Work-package 6

Design and implementation of the « MicMac modelling software environment »


The aim of this work-package (WP6) is to develop a generic software environment dedicated to the design and the evaluation of the agronomic, economic and environmental performances of crop management plans and cropping systems.

The first objective of this work package is to conceive the conceptual framework of this environment and, in a second phase, to implement this «MicMac modelling software environment» using the RECORD platform (

This environment will help develop reusable modelling structures that represent the agronomic, environmental, and socio-economic performances of cropping systems or crop management plans. Hence, the three components of sustainability will be quantified ex-ante (prior to any field experiment) using various models embedded within the MicMac modelling and simulation software environment.

Four types of components of the modelling environment are already foreseen:

- a set of different modules corresponding to models in different domains that are used in the MicMac project to simulate cropping systems:

  •  • decision models used to represent cropping practices in a given field or in a given farm
    • biophysical models that simulate crop and soil processes in cropping systems
    • epidemiological models sensu lato that represent the dynamics of pest populations (plant pathogens, weeds and animal pests) and related damage
    • environmental models that represent the environmental performance of the simulated cropping system or crop management plan
    • models that calculate socio-economic performances

- a simulation engine that allows the linkage of the different models listed above and drives the simulation process

- a module that monitors exchanges with underlying databases

- a set of statistical or numerical methods to help estimate parameters, perform sensitivity analysis, evaluate the predictive quality of the linked models.

The second objective of this WP is to develop methods of software engineering, mathematics and statistics dedicated to the design of cropping systems or crop management plans using the MicMac modelling environment.

Two main features will be developed:

- virtual experimental design and analysis for testing cropping systems or crop management plans

- optimisation algorithms to identify optimal strategies for different multicriteria objectives, and under multiple constraints.

The work-package 6 is split into 4 tasks:

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

- WP6.2:Design and software implementation of crop management plans and cropping systems and mathematical optimisation of strategies

- WP6.3: Methods for parameter estimation and evaluation

- WP6.4: Development of a specific database for the field experiments conducted in the MicMac project and linkage of the models embedded within the MicMac platform to the database
