【摘要】：如果一個承包商要承擔(m32)個帶有權(quán)重和完工截至日期的工程項目,則存在以最小總加權(quán)誤工數(shù)為目標的工程項目排序優(yōu)化問題。文章首先通過一些符號和參數(shù),建立了該問題的一個不確定模型。然后,基于不確定理論,通過假設(shè)每個工程項目的處理時間是一個帶有不確定分布的不確定變量,由不確定變量的期望計算公式,將該不確定模型轉(zhuǎn)化為一個確定的模型。再次,給出了該確定模型一個新性質(zhì),并且由這個性質(zhì)設(shè)計了一種該模型解的算法,稱為DWE算法。最后,通過一個數(shù)值例子檢驗了該模型和算法的有效性。
[Abstract]:If a contractor is required to undertake (m32) projects with weights and completion deadlines, there is a scheduling optimization problem with the goal of minimum total weighted delay. Firstly, an uncertain model of the problem is established by some symbols and parameters. Then, based on the uncertainty theory, the uncertain model is transformed into a definite model by assuming that the processing time of each project is an uncertain variable with uncertain distribution. Thirdly, a new property of the deterministic model is given, and an algorithm for the solution of the model is designed by this property, which is called DWE algorithm. Finally, a numerical example is given to verify the validity of the model and algorithm.
