WP6.1: Conception and implementation of the MicMac environment using the RECORD platform

The MicMac modelling environment will be developed using the RECORD software platform, which is particularly well suited for projects where model linkages are essential.

The RECORD platform is currently used at INRA by different research teams and provides functionalities for modelling and linking dynamic models based on different approaches (difference equations versus differential equations for instance). It also provides some ancillary features necessary for studies based on simulations, such as statistical methods and data management.

Task 6.1 consists of three actions:

1. Design and implementation of the MicMac modelling environment as a generic dynamic simulation system composed of different sub-models working at the field scale.

These sub-models can either be coded directly in C++ for the modelling environment, or can be pre-existing models developed in various languages (e.g. C, C++, and FORTRAN) that are encapsulated in order to be compatible with the modelling environment.

2. Extension of the MicMac modelling environment to a regional scale.

Many environmental or agronomic problems must be studied at a regional scale and require taking into account interactions among fields. For instance, collective disease management requires consideration of spore dispersal between fields (Aubertot et al., 2006).

A generic structure to represent the spatial distribution of cropping systems and interactions among fields will be developed as part of a PhD thesis (April 1st 2009-March 31st 2012).

3. Statistical or numerical methods related will be implemented in the RECORD library.

In order to carry out the economic evaluation of tested cropping practices within the MicMac project, a linkage with the GAMS software is envisaged.

Various partners take part in this task: BIA and AGIR units (INRA Toulouse), Agroclim unit (INRA Avignon) and Agro Impacts unit (INRA Laon).
