在能源需求不斷增加的情況下，電費開支迅速成長。當我們觀察電費帳單的組成
時，會發現有幾種方法可以降低成本。本文討論了一種特殊計費模式的案例，基於
該模式建模，透過線性規劃進行求解，並將其應用於即時問題並進行一定的優化。
最後，我們在模擬中使用真實數據進行了實驗，並與其他兩種演算法進行了比較其
性能。

In the face of escalating energy demands, the expenses on electricity is growing
rapidly, when we take a closer examination of the composition of electricity bills,
there are ways for reducing the cost. This paper discusses a case with special billing
model, modeling a problem based on it, solving via linear programming, and applying
it to a real-time problem with some revision. At last, we carried out some experiments
in simulation environment with real-word data, and compare its performance
with two other algorithms.
