Abstract: Provided is a method of determining task scheduling probability. More specifically, the method includes establishing a set of task attributes. A database of prior task vectors in accordance with the set of task attributes then also provided, wherein each prior task vector representing a prior scheduled task. A new task is received having at least a subset of the task attributes. For this new task, a new task vector is generated based on the new task attributes. The new task vector is compared with the prior task vectors and the differences are recorded. The probability of successful scheduling is then evaluated based on the aggregate differences for each attribute. A system operable to perform the method is also provided.
