Abstract:The importance of timely detection, classification and response to anomalies on petroleum products pipeline (PPP) have attracted pragmatic researches in recent times. There is need for efficient monitoring and detection of activities on PPP to guide leak detections and remedy decisions. This paper develops an intelligent hybrid system, driven by discrete event system specification (DEVS) and adaptive neuro-fuzzy inference system (ANFIS) for detection and classification of activities on PPP.

“…The modifications were done in backward direction from the output layer through each hidden layer down to the first hidden layer and the process was repeated until an acceptable low error is attained. In this case, the network is able to learn the data patterns (Udoh, 2016).…”

“…These modifications are done in backward direction from the output layer through each hidden layer down to the first hidden layer. The back-propagation algorithm is discussed in (Acharya et al, 2003;Han et al, 2012;Obot, 2007;Udoh, 2016;George, 2019).…”
Having a mixture of similar items that needs to be separated for processing or for storage is a common challenge. Dalium guineense (DG) is a wild fruit with epicarp that could be broken accidentally or intentionally during harvest or in the course of processing. This research attempts to develop a model for classification of DG fruits into whole fruits and deshelled fruits each with fifteen physical characteristics (Length (l), width (w), thickness (t), geometric mean diameter, arithmetic mean diameter, specific mean diameter, equivalent mean diameter, surface area, aspect ratio, surface area, sphericity, unit mass, lw (product of length and width), lt (product of length and thickness) and wt (product of width and thickness)) using a machine learning approach. A 15-3-2 Neural Network (NN) architecture was used to develop the classification model. The deshelled fruits were all correctly classified while 95 of the whole fruits were correctly classified with 5 of the fruits misclassified. The result shows that the classification model was able to achieve an accuracy of 97.5%, sensitivity of 100%, and precision of 95.2%. Increasing the number of processing elements in the hidden processing layer of the NN contributed no positive effect on the performance of the model. This model is therefore suitable for classification purpose, leading to appropriate processing and handling of DG with high accuracy.
