“…Researchers have used the idea of mathematical modelling to solve problems in different fields such as infectious disease in Covid-19 [1,5,6], Malaria [20], Hepatitis B virus [21]. Not only in infectious disease but also in ecology relating to Lotka-Volterra model such as Holling-Tanner model [2][3][4]. The same ideology is employed in the investigation of unemployment within the university and industry sector on the study of PhD graduates and Postdoctoral research fellows.…”

Unemployment poses to be a threat in many countries which has been a long age battle with the human race. Our study considers Africa (South Africa to be precise) and focuses on the academic and industry sectors, with PhD graduates and postdoctoral research fellows as key participants. The movement of PhD graduates and postdocs between academia and industry, and its impact (increase or decrease) in unemployment within the sectors was investigated. For the population of University, PhDs, Postdocs, and industry compartments, a model was developed. The primary objectives investigates the model by analyzing the stability at the University-PhD-Postdoc-Industry free equilibrium, University-PhD-Postdoc-Industry equilibrium, determine the recruitment number R UE and understand how to mitigate migrations within the University and Industry compartments. Our findings help to understand the cause and effects of migration, and aims to manage the migration of PhD graduates and Postdocs moving into the Industry while the university suffers research capacities.
