【摘要】：近些年來(lái),我國(guó)的科學(xué)技術(shù)高速發(fā)展,在高新技術(shù)的帶動(dòng)下,我國(guó)對(duì)大型建設(shè)工程項(xiàng)目的需求日漸提高,但大型建設(shè)工程項(xiàng)目由于其自身規(guī)模大、工程結(jié)構(gòu)與施工技術(shù)復(fù)雜、建設(shè)協(xié)作單位多、施工條件多變等特點(diǎn),使得在使用傳統(tǒng)管理方法時(shí)難以達(dá)到滿意的效果。為實(shí)現(xiàn)大型建設(shè)工程項(xiàng)目的管理目標(biāo),新技術(shù)和新方法的運(yùn)用是解決工程項(xiàng)目管理問(wèn)題的有效途徑,進(jìn)度目標(biāo)作為項(xiàng)目管理三大管理目標(biāo)之一,更是應(yīng)用的重點(diǎn)。由于分析和評(píng)價(jià)大型建設(shè)工程項(xiàng)目進(jìn)度的信息數(shù)量大且項(xiàng)目進(jìn)度管理信息隨工程所處階段同步變化,就使得進(jìn)度計(jì)劃的調(diào)整具有了顯著的動(dòng)態(tài)性和即時(shí)需求性。針對(duì)這一需求,本文以工程項(xiàng)目管理理論和自適應(yīng)控制技術(shù)為基礎(chǔ),對(duì)大型建設(shè)工程進(jìn)度計(jì)劃的自適應(yīng)調(diào)整問(wèn)題進(jìn)行了較為深入的研究。在這一研究中,開(kāi)始介紹了進(jìn)度的定義、內(nèi)容及特點(diǎn),研究了大型建設(shè)工程項(xiàng)目特點(diǎn)及其估計(jì)時(shí)間過(guò)長(zhǎng)和工期嚴(yán)重拖延的原因,據(jù)此引出建設(shè)項(xiàng)目進(jìn)度計(jì)劃動(dòng)態(tài)調(diào)整概念。接著,介紹了自適應(yīng)控制技術(shù)的定義,明確了自適應(yīng)控制具有穩(wěn)定性、動(dòng)態(tài)性及準(zhǔn)確性等特點(diǎn),明確自適應(yīng)控制本質(zhì)為反饋控制模式,著重介紹自適應(yīng)反饋控制原理,分析了自適應(yīng)反饋控制系統(tǒng)主要由比較模塊、控制模塊和檢測(cè)模塊構(gòu)成,并明確了自適應(yīng)反饋控制系統(tǒng)具體工作流程是由輸入經(jīng)比較器和控制器等原件再到輸出的系統(tǒng)主線路和由輸出、檢測(cè)模塊再到輸入的反饋回路構(gòu)成,整個(gè)過(guò)程持續(xù)不斷,直到系統(tǒng)內(nèi)偏差消失或被控對(duì)象狀態(tài)穩(wěn)定在期望狀態(tài)下。再次,進(jìn)行自適應(yīng)技術(shù)與大型建設(shè)工程進(jìn)度計(jì)劃問(wèn)題的相關(guān)性分析,明確了自適應(yīng)控制技術(shù)在解決大型建設(shè)工程項(xiàng)目進(jìn)度計(jì)劃問(wèn)題的可能性,在此基礎(chǔ)上,假設(shè)了自適應(yīng)控制技術(shù)在大型建設(shè)工程項(xiàng)目進(jìn)度計(jì)劃應(yīng)用的條件,并依據(jù)這些條件建立了大型建設(shè)工程項(xiàng)目自適應(yīng)調(diào)整規(guī)則,為之后建立大型建設(shè)工程項(xiàng)目進(jìn)度計(jì)劃自適應(yīng)調(diào)整系統(tǒng)建立基礎(chǔ)。最后,針對(duì)擬構(gòu)建的大型建設(shè)工程項(xiàng)目進(jìn)度計(jì)劃自適應(yīng)調(diào)整系統(tǒng)作目標(biāo)分析和需求分析,明確構(gòu)建系統(tǒng)目的和實(shí)現(xiàn)目的的功能側(cè)需求,在明確系統(tǒng)功能需求的基礎(chǔ)上提出進(jìn)度自適應(yīng)調(diào)整系統(tǒng)需要有數(shù)據(jù)接收模塊、數(shù)據(jù)處理模塊和數(shù)據(jù)調(diào)整模塊等三大核心功能模塊構(gòu)成,在此基礎(chǔ)上詳細(xì)分析了各功能模塊的工作原理及工作流程,并將三大功能模塊進(jìn)行結(jié)合,提出了工程項(xiàng)目進(jìn)度計(jì)劃自適應(yīng)調(diào)整系統(tǒng)的工作原理,據(jù)此構(gòu)建了大型建設(shè)工程項(xiàng)目進(jìn)度計(jì)劃自適應(yīng)調(diào)整系統(tǒng),并利用工程實(shí)際數(shù)據(jù)對(duì)其有效性進(jìn)行了驗(yàn)證。
[Abstract]:In recent years, with the rapid development of science and technology in our country, the demand for large-scale construction projects is increasing day by day under the impetus of high and new technology. However, because of its large scale, the structure and construction technology of large-scale construction projects are complex.It is difficult to achieve satisfactory results when using traditional management methods due to the characteristics of many cooperative units and variable construction conditions.In order to realize the management goal of large-scale construction project, the application of new technology and method is an effective way to solve the problem of project management. As one of the three management objectives of project management, progress goal is the key point of application.Due to the large amount of information of analyzing and evaluating the progress of large construction projects and the synchronous change of the information of project schedule management with the stage of the project, the adjustment of schedule plan has obvious dynamic and immediate demand.In order to meet this demand, based on the theory of project management and adaptive control technology, this paper makes a deep research on the adaptive adjustment of large-scale construction project schedule.In this study, the definition, content and characteristics of schedule are introduced, and the characteristics of large construction projects and the reasons for long estimated time and serious delay of construction period are studied, and then the concept of dynamic adjustment of construction project schedule is introduced.Then, the definition of adaptive control technology is introduced, the characteristics of adaptive control are defined, such as stability, dynamic and accuracy, the essence of adaptive control is the feedback control mode, and the principle of adaptive feedback control is emphasized.The adaptive feedback control system is mainly composed of comparison module, control module and detection module.The specific work flow of the adaptive feedback control system is made up of the main circuit from the input to the output by the comparator and controller, and the feedback circuit from the output, the detection module and the input feedback loop. The whole process is continuous.Until the deviation within the system disappears or the state of the controlled object is stabilized in the desired state.Thirdly, the correlation analysis between adaptive technology and progress plan of large-scale construction project is carried out, and the possibility of adaptive control technology in solving the problem of schedule planning of large-scale construction project is clarified, on the basis of which, the feasibility of adaptive control technology in solving the problem of schedule planning of large-scale construction project is clarified.The adaptive control technology is assumed to be applied to the schedule planning of large-scale construction projects. Based on these conditions, the adaptive adjustment rules for large-scale construction projects are established.The foundation of adaptive adjustment system for large-scale construction project schedule is established.Finally, the purpose analysis and requirement analysis are made for the adaptive adjustment system of schedule planning of large construction project to be constructed, and the functional side requirement of constructing system purpose and realizing purpose is defined.On the basis of defining the functional requirements of the system, it is put forward that the system needs three core functional modules: data receiving module, data processing module and data adjusting module.On this basis, the working principle and workflow of each functional module are analyzed in detail, and the working principle of the adaptive adjustment system of project schedule is put forward by combining the three functional modules.Based on this, the adaptive adjustment system of large-scale construction project schedule is constructed, and its validity is verified by the actual engineering data.
