This work focuses on the development and evaluation of an economic model predictive control (EMPC) system for a non-isothermal tubular reactor where a second-order chemical reaction takes place. The tubular reactor is modeled by two nonlinear parabolic partial differential equations (PDEs). Galerkin's method is initially used to derive finite-dimensional systems that capture the dominant dynamics...
A life cycle costing (LCC) is to be performed complementary to the ongoing research on an enhanced supercapacitor pouch cell, in order to provide additional decision support on the best cell chemistry from the economic point of view. Due to the early stage of the project so far merely the production phase is considered. The detailed cost calculation method was chosen and complemented with a scale...
Simulation of the green supply chain is inundated with complexities due to reverse flows, reverse logistics, product recovery, reuse, recycling, remanufacturing, and other green initiatives. The focus of this research is to develop a conceptual framework which forms a platform for building simulation models from a discrete-event simulation perspective. First, typical green supply chain players are...
This paper presents a modeling approach based on fuzzy logic based system in order to analyze the economic sustainability of End of life vehicle (ELV) dismantlers under uncertainties. The proposed modeling approach with considering the different types of uncertainty including auto manufacturers design changes, technology market and regulations, provides a framework for auto manufacturers to evaluate...
This paper outlines the application of a special Environmental Management Information System (EMIS) that combines discrete event simulation (DES) and life cycle analysis (LCA) in addition to material flow analysis as an integrated part of the simulation software. The motivation behind the combination of these different techniques is to close the gap between identifying only parts of the life cycle,...
The environmental and economic benefits of Small and Medium Sized Enterprises (SMEs) are rarely considered during supply chain optimization. In this study, using the concept of Material Flow Cost Accounting (MFCA), an AS-IS simulation model for the supply chain comprising a Japanese gear manufacturing SME and its customer was constructed to visualize the enormous amount of waste generated by the production...
Educating engineering students on ABET-required professional and nontechnical skills is usually a challenging task. The related challenges include finding a balance between the content, the delivery format, the time of delivery, and location in the curriculum for this material. This paper presents details on a pilot project to deliver professional and academic content to engineering students via distance...
As an important element of enterprise logistics system, reverse logistics has brought significant economic benefit to an enterprise while it is also a source of costs for the enterprise. This article intends to construct a cost-benefit model of reverse logistics enabling precise computation of the total costs and ultimate benefit of reverse logistics to facilitate enterprises implementing reverse...
For many of the offshore jacket structures in Malaysia, their design lives of 25–30 years is approaching the end, signifying the urgent implementation of decommissioning efforts. While current regulatory guidelines strongly recommend complete removal of the structures, in view of sustainability issues, other options of decommissioning should not be overlooked. As a way forward, this paper suggests...
Rapid growth of construction projects have benefited mankind by providing social requirement like infrastructure, building etc as well contributing significantly in economic growth of country. At the same time is contributing significantly in generating high amount of construction waste, consuming resource excessively, and adverse impacts to environment, facing schedule delay and using excessive budget...
Community buildings are the second largest infrastructure asset owned by the governments in Australia. Mostly built in 1970s, these buildings have popularly seen significant deterioration of structure and service components, which stymied the delivery of essential services to the local communities. The sustainable management of these buildings is urgent and critical, which has to take into account...
Choosing a farmland's ecological compensation mode with low transaction cost, consideration to both fairness and efficiency and easy operation fairness, efficiency and operability, realizing the market operation of farmland ecological products, which do not only influence the effect of the ecological compensation, but also are the key to a successful implementation of ecological compensation mechanism...
The paper describes our web publication of visual teaching materials for business mathematics. The objective of the web site is to familiarize students with our visual approach for business mathematics at early stage. The significant advantage of visualization is that seeing the materials leads to better understanding of the mathematical process. Even if the students cannot understand the algebraic...
Reinforced earth retaining wall is comparatively a new construction technique. Due to its simplicity, economy and faster pace of construction, several such retaining walls have been constructed all over the world and this technique has almost replaced the conventional reinforced concrete and gravity retaining walls. To reduce the congestion on National Highway-2 at the crossing of Kalindi Kunj near...
This paper tries to conduct a comprehensive evaluation of higher education in China. Although there are many factors affecting the quality of the higher education, this paper attempts to explain the condition in a simple way. We use the students' individual abilities, students' grades, and the employment rate as the standards to judge the quality of higher education. We found out the factors that...
ICTs have a direct impact on the environment, consuming energy, materials and producing e-waste. But ICTs are the major enabling technology for mitigation of environmental impacts across all economic sectors. ICT applications and services can help limit energy use and material consumption. In other words ICTs can contribute in achieving more sustainable lifestyles, consumption and production. The...
With the development of social market economy system and the rapid development of commodity economy in our country, it is necessary to accelerate the development of sports. Researching on how to improve the economic benefit of sport investment is the core of economic activities. Both sports theory workers and leaders should pay attention to an important question of improving the economic benefit of...
This poster aims to show the importance of material availability for manufacturers, as well as provide methods to define and assess materials criticality, and tools to understand market dynamics in the short- and mid-term. These tools will help manufacturers make informed decisions about materials, and elaborate efficient strategies to mitigate the risks associated with a potential supply disruption...
Meeting present and future sustainability requirements in cathode manufacturing processes are now major issues for vacuum electron device manufacturers. Global material and energy resources, markets, and economies have direct relationships on vendor pricing, supply chains, quality and consistency of materials, and ultimately meeting customer requirements. This paper will identify and discuss historical...
Information systems development projects often involve continued commitment even in the face of negative feedback - a phenomena many describe as "escalation." Existing perspectives that explain escalation decisions implicitly make an assumption of a universal "disembedded" rationality, and characterize such commitment as a sort of paradox. In this paper, we develop an alternative,...
