Summary: Advertising with salers in supply chain management is very important, for it decides about the profit and the market occupancy. The paper views supply chains as a whole, they sale seasonal production, salers are an independent department and advertise seasonal production. We establish a differential game model to study the action and the effect of advertising, and then give an advertising differential game model. At last, we assume that the cost function and the profit function obey to normal distributions, and give some good results.
