This paper summarizes a mathematical model for the industrial heating and cooling processes of steel workpiece corresponding to steering rack an automobile. The general purpose heat treatment process is create necessary hardness on critical parts workpiece. Hardening consists up threshold temperature followed by rapid such as aquaquenching. high due phase transformation accompanying resulting i...

Still not long ago operators were struggling with middlebox deployment and traffic management across them. The service chaining problem was a well studied subject which had to deal with the limitations of middleboxes and offer various techniques to overcome them to achieve the desired traffic steering [6, 7]. Only two years have passed its official launch by ETSI [1], but network function virtu...

At present, the country's coal industry pays special attention to open-pit mining, because of its higher efficiency and profitability. According various surveys, currently share mining is 50 - 65%, it will increase 80 85% in future. The development an accompanied by production scale increase, open pits depth increases complexity conditions main technological equipment operation increases. With ...

Inexpensive analog phase array antennas are on the verge of becoming widely available. These versatile antennas are capable of very rapidly altering their gain pattern to form complex patterns. However, previous research has shown that problems arise when using the stock 802.11 MAC protocol with directional antennas, and new MAC protocols have been designed to address these issues as well as ex...

The determination of the optimal carrying capacity procurement of rail and shipping services in the automobile intermodal network with unique characteristics is essential to save automobile delivery cost. In this research we develop a two-stage stochastic programming model for the tactical-level decision problem arising in the special automobile intermodal network. Furthermore, we improve the s...

With the Covid 19 pandemic, many sectors on a global scale have been affected by this situation. In Turkey, automobile industry faced with high price volatilities and used car prices increased drastically, indeed, they surged brand new ones. Thus, purpose of study is examining two different time May 2020 Mar 2021 Hedonic Price Model (HPM). For purpose, cross-sectional linear regression method a...

Today, planning and control of logistic processes on automobile terminals are generally executed by centralised logistics systems, which in many cases cannot cope with the high requirements for flexible order processing due to increasing dynamics and complexity. The main business processes on automobile terminals – notification of vehicles by automobile manufacturer, transport to automobile ter...

China’s automobile industry has made great progress and contributed a lot to national economic development, but the problems such as dispersion, small, disorderly, worse" in the industry is still very serious. Starting from the SCP paradigm theory in China’s automobile industry, the article analyses the problems including the market structure, market conduct and market performance in China’s au...
