Abstract: The objective of the present research is to build an empirical Lotka-Volterra system using real-time data and information from two telecommunication service providers of Sri Lanka. The temporal change in market share of the two service providers was modelled by logistic population growth equation of which the coefficients were used as initial values to developing the competition system. Results show that the mobile telecom service providers and the fixed telephone service providers of Sri Lanka are in the process of reaching long-run stable coexistence equilibrium where they would own 83% and 17% shares of the market, respectively. The experimental procedure applied in the present research shows a path to linking mathematical models and economic theories with real-time information to build empirical models that address contemporary issues in life sciences for decision making.
