Parallel Algorithms for Fuzzy Data Processing

Jo Hartley

The research involves the development of parallel algorithms, for the processing of fuzzy data and quantification of the confidence limits of the results, and the development of a parallel programming metalanguage for the efficient implementation of such algorithms. The parallel structure of these algorithms will enable modular augmentation of the processing hardware (transputer network) in line with the increase of the size of the simulated systems. The algorithms are tested in the context of operational decision support of a water distribution system.

The individual developments include:

• An Appropriate State Estimator
• Parallel State Estimation
• Confidence Limit Analysis of the State Estimate
• A Parallel Metalanguage

• An Operational Decision Support of Water Distribution Systems.
