The ways and categories of integration are not single. According to different standards and angles, integration can be divided into different categories. This paper mainly classifies integration from six angles, such as range, speed, directions, levels, motivations and forms of object. Through an analysis of the categories of integration, it is helpful for us to observe, understand and study integrating...
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...
The influence of polymercaluminum ferric chloride on activated sludge system was researched by bench-scale experiment. PAFC was dropped into activated sludge system, the influence laws of dehydrogen activity (DHA), sludge volume index(SVI) and CODCr were analysed. The results show: 60mg·L-1 was optimal concentration of PAFC, DHA was increased obviously, SVI was reduced obviously, and concentration...
The killing of Microcystis aeruginosa by strong ionization discharge was studied experimentally. The relation of aeration amount, initial content of bacterium, treatment time, PH value and temperature to the killing rate of Microcystis aeruginosa was studied. The experiment has show that in a certain degree, the killing rate of Microcystis aeruginosa was raised with the increasing of aeration amount,...
The problem of the layout of NEMLCs (National Economic Mobilization Logistics Centers) is one of the most important long-term decision-making issues. The result of NEMLCs's layout directly impacts many aspects of mobilization, such as time, reliability, quality, efficiency, cost, and so on, consequently affects the effect of the mobilization. Under the restriction of mobilization time, the paper establishes...
The implementation of ERP can not only bring enterprise promotion of management, but also enhance economic benefit by a wide margin. But the success rate of enterprise put ERP into effect is low at home and abroad at present, brings enterprise much economic loss. Author found reasons of failure and successful experience from ERP cases at home and abroad, consider that series of inner and outer factor...
The supply-demand is the key research object in the market economy. Tourism cannot be realized without the supply of the tourism destination and the demand of the traveling source of tourists place. And "field" is a ubiquitous objective phenomenon that is invisible and intangible. The tourist destinations not only have the supply-demand fields but also the competition fields among destinations...
GH4169 is a difficult-to-cut nickel-based superalloy commonly used in aerospace industry. This paper presents a cutting force prediction model in the end milling of GH4169 superalloy with carbide tools by orthogonal experiment. The variance analysis is applied to check the significance of the model, accuracy of the model is verified by experiment. The effect of cutting parameters on the cutting force...
The substance of corporate social responsibility is that corporations should undertake certain social responsibilities or obligations in operation or pursuit of profit maximization. It is derived from public welfare or social responsibility undertakings, and the government generally gives preferential policies through laws and regulations as the recognition of corporations which undertake social responsibility...
With reference to Analytic Hierarchy Process, two typical types of building structures have been analyzed with the life cycle assessment technology. Through comparison, differences in environmental impact during the life cycle and the relationship between the environmental impact and the direct economic have been found. The results showed that the steel structure has a greater impact than the reinforced...
Human-based Management is an inevitable development trend in modern enterprises management; it is the requirement of complete human-being development on enterprise management. Human-based management, i.e. the commonly called "human oriented", means regarding human being as the core of management activities, highlighting the management thought of promoting the completion of organization goals...
The volatile oils were extracted from Typha latifolia by Water-steam distillation. Components of the volatile oils were analyzed and identified by gas chromatograph-mass spectrometry (GC-MS), and the allelopathic effect of the volatile oils were also explored by bioassay of Microcystin aeruginosa. The results showed that the volatile oils had activity to inhibit the growth of M. aeruginosa. This study...
Accident is originated by hidden danger. Discovering and removing hidden dangers is one main approach to prevent and control accidents. This paper collected and analyzed the information of hidden dangers from multiple coal mines. On that basis, we put forward concepts of hidden danger information and standard database of hidden danger information, introduced the structure and build flow chart of standard...
In China, power supply company has solved a lot of problems of rural power management by computer. Because informatization is not enough, grassroots power supply companies have different situations and some promoting softwares could not satisfy grassroots units' individual needs. At present, there are still some problems of rural power management in city county-level power supply company, such as...
In the design of disastrous memorial building, obtaining theme is the soul of creation, which can record disaster (or calamity) culture. By comprehensively using expression techniques of "straight", "symbolization" and "metaphor", three creation thinking of "Cheng (Presenting)", "Zhuan (Changing)" and "Qi (enlightening)" can earn the emotional...
GMZ bentonite is chosen as the main buffer material to be mixed with quartz sand in different sand addition of 0, 10, 20, 30, 40 and 50%. Laboratory tests were conducted on the compacted bentonite-sand mixture for swelling strain. Test results show that quartz sand can restrain the swelling deformation property of bentonite-sand mixture, and the maximum swelling strain decrease with sand addition...
Sustainable construction is to maximize the efficient use of our building, to minimize and eventually eliminate the building on human health and the negative impact of the environment. This passage describes the development present situation of the sustainable architecture design projects at domestic and abroad, introduce several typical projects. We propose strategy for sustainable building design,...
In order to adapt to the new situation of the construction market, and consider to serve the construction market and the project cost management, the establishment of the Web-based Construction Cost Management Information System is of great practical significance. Through the establishment of a complete and systemic construction project cost information database, and the process for all kinds of cost...
With deepply research thunderbolt's critical materials safeguard working rule, the paper has analyzed our country critical materials reserve present situation, proposed based on the AHP critical materials taxonomic approach. In view of the critical materials safeguard's characteristic, has constructed the cross time critical materials inventory control model and the critical materials information...
Against the issue about revenue maximization of cycle project product, apply ideas of game balance, base on a single product manufacturers and retailers in closed-loop system, study when recycling waste products, decentralized decision-making model and a joint pricing strategies of enterprises; In considering the environmental costs of products, proposed differential pricing policy model in product...
