DYNAMIC MULTI-AGENT BASED VARIETY FORMATION AND STEERING IN MASS CUSTOMIZATION riety steering. Based on the decision theory’s model for rational agents, we formally define the function that an agent strives to optimize. The negotiation process between the intelligent agents is based on the target costing concept and a Dutch auction. This is also described in a formal way defining the possible functions which have to be determined. Because we intend to carry out simulations of the entire system, several functions which determine the intelligence of the defined agents should be tested. Based on these simulations we will decide which implementation will lead to a working prototype. Furthermore, a technical architecture for the agentbased variety formation and steering in mass customization is proposed. The main advantages of the developed approach are the easy maintenance of the system, the dynamic variety generation and variety steering, as well as the application of a market mechanism concept supported by agent technology. The adopted market mechanism presents a relevant approach enabling one to overcome the shortcomings of existing interaction systems and variety steering methods. Thus, instead of building rigid rules in the interaction system that map customer requirements into product attributes, the proposed market mechanism approach lets the intelligent agents themselves decide according to the current situation about their suitability to fulfill real customers’ requirements. Furthermore, the market mechanism enables us to connect two relevant concepts in mass customization, namely which product variants should be retained in the product assortment and which specific ones from this assortment should be selected and offered to a particular customer.
