A hierarchical consistency problem for the hierarchical supervisory control of discrete event systems under partial observation is considered, since observability is a practical and general property in real systems. The notion of H-observability is introduced to ensure hierarchical consistency between lowand high-level systems, and an analytical framework for the hierarchical supervisory contro...

Head of Department, also known as a nurse manager, has the responsibility monitoring quality care, addressing workforce issues, and ensuring effective performance. One roles Department is to act leader in department, controlling evaluating implementation predetermined nursing well organizing coordinating all activities ward through collaboration with other staff members. This study aims determi...

Coalgebraic techniques are applied to the supervisory control of discrete-event systems with partial observations. Classical notions from concurrency theory are specialized to control theory. The concept of weak transitions enables the relational characterization of observability and gives rise to a coalgebraic formulation of the necessary and sufficient conditions for the existence of a superv...

Adaptive Controllers are susceptible to many commonly occurring implementation problems, and require some form of supervision to maintain good performance. In this thesis a two level adaptive control strategy is presented that uses an expert system to diagnose and correct problems with an adaptive controller. In contrast with other expert supervised adaptive control schemes, where problem treat...

In today’s competitive world, manufacturers have realized that they need to embrace automation as their mantra to success. However, the impact of automation primarily concerns with the effectiveness of process monitoring and control systems. There is a need for a closed loop supervisory system, which integrates and coordinates individual process modules for real-time adjustment, conflict resolu...

As a historical era, postmodernism signifies transition from inflexible and logical positivism and entry into a new view to science. Postmodernism offers a number of nursing practice revise that including humanism, conditions, and borderless, multi-voice, view, and multicultural world, changes in meaning of knowledge, and life-long learning. Demographic changes, technological advances, ethnic a...

This paper focuses on issues related to implementing timed discrete-event systems (TDES) supervisors, and the concurrency and timing delay issues involved. In particular, we examine issues related to implementing TDES as sampled-data (SD) controllers. An SD controller is driven by a periodic clock and sees the system as a series of inputs and outputs. On each clock edge (tick event), it samples...
