Abstract: According to previous researches, an investigation through small to mid-size construction contractors showed that 84% of construction contractors execute their projects in a multi-project environment. In a multi-project environment, scheduling problems with resource constraints are much more complicated than those in a single project. One of the most important factors that influence multi-project scheduling problems is resource allocation policy, depending on the types of resources, which can be defined by the way of resource acquisition and sharing behavior. This paper discusses resource allocation mechanism for construction multi-project scheduling issues, and then presents an optimization-based model to resolve resource allocation problems. This research developed a CP-based (Constraint Programming) model, which is capable of handling different optimization objectives such as minimizing total cost, overall project duration, subject to resource assignment combinations for each activity. Based on research results, the influence of different types of resource quantity on multi-project duration is discussed. Moreover, resource competitive behavior among all projects is recognized. It concludes that the effective increment of critical resources can reduce overall project duration. The major goal of this research is to find the relation among duration-cost-resource in a multi-project environment, and provide systematic information for construction parties when making resource allocation decisions.

Abstract: The project logistics indicators system of risk evaluation is established through analyzing the project logistics risk characteristics. Risk evaluation model is proposed based on matter-element theory.The project logistics risk、evaluation index and the characteristic value are taken as the matter-element. The logistics risk grade can be gained by calculating the risk coefficient of correlation, using subjective and objective combination weighting methods and the integrated risk correlation calculating in the end. An example is used to validate the proposed method. The results show this model can solve the problem of uncertainty index and the risk quantitative analysis then risk decision can be made.

Abstract: For improvement of operability and ensuring of reliability, the local technical guidelines for Safety Project for Primary and Secondary School Buildings in Yunnan Province was developed as complementary files for national standard of seismic appraisal of buildings, which was just replaced by a new version. The local guidelines were used in the investigation and appraisal for buildings safety project of primary and secondary school 2009, and led to good results. Executive summary of the investigation and appraisal was presented, existed weakness and improvement requirement were also proposed.

Abstract: With the increase in merger and acquisitions (M&A) activities, managers of bidder firms need to make informed decisions on quantifying the operational synergies in an M&A. This paper considers a stochastic variational inequality approach to quantifying the operational synergies in a horizontal M&A through the integration of a supply chain network, in which each firm is represented as a network of economic activities associated with manufacturing, distribution, and storage. Specifically, we seek to quantify the gains, if any, associated with M&A. The model is stochastic and sufficiently general to handle many decision-makers and their independent behaviors. This paper extends Nagurney (2009) in which the cost functions (including both the production function and the transaction function) and the pricing cost are deemed as stochastic. Quasi-Monte Carlo approximating and homogeneous interior-point methods are used to solve the stochastic problem. Numerical results are provided.

Abstract: The whole progress of construction project management from Low-carbon idea is studied in this paper. And we hope these research results make project manager agree on the low-carbon idea of the energy conservation mode and sustainable development mode. Then the future project products become the low-carbon products and become the sustainable development products.

Abstract: Project management calls for all kinds of resource factors, such as, manpower, equipment, technology and data, etc. It has been proved by practice that, manpower is the most important resource factor in project management. Thus, human resource management in project management seems especially important. For human resource management in project management, we should successful organizational programming and personnel recruitment,set up all kinds of rules,strengthen position training,facilitate communication among members, implemen performance management and effective incentive.

Abstract: This thesis discusses the development of Earned Value and introduces the concept of that value and the related indicators. The paper cites real applications and situations in which the method is adopted, analyzes the advantages and disadvantages of method, with the aim to explain its suitability in the management, and to offer suggestions as to the wide use of the method in project management.

Abstract: Construction enterprises are gradually developing into the middle force of business, which reflects a regional economic development. The paper analyzes seven indicators of construction enterprises in Inner Mongolia and collects three factors, which has a specific name and meaning, and sorts the performances of these construction enterprises according to scores so as to get levels of these enterprises. Then, the paper uses cluster analysis to analyze these enterprises to get a better understanding and take different measures to develop these enterprises.

Abstract: This thesis proposes a multi-project management method based on Gantt chart and network planning techniques in modern corporate multi-project management by analysing characteristics and status quo of corporate multi-project management and basing on features of multi-project management and Gantt chart and network planning techniques.

Abstract: Based on the value chain analysis of the real estate enterprises’ activities, this paper builds the real estate enterprises’ management maturity measure model, and provides the evaluation of the enterprises’ management maturity based on case study. The maturity measure model built in this paper contains three dimensions: management ability level, management organization and management activities. The model can simultaneously measure the overall management level of the real estate company, the management ability of every management department, as well as the management ability of related activities.
