Abstract
Today, informational structure is organized in such a way that sellers can easily employ the various capabilities of social networks, such as the analysis of positive and negative tendencies of neighbours, to maximize diffusion in the network. Therefore, in this paper we employ this approach to introduce a novel mathematical product pricing model for a monopoly product in a non-competitive environment and in the presence of heterogeneous customers. In this model, all customers are divided into various groups based on their preferences for the price, quality and need time for the product demand and also the positive and negative influences of neighbours. So, it seems customers utilize a multi-criteria decision-making model for buying a product. When a customer buys a product and additionally, persuades its neighbours to also buy the product they will receive a referral bonus from the seller. Meanwhile, the intensity of relations between neighbours in the network is incorporated into the model qualitatively. Finally, hardness of the problem justifies application of a genetic algorithm for solving the proposed pricing model and real-world dataset is used to conduct a case study that verifies its applicability.

Notes
Influence and exploit in which a product is offered to a group of customers for free or at minimum price with the aim of taking advantage of the remaining group of customers.
In the social network literature, homophily (heterophily) and assortativity (disassortativity) are applied to indicate positive (negative) correlation between the features of neighbours.
Intensity of relations is the edge weight. It is a qualitative value among strong, mediocre and weak that the new individual scores to indicate their relation with the sender of the form.
