第五章 結論與建議

5.2 建議

目前尚有繼續探討之議題,期許可供未來相關研究之參考:

1. 目前路線集合未有任何刪除動作,若執行次數提升,對於求解時間產生多於負 荷,建議發展出動態之調整路線集合之機制,保留有效之路線使得求解效率提升。

2. 以原演算法模式延伸發展,可探討具有時間窗限制之 VRPPC,相信可以有不錯 之效果。因為在產生新路線中,具有時間窗限制之可行路線數量較少,可避免由 於過多路線而導致演算效率緩慢之情況。或是考慮多車種之情況,使得在實務之 應用上更具代表性。

3. 多加嘗試設定演算法中使用參數不同數值,期望加快求解效率,並在穩定求解品 質與速度上做權衡。

4. 將 Code 進行最佳化以進行測試,可以更短之執行時間藉以突顯本研究之成效,

甚至可使用較低階之程式語言撰寫,已獲得更佳執行時間。
