Precision farming, precision agriculture or site-specific management (SSM) is a management system where crop production practices and inputs such as seed, fertilizers and pesticides are variably applied within a field. Input rates are based on the needs for optimum production at each within-field location. Since over-application and under-application of agrochemicals are both minimized, this st...

This paper develops economic production quantity (EPQ)-based models with planned backorders to evaluate the impact of the postponement strategy on a manufacturer in a supply chain. We derive the optimal total average costs per unit time for producing and keeping n end-products in a postponement system and a nonpostponement system, respectively. By comparing the optimal total average costs of th...

Clinical trials pose increasing challenges to sponsors and regulators in terms of execution complexity, timing constraints, risk management, and quality of scientific output. We show how the systematic use of clinical trial data standards, combined with the application of model driven semantic technology within the context of a metadata registry can provide a radical but more effective way to s...
