【摘要】：生產調度能為企業(yè)帶來明顯的經濟效益,基于數(shù)學規(guī)劃的調度問題的建模與求解,是理論和應用研究的一個熱點問題。本論文以鋼鐵企業(yè)用氧調度為背景,研究多個可變負荷的空分裝置聯(lián)產調度問題。 本文研究工作主要包括以下三個方面： 1.現(xiàn)有的空分調度模型通常采用線性方程描述空分裝置中各產品的比例關系,與變負荷裝置中氧、氬、氮等產品的內在關系差別較大。因此本文引入變負荷空分裝置機理方程,建立單臺空分變負荷的非線性約束方程。 2.考慮到空分流程的復雜性及聯(lián)產調度中存在等價設備的情況,選擇資源任務網絡作為建模方法,用以描述整個系統(tǒng)中可使用的設備情況及物料流股的流動方向,避免遺漏方程。然后以某鋼鐵企業(yè)為背景,建立空分聯(lián)產變負荷調度模型。 3.通過人工調度仿真結果進行調度模型的參數(shù)估計,估算出管網氧氣流量與壓力關系式中的參數(shù)K。其次用仿真獲得的氮氣的產量與人工調度實際的氮氣產量進行對比,驗證模型中引入機理方程的準確性。最后求解以企業(yè)經濟效益最大為目標的聯(lián)產變負荷調度命題,分別以無放散,及放散量不受限制兩種約束條件進行求解,求解結果優(yōu)于人工調度,驗證調度模型的有效性。
[Abstract]:Production scheduling can bring obvious economic benefits to enterprises. Modeling and solving scheduling problems based on mathematical programming is a hot issue in theory and application research. In this paper, based on oxygen scheduling in iron and steel enterprises, the co-generation scheduling problem of multiple air separation units with variable load is studied. The research work of this paper mainly includes the following three aspects: 1. The existing air separation scheduling models usually use linear equations to describe the proportion of each product in the air separation unit, which is different from the internal relationship of oxygen, argon, nitrogen and other products in the variable load plant. Therefore, this paper introduces the mechanism equation of the air separation unit with variable load, and establishes the nonlinear constraint equation for the variable load of a single air separation unit. 2. Considering the complexity of the air separation process and the existence of equivalent equipment in the joint production scheduling, the resource task network is selected as the modeling method to describe the available equipment and the flow direction of the material flow unit in the whole system, and to avoid the omission of the equation. Then, based on the background of a certain iron and steel enterprise, the model of combined air separation and variable load dispatching is established. 3. 3. The parameters of the scheduling model are estimated by artificial scheduling simulation results, and the parameters K in the relationship between oxygen flow and pressure are estimated. Secondly, the simulation results of nitrogen production are compared with the actual nitrogen production by manual scheduling to verify the accuracy of the mechanism equation introduced in the model. Finally, the proposition of cogeneration variable load scheduling, which aims at the maximum economic benefit of the enterprise, is solved with two constraints: no release and no restriction. The result is superior to that of manual scheduling, which verifies the validity of the scheduling model.
