System Simulation Model

WHAT KIND OF TOOL IS IT?

It is a technical simulation model of the coastal zone built using Stock and Flow modelling software (Stella Architect).

WHAT ARE THE DIFFERENT PARTS TO IT?

The System Simulation Model consists of a downloadable file that can be opened in Stella Architect software, and an Excel spreadsheet containing data for the model, and a user manual.

WHAT DOES IT DO?

The System Simulation Model quantifies interactions between activities on land (such as farming and urban development), activities on water (such as fishing), coastal ecosystems (such as coral reefs and mangroves) and coastal resources (such as fish). It allows the user to simulate the behaviour of the coastal system over time.

HOW DOES IT WORK?

The System Simulation Model runs in Stella Architect. The user can create an interface to run scenarios and produce graphs for any variable within the model. It can be used for policy evaluation. For instance, it might be used to assess the impact of land use zoning policies on fish habitat and fish catch, or the impact of fishing management policies (such as a cap on boat numbers) on fish catch and fish price.

WHEN IS IT USED?

The System Simulation Model is intended for technical users, such as governments and universities. It can be used for policy evaluation. For instance, it might be used to assess the impact of land use zoning policies on fish habitat and fish catch, or the impact of fishing management policies (such as a cap on boat numbers) on fish catch and fish price.

IN WHAT FORMAT IS IT AVAILABLE?

The System Simulation Model consists of a Stella Architect file, an Excel spreadsheet and a PDF of a user manual.

WHO IS THE TARGET END-USER?

  • Government departments involved in system simulation for coastal resource management
  • Educational institutions conducting research on coastal systems or teaching courses in coastal systems or system dynamics

WHAT USER SKILLS ARE REQUIRED?

An understanding of Stella Architect is required to use the System Simulation Model. If users seek to modify the tool, an understanding of system dynamics modelling is required.

WHAT IS THE COST OF USING THE TOOL?

The System Simulation Model is available free of charge, under the user agreement and terms and conditions on CCRES website (www.ccres.net), however users must hold a licence for Stella Architect - visit www.iseesystems.com

IS TECHNICAL TRAINING OR SUPPORT REQUIRED?

Users may require technical training in systems dynamic modelling and Stella Architect. If users want to modify the System Simulation Model, training in systems dynamic modelling is required.
