Ambulance service operational improvement

Ambulance Service Planning Simulation and Data Visualization

The ambulance-planning problem includes operational decisions such as choice of dispatching policy, strategic decisions such as where ambulances should be stationed and at what times they should operate, and tactical decisions such as station location selection. Any solution to this problem requires careful balancing of political, economic and medical objectives. Quantitative decision processes...

Analysis of 1000 consecutive patients brought to the accident and emergency department of a busy district general hospital by ambulance after emergency "999" telephone calls showed that 51.7% of these journeys were unnecessary. Medical cases accounted for a greater percentage of necessary calls than did trauma and surgical cases. Medical education of the public is essential if the number of the...

Parametric Polymorphism and Operational Improvement

Parametricity, in both operational and denotational forms, has long been a useful tool for reasoning about program correctness. However, there is as yet no comparable technique for reasoning about program improvement, that is, when one program uses fewer resources than another. Existing theories of parametricity cannot be used to address this problem as they are agnostic with regard to resource...
