Research on Quality Behavior Coordination of Service Manufacturing Network Node Based on AHP and Fuzzy Mathematics

Research article of American Journal of Scientific Research and Essays Research on Quality Behavior Coordination of Service Manufacturing Network Node Based on AHP and Fuzzy Mathematics (This Article has been retracted from American Journal of Scientific Research and Essays. Do not use it for any purposes) Lei ZHANG Department of Industrial Engineering, Nanchang Hangkong University, 696 Fenghe South Avenue, Nanchang, China Service-oriented manufacturing network (SMN) is a network organization model under the background of industrial integration development. Based on the quality coordination characteristics of SMN nodes, the method of hierarchical analysis and fuzzy comprehensive evaluation is introduced to study the cooperative membership of SMN nodes. This paper first constructs a three-dimensional service-oriented manufacturing network node quality behavior coordination index system including collaborative efficiency, collaborative structure and collaborative quality. Secondly, it combines analytic hierarchy process and fuzzy mathematics to determine the optimal membership degree of node indicators. Finally, it is carried out by a textile machinery enterprise. Evolutionary simulation yields the optimal membership node. Keywords: service manufacturing network; analytic hierarchy process; fuzzy evaluation ...

Concrete Strength Variations of Unwashed and Processed Coarse Aggregate Sizes

Research article of American Journal of Scientific Research and Essays Concrete Strength Variations of Unwashed and Processed Coarse Aggregate Sizes Okoro, R.I, and Ezeagu, C.A Department Of Civil Engineering Nnamdi Azikiwe University This project aims to determine the effect of different coarse aggregate sizes and type on the compressive strength of concrete. The most important property of concrete is its compressive strength. The exceeding strength of concrete is as a result of the presence of coarse aggregate. Normal concrete is being produced from different types of aggregate and size and this imparts different property to the resulting concrete. The research has established that the coarse aggregates and their sizes play critical roles in the development of adequate strength in concrete. Fine aggregate is normal sand obtained from a borrow pit. Preliminary laboratory investigation was conducted to ascertain the suitability of using the aggregates for construction work. Tests conducted include sieve analysis, bulk density, and specific gravity. From the graph of the sieve analysis for fine and coarse aggregate, the coefficient of uniformity calculated was 1.5 and 3.45 respectively. It was observed that with proper mixing, the slump test results did not witness shear or collapse type of slump rather there were true slump in all cases of the test. The result of the slump test for 12.5mm, 19.5mm, and 25mm coarse aggregate were 60, 100, and 90. The workability decreased with slight differences when the coarse aggregate size was increased. Three different sizes of coarse aggregates with 25mm maximum size for both processed (granite) and sand stone (Local stone) were employed in the investigation, namely; 12.5mm, 19.5mm and 25mm. The grading and relative densities of the aggregates were studied. The mix ratio and water / cement ratio adopted for the study was 1:2:4 and 0.5 respectively. Twelve concrete cubes (72 total) ...

Research on the application of wheel pile foundation for transmission lines

Research article of American Journal of Scientific Research and Essays Research on the application of wheel pile foundation for transmission lines Yunsheng Xu1, Sheng Wang2 and Chunyan Li1 1Department of mechanical engineering, North China Electric Power University, Baoding 071000, Hebei; 2China Electric Power Construction Hebei electric survey and Design Research Institute Co., Ltd.,ShiJiazhuang 050000,Hebei Under the action of low pressure, the wheel pile foundation bears most or even all the downward pressure. When the wheel pile foundation is subjected to uplift force, the uplift force is supported by the short pile, and the ring frame and the 4 flange mainly play the role of transfer pulling force, while the main bearing force is short and short pile. When the wheel pile foundation is subjected to horizontal forces, the horizontal force is mainly borne by the flange and the ring frame. Therefore, only downward pressure and horizontal force should be considered for the ring frame and flange, while uplift force should be considered for the design of thin and short piles. The basic design is simple and the transmission path is clear. The ring frame, flange and short pile of the wheel pile foundation are prefabricated. The foundation can take different prefabricated installation methods with the mechanized construction conditions. It can not only guarantee the quality of the concrete slab, but also speed up the construction speed of the foundation. By comparing with the economic technology of the plate foundation, it is found that under the same geological conditions, the use of wheel pile foundation can reduce the concrete earthwork and the increase of the load, the decrease of concrete is also increased, and the amount of steel is saved, and the economic benefit is remarkable. Keywords:  Transmission line; New type of wheel pile foundation; Horizontal force; Uplift force ...
