Based on the research of the concept and structure of project complexity, the Construction System Complexity Concept Model (CSCCM) is built, considering the characters of construction project. In this paper, the behavior of the construction system is described in six angles of view, including engineering technology, project stakeholders’ organization structure, engineering task, engineering information,...
The high capability of project management is becoming the core power of the project-oriented corporation in more and more extent. This paper introduces the concept of Project Management Maturity, studies the evaluation indices of project management maturity for project-oriented organizations and finally sets up index system. In order to overcome the defect of other methods, neural network is applied...
Whether the key construction projects' progress is ongoing expectably or not will have important influence on the economic development. Aiming at the supervisors'(Microscopic level) insufficiency of the ability in grasping the project progress deviation, based on the balance theory, using the modern computer technology, utilizing the Delphi method and interval estimation method, the paper constructs...
A new method based on the integration of evidence theory and unascertained measure is put forward for the government investment projects evaluation. The dimensions of index system are reduced by evidence theory. Then, the data of the indexes reduced is input into unascertained measure. Empirical study has shown that the method used in the government investment projects evaluation is feasible and reliable.
A new method based on the integration of principal component analysis (PCA) and adaptive network-based fuzzy inference system ANFIS) is put forward for selecting the real estate project. Firstly, principal component analysis (PCA) is used to reduce the evaluation index dimensions. And then, adaptive network-based fuzzy inference system (ANFIS) is used to evaluate the real estate projects. In order...
A new method based on the integration of rough set theory (RS) and Back Propagation (BP) neural network is put forward for selecting the infrastructure project financing mode. Firstly, the continuous attributes in the decision system are discretized with self-organizing map (SOM) neural network. Then, the remained indicators are found by using rough set theory to reduce attributes and eliminate superfluous...
The paper presents a computer-aided decision support system for contractor selection. Based on rough set theory (RS) and principal component analysis (PCA), and, with the help of software ROSETTA and R, a computer-aid decision support system for contractor selection (CDSS-CS) is developed in this study. A case is used to demonstrate the application of this system.
Evaluation method based on the fuzzy comprehensive evaluation is brought out trying to analyze the credit of practicing qualification personnel after the index system is established. And then, a case study is executed by taking one participator of practicing qualification as an example. The research results reveal that the method can efficiently evaluate the credit of the practicing qualification...
This paper analyzes the influence of decision made by engineer about information gathering to owner's payment under the uncertainty of the fee for the unit supervising time based on the game theory. Research results indicate that there is a correlation among the owner's payment and the fee for the unit supervising time and the engineering's information. Further analytical results show that the engineer...
In group decision making (GDM) problems, fuzzy preference relations are often used by decision makers to express their opinions. This paper has proposed new two induced ordered weighted averaging (IOWA) hybrid operators improving aggregation stage developed in the resolution process of GDM problems: the dual consistency (individual consistency and collective consistency) (CIC-IOWA) operator, which...
Owing to the shortage of the city land reserve funds, loan funds generally are applied to reserve the lands besides the own funds. This paper aims at proposing city land reserve decision-making model under the condition of limited reserve funds based on market-oriented operation pattern of the city land reserve. The model can be used to confirm the reorder point in the process of land reserve, so...
The selection of engineering project manager has a decisive influence on the success of a project. Based on the analyses of the competency factors of Engineering Project Managers(EPMs), the paper constructs the framework of Engineering Project Managers' (EMPs') competencies, and, according to the framework of engineering project managers, introduces Principal Component Analysis (PCA) to select the...
