Cohesim assesses the use and occupancy rate of the pig building chain, according to management rules (batch segmentation), housing capacities and specifications. Possible technical levers to improve the situation are proposed and evaluated, through simulation scenarios based on precise technical and economic figures.

First, a diagnosis in the coherence of the building chain is led (module 1): Cohesim checks the compliance with density recommendations in post-weaning (module 2) and fattening (module 3).

In case of inconsistency, several scenarios are proposed to optimize the system (module 4):

- Selling piglets (at weaning or at the end of post-weaning),

- Reducing the number of sows,

- Building the missing places,

- Changing lines in pig breeding.
