“…Some indicators apply not only to one but to several groups at once. Based on the examination of the literature [18,[24][25][26][27][28][29][30][31][32][33][34][35][36], it is apparent that there are plenty of indicators with the potential to affect sustainable supply chains in construction. The identified sustainability indicators for examining the supply chains of construction companies are listed in Tables 1, 2 and 3.…”

Most of the existing supply chain management methods and systems are being transferred to construction regardless of the specifics of companies in the construction sector. Numerous complex factors such as ecological, social and economic are required for the continuous evaluation in the modern management of construction sector. The provided studies and the research to examine sustainable supply chain management in construction sector from a holistic perspective, concentrating on mostly long-term sustainable decision-making by the construction company rather than being centered only on the supply chain management for construction projects. This paper identifies a list of sustainability indicators for examining the supply chains of construction companies. Those indicators were categorized and assigned to one or a couple groups by reviewing their use in the previous literature agreeing to the reasoning to way better reflect the SSCM principle of their use in construction companies. The use of indicators can help develop strategies for the construction sector for sustainable policy makers and construction company managers.

“…Consequently, renewable energy resources employment has risen strikingly in recent years [1]. However, the reliance of these resources (e.g., wind energy and solar energy) on weather conditions and other shortcomings have put some obstacles in their improvement [2]. The stated drawbacks have made the use of an energy storage necessary.…”

Online Modeling of a Fuel Cell System for an Energy Management Strategy Design

An energy management strategy (EMS) efficiently splits the power among different sources in a hybrid fuel cell vehicle (HFCV). Most of the existing EMSs are based on static maps while a proton exchange membrane fuel cell (PEMFC) has time-varying characteristics, which can cause mismanagement in the operation of a HFCV. This paper proposes a framework for the online parameters identification of a PMEFC model while the vehicle is under operation. This identification process can be conveniently integrated into an EMS loop, regardless of the EMS type. To do so, Kalman filter (KF) is utilized to extract the parameters of a PEMFC model online. Unlike the other similar papers, special attention is given to the initialization of KF in this work. In this regard, an optimization algorithm, shuffled frog-leaping algorithm (SFLA), is employed for the initialization of the KF. The SFLA is first used offline to find the right initial values for the PEMFC model parameters using the available polarization curve. Subsequently, it tunes the covariance matrices of the KF by utilizing the initial values obtained from the first step. Finally, the tuned KF is employed online to update the parameters. The ultimate results show good accuracy and convergence improvement in the PEMFC characteristics estimation.

“…What is the difference between renewable and sustainable resources? Answers to these intriguing questions are left to the reader to be explored, but form the basis for a clear-cut understanding of sustainable development and engineering, and a safeguard against many widespread misconceptions [18].…”

With the growing consciousness of depleting material and energy resources, the concepts of renewability and sustainability are becoming increasingly important. Sustainable engineering requires improved design of products, systems, and services, targeting better environmental and social performance together with economic viability. The challenge is to reduce this powerful abstract concept into a rigorous educational framework, with clear-cut methods, tools, and metrics, so it can be integrated into engineering curricula and practiced by professionals. The United Nations defines sustainability in terms of development that meets the needs of the present without compromising the ability of future generations to meet their own needs. This requires a mutually optimal usage of natural, societal, and economic resources. Sustainability education necessitates the use of unconventional approaches as against the traditional lecture-based style. Some institutions have tried to develop a sustainability curriculum using the learning pedagogies of problem-based and project-based learning (PPBL). Using PPBL as a teaching and learning strategy facilitates cooperative learning, critical thinking, systemic reasoning, creative approach, and societal awareness, which are the core values of sustainability. However, translating this into a working curriculum is quite complex, and raises implementation issues such as physical arrangements for an active learning environment, changes in the assessment and grading system, providing both teachers and students with at least rudimentary knowledge of PPBL methods, achieving institutional support, etc. Another issue is the program-level decision of having a full dedicated course on sustainable engineering, or introducing modules on environmental engineering, green engineering, pollution prevention, waste minimization, and design for environment within a few relevant courses. The first part of this paper introduces the issues of sustainable development and sustainable engineering; the overlap of the terms sustainable, renewable, and recyclable; education for sustainable development; and pedagogy for sustainability education. The second part describes the ongoing implementation of sustainability content in the Mechanical Engineering program at our university, giving a roadmap for sustainability curriculum, and giving examples from the Product Design and the Engineering Materials courses. The last part of the paper discusses the major challenges in sustainability education, such as sustainability practice in academia, policy making issues, content overload, cultural issues, and the gray boundary between environmental protection and sustainability.
