Abstract

The Iranian Research Institute for Information Science and Technology (IranDoc) aims to commercialize its research achievements and maintain user satisfaction with its system services. One of these systems is Hamanandjoo, which assesses the similarity of research reports from universities across the country. The various service markets of this system are divided into two main categories: the exclusive market, including proposals, theses, and dissertations, and the multipolar market of journals. The goal of this research is to present a pricing model for the Hamanandjoo system using game theory. In this regard, the potential demand and the importance of competitors in each market are identified, and appropriate pricing strategies for each market are determined. These strategies should be designed in such a way that considering the competitive advantage of the system, the achievable market share is in an optimal state, and ultimately, the profit from the system’s services is maximized. The demand for services is a function of potential demand and service prices, such that with an increase in price the demand for services will decrease, and in the multipolar market, it will also depend on competitors’ prices, so that with an increase in competitors’ prices, the demand for services will increase. The type of competition considered in various exclusive and multipolar markets, given the equal decision-making power of the players is simultaneous competition (Nash equilibrium). In this research, a mathematical model for the players is considered, and the unique Nash equilibrium point is obtained by accurately estimating the parameters of the mathematical model. One of the most important results of this research is the impact of increasing potential demand and the price elasticity coefficient on increasing profit and demand, such that with an increase in potential demand, both the price and the final profit of the system increase and on the other hand, with an increase in the price elasticity coefficient, the final profit of the system and the service prices decrease. In other words, with a more competitive market, the price of providing services will decrease. These findings highlight the importance of considering market factors and competitors in determining pricing strategies for software services.
