Pricing for Complementary and Substitute Products Simultaneously in the Package-Sale and Separate-Sale

Abstract

In this article, the authors present a model for the pricing of a substitute and complementary products (four commodities) while the seller delivers the products individually, in the form of a package to the final customer, and compares the profits from the sale of each scenario. Also, a comparative study has been completed. In the package sale, two complementary products are delivered in one package, but each item is sold in separate sales. The demand function for each product is a function of the price. To illustrate the validity of the model, numerical examples have been used and a sensitivity analysis has been done on the important parameters in the problem.
