Eurobios OptiMOD enables to find the best optimisation strategy to ease the design of complex industrial products. Thanks to the Multi-Criterias Optimisation capabilities of OptiMOD, design becomes easier, and the global product characteristics are optimised according to the predefined goals (technical or financial ones...).
Optimiser for Multi-Objective Design.
Industrial products design and development optimisation
OptiMOD eases the complex products design by Multi-Criteria Optimisation: OptiMOD applies to design optimisation in draft phase or to industrial components optimisation in development phase.
Difficult trade off in draft phase and final touchy compromises during implementation:
During design phase needs and constraints result from different departments: marketing, product strategy, used technologies, innovations…
Constraints due to internal necessary discussions and agreements.
During implementation phase, difficulties result from taking into account more numerous technical constraints, enclosing or not the innovations and respecting the new standards.
In addition, analysis, development, testing and delivery delays become shorter.
Industrial companies should thus take into account:
Inherent constraints to already made choices,
Customer needs and standards evolution,
The quality and the variable costs of the components used in the product manufacturing,
In this two cases, OptiMOD enables to find by Multi-Criterias Optimisation the best global solutions satisfying at best each of the particular goals.

The successive steps in OptiMOD use are as follows:
Step 1: Definition of the universe (Project, Variables, Relations between variables) Step 2: Model design (Model, Goals, Penalties) Step 3: Choice of the optimisation strategy (accurate Algorithms) Step 4: Execution of the strategy and control (Monitoring) Step 5: Results visualisation and analysis (Graphs and tables).
The different stages of multi-criteria optimisation:
Step 1: Definition of the universe (Project, Variables, Relations between variables), the user starts defining his Projects and his Models. The Project can be a global Project or a specific study.
A Project is composed of:
Variables: The user defines project variables and terminology. He can if necessary import these variables from other CAD environments (i.e. CATIA V5...),
Relations between variables: These relations enable to describe the interdependencies between variables,
Models: The user can use within the same project different models according to the diversity of issues.
The Universe definition includes the definition of the Project variables in a reference table to be used for the various Models.
The type of relations between variables is a critical point. The interface enabling to link the variables is very easy to use and integrates a complete equations editor.
Step 2: Model design (Model, Goals, Penalties). The Model is built by the definition of the Constraints and Goals. In order to obtain the most precise optimisation, the user defines Constraints which by their interaction delimit the feasible Domains of the model. We define then Goals based on the already defined variables as well as Penalties, which contribute to measure the goal achievements. The OptiMOD formal calculator checks instantly the model coherence and helps solving possible problems (i.e. loops).
Step 3: Choice of the optimisation strategy (accurate Algorithms). The seamless capabilities of OptiMOD helps the user in choosing the best optimisation strategies for his Project.
Combining the best algorithms power to quickly find the best solutions,
Discovering by this mean some “hidden“ solutions,
Using algorithms enabling local searches (Simplex, simulated annealing, Gradient) and global heuristics (genetic algorithm, «memetic» algorithm…).
Step 4: Execution of the optimisation strategy and control (Monitoring). The execution of the optimisation strategy and its control are done through an execution Monitor enabling to:
Visualise how OptiMOD progresses towards the optimal solution,
Control graphically if the chosen optimisation strategy is accurate,
Choose to suspend or to end the optimisation if the user considers the results as satisfactory.
Step 5: Results visualisation and analysis (Graphs and tables). For the analysis, the results visualisation is made easy in OptiMOD with the capability to use various charts enabling to compare the solutions found by the tool.
