Fuzzy Based Design for Third-Party Pipeline Failures in the Niger Delta Region of Nigeria|
ARIAVIE, G.O.; EMETITIRI, R.E.; ONONEME, O.E. & OLOWU, I.D.
A Fuzzy based design for assessing failures of pipelines occasioned by third
party in the Niger Delta Region of Nigeria has been proposed in this study. Twelve factors
earlier identified by Ariavie et al (2010), were further grouped into four, viz : violence,
desperation, misconduct and agricultural categories to allow for a less tedious rule base
development. Each category has inputs (base inputs) plugged into it which is in turn plugged
into another system (main engine). Based on this, the fuzzy model was designed, using
MATLAB fuzzy toolbox to develop a hypothetical simulation which simply involves the
feeding of randomly generated values between 0 and 1 to the controllers. The evaluation
process of the first expert is presented and obtained for the four categories Risk values as
0.533, 0.509, 0.442 and 0.552 for violence, desperation, misconduct and agricultural
respectively, with total risk value being 0.063.
