We developed recently a new and novel student project allocation model (SPA-(s, p)) in which the lecturers have preference lists over pairs (student, project), and the students have preference lists over projects. SPA-(s, p) is turned out to be very useful in combination between the student project allocation models with preference lists over students (or projects) [8, 9]. SPA-(s, p) proposes several ways to construct the lecturer's preference lists which give us higher efficiency and accurate results. This study presents new data structure which reduces the space to present an instance of SPA-(s, p). Furthermore, this study presents a visualization of SPA-(s, p) model. The visualization is implemented in java for the fact that it is a web-oriented language.
