The concept of cellular automata originates in research by J. Von
Neumann about forty years ago. Nevertheless, marketing applications remain scarce. That's why this paper analyses, with the help of a simulation model, how the use of cellular automata can visualize interactions between consumers and forecast the evolution of markets. The CAMAC model is characterized by an economic space as a bidimensional torus and consumers as multi-state probabilistic cellular automata able to go through as many different states as there are different competing products on the market. Various consumer behaviours are studied: nonconformism, following opinion leaders, sensitiveness to other individuals, brand loyalty, variety search, individual geographic and relational mobility, family size and internal purchase decision processes. Other socio-economic parameters such as the market size, the inter-individual distance, the number of competing products or the kind of goods are introduced. This model is tested and at last its limitations and its interest are pondered.
