Together, these two factors guarantee that the process of constructing an optimal schedule will be costly and the chances of executing that schedule will be slight. Temporal uncertainty in the task execution time can be offset by several methods: eliminate uncertainty by careful engineering, restore certainty whenever it is lost, reduce the uncertainty by using more accurate sensors, and quantify and circumscribe the remaining uncertainty. Unfortunately, these methods focus exclusively on the ","authors_text":"B. R. Fox, Karl G.
