PREFACE

隨著客戶需求的不斷提高，多項目調(diào)度往往處于不確定環(huán)境下，導(dǎo)致實際調(diào)度方案不能完全按照基準(zhǔn)調(diào)度方案執(zhí)行或需重新安排調(diào)度計劃。不確定環(huán)境下的多項目調(diào)度問題需要充分考慮調(diào)度環(huán)境中的不確定性因素，如天氣原因造成的工期延誤或設(shè)備故障造成的停工等，而這種不確定往往是不可避免且無法預(yù)測的。因此，不確定環(huán)境下的多項目調(diào)度問題的研究有重要的理論價值與實際意義。針對多項目調(diào)度問題中各類不確定因素擾動初始調(diào)度計劃等問題展開研究，可恢復(fù)或避免擾動對多項目調(diào)度計劃的影響，以確保多項目順利完工。

項目執(zhí)行過程中存在諸多不確定性，對于多項目調(diào)度而言，由于任務(wù)數(shù)量龐大，涉及跨組織的資源調(diào)度，故而不確定環(huán)境下的多項目調(diào)度問題具有復(fù)雜性和不確定性等特征，增加了調(diào)度計劃的制訂難度，從而為多項目調(diào)度的管理帶來了困難和挑戰(zhàn)。因此，針對不確定環(huán)境下的多項目調(diào)度問題，如何在基準(zhǔn)調(diào)度計劃制訂階段考慮調(diào)度過程中存在的不確定因素，合理優(yōu)化項目結(jié)構(gòu)，制訂符合客戶動態(tài)需求的調(diào)度方案，已成為項目調(diào)度領(lǐng)域的研究熱點和前沿課題。

作者長期從事項目調(diào)度和網(wǎng)絡(luò)優(yōu)化等課題的研究，跟蹤國內(nèi)外的研究動態(tài)，本書是作者多年研究的總結(jié)，同時也吸取了國內(nèi)外的最新研究成果。本書以不確定環(huán)境下的多項目調(diào)度優(yōu)化問題為研究對象，探索動態(tài)客戶需求與項目任務(wù)調(diào)度的最佳配置方式。為此，搭建多項目動態(tài)調(diào)度的研究框架，構(gòu)建多項目動態(tài)調(diào)度優(yōu)化模型，從系統(tǒng)和全局視角研究不確定環(huán)境下的多項目動態(tài)調(diào)度優(yōu)化問題，豐富了多項目調(diào)度的研究方法，以期為不確定環(huán)境下的多項目動態(tài)調(diào)度問題提供理論與方法上的指導(dǎo)。

全書共7章。第1章介紹了不確定環(huán)境下多項目動態(tài)調(diào)度優(yōu)化問題理論與方法研究的背景和基本研究內(nèi)容。第2章主要分析不確定環(huán)境下多項目調(diào)度的基本屬性及國內(nèi)外研究現(xiàn)狀。第3章針對不確定環(huán)境下多項目調(diào)度的工期不確定問題展開研究，構(gòu)建不確定環(huán)境下的多項目調(diào)度工期-魯棒性均衡優(yōu)化模型，鑒于問題的復(fù)雜性，設(shè)計多級遺傳算法求解此問題。第4章深入分析不確定因素對多項目調(diào)度內(nèi)部資源使用率的影響，按照活動的可執(zhí)行性將其拆分為若干子活動，并執(zhí)行非搶占式執(zhí)行模式，在提高多項目調(diào)度資源利用率的基礎(chǔ)上，降低不確定因素對多項目調(diào)度系統(tǒng)的影響。以工期-成本-質(zhì)量-魯棒性為優(yōu)化目標(biāo)，利用效用函數(shù)建立多目標(biāo)均衡優(yōu)化模型，并設(shè)計云遺傳算法對問題進(jìn)行求解。第5章闡釋了不確定因素對工期、客戶滿意度、成本和資源可用量的影響，構(gòu)建面向多干擾的多項目調(diào)度模型，并設(shè)計雙種群遺傳算法求解問題模型。第6章介紹了多項目前攝性調(diào)度問題，并建立不確定環(huán)境下多項目前攝性調(diào)度模型，結(jié)合模型的特點設(shè)計遺傳模擬退火算法求解此問題。第7章介紹了多項目調(diào)度的未來發(fā)展趨勢。
