Outline of Final Research Achievements |
We have focused on event driven discrete event systems in which the duration times of processes are adjustable or vary stochastically. The behavior of target systems was represented using max-plus algebra, and scheduling methods with lightweight computation load were developed. For systems in which both the control inputs and system parameters are adjustable, we applied the concept of model predictive control, and designed a controller for hybrid systems in which there are both continuous and discrete variables. On the other hand, we applied the concept of the Critical Chain Project Management (CCPM) method to systems with highly uncertain processing times. In constructing the framework for calculating a desirable schedule, max-plus algebra was used to avoid multiple integration.
