Abstract

The purpose of this article is to analyze the optimization strategy of inventory management, considering the possibility of deferred payments, delays in receiving revenue and vehicle capacity restrictions. The study is based on the modification development for the multiproduct EOQ-model that acknowledges the following factors: 1) the time value of money; 2) the possibility of deferred payment negotiated prior to placing an order; 3) specific nature of incoming payments with receipt of revenues from goods subsequent to their delivery; 4) the vehicle capacity; 5) the case of a company paying for its orders with revenues from the goods delivered. This article establishes sufficient conditions to be imposed on the length of deferred payment for the order and the acceptable delay in payment for goods making it possible to form required payments from the proceeds.

Keywords:
