A Method for Assessing the Risks to Sustainability Posed by Process Operations
Sustainable Development, EarlyView.ABSTRACT We present a framework for assessing the risks to sustainability posed by any given set of processes. The objective is to improve sustainability by enabling better decision‐making in policy and business contexts. The framework can be applied to any system of processes where available information supports discovery and quantification of ...

Modelling single line train operations [PDF]
, 1995 Scheduling of trains on a single line involves using train priorities for the resolution of conflicts. The mathematical programming model described in the first part of this paper schedules trains over a single line track when the priority of each train ...

Sustainable Development, EarlyView.ABSTRACT Displacing people to make way for development projects is contentious. Empirical research demonstrates that neither human rights guidelines nor multilateral lenders' standards guarantee positive, sustainable outcomes for displaced people. With multiple new displacing projects proposed globally, including for renewable energy, we propose a new ...

When should firms watch for cross‐industry competition? A demand‐side perspective
Strategic Management Journal, EarlyView.Abstract Research Summary Research on competitor identification has primarily focused on intra‐industry competition. However, cross‐industry competitive threats are prevalent and consequential. We adopt a consumer‐oriented perspective to examine how consumer perceptions shape de facto competition across industry boundaries.
