Equilibrium Model of Discrete Dynamic Supply Chain Network with Random Demand and Advertisement Strategy

Abstract EN

The advertisement can increase the consumers demand; therefore it is one of the most important marketing strategies in the operations management of enterprises.

This paper aims to analyze the impact of advertising investment on a discrete dynamic supply chain network which consists of suppliers, manufactures, retailers, and demand markets associated at different tiers under random demand.

The impact of advertising investment will last several planning periods besides the current period due to delay effect.

Based on noncooperative game theory, variational inequality, and Lagrange dual theory, the optimal economic behaviors of the suppliers, the manufactures, the retailers, and the consumers in the demand markets are modeled.

In turn, the supply chain network equilibrium model is proposed and computed by modified project contraction algorithm with fixed step.

The effectiveness of the model is illustrated by numerical examples, and managerial insights are obtained through the analysis of advertising investment in multiple periods and advertising delay effect among different periods.
