Green Smart City (GSC), is one of the new types of cities which integrates eco-concepts and information technologies. As GSC construction is a resource intensive process, it requires a large amount of knowledge, information, talent and capital. Thus, setting up an innovation ecosystem is an astute way to promote the construction of a GSC. This paper, based on the case study by the Insigma Group, tries to explore the rules of innovation ecosystem building for the construction of GSCs in China.
The paper presents a study based on the observation of public security programme situations. Nowadays, public security management is faced with challenges such as the increase in non-traditional safety threats, high occurrence probability, obvious complex chain reactions, high security demand, vulnerable bearing systems and world-wide influences. For the new adapted requirements of public security management, this paper puts forward the concept of the coordinated routine and emergency management, which combines the routine management at normal status and the emergency management at the abnormal status based on the whole process of public security management. This paper analyzes the coordinated management system and establishes the decision-making objectives, decision-making model and constraints. In addition, this paper proposes the basic strategy of achieving the coordinated management of public security.
This paper proposes a new management mode named the persistent integration and innovation management mode to satisfy the requirements by the fast development at oilfields. Taking engineering philosophy as the guidance and technical innovations in petroleum production engineering as the breaking point, the management mode combines long term production practice at oilfields with modern management methods. The management mode integrates intellectuals, techniques, capital, and information and so on to accomplish global optimization of resource configuration. Sets of new techniques, new methods, new technologies and new equipment in petroleum production engineering have been proposed under the guidance of the management mode, achieving great social and economic benefits.
Many construction projects are met with stringent timelines or the threat of exorbitant liquidated damages. In addition, construction schedulers are frequently forced to incorporate aggressive schedule compression techniques. As already discussed by previous researchers, these schedule compression techniques have direct impacts on project productivity and quality defects. Researchers have also pointed out that schedule compression will affect safety incidents such as Occupational Safety & Health Administration recordable injuries and near misses over long project durations. However, most of the existing studies treated safety as a subcategory of project productivity and project quality, and minimal research has been done to directly quantify the effect of schedule compression on safety at the project level. Therefore, in this research, we conducted a survey and statistical analysis to investigate the relationship between schedule compression and safety in construction projects. We interviewed various members of the Houston construction community from both industrial and non-industrial roles. Statistical analysis was used to identify factors that have significant impacts on the occurrence of safety incidents at an industry specific level.
Engineering project management is the whole process of project construction management activities up to the point of achieving the goals of engineering construction, which adopts the means of planning, organizing, leading, and controlling. In addition, engineering project management modes are the works of project management and the technical guarantee of project success. For the quality and efficient transformation demands of the Chinese construction industry in the process of marketization, internationalization and informatization, based on the connotation and development path of engineering project management modes, the 16 main and new kinds of project management modes both domestically and abroad are divided into trading mode, financing mode and management mode. These have led to comparative analysis and brief commentary. Finally, it will be pointed out that the engineering project management modes move throughout the whole management process, the combined model and the expansion development of financing model. This work will provide reference for project participants to choose the appropriate project management modes and better understand building company transformation.
The flue gas pollutants deep-removal technology (DRT) focusing on PM2.5 removal is the prime method of further reducing pollutants emission from coal-fired power plants. In view of the four key technological challenges in developing the DRT, studies were conducted on a series of purification technologies and the DRT was developed and successfully applied in 660 MW and 1000 MW coal-fired units. This paper analyzes the application results of the demonstration project, and proposes a roadmap for the follow-up researches and optimizations.
China’s shale gas development has had a good start. It is necessary that the developers take advantage of the opportunity to make further efforts to promote shale gas development in China, in particular by rolling out a comprehensive plan on a national level. The author makes a proposal to establish a special shale gas test area in and adjacent to the Sichuan Basin as the most important way to promote the rapid development of shale gas in China. For this purpose, the author analyzes the current situation and problems of shale gas development in China, addresses the necessity and feasibility of establishing a special test area for shale gas development, and draws up the scope of this shale gas special test area of about 450 thousand square kilometers, covering Sichuan, Chongqing, Guizhou, and part of Yunnan, Hunan, Hubei provinces, and proposes the establishment of a shale gas test area in China. This consists of an overall plan, targets, and contents in 10 aspects, along with organization and implementation modes. The shale gas exploration and development in the shale gas zones is promoted vigorously by introducing special policies and innovating exploration, development and utilization model. While at the same time, the shale gas zones of continental facies in the Ordos Basin and marine-terrigenous facies in South Hubei Basin will be established. The experiences of the reform in the shale gas zones will be the good practice for the reform of petroleum organization system.
This paper presents a new space model developed by general value engineering/value management model. The authors take the function analysis, function optimization and function realization of the development object as the basic point, to get the final optimization structure by value evaluation, so as to improve the project quality and reduce the project cost. The final case shows that the application of this model can save about 18% of the time and considerable cost of the usually planned projects under the condition of quality assurance.
