    Fuzzy Logic Based Motor Speed Controlling System for Automobile Industry
    (Uva Wellassa University of Sri Lanka, 2020) Hemakeerthi, D.A.B.; Wijesinghe, W.A.S.
    Road safety is becoming an important case in all over the world today. The number of deaths is increasing day by day inroads, due to the uncontrollable speed of drivers and accidental sleepiness while driving. The objective of this project is to develop a system to protect both vehicles and passengers on the road. The main aim of this project is to control the speed of a vehicle automatically by controlling the speed of the motor using fuzzy logic. Which reduces the driver’s task for adjusting the gas pedal and checking the speedometer frequently. The research introduced the Fuzzy Logic for speed controlling instead of the commonly used methods such as RF signal controlling method; because Fuzzy logic controllers (FLC) can be used to utilize the human expertise and experience for design controllers. The purpose of using a fuzzy logic-based speed controller is to regulate vehicle speed according to the current speed of the vehicle and the distance between the vehicle and the object in front of the vehicle. The fuzzy controller has developed under three main parts as Fuzzification, Rule base, and Defuzzification. Two inputs were taken to the FLC as ‘Speed error’ and the ‘Distance between vehicle and object Infront’. 49 Fuzzy rules were designed for the fuzzy logic controller in the rule base. The ‘Centroid method’ was used as the defuzzification method. The ‘Mamdani’ system which employs fuzzy sets in the consequent part was used in the Fuzzy logic controller. When the speed and the distance were given, the Fuzzy Inference system gives the best matching fuzzified values as the output value. Then it sends to the motor controller. The results show that the fuzzy logic has minimum transient and steady-state parameters, which show that FLC is more efficient. Finally, the Fuzzy controller produces the responses with little high rise-time, but it offers a high percentage exceed and peak amplitude which can result in poor performance of the system.

    Impact of Perceived Service Customization on Building Customer Loyalty with Mediating Effect of Trust and Perceived Effective Communication (With Special Reference to Automobile Maintenance Service Sector in Sri Lanka)
    (Uva Wellassa University of Sri Lanka, 2020) Madhushani, T.M.S.; Fasana, S.F.; Rajapaksha, R.M.M.C.
    Lack of academic and theoretical knowledge about perceived service customization among front line employees of small size automobile repair centers is one of the main problems of the automobile maintenance service sector in Sri Lanka. The underpinning theory reveals how and why customer relationship marketing connects with customer loyalty. To bridge the knowledge and empirical gaps in existing literature, this study was carried out to investigate how the impact of perceived service customization on building customer loyalty with the mediating effect of trust and perceived effective communication in automobile maintenance. The study was based on a quantitative research approach that was carried out with 312 customers selected using stratified and convenience sampling methods from the western province. Data were collected through a structured questionnaire and analyzed by using Partial Least Square-Structured Equation Modeling and Statistical Package for the Social Sciences. Descriptive statistics, coefficient of determination, specific indirect effect, average variance extracted, and bootstrapping were used to analyze the data. The findings manifested that perceived service customization significantly impacted on customer loyalty with a positive partial mediation between the relationship with trust and perceived effective communication. The study provided perceived service customization with precious implications to enhance the relationship with customers. This study suggests future research based on other underpinning virtues with perceived service customization and customer loyalty in different service sectors. Also, it will help to gain loyal customers in the long run. Keywords: Perceived service customization, Customer loyalty, Customer trust, Perceived effective communication
