WORK PACKAGE 4
The following activities were carried out as part of Work Package 4:
- Study of typical water distribution network topologies, based on both the literature and real data from actual networks in Greece.
- Identification of network devices and functional units
- Modeling water distribution networks as discrete event systems
- Identification of desired operational characteristics for the hydraulic behavior and functionality of the devices.
- Formulation of operating rules aimed at ensuring proper hydraulic operation.
- Defining rules that describe the normal operation of devices in the absence of faults
- Defining the desired characteristics of quality variables, in accordance with international, European, and national guidelines
- Formulating rules for compliance with quality criteria
- Formulation of rules for safe observer switching
- Formulation of formal languages describing the rules for safe observer switching
- Design and development of monitors that enforce the rules for safe observer switching
- Defining the controlled system as a controlled automaton and performing a systematic analysis of the properties of the physical realizability of supervisors and the deadlock avoidance
- Adaptation of the design of the supervisory control system for the case of unobservable events – design of diagnosis and observer systems for discrete event models of water distribution networks with unobservable events
- Design of a hybrid system that combines continuous and discrete event system monitoring
The open-source codes developed for WP4 are available here.
