The roof maintenance problem — a fuzzy expert system

Abstract

Roof maintenance is an issue that has ongoing ramifications for property owners, all over the world. Determining accurately what maintenance should be taken is difficult, with often-conflicting evidence further complicating the task.

A system has been developed for use by Roof Maintenance Experts. The expert can input information about the condition of the roof then a Fuzzy Neural Network makes an assessment, returning probable roof maintenance options.

This is a non-trivial problem from the realworld domain. Often, many combinations of possible maintenance can occur and, as individual parameters change, so does the prime (or most important) option.

A fuzzy neural network system was developed for assessment, running on a handheld device that could be taken into the field by a roof maintenance expert.
