【摘要】：大型水利水電工程往往具有規(guī)模大、受環(huán)境因素制約多且復(fù)雜的特點(diǎn)，制定切實(shí)可行的施工進(jìn)度計(jì)劃對(duì)于保證工程質(zhì)量，加快工程建設(shè)進(jìn)度，提高施工安全性具有重要的現(xiàn)實(shí)意義。然而，目前工程進(jìn)度網(wǎng)絡(luò)計(jì)劃編制還多依靠人工，雖然有P3（目前為P3e/c）、MS Project軟件輔助，其編制效率和質(zhì)量還是受到一定的制約。 自網(wǎng)絡(luò)計(jì)劃技術(shù)產(chǎn)生以來(lái)，網(wǎng)絡(luò)進(jìn)度計(jì)劃輔助生成問(wèn)題一直是工程界和學(xué)術(shù)界研究的重點(diǎn)問(wèn)題之一。從20世紀(jì)70年代至今，國(guó)內(nèi)外先后有學(xué)者提出了通過(guò)專家系統(tǒng)、工程案例推理、模板推理以及與CAD（計(jì)算機(jī)輔助設(shè)計(jì)）、IFC（工業(yè)基礎(chǔ)類）、BIM（建筑信息模型）結(jié)合的若干網(wǎng)絡(luò)進(jìn)度計(jì)劃自動(dòng)生成理論和方法，但這些方法大多沒(méi)有涉及復(fù)雜的水利水電工程，并且這些研究多是利用單一知識(shí)源來(lái)生成網(wǎng)絡(luò)計(jì)劃。 本文針對(duì)目前網(wǎng)絡(luò)進(jìn)度計(jì)劃輔助生成中存在的問(wèn)題，引入本體論的概念，研究將專家經(jīng)驗(yàn)、工程案例、模板、三維模型等多知識(shí)源中的知識(shí)進(jìn)行有機(jī)地融合，提出了一套基于多知識(shí)源網(wǎng)絡(luò)進(jìn)度計(jì)劃輔助生成方法。論文中開(kāi)展了如下幾個(gè)方面的工作： （1）針對(duì)大型水利水電進(jìn)度計(jì)劃輔助生成過(guò)程中的各種知識(shí)源的特征進(jìn)行研究，分析易于多源知識(shí)融合的結(jié)構(gòu)化知識(shí)組織形式和組織機(jī)制。 （2）針對(duì)三維模型中所隱含的大量的建筑構(gòu)件的空間信息和工程量等進(jìn)度計(jì)劃編制所需要的信息進(jìn)行知識(shí)挖掘途徑和方法研究。 （3）通過(guò)對(duì)大型水利水電工程施工過(guò)程的系統(tǒng)研究和分析，針對(duì)施工工序之間邏輯關(guān)系的確立，研究適用于水利工程的推理規(guī)則知識(shí)表達(dá)體系。 （4）通過(guò)借助本體論有關(guān)概念和研究，采用面向?qū)ο蟮睦砟睿芯炕诒倔w論的多源知識(shí)融合輔助生成工程網(wǎng)絡(luò)進(jìn)度計(jì)劃的基本機(jī)制。
[Abstract]:Large-scale water conservancy and hydropower projects often have the characteristics of large scale, many and complex constraints by environmental factors. To ensure the quality of the project and speed up the construction progress, it is necessary to draw up feasible construction schedule. It is of great practical significance to improve the safety of construction. However, at present, the network planning of engineering progress still depends on manual work, although it is assisted by P3e / C / C / MS Project software, its efficiency and quality are restricted to a certain extent. Since the emergence of network planning technology, the problem of auxiliary generation of network schedule planning has been one of the key issues in engineering and academic circles. From the 1970s to the present, some scholars at home and abroad have put forward the theory of engineering case reasoning through expert system. Formwork reasoning and several network schedule automatic generation theories and methods combined with CAD (computer aided Design) (CAD) / IFC (Building Information Model), but most of these methods do not involve complex water and hydropower projects. And most of these studies use a single knowledge source to generate network plans. In this paper, aiming at the problems existing in the network schedule auxiliary generation, this paper introduces the concept of ontology, and studies the organic fusion of knowledge from expert experience, engineering cases, templates, 3D models, and so on. In this paper, a method of scheduling aided generation based on multi-knowledge source network is proposed. In this paper, the following aspects of work are carried out: The main contents are as follows: 1) the characteristics of various knowledge sources in the auxiliary generation process of large-scale water conservancy and hydropower schedule planning are studied and the structured knowledge organization forms and organization mechanisms which are easy to integrate multi-source knowledge are analyzed. 2) knowledge mining approaches and methods are studied for the spatial information of a large number of building components and the information needed for the preparation of progress plans such as engineering quantities, which are implicit in the three-dimensional model. 3) through the systematic research and analysis of the construction process of large-scale water conservancy and hydropower projects, and in view of the establishment of logical relations between construction processes, the knowledge expression system of inference rules suitable for hydraulic engineering is studied. 4) the basic mechanism of multi-source knowledge fusion based on ontology to assist the generation of engineering network schedule is studied by means of ontology related concepts and research, and the object-oriented concept is adopted.
