Ecologically Inspired Water Network Optimization of Steel Manufacture Using Constructed Wetlands as a Article

Kaili Zhang,Stephen M. Malone,Bert Bras,Marc Weissburg,Yuehong Zhao,Hongbin Cao

Engineering 2018, Volume 4, Issue 4,   Pages 567-573 doi: 10.1016/j.eng.2018.07.007

Abstract:

Traditional optimization models often lack a systems-level perspective at conception, which limits their effectiveness. Expanding system boundaries allow scientists and engineers to model complex interactions more accurately, leading to higher efficiency and profitability in industrial systems. Ecological systems have evolved for billions of years under conditions of material and energy shortage, and ecologists have defined analysis tools and metrics for identifying important principles. These principles may provide the framework to circumvent the limitations of traditional optimization techniques. More specifically, by recruiting functional roles that are often found in ecological systems, but are absent in industrial systems, industries can better mimic how natural systems organize themselves. The objective of this analysis is to traditionally optimize a manufacturing process by comparing the model with ecological and resource-based performance metrics in order to redesign the model with the addition of important functional roles that are found throughout nature. Industry partners provided data for this analysis, which involved building a water network for an existing steel manufacturing facility in China. The results of the traditional optimization model indicate a 23%, 29%, and 20% decline in freshwater consumption, wastewater discharge, and total annual cost, respectively. However, our ecologically inspired optimization model provides an additional 21% and 25% decline in freshwater consumption and total annual cost, respectively. Furthermore, no water is discharged. These results suggest that this unconventional approach to optimization could provide an effective technique not used by existing algorithms to solve the challenging problem of pursuing more sustainable industrial systems.

Mathematical model and manufacture programming of loxodromic-type normal circular-arc spiral bevel gear

Zhenyun DUAN, Houjun CHEN, Zhilan JU, Jian LIU

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 3,   Pages 312-321 doi: 10.1007/s11465-012-0308-5

Abstract:

In this paper, loxodromic-type normal circular-arc spiral bevel gear is proposed as a novel application of the circular-arc tooth profile at the gear transmission with intersecting axes. Based on the principle of molding-surface conjugation, the study develops a mathematical model for the tooth alignment curve and the computational flow at the design stage to enable the generation of the tooth surface. Machining of the tooth surface is then carried out to determine the interference-free tool path of the numerical control (NC). Moreover, a pair of loxodromic-type normal circular-arc spiral bevel gears is manufactured on computer numerical control (CNC) machine tools. The proposed theory and method are experimentally investigated, and the obtained results primarily reflect the superior performance of the proposed novel gear.

Technological and Economical Logic for Intelligent Manufacturing

Guo Zhaohui

Strategic Study of CAE 2018, Volume 20, Issue 4,   Pages 97-100 doi: 10.15302/J-SSCAE-2018.04.016

Abstract:

Focusing on the difficulties domestic industrial enterprises are facing while promoting intelligent manufacturing, this article introduces the methods for facilitating in-depth application of related technologies. It is shown through research and comparison, that the fundamental cause of these difficulties is the poor economic efficiency of technology. Therefore, the key to promote the application of certain technology is to improve the economic efficiency of technology. Besides, problems such as out-dated management levels and low requirements for quality are the general causes restraining the economic efficiency of technology. To promote the economic efficiency of technology, strategic goals have to be set for technological transformation and upgrading on a business level, and a higher quality standard should also be set. Meanwhile, intelligent manufacturing related technologies can be used to promote the management level and to address the weaknesses of the enterprises, thus to improve the economic efficiency of technology.
