discounting has several benefits such as no negative impact on the balance sheet and the true win-win solution for both buyer and seller. Besides, this research considers the time value of money, hence a discounted cash flow is included in the analysis. The key decisions of this research are the distribution center’s replenishment cycle, the distribution center’s selling price, and the distribution center’s influence area that maximizes the present value of total profit. First, a Continuous Approximation approach is applied to formulate a mathematical model of the problems. Next, an algorithm based on non-linear optimization is established to solve the problem. Furthermore, a numerical example is provided to present the proposed model and solution approach. Finally, a sensitivity analysis on several cost elements is presented to illustrate the effect of each cost element on the present value of total profit. Through sensitivity analysis, it is known that the price effect parameter and unit cost have the most significant effect on the present value of total profit. The results can be used for managerial insights.
