Dead-Zone (DZ) Logic for Self-stability

Speaker: Dr Thaddeus Eze, Senior Lecturer, CSEEE Department, University of Chester

This presentation will discuss Dead-Zone (DZ) Logic as a shareable technique that could be used in many fields.

Dead-Zone (DZ) logic is a simple mechanism to prevent unnecessary, inefficient and ineffective control brevity when, for example, a self-adapting system is sufficiently close to its target state. It is implemented using a Tolerance-Range-Check (TRC) object. The TRC object encapsulates DZ logic and a three-way decision fork that flags which action amongst three options (e.g., increase value, decrease value or don’t change value) to take depending on the rules specified. It provides a natural and powerful framework for achieving dependable self-management in autonomic systems by enabling autonomic managers to smartly carry out a change (or adapt) only when it is safe and efficient to do so -within a particular (defined) safety margin.

This presentation will demonstrate a performance impact of dead-zone logic in a self-adapting datacentre resource request and allocation management case study.


This seminar is to discuss Shareable Techniques that other researchers might find interesting and useful for their own research.
