Action-Based Union of the Temporal Opposites in Scheduling: Non-Deterministic Approach

Junichi Yagi, Eiji Arai, Shinji Matsumoto

It is the time resource that one deals with in scheduling. The task is how one can achieve the optimal allocation of a given time resource over a set of assigned activities. Most of the existing scheduling methods use a parametric time by which the activities are orderly allocated in accordance with the order of events. The parametric methods however fail in incorporating a dynamic aspect of scheduling that unfolds itself as the project proceeds, and also uncertainty that the starting and ending nodes of an activity fluctuate. This paper reformulates the concept of time to match to a dynamic scheduling through a non-deterministic approach. In particular, time can be regarded as an object in the holographic space, which models the dynamic aspects of time as a “mapped/ represented” and “transformed/ processed” temporal movement.
