本研究在探討多樓層倉儲系統中專用式儲位與垂直搬運設備之佈置規劃問題。和一般倉儲系統的儲位佈置問題不同在於，在儲位佈置方面，多樓層倉儲系統必須考慮垂直和水平移動相對的顯著性，因此需要同時考慮水平移動以及垂直移動的成本。在垂直搬運設備規劃方面，研究中考慮了垂直搬運設備的數量與位置對於成本結構的影響，並且同時考量垂直搬運設備的容量限制，雖然使得問題的複雜度提高，但卻更能接近實際倉儲佈置規劃之成本結構的考量。研究的目的是在最小化垂直搬運設備的建構成本以及產品搬運距離的相關總成本，同時決定產品專用儲位的配置、垂直搬運設備的數目與位置以及產品儲位對於每個垂直搬運設備的流量分配。

本研究首先建構多樓層專用式儲位與垂直搬運設備佈置問題的數學模式，模式中同時考慮到四組決策變數，分別為產品配置到儲位的變數、垂直搬運設備的數目與位置、產品儲位使用各個垂直搬運設備的流量分配變數。由於模式中成本結構的非線性程度相當高，使得目標函式變得相當複雜，因此在研究中針對多樓層倉儲系統的問題結構以及I/O點的相關位置，發展並證明出多個垂直搬運設備最佳位置的特性，並分析出水平與垂直移動成本比例大小的相關特性。

本研究根據垂直搬運設備最佳位置的特性，發展一個三階段之啟發式演算法，藉以有效率地求得最佳或近似最佳的儲位與垂直搬運設備的佈置。進而以演算實驗來驗證啟發式演算法的成效；在演算實驗中，並分析研究中的相關參數，得知儲位個數與I/O點相關位置對於啟發式演算法的演算效率有顯著的影響。實驗結果發現小樣本的求解效率遠比軟體高約數十倍，而且求解品質不分軒輊；在大樣本問題的求解時，則使用修正後的演算法，其求解效率或品質上均能表現良好，可以用來求解實際問題。
