A process model is used to study energy use and conservation in the steel industry in India. Production is modelled by a set of inter-connected process activities, each of which defines unique relationships between process output and a number of inputs. Contrary to that in process models for the...

We present a goal programming (GP) model designed to capture multiple objectives involved in sustainable energy-environment management in an urban area. The basic structure in the GP model is a Reference Energy System (RES) that maps the optimal flow of intermediate forms of energy from supply...
