Exploration of the Modeling Process of Assembly based on MBD and Pro/ENGINEER Lixin WANGa, Mingyue GUOb and Yu GUOc School of Mechanical Engineering, Zhengzhou University, Zhengzhou, 450001, P.R.China alixin.wang@zzu.edu.cn, bMingyue.Guo@hotmail.com, cguoyuzzu@gmail.com Keywords: MBD; Assembly; Pro/ENGINEER Abstract.
At last, the overall needed information (dimensions, technical requirement, BOM(Bill of Materials)) is acted upon 3D assembly model successfully through the use of functions, for example, annotation, layer and view in Pro/ENGINEER.
Thus BOM file could be derived automatically in template through menu “Info>Bill of Materials”.

The rapid development of modern technology needs the support of many new materials.
Since the third wave of science and technology swept the world, new materials, together with information energy, have been called the three-generation pillars of modern science and technology.
Material science has developed into an interdisciplinary and comprehensive discipline.
The articles collected from ICKEM 2022 introduce readers to the research results and engineering solutions in the area of materials for application in machinery, environmental engineering, biomedicine, electronics and electrical engineering.

Study on processing technique in engineering tests of Mg-7.1Gd-4.6Y-1.3Nd-0.5Zr Alloy Yongjun Lia, Kui Zhangb State Key Lab for Processes and Non-ferrous Metals, General Research Institute for Non-ferrous Metals, Beijing, China alyj@grinm.com, bzhkui@grinm.com Keywords: magnesium alloy, engineering test, homogenization treatment, plastic deformation, aging treatment Abstract.
Engineering tests using the actual production equipment and industrial production raw materials were close to the industry production.
Because the engineering test and practical engineering production was very close that the results got from engineering test could be directly applied to practical production.
So it had very important practical significance to develop engineering test that also was key step for the laboratory research results transfer to practical engineering production.
Experimental Procedure The pure metals of magnesium, yttrium, neodymium and gadolinium, and Mg-30Zr master alloys were used as rough materials.

Building Engineering Supplier Selection Based on Fuzzy Group Decision Information Aggregation CHEN Xiang1, a, ZHOU Xuefeng1, b, ZHANG Yong 2, c 1School of Civil Engineering, Xi’an Technological University, Xi’an, China 2Wuhan University of Science and Technology, Wuhan, China axichen0801@163.com, bzxf0311@126.com, cappserver@yahoo.cn Keywords: building engineering; supplier; fuzzy degree; gravity center; proximity Abstract.
Material is the precondition for the implementation of building engineering project.
Materials are a prerequisite for project implementation, materials procurement cycle and quality of materials is directly related to the progress and quality of construction projects, the successful completion of the project can effectively protect [5].
In the construction cost, total cost of construction materials accounted for about 60%-70%, so a direct materials procurement and management related to project profits.
Clearly, it is the key of supply chain management to carefully evaluate and select supplier.

The Engineering Pricing and Project Bidding Management Liping Qin1,a, Zhiqiang Zhang1 1Hubei Polytechnic University, Huangshi,Hubei, 435003 aqinlp_hbpu@163.com Key words: Engineering Pricing; Project Bidding; Management Abstract: Our current engineering pricing mode and management method still is not standard, the coexistence about all kinds of the engineering pricing method, especially the large problem of pricing method of private project.
The engineering cost accounting subject setting of Hongkong is in project start-up costs which include: insurance, temporary facilities construction costs, utilities and other eighteen kinds ; the project costs included labor costs, machinery costs, material costs, management fees, profit, engineering project risk premium and so on.
In the engineering cost accounting subjects of America ,the direct cost of project included four parts what are the labor costs, machinery costs, the cost of materials and engineering subcontracting fees; the indirect cost of project included site management fee, general management fee, the site supervision fees, management fees and temporary facilities fee, as well as the conventional site management fees of two level subjects; in the engineering of gross margin include engineering tax and net profit; in addition, there is an unpredictable fee as project risk management reserve cost.
In the engineering cost accounting subjects of Japan, the direct cost of project including subdivisional labor costs, machinery costs, material fee; Comprehensive construction fees are temporary material fees, utilities, transportation, post and Telecommunications fee; site funds include insurance, office expenses, compensation fees; integrated management fees have headquarters management fees, taxes and profits.
From these three different kinds of engineering cost, the engineering cost of national or regional structure are different and the engineering cost with our existing basic are similar, just division of project cost categories are different.

The analysis of the evolution of texts of Russian official documents related to the priority areas of science, technology and engineering, and critical technologies in 1996, 2006 and 2011 [12] that focused on the subject of “new materials”, revealed the following facts.
Unfortunately, in the next iteration that was initiated to revise the priorities of science, technology and engineering development in Russia in 2011, the official interpretation refrained from the key term “materials” and now the title of the priority we are interested in is “Industry of nanosystems”.

The production of layers and coatings with complex microstructure and application requirements (related to coated materials, the geometry of the engineered elements, economic viability) create a need for advanced technological and organizational solutions.
The development of surface engineering resulted in the emergence of many new coating materials (e.g. compound, multilayers, and gradient coatings) as well as hybrid layers produced by duplex methods.
It is these new materials that have allowed the gradual expansion of the surface engineering field in the industry, for example, in highly efficient machining or plastic forming.
Characteristics of innovative solutions in surface engineering area In the process of generating, creating, and implementation in the economy, the innovative solutions in materials and surface engineering technology must be carried out in cooperation with the industry.
The process of generating, creating, and implementing innovative solutions for the economy in materials and technology within surface engineering requires continuous, broad market analysis through cooperation with economic entities as potential recipients of emerging technical and technological solutions.
