Distance MSc in Operational Research - System Dynamics

Credit Value: 6
Tutors: Susan Howick

Class description/introduction

The class begins with an introduction to what System Dynamics (SD) is and how it can be used. A complete approach to SD modelling is then covered in detail. The behaviour of various systems, in particular complex business problems, are examined through the construction of causal loop diagrams. The class then goes on to introduce computer software used specifically for SD modelling. After familiarisation with the package, students will be expected to use it to model and investigate a variety of systems. In particular, the class will explore how such models can be used to investigate complex business problems and how they can be used to decide upon managerial actions that should be taken to help alleviate the problems.

Class aims

To introduce students to SD. This technique is used to help provide understanding about complex systems through the construction of qualitative diagrams and quantitative simulation models.

Learning outcomes

Subject specific knowledge and skills

• To be able to determine the type of systems whose behaviour can be investigated using SD;
• To develop an understanding of the elements involved in the basic construction of a causal loop diagram;
• To appreciate how a verbal description of a system can be translated into a causal loop diagram and used to examine the system's behaviour;
• To appreciate how a causal loop diagram, representing a given system, can be translated into a quantitative SD model;
• To develop an understanding of the procedures used to validate a SD model;
• To appreciate the process by which SD models can be used to investigate systems behaviours so that practical recommendations can be made to help improve the system;

Cognitive abilities and non-subject specific skills

The learning activities are designed within the class to develop the students within the following areas:

• Problem structuring skill
