Economic order quantity model for two generation consecutive technology products under permissible delay in payments

In this article, we discussed optimal replenishment policies for two succeeding generations' technology products under partial trade credit financing. It is often seen that in market, advanced generation product plays an important role cannibalising the market of existing product. Thus, precise estimation demand critical taking any policy decisions. Demand a complex process, as consumer buying behaviour generational not only depends on marketing mix variables but also associated with time-to-market phenomenon new technologies. interaction among users different controls rate substitution older one. Therefore, due to nature multi-generation product, it incorporate interaction-substitution effect kind products. We used life cycle dynamics project rates generations. paper, formulate total cost function five situations depending upon introduction timing and length period. A detail sensitivity analysis been performed explore efficacy model given situation.
