Here is a small collection of papers dealing with technical and conceptual aspects of simulaton and modelling.
The papers are written prior to the development Dynaplan Smia. Smia supports many of the concepts introduced and described in these papers, and adds many more.
Model Interchange Format (1985)
The above two documents proposes a vendor-independent representation of simulation models. It is inspired on the RTF meta format for text documents.
The current Dynaplan Smia file format uses the later XML meta format for representing models.
Smia's file format defines dataflowml (dataflow mark-up language), a common format for data flow languages, such as spreadsheets and dynamic simulation models.
This paper is about the relationship between design patterns in the OO world and components in the SD world.
This paper proposes a range of extensions to the SD modelling technology.
The company I worked for at that time did not choose to implement the object-oriented features of the proposed modelling language.
When I founded Dynaplan a few years later, our first priority was to create an object-oriented language (Dynaplan Smia) for modelling.
The World Model Controversy (2005)
This paper discusses the controversy around the World Model. This controversy was mainly between advocates of econometry and advocates of system dynamics, and in particular: the Club of Rome.
The paper shows that system dynamics and econometry has different, and complementary, characteristics that can be used in combination and isolated to represent different aspects of a problem.
Therefore, it makes perfect sense to create technology, such as Dynaplan Smia, where both econometry and system dynamics are supported.
