TLDR
The fundamental concepts behind the use of heuristic optimization as a means of improving the behavior of systems as represented by system dynamics models are presented.Abstract:
This paper presents the fundamental concepts behind the use of heuristic optimization as a means of improving the behavior of systems as represented by system dynamics models. The philosophy of the approach is highlighted and the underlying software explained, as a prerequisite to developing some simple demonstration examples.read more

Automated parameter specification in dynamic feedback models based on behavior pattern features
Gönenç Yücel,Yaman Barlas +1 more
TL;DR: A behavior pattern-based parameter search approach and results obtained from various test experiments reveal the viability of the approach as a support tool that can be used in model calibration, sensitivity analysis, validation, and policy design stages.

An Overview of Strategy and Tactics in System Dynamics Optimization
Brian Dangerfield,Carole Roberts +1 more
TL;DR: A review of the methods and purposes of optimization in system dynamics models is undertaken and it is suggested that an optimization strategy embracing search-based techniques is preferable to one based on optimal control methods.

The use of optimization methods for policy design in a system dynamics model
TL;DR: Routes developed by Keloharju are applied to a simple model of unstable inventory dynamics and policies derived from the optimization approach are compared with policies obtained in earlier, more intuitive analyses to suggest that optimization methods could significantly improve the speed and power of policy analysis in formal models.

System dynamics and heuristic optimisation in defence analysis
TL;DR: In this article, the authors demonstrate the benefits of using optimisation for policy design in system dynamics models by applying it to an existing defence model to design formation change strategies for an attacking force (Red) in response to indirect fire strategies applied by a defending force (Blue).

Solving economic optimal control problems with system dynamics
Hannu Kivijärvi,Markku Tuominen +1 more
TL;DR: This paper presents an alternative method based on system dynamics for solving economic and managerial optimal control problems and can be helpful in cases where the application of the mathematical optimal control theory is impossible or too laborious for planners or decision makers.
