本研究主要探討二維平面的切割問題，此問題已被廣泛應用在面板業、玻璃業、布料業等產業，以有效使用原物料並提昇產品的競爭力。雖然過去有許多相關的文獻提出各種不同的方法來解決此問題，但所提出的方法求解品質不佳或求解速度慢。本研究運用確定性最佳化模式求解二維平面切割問題，可求得全域最佳解，本研究進一步將模式中的0-1變數減少，以加快求解時間，增加運算效率。本研究也探討不同規格原物料情況下的切割問題，運用數學模型求出最適生產規劃，進行多個原物料的切割，相較於過去只能進行單一原物料的切割，讓成本最小，原物料使用最精簡，可有效地協助企業創造利潤並提昇產品的競爭力，幾個案例也會提出來驗證所提出方法的正確性與實用性。

This study investigates the two-dimensional cutting stock problems. This issue has been widely addressed in the panel industry, glass industry, cloth industry and other industries, to effectively reduce the use of materials and enhance the competitiveness of the products. Although various approaches have been presented to solve this problem in many works, but they cannot guarantee to find a global solution or the solution process is too time-consuming. This study proposes a deterministic optimization model to solve the problem to find a global optimal solution. Moreover, this study reduces the binary variables of the original model to increase the computational efficiency. The proposed model also considers the cutting stock problem with different sizes of raw materials. Solving the formulated model, we can obtain the best production plan with lowest cost and optimize the utilization of the raw materials. The obtained results can help the company to create profits and enhance competitiveness of their products. Some cases are also presented to demonstrate the effectiveness and usefulness of the proposed method.
