Improving Learning in Business Simulations with an Agent-Based Approach
By: Márcia Baptista, Carlos Roque Martinho, Francisco Lima, Pedro A. Santos, Helmut Prendinger, Volume 17 (3)
Abstract: Artificial society simulations may provide unprecedented insight into the intricate dynamics of economic markets. Such an insight may help solve the well-known black-box dilemma of business simulations, where designers prefer model concealment over model transparency. The core contribution of this work is an agent-based business simulation that models the marketplace as an artificial society of consumers. In the simulation, users assume the role of a store owner playing against an artificial intelligence competitor. The simulation can be accessed via a graphical user interface that animates ...

Fuzzy Logic for Social Simulation Using NetLogo
By: Luis R. Izquierdo, Doina Olaru, Segismundo S. Izquierdo, Sharon Purchase, Geoffrey N. Soutar, Volume 18 (4)
Abstract: Fuzzy Logic is a framework particularly useful to formalise and deal with imprecise concepts and statements expressed in natural language. This paper has three related aims. First, it aims to provide a short introduction to the basics of Fuzzy Logic within the context of social simulation. Secondly, it presents a well-documented NetLogo extension that facilitates the use of Fuzzy Logic within NetLogo. Finally, by providing a concrete example, it shows how researchers can use the Fuzzy Logic extension to build agent-based models in which individual agents hold their own fuzzy concepts and use t ...

Product Diffusion Using Advance Selling Strategies: An Online Social Network Perspective
By: Peng Shao, Ping Hu, Volume 20 (2)
Abstract: This study analyzes the diffusion of two product types using an advance selling strategy from a social network perspective. We extended the susceptible-infected-removed (SIR) model by adding a buyer component (SIRB) to the model and conducted an in-depth analysis of transmission probability and purchase probability when using an advance selling strategy. Agent-based simulation indicates that cost reduction and promotional effort have positive effects on profits, while lead time negatively affects them. Statistical analyses indicate that lead time has a U-shaped relationship with profits for no ...

Mamdani Fuzzy Systems for Modelling and Simulation: A Critical Assessment
By: Segismundo S. Izquierdo, Luis R. Izquierdo, Volume 21 (3)
Abstract: Fuzzy logic presents many potential applications for modelling and simulation. In particular, this paper analyses one of the most popular fuzzy logic techniques: Mamdani systems. Mamdani systems can look particularly appealing because they are designed to incorporate expert knowledge in the form of IF-THEN rules expressed in natural language. While this is an attractive feature for modelling and simulating social and other complex systems, its actual application presents important caveats. This paper studies the potential use of Mamdani systems to explore the logical consequences of a model ba ...
