What is System Dynamics Model

Chapter 21
Handbook of Research on Discrete Event Simulation Environments: Technologies and Applications
It’s a computer simulation model based on system dynamics features that aim to confirm that the structure hypothesized can lead to the observed behaviour and to test the effects of alternative policies on key variables over time. Modeling purpose is to solve a problem and also to gain insight into the real problem to design effective policies in a real world, with all its ambiguity, messiness, time pressure and interpersonal conflict. It is a feedback process, not a linear sequence of steps. System dynamics models are very important tools for managers that enable them to design their organizations, shaping its structure, strategies and design rules and enable them to take different decisions in their organizations. It is an effective tool in promoting system thinking in an organization.

Abstract
The Jordanian banks and the risk analysts in particularly are seeking to adapt and buy new analytical techniques and information systems that help in identifying, monitoring and analysing the credit risk especially for the small firms that represents the biggest firms’ base in the Jordanian markets. This chapter supports that what analysts need is a thinking tool that allow the user to simulate, understand and control different policies or strategies. It will then enable better decision to be made. A simulator based on system dynamics methodology is the thinking tool produced by this chapter. The system dynamics methodology allows the bank to test “What If” scenarios based on a model which captures the behaviour of the real system over time. The objectives of this chapter is to introduce new performance measures using systems thinking paradigm that can be used by the Jordanian banks to assess the credit worthiness of firms applying for credit.

Disciplinarily-Integrated Games: Generalizing Across Domains and Model Types
In a system-dynamics model, variables are linked together by positive or negative links. Variables can be increased or decreased, which in turn changes other variables in the system though the links. These models can be qualitative or quantitative. Various lag, homeostatic, or feedback functions can be built into the models.
