An example of the user interface of the system that has been developed to
simulate the localization problem of shopping centers in the area of Bergamo (Italy)
introducing some constraint, a MRDM collapses to a standard CA. The MRDM
has been implemented on two different computer architectures. The first imple-
mentation realizes a CA based model described in terms of MRDM has been
developed on a Cray T3E and Origin S2000 parallel computers. It provides an
environment suitable to simulate complexsystems of physical and chemical na-
ture: specifically, the domain concerns transportation phenomena occurring in
the percolation processes of pesticides through soils. The parallel implementation
has been chosen because of the high computational demand of the model [19].
The second implementation, realized in Java(
TM
), provides an environment suit-
able for cooperative applications supporting awareness. The main feature of this
implementation concerns the possibility to model different forms of interactions
occurring on different layers and on a single layer, allowing significant aspects of
the awareness model to be represented and computed [16]. An additional applica-
tion of the MMASS approach to model and simulate complexsystem dynamics in
the theoretical immunology domain is currently under design. Within a project
funded by the Italian Ministry for University and Research ('Cofinanziamento
Programmi di Ricerca di Interesse Nazionale'), the analysis of a previously pro-
posed modelling and simulation approach based on Cellular Automata [20] will
be continued by exploring the possible benefits deriving from the adoption of
the MMASS approach.
Finally, it is under design a support tool for designing, developing and run-
ning applications based on the MMASS model. The aim of the project is to
