Today, competition among industries has increased because of development of technology, so all industries are seeking to increase their competitive advantages and thereby gain more market share. The pharmaceutical supply chain is not an exception to this, so each competitor should try to find an advantage that is more appealing to the customer. One of these advantages can be the time that the downstream member of the chain can pay after purchasing the products.
In this paper, delay in payment is considered as a competitive factor in the competition between the two suppliers of medicine. So that the supplier who gives more time to his customer, is selected by the customer for order allocation. This involves two objective functions : maximizing the amount of sale for suppliers and minimizing costs for the customer. Indeed, from specific innovations, this is an integrated vision of the supply chain in a competitive environment and a particular competitive factor. The variables obtained by solving this model include the permissible delay in payment and the amount of order allocation to each supplier. Finally, a numerical example and sensitivity analysis on one of the important parameters of the problem is presented.
