The Three Modeling Methods Work Together

In this model the three major modeling methods (Discrete Event, Agent Based, and System Dynamics) are combined and work together.
The supply chain model is built in discrete event way using blocks from AnyLogic Enterprise Library. The supply chain employs a stationary (s,S) inventory policy: whenever the retailer stock falls down to s, the retailer reorders (S-s-expected) products. You can change all parameters of the supply chain on the fly.
The consumer market model is agent based one with agents representing individual consumers. The decision making logic of a consumer includes a system dynamics part that models the dynamic change of consumer's interest in the product and a statechart that models the discrete decisions made by the consumer. The consumer's interest grows when advertising is on, decays over time, and may be lost due to product unavailability. The decisions and events include decision to purchase, purchase, loss of interest, temporary dissatisfaction due to continuous product unavailability, product discards, and contacts between consumers.
Consumers who are using the product spread a word of mouth about it by sending messaged to other consumers. Each such message raises interest in the product. If a consumer wants to buy the product but the product is unavailable for more than a certain period of time, he gets dissatisfied and will only become a potential client if his interest reaches a fairly high level.
