【摘要】：隨著綜合調(diào)度的研究，向著解決更加實(shí)用的問(wèn)題發(fā)展，已由單車間問(wèn)題轉(zhuǎn)向更復(fù)雜的多車間分布式調(diào)度。雖然國(guó)內(nèi)外對(duì)單車間調(diào)度和分布式調(diào)度有過(guò)大量研究，但分布式且針對(duì)綜合調(diào)度的成果較少。 針對(duì)如何在兩個(gè)對(duì)稱設(shè)備資源的車間上，有效分解復(fù)雜產(chǎn)品，并快速加工的綜合調(diào)度問(wèn)題，設(shè)計(jì)了基于擬關(guān)鍵路徑的兩車間綜合調(diào)度算法。為優(yōu)化兩車間并行能力，設(shè)計(jì)了預(yù)調(diào)度調(diào)控策略，縮短車間用時(shí)之差；為控制工序之間的遷移，以成串的形式出現(xiàn)的工序，整體進(jìn)行處理；由于叉狀工序，對(duì)控制遷移次數(shù)有影響，而緩沖工序，影響其緊后工序的開(kāi)始加工時(shí)間，設(shè)計(jì)調(diào)整策略，以解決上述工序分配，兼顧并行效果與遷移控制。 有效減少工序的遷移次數(shù)，是兩車間綜合調(diào)度算法具有高性能的保障，而且兩個(gè)車間設(shè)備資源不局限于對(duì)稱情況，還包含非對(duì)稱情況。為此，首次提出以部件整體為處理單位的思想，設(shè)計(jì)了不同設(shè)備兩車間綜合調(diào)度部件劃分算法：在部件為連通樹(shù)狀結(jié)構(gòu)的前提下，盡量使部件內(nèi)部工序使用的設(shè)備無(wú)重復(fù)且無(wú)對(duì)立情況。該算法在考慮對(duì)稱設(shè)備資源與非對(duì)稱設(shè)備資源同時(shí)，能有效地減少工序的遷移次數(shù)，使劃分過(guò)程便于操作，車間任務(wù)分配更合理，便于劃分完成后的完整調(diào)度。 針對(duì)在不同設(shè)備資源的兩車間有效分解復(fù)雜產(chǎn)品提高加工速度問(wèn)題，設(shè)計(jì)不同設(shè)備兩車間驅(qū)動(dòng)的部件匹配綜合調(diào)度算法。為減少遷移，設(shè)計(jì)部件劃分策略：采用不同設(shè)備兩車間綜合調(diào)度部件劃分算法，將產(chǎn)品工序劃分成相應(yīng)部件；為平衡負(fù)載，設(shè)計(jì)長(zhǎng)路徑部件車間驅(qū)動(dòng)匹配策略：先對(duì)部件路徑長(zhǎng)度最大的部件優(yōu)先進(jìn)行車間選擇，對(duì)其中非特殊部件匹配到已調(diào)度工序結(jié)束較早的車間；為充分利用空閑時(shí)間段，對(duì)可調(diào)度部件中的工序設(shè)計(jì)部件長(zhǎng)路徑工序空閑時(shí)間適應(yīng)調(diào)度策略。實(shí)例表明，該算法不僅減少工序遷移次數(shù)、控制負(fù)載平衡和縮短加工總時(shí)長(zhǎng)，，且算法復(fù)雜度不超過(guò)三次多項(xiàng)式。
[Abstract]:With the research of comprehensive scheduling , it has turned to more complex multi - shop distributed scheduling from single - workshop problem to solving more practical problems . Although there are many researches on single - shop scheduling and distributed scheduling at home and abroad , the distributed and integrated scheduling results are less . In order to optimize the parallel ability of the two workshops , the paper designs a two - shop comprehensive scheduling algorithm based on the quasi - critical path . In order to optimize the parallel ability of the two workshops , a pre - dispatching control strategy is designed to shorten the time difference between the workshops ; In order to reduce the migration times of the working procedure effectively , the two - workshop comprehensive scheduling algorithm has high performance , and the two workshop equipment resources are not limited to the symmetry , but also contain the asymmetric information . In order to reduce the migration and design component division strategy , the paper divides the product working procedure into corresponding parts by using two workshops integrated scheduling component transfer algorithm of different equipment . In order to reduce migration and design component division strategy : firstly , the parts with the largest length of part path are divided into corresponding parts ;
