At present NMS supports a configurable option for how many hours the user wishes to run a detailed forecast for, and to specify the length of the forecast window ie 7 days, with a Daily Worst case analysis provided for those days beyond the detailed forecast window. Extending the detailed forecast window has a significant performance impact. Our preference would be to have a configurable option that allows for a detailed forecast for a nominated future day, miniminsing the performance impact of those days days where the analysis is not required.
