Abstract

ABSTRACTExisting energy-monitoring tools do not offer to monitor the basic 3 C’s of energy, that is, cost, carbon emission and more importantly direct energy consumption with its associated value-added and auxiliary components in a single envelope during the entire hierarchy of a manufacturing process. The visualisation of these hierarchical Key process indicators (KPIs), however, poses a multi-dimensional and hierarchal data visualisation problem. We in this paper introduce through Focus-plus-Context and treemap visualisation techniques, a platform-independent pervasive software solution, providing task-based contextual visualisation of hierarchical, multi-dimensional and relevant energy KPIs such as Total Production Units with total production energy consumed, Energy Intensity, Energy cost per production unit and Carbon emission through the entire manufacturing hierarchy of a product drilling down from the factory level to specific production lines, machines or processes. A comparison of existing energy management software along with multi-dimensional visualisation techniques is also presented in this paper.
