A decision problem that is ongoing, so its data values are frequently changing with uncertainty. Here are some examples:

  1. Allocation of bandwidth during video conferencing on a telecommunications network;
  2. Investment decisions in a portfolio, selling and buying as the market changes;
  3. Scheduling jobs as they arrive;
  4. Load forecasting and dispatching for electric power.

In general, an online decision problem could be the allocation of resources that is done in real time with changes in the amount of resources, their costs and the demands for what they produce. A problem that is not online is sometimes called an offline problem.
