A Systems Thinking Approach for Modelling Sustainability Impacts and Paradoxes of Product‐Service Systems

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT In recent decades, manufacturing companies have increasingly adopted product‐service systems (PSSs) business models combining products and services. PSS solutions aim for greater sustainable performance across the triple bottom line (TBL) dimensions; however, the literature emphasises the significance of accurately assessing sustainability ...

An optimizing microseismic method for rock burst early warning based on mining production process

open access: yesDeep Underground Science and Engineering, EarlyView.
A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.
