【Abstract】 As schedule compilation involves many aspects，it is time consuming and effortto draw up a reliable network for large-scale complex hydraulic and hydropowerengineering. Aiming at the insufficiency during the preparation of network schedule,centered on the key technical issues in the network generation, analysis, evaluationand review in large-scale hydraulic and hydropower engineering, this paper carriedout in-depth research, the results obtained is of great significance for improving thereliability of hydraulic and hydropower project network schedule compilation,reducing the work intensity of the planning staff. The main research contents are asfollows:(1)Research on theory and methods on case-based and template-basedschedule assistant generation.For problems as inadequate experience utilization, the efficiency and accuracy isnot high, this paper conducted research on case-based and template-based scheduleassistant generation method, combined research status of network schedule assistedgeneration and actual progress of the project network planning process, functions suchthat retrieve case or template, combined schedule generation, assistant modificationand multiple ways of activity resource allocation are studied.(2)As problems that the formalization of combination compression schemeswhen there are multiple critical paths, a forthright and easy to programmingnetwork schedule duration cost optimization method is researched.Based on the basic principles in Schedule compression and linear programmingmethods, a combination and selection method(CSM) for network schedule time-costoptimization is presented, when there are many critical paths in a network schedule,CSM can combine the activities orderly in different critical paths, and select thequalified ones. Resolve problems which the formalization the combinationcompression schemes when there have multiple critical paths.(3)Through analysis of relationships among risk factors in the progress ofthe project plan, resource allocation, the managers’ attitude towards risks andrisk response measures, more realistic network schedule analysis and evaluationmethods are researched.Centered on the realistic process of project management and control, throughstudy and analysis of relationships among risk factors in the progress of the project plan, resource allocation, the managers’ attitude towards risks and risk responsemeasures, the controllability indicator of the activity duration of the network scheduleis presented, as the effects of countermeasures are different along with the differentoccurr time of risks, assistant analysis method based on duration controllability ofnetwork schedule was presented, and Monte Carlo simulation model based onconstruction influence factors is built.(4)Research on integrated network assistant generation, analysis, evaluationand review system in hydraulic and hydropower project.Based on the above theory and methods, utilizing case-based reasoning, expertsystems, database technology, object-oriented technology, computer simulation andvisualization technology, with actual demands and characteristics in engineeringpractice, integrated network assistant generation, analysis, evaluation and reviewsystem in hydraulic and hydropower project is proposed.Through the above study, the research achievements are as follows:(1) Case-based and template-based schedule assistant generation method arepresented, the method makes full use of the characteristics based reasoning andretrieval method of hydraulic and hydropower project.(2) Combination and Selection method for network Schedule time-costoptimization is presented based on the Linear-Programming, through the comparisonof cut-set method, the correctness and rationality of the method is proved.(3) The controllability indicator of the activity duration of the network schedule isproposed, and simulation evaluation method based on duration controllability ofnetwork schedule is presented.(4) Researched and developed synthetic integrated network schedule system forlarge-scale hydraulic and hydropower project, the system integrates functions thatnetwork schedule auxiliary generation, analysis, evaluation and review.更多还原
