Construction enterprises are faced with major changes of the construction industry and market, and innovation has become an important development measure for the construction enterprises to cope with the market crisis, expand the living space, and create a new profit point. This paper analyzes the necessity of innovation-driven development of construction enterprises, and puts forward the general...
The success or failure of a construction project depends largely on the contractor's performance since they are responsible for important activities in the building process. In this way, it is necessary to monitor the performance of the contractors who already working with the organization to control failures during the development of work. Due the complexity and necessity of considering various criteria...
Since the separation of ownership and management in companies, senior managers as the company's core decision-making, their pay is directly linked to company performance. In this paper takes the construction industry as its object of study, selecting total assets net profit margin, return on equity, earnings per share, total assets, asset-liability ratio indicators which can measure the company performance...
the use of Earned Value Management (EVM) is of paramount importance for the successful delivery of construction projects. This paper evaluates the use of EVM in the United Arab Emirates (UAE) construction industry and identifies the key factors for its successful implementation. The success factors are identified through literature review. The paper is based on the assessment of survey responses from...
The main aim of this paper is to identify the main causes for the delays in the Portuguese construction industry and its impact, with the purpose of increasing knowledge on the causes and impacts of delays in construction projects. The Relative Importance Index was adopted to classify the importance of the 47 causes and six impacts identified causes of delays. Results show the main causes of delay...
Both China and Japan have great influence on the Asia-Pacific and even the world economy. China's development is obvious to all. Chinese construction industry has made significant achievements in recent years. As one of the developed countries, Japan has been stagnating for several years. After decade years of decline, the Japanese construction industry recovered in 2008 and accelerated slightly from...
Combining with the characteristics of the construction enterprise, this paper establishes the construction enterprise competitiveness evaluation index system on the basis of the analysis of the current situation of evaluation methods. The rough set is utilized to make reduction of evaluation index and calculate the reduced index weight by through AHP. Then the fuzzy comprehensive evaluation is applied...
Based on Fisher's Linear Discriminant Analysis, the paper proposed an early warning model to predict the bankruptcy possibility for construction companies in China. Sample and variable set of the study came from 56 privately owned Chinese construction companies and their financial ratios, and 27 companies' crisis occurred during the period 2008–2009. Kolmogorov-Smirnov test was used to examine the...
This paper firstly gives a construction safety evaluation system based on previously researches. Secondly, it gives the concept of intuitionistic fuzzy sets concisely. Then, intuitionistic fuzzy TOPSIS method is introduced. Finally, a numerical example for safety evaluation is given to illustrate application of the method.
With increasing of building energy consumption in China, the role of green architecture in the sustainable development of construction industry is more and more important. As the living standard of people improved, together with high-demand of comfort level, the energy consumption of resident buildings which are so closely related to our lives tends to increase rapidly. In this situation, we should...
As the energy supply lack and climate deterioration, carbon emissions problem is more and more concerned by the world. For construction industry, its related products consume large amount of energy and lead to heavy carbon emissions. In order to provide a rule in evaluating low-carbon performance of buildings, an evaluation frame is given from both life-cycle and low carbon of buildings, and detailed...
The comprehensive index system for expressway project was set up in order to study the investment expense of expressway project under the influence of multi-factors from economic, technical and policy aspects. Grey relational analysis method was utilized to quantitatively analyze the factors that affect highway construction expense, which could determine the key factors of controlling different terrain...
This paper proposes the approach of analyzing risk of deep excavation engineering based on fuzzy theory. By using fuzzy mathematical method, the risk assessment model is established, and a practical method on fuzzy comprehensive assessment on risk of deep excavation engineering is proposed, and the practicability of this method is verified in a real engineering projects.
According to the principle of multi-target extension, matter-element analysis constructed a new evaluation method of sustainable housing projects, which was based on element model, extension theory of mathematical methods and correlation functions. At the same time, the example showed that the entropy theory utilized to calculate the correlation index weights in this new method could also avoid subjective...
Green construction assessment based on project attributes is introduced in this paper. This assessment method is achieved by the considering of weight coefficients of every construction stage in a project and evaluative aspects via AHP. And the integrated weight coefficients worked out of a group of experts as well as software Visual FoxPro.
This thesis puts forward 11 main influence factors which may have impact on the informatization construction by identifying the internal and external influence factors. And this paper processes the surveyed data of 12 enterprises in northeast area based on grey relational analysis according to the gray character of Enterprise's cognitive to some of the influence factors, and it calculates the correlation...
The large-scale construction enterprise project portfolio management is a effective integration bridge of strategic goal and project management, under the guidance of the corporate strategy, project selection is a key scientific factor. In this paper, Vague sets' TOPSIS algorithm, Comparison the distance between the project set A of the project solution and Vague positive-ideal solution (VPIS) and...
This paper establishes a post-evaluation index system which can be used to economic benefits post-evaluation on the grid construction projects. According to the features of this project evaluation, the membership functions using to evaluate indexes is formed and the value weight is determined by fuzzy AHP .Then, this method is applied to one project with economic effects evaluation. This method can...
Material procurement is the very first link in the course of construction project, which relates to project cost, quality, and time limit and so on. Therefore, the selection of supplier is particularly important. In this paper, a two-stage model of supplier selection in project has been constructed by rough set and multi-objective liner programming based approach. The application of rough set based...
Combined with the actual situation of China's construction enterprises, based on the growth-medium-sized enterprises evaluation method published by “Research for Small Medium-sized Enterprises Development” joint research projects group, and by using fuzzy clustering analysis to analyze the eight evaluation index systematically which determine the enterprises growth, the sorting of evaluation index...
