Study On The Value-added Mechanism And Key Technologies Of Construction Programme Management

With rapid development of our national economy and acceleration of urbanization process, the total investment in the whole society fixed assets is increasing year by year, and large-scale projects are becoming more and more. With the characteristics of long construction period, complicated technology, lots of participation units, and difficult to organize and coordinate, these projects always appear in the form of groups. The uncertainty of realizing the three major objectives is increased due to the complexity and variability of programme internal structure, which makes higher requirement on project management level at the same time. For construction enterprise, how to effectively manage multiple related projects is an important problem to be solved. In general, the traditional project management methods put emphasis on achieving the goals of individual project, and pay little attention on organizational development strategy, that is difficult to meet the needs of proramme running. So it is of important theoretical value and practical significance to carry out research on construction programme management.This dissertation is dedicated to solve the prominent questions existing in the process of construction programme management. On one hand, the dissertation provides a viable action roadmap for construction enterprise to carry out the programme management work, which is of help to improve the operation mode, promote the organization’s ability to achieve strategic goals and market competitiveness, make construction enterprise develop in a sustainable, rapid and healthy way. On the other hand, the dissertation offers new management ideas and scientific decision-making methods to programme managers, that can help them standardize the management behavior, improve the programme management level, and realize the transformation of construction programme management from extensive to meticulous and intensive style. The research contents and main achivements of this dissertation are as follows:(1) Considering the influence factors such as the value of the project itself, the matching degree between project and proposed programme, the related effects among projects synthetically, a set of evaluation index system on project selection of construction programme is designed, which can fully reflects the adaptability and priority from the selected project to construction programme. In view of the fuzziness and randomness existing in the evaluation process of project selection, the cloud model in the field of artificial intelligence is introduced into the project selection problem, and the evaluation factor level is quantified by means of the knowledge expression and single rule uncertainty reasoning of cloud model, so as to realize effective transformation between qualitative concept and its quantitative numerical representation. The evaluation results can provide reference basis for constuction enterprise to select out the most appropriate multiple projects to constitute programme.(2) Based on the research perspective of value net, the collaborative management model on value-added realization of programme value net is constructed, which cover three collaborative modules, seven collaborative functions and two support platforms. The value-added mechanism of construction programme management is revealed. The value-added points of construction programme management are designed, and then the support elements which lead the programme value net to gain additional value are put forward, mainly including setting up reasonable programme management organization structure and establishing information sharing platform for programme management.(3) In order to realize the comprehensive balance optimization among the total duration, total cost and the overall quality of construction programme, the nonlinear relationship between duration and cost, duration and quality of construction project is analyzed firstly, and then the resource optimal allocation model of construction programme is constructed based on multi-attribute utility theory, in which the objective function and constraint conditions are discussed. As an advanced bionic optimization algorithm, particle swarm algorithm is introduced into the project resource optimal allocation problem of construction enterprise. The flight speed and location of particle swarm is constantly adjusted and updated to iteratively search for the optimal solution. It is known that the efficiency and precision of model solution are improved. Case analysis shows that using particle swarm algorithm can quickly and efficiently make out the shared resource quantity that distributed to every construction project and the duration of every engineering activity.(4) Combined with the risk evaluation indexes and classification standard of construction programme, the unascertained measurement model of programme risk is set up. In this model, the single index measurement matrix of programme risk is constructed by unascertained measurement function firstly, and then the weight coefficient of each evaluation index is determined on basis of combination weighting method integrated by expert scoring method and variation coefficient method. Furthermore, the multi-index comprehensive measure vector of programme risk can be worked out. Finally, the programme risk grade is judged in accordance with credible recognition rules, and radar figure is drawn to display the risk assessment results clearly and intuitively. The research results can offer certain reference basis for construction programme management decision-makers to take risk coping strategies and control measures.(5) Taking the basic thought of balanced score card for reference, the performance appraisal index system of construction programme management is established from five dimensions, including not only finance, customer, internal operation process, learning and innovation, but also social responsibility. There are twelve performance evaluation indicators in total. In view of the problem existing in the traditional TOPSIS model that the evaluation object may be both close to the positive ideal solution and the negative ideal solution, an improved TOPSIS method is put forward. Instead of Euclidean distance, the vertical distance between the evaluation object and positive ideal solution is taken to prioritize the performance of construction programme management, so that the implementation effect of programme management can be objectively measured and compared. The research results provide a new idea and approach for the performance appraisal of construction programme management.(6) The programme management maturity model, which is suitable for our national conditions, is established from the perspective of maturity levels and key areas. Moreover, the maturity evaluation method of construction programme management is proposed on basis of extenics theory. The correlation degree of each index relative to the evaluation grade is calculated through the design of correlation function and matter element transformation, then the method of rank correlation analysis is introduced to determine the weight coefficient of each evaluation index, at last the maturity level of construction programme management can be measured and compared comprehensively. The research results provide guidance for the ability of construction programme management to improve and promote.
