A Network-Based Method for the EMU Train High-Level Maintenance Planning Problem

Electric Multiple Unit (EMU) high-level maintenance planning is a typical discrete system. EMU high-level maintenance (HM) planning determines when to undergo HM or execute transportation task for train-sets, based on practical requirements such as passenger transport demand, workshop maintenance capacity, and maintenance regulations. This research constructs a time-state network that can displ...

An Outline of the Process of Economic Change

UNDERSTANDING economic change including everything from the rise of the Western world to the demise of the Soviet Union requires that we cast a net much broader than purely economic change because it is a result of changes (1) in the quantity and quality of human beings; (2) in the stock of human knowledge particularly as applied to the human command over nature; and (3) in the institutional fr...

QUANTALE-VALUED GAUGE SPACES

We introduce a quantale-valued generalization of approach spaces in terms of quantale-valued gauges. The resulting category is shown to be topological and to possess an initially dense object. Moreover we show that the category of quantale-valued approach spaces defined recently in terms of quantale-valued closures is a coreflective subcategory of our category and, for certain choices of the qu...

Technical Efficiency versus Technical Change – the British Passenger Train Operators

This paper considers the technical efficiency gains that have been achieved since privatisation of the British passenger railway. This is done through estimation of a stochastic efficiency frontier, with efficiency gains split between those arising through technical change and those arising out of management technical performance i.e. total factor productivity. The results suggest that most of ...
