Sales and operations planning: the supply chain pillar

Abstract

In the present ever-changing environment, sales and operations planning (S&OP) is a key process for providing visibility to the enterprise. Besides, it supports a transversal decision process, which co-ordinates different functions either in the company or between companies, in a supply chain (SC) environment. In the literature, S&OP models are mainly focusing on sales, production and inventory. This paper proposes a wider S&OP model built with three levels (sales, operations and supply). It provides a better support for integration inside the company, but also for integration of the company in the SC. Some simulation results are presented, describing the S&OP propagation along a SC, and the related collaboration requirements to be satisfied between the networked companies.
