Social network analysis reveals that communication gaps may prevent effective water management in the mining sector
تجزیه و تحلیل شبکه های اجتماعی نشان می دهد که شکاف های ارتباطی ممکن است از مدیریت موثر آب در بخش معدن جلوگیری کند-2017 Sustainability issues are often difficult for companies to manage because they require communication
across organisational departments and divisions. This paper provides some of the first empirical evi
dence that communication “silos” exist within the mining sector, and that they may be impeding
effective water management. Results of a social network analysis at a mining company revealed gaps in
direct communication about water-related issues between the two largest production departments. This
gap was particularly surprising because the departments were connected in the other communication
networks studied, namely: information, ideas, problem-solving and friendship. The Health, Safety and
Environment department played a crucial brokerage role within the water network, suggesting that
water is primarily perceived as an environmental issue. A lack of direct communication between the
major production departments could pose a barrier for recognising and responding to production-critical
water risks. The work also found that the water network was characteristic of a core-periphery structure,
such that communication was vulnerable to the removal of central “hubs”. These hubs were dominated
by senior management, which may present a risk for responding promptly to water-related crises.
Further research is needed to investigate the impacts of a siloed communication structure for managing
other sustainability issues including energy and community development.

Sustainable supply chain management and the transition towards a circular economy: Evidence and some applications
مدیریت زنجیره تامین پایدار و انتقال به سوی یک اقتصاد دایره ای: شواهد و برخی از برنامه های کاربردی-2017 In the last decades, green and sustainable supply chain management practices have been developed,
trying to integrate environmental concerns into organisations by reducing unintended negative
consequences on the environment of production and consumption processes. In parallel to this, the
circular economy discourse has been propagated in the industrial ecology literature and practice.
Circular economy pushes the frontiers of environmental sustainability by emphasising the idea of
transforming products in such a way that there are workable relationships between ecological systems
and economic growth. Therefore, circular economy is not just concerned with the reduction of the use of
the environment as a sink for residuals but rather with the creation of self-sustaining production
systems in which materials are used over and over again.
Through two case studies from different process industries (chemical and food), this paper compares
the performances of traditional and circular production systems across a range of indicators. Direct,
indirect and total lifecycle emissions, waste recovered, virgin resources use, as well as carbon maps
(which provide a holistic visibility of the entire supply chain) are presented. The paper asserts that an
integration of circular economy principles within sustainable supply chain management can provide
clear advantages from an environmental point view. Emerging supply chain management challenges and
market dynamics are also highlighted and discussed.

شبیهسازی انرژی در سیستمهای تولید انعطافپذیر بر اساس شبکه زمانی رنگی پتری
سال انتشار: 2014 - تعداد صفحات فایل pdf انگلیسی: 9 - تعداد صفحات فایل doc فارسی: 20 فشارهای اعمالی از طرف دستورالعملها و استانداردها باعث شده تا کارخانههای تولیدی به ارزیابی وضعیت انرژی خود بپردازند تا عملکرد اقتصادی و محیطزیستی خود را بهبود بخشند . سیستمهای تولید انعطافپذیر (FMS) به دلیل دشواری و پیچیدگی جمعآوری داده از آنها به چالشی در مدیریت انرژی تبدیل شدهاند . FMS به تولیدکننده اجازه میدهد تا خود را با نیاز مشتری تطبیق دهد و خواستههای متفاوت را برآورده کند و با سرعت به نیاز بازار پاسخ دهد . برای حل این چالش ، یک مدل کاربردی انرژی برای سیستمهای ماشینکاری بر اساس شبکه زمانی رنگی پتری (CTPN) ارائه شده است . در این مقاله ، ابتدا مصرف انرژی FMS ها تحلیل میشود . سپس یک مدل انرژی برای FMS بر اساس CTPN ارائه میشود که در آن عدم قطعیت واگذاری وظیفه و تغییرات ناگهانی زمان عملیاتها توسط توابع شبکه پتری (PN) بحث میشود به نحوی که اطلاعات مصرف انرژی به طور خودکار جمعآوری شوند . در آخر ، از طریق مطالعه و بررسی یک FMS با دو وظیفه ، مدل انرژی ارائه شده شبیهسازی میشود و نتایج شبیهسازی از طریق ابزارهای رنگی PN نمایش داده میشوند .
