Hierarchy Process

This paper uses the Analytic Hierarchy Process to optimize the PESTEL analysis. The scenario: pre-construction and assembly factors of huge civil engineering construction projects. Several managers use too many criteria to evaluate large projects. It suggests that there may be few important criteria that summarize the manager's preference. To demonstrate the feasibility of the proposed hypothesis, the authors prepared a qualitative and exploratory study. Conclusions are based on the judgment of an expert interviewed. As expected, the hypothesis was considered plausible. Two main criteria corresponded to 71% of the expert's preference. The result resembles a Pareto distribution.

Reliable Source

As the effective and efficient means of resources utilization, biomass energy has become a very valuable and reliable source of alternative energy in China, especially for remote areas and countryside. First, in order to facilitate the development of biogas applications and promote the economic, social and ecological benefits from comprehensive utilization of biogas in rural areas in Urumqi (Capital of Xinjiang Uygur Autonomous Region, XUAR), the biogas potential was estimated, the biogas engineering construction and biogas comprehensive utilization were evaluated, and the existing problems of biogas development were analyzed, in this study. Second, countermeasures and recommendations were proposed in trying to resolved existing problems, based on international practical experience. And, according to local climatic situation and regional characteristics in Urumqi, ecological agriculture was proposed in this study as the development mode for the rural areas in Urumqi, based on the development of biogas technologies and international practical experience.

Nanotechnology can be used for design and construction processes in many areas since nanotechnology generated products have many unique characteristics. These characteristics can significantly fix current construction problems, and may change the requirement and organization of the construction process. This paper reviews the basic concept of nanotechnology, different types of nanomaterial and their manufacturing process as well as the applications of nanotechnology in different fields such as concrete, pavement engineering, construction materials. Use of nanotechnology is found to offer high performing and efficient materials. Specific application areas include water and waste water treatment, construction materials etc. The use of nanotechnology in civil engineering is still in infancy stage. The production methods, pollutions caused to human health, manufacturing difficulties, performance are the issues to be addressed in order to use the nanotechnology in civil engineering.
