Comprehensive Optimization Study On The Project Planning Of Jilin-Caoshi Highway

Construction project's general objective is to make the progress of the shortest, least expensive and best quality, the three objectives of management are not isolated, but interrelated body of contradictory unity of opposites. The quality requirements of the higher costs will be a corresponding increase in and construction progress will be slower. Speed up the construction schedule, construction will increase the direct costs, quality levels will be reduced.From domestic and foreign construction projects on the management of the status quo and development trend can be seen that our project management units in the implementation of specific project management process, we must consider how the arrangements for the scientific progress of construction plans, a reasonable distribution of resources and quality assurance programs , timely information on the progress of construction, cost, quality, resources and other information so that progress of the project cost, quality and resources into consideration, the best possible arrangement. In this paper, through a combination of grass Jilin City Expressway to the tunnel project Hill of the sleeping cow example of the optimization of the project plan to achieve project progress, costs and optimize resource planning and coordination of integrated management.Heads of the progress, costs and optimize resource planning and coordination of integrated management. In this paper, a comprehensive project plan is optimized to ensure the quality of the project under the premise of the project through the project, cost and resources for effective control of the three indicators, with a view to improve project efficiency and rational use of resources, cost-saving purposes. In this paper, grass Jilin City Expressway to the project plan for the study, research project on the use of optimization on the highway tunnel project to optimize and ensure the progress, cost, resource optimization, better project plans to guide project practice. A comprehensive project plan is based on the Project Network optimization plan to achieve the optimization. Optimization of network planning project is bound by certain conditions, in accordance with the established objectives of the ongoing network planning inspection, evaluation, adjustment and improve the process. Program to measure the merits of a plan should be comprehensive evaluation of its technical and economic indicators, including duration, cost, resource consumption, such as, but not yet a comprehensive techno-economic indicators reflect the integrated mathematical model for evaluating the optimal scheme for program based on specific conditions can only be based on optimization of a single indicator. For a particular project, the time to optimize the conditions of limited resources, the shortest period; the cost of the optimum conditions for the limited period, the lowest cost; resources to optimize the conditions for limited duration, resource balance.This article first analyzes the impact of the project a major factor in planning, the initial progress of the preparation of project plans. The beginning of the planning stage of the project to carry out project work using WBS structure decomposition, all the work to determine the logical relationship between the use of activity duration estimate (PERT) techniques to estimate the project time, Technology for the use of network planning project schedule estimation during the appropriate resources, the generation of the network of the project plans to use such information, the application of optimization theory and methods for the establishment of project - the cost optimization model, the initial network of the project construction plan - Optimization of the formation of a number of construction costs - the cost optimization program, based on this method using the minimum variance project resource leveling optimization fixed. As a result of the construction project, costs and resources are the mutual influence and mutual constraints, the shortest duration, lowest cost and resource use of the most balanced of the three objectives are often contradictory, so that the best three at the same time it is done in most cases not. In the practice of engineering projects, project managers often want to optimize the network to achieve the project plan, cost and resource consumption of the overall best, of course, this is the best overall trade-off between each other after the results.This paper presents a number of factors of 22 projects to optimize the method, the application of these methods only consider the case of a single factor, in a period when the cost of optimizing resources, factors not taken into consideration. In order to always be duration, cost and resources as a whole, three factors to consider the issue, we must first identify period optimization, resource optimization, cost optimization and the links between the three.The next study in this article is to consider the project under the premise of optimizing, and always will be duration, cost and resources to consider three factors, according to the optimization of a specific target to generate the optimized network plan. Through analysis is not difficult to find, regardless of period optimization, cost optimization or resource optimization, all through the project to adjust the relevant parameters to achieve, and used to adjust the parameters of the main work is the start time and duration.The work of a different start time and duration will produce different schedule of programs that also corresponds to a different period, the cost and resource use. When carrying out optimization projects, is to identify goals that will enable optimizing the program to achieve optimal integrated.In this paper, the work of learning to use the experience of network planning techniques, see a great deal of relevant material at home and abroad, in a profound grasp of web-based technology based on the plan, first of all levels from the analysis and the analysis point of view, to explore and establish an integrated network planning optimization system the system at the same time period - the cost and duration of the optimization of resources, has been optimized a series of project proposals, Secondly, the use of AHP to the level of analysis; in accordance with the nature of the problem and to achieve the overall objective of the problem is decomposed into the composition of different factors, and in accordance with the relationship between these factors and its relationship to factors gathered by the combination of different levels, the project plan as a target layer, will have an impact on the construction project, cost, resources and the quality factor as a criterion level, will be optimized as part of the program options layer, forming a multi-level analysis of the structural model, When the build-level analysis model, the calculated factors within each level of the previous level for the relative importance of relevant factors (weight). Group of Experts on the evaluation factors based on specific indicators and field values of the individual subjective evaluation after comprehensive analysis of the factors one by one between the indicator 22 on the comparison carried out to determine, 9 According to this scale to judge the results to quantify the comparison in order to determine the formation of matrix, selection of project options to sort and consistency of single-level testing; Finally, after the completion of the level of a single sort order for the total level of optimization program order to compare the advantages and disadvantages to elect the best program.In this paper, examples of project analysis, the use of a large number of charts with the text that has been the result of full, effective solution to the conflict between the target and further explore and validate the method-level analysis of decision-making should be in the feasibility of specific and practical significance. The project plans to solve the optimization of network integrated multi-objective optimization problem of optimization and program. The establishment of a network planning project-level analysis of the model factors.Learn at home and abroad through the optimization of network planning theory advanced thinking and technology, combined with systems analysis, project plan to establish a comprehensive model to optimize the level of analysis, optimization of the system construction of a strong, cost, resources, coordination between the search for short period and low-cost, resource-balanced program of integrated optimal. Project on the impact of various factors to achieve the objective of the existence of mutual contradictions and conflicts of various subsystems of a complex system composed of an important degree of measurement and optimization, selected the best programs to reflect the investors, the construction unit of the project general requirements, reflecting its overall effectiveness.The level of analysis from the point of view, in the overall optimization of network planning analysis conducted on the basis of project impact the calculation of weight factors, the level of ideological and theoretical analysis.
