In this study, we present an intelligent personalized course advising model by analyzing, selecting, and modifying effective course advising technologies. It overcomes the existing course advising systems by using common design for all Higher Educational Institutes and making the rule, regulations, curriculum, and grading system more flexible to change without affecting persistent academic data. The proposed model helps students by analyzing and suggesting appropriate courses according to their academic history and special interest via harmonized knowledge of different experts. To develop this model, analyze various requirements were gathered and explicitly analyzed from the course advisory systems and other related technologies, that were used in seven institutes. The proposed model contains seven components, in which they use association rule, rule-based expert system, and fundamental recommendation algorithms according to their suitability for collected requirements. We made more modifications and enhancements on those algorithms to achieve the purpose of each component. We used ISO-25010 quality model with the institutional rules and regulations of three departments to evaluate the proposed model. The obtained results showed that the proposed methodology of the model is an effective way to improve the efficiency of students course advisory systems. It also indicates that advisors and students can save more time through effective and efficient course suggestions during the course registration period.
