We put forward the graphical theory model of jsp, and analyze the cause of unfeasible scheduling and its characteristic, then educe the sufficient and necessary condition that a feasible scheduling solution requires 本文通過(guò)作業(yè)車間調(diào)度問(wèn)題數(shù)學(xué)模型的圖論形式,深人分析了產(chǎn)生不可行調(diào)度的原因及其特徵,得出了一個(gè)可行調(diào)度的充要條件。
The paper using vc + + as tool of programming based win98 os ( operate system ) develops a set of application software in which it has succeed in partition thermal system into modules . the way of building model of the rmal system is what connects all kinds of modules into network graphics, then analyze and compute by the way of graphical theory . at last using the software can successfully realize thermal economical performance analysis and compute of thermal system that dynamic set up 本文采用vc++作為編程工具,在win98操作系統(tǒng)下開(kāi)發(fā)出一個(gè)應(yīng)用軟件,在該軟件中,成功的將熱力系統(tǒng)進(jìn)行了模塊劃分,使用面向?qū)ο蟮乃枷?,將熱力系統(tǒng)中每一個(gè)設(shè)備作為一個(gè)模塊,而熱力系統(tǒng)模型的建立,則是使用這些模塊,將它們相互連接起來(lái),形成網(wǎng)絡(luò)圖,然后使用圖論的方法,對(duì)其進(jìn)行研究、計(jì)算,最終成功的對(duì)動(dòng)態(tài)組建的熱力系統(tǒng)進(jìn)行熱經(jīng)濟(jì)性分析、計(jì)算。
The paper presents a distribution analysis software platform which is developed combining computer graphical theory and oop ( object-oriented programming ) . the platform includes three modules, the graphics module, the database module and the computation module . the graphical module can draw the key diagram of power system; the database module can save, browse and edit the data of power systems; the computation module can compute the power flow 本文運(yùn)用面向?qū)ο蟮某绦蛟O(shè)計(jì)方法結(jié)合計(jì)算機(jī)圖形學(xué)的知識(shí),開(kāi)發(fā)了一套可視化配電網(wǎng)分析軟件平臺(tái),它包括用于繪制電力系統(tǒng)結(jié)線圖的圖形模塊、用于保存、瀏覽、修改電網(wǎng)數(shù)據(jù)信息的數(shù)據(jù)庫(kù)模塊和進(jìn)行配電網(wǎng)潮流計(jì)算的計(jì)算模塊。
To overcome the knowledge representation limitations of the traditional signed digraph model based expert systems for hazard and operability analysis, a novel layered digraph model for automating process hazard and operability analysis is proposed based on the graphical theory by decoupling the two dimensional signed digraph models in the three dimensional space 摘要為克服傳統(tǒng)的基于有向圖模型的危險(xiǎn)和可操作性分析專家系統(tǒng)在知識(shí)表達(dá)方面的局限性,通過(guò)將二維的有向圖模型在三維空間的解耦,采用圖論的方法,提出了一個(gè)可以用于危險(xiǎn)和可操作性分析自動(dòng)化的有向架模型。
