- the invention offers a solution to the problems mentioned above and makes it possible to significantly reduce the duration of each secondary development cycle, by proposing a three-dimensional numerical modeling method for components making it possible to capitalize the design work and the calculation time.
- An aspect of the invention therefore relates to a three-dimensional modeling method of a component, the method comprising the following steps:
- each three-dimensional reference model modeling a component, each component having a list of technical characteristics
- the three-dimensional modeling method according to one aspect of the invention may have one or more complementary characteristics. among the following, considered individually or in any technically possible combination:

- FIG. 4b shows a second schematic representation of the digital modeling device in three dimensions according to one aspect of the invention.
- Figure 2 is a flow diagram of a three-dimensional modeling method according to one aspect of the invention.
- the flow diagram of Figure 2 has several phases.
- a first phase Ph1 is the identification of recurring components and the inventory of the technical characteristics associated with each recurrent component.
- Each recurring component has at least one technical characteristic.
- the term "recurring component" means a component that has to be modeled and then manufactured several times generically.
- a recurrent component is for example a seat.
- Absolute location of a recurring component within an environment is understood to mean that there is a condition for positioning a given recurring component with respect to an environment, for example an aircraft cabin or a compartment train, regardless of any other elements of the environment.
- the dimensions of the environment are known. For example, if the recurring component is a seat and the environment is an airplane cabin, the absolute seating feature of the seat relative to the aircraft cabin can be written as: “the seat is at inside the aircraft cabin ". The dimensions of the seat are therefore limited by the dimensions of the aircraft cabin. If the recurring component is now a "window seat in a row comprising two seats", the possibilities of locations of said seat within the aircraft cabin are specified and restricted.
- the set of technical characteristics of each recurrent component presents a first variability.
- the first variability can in particular be a range of allowed values and / or an interval of excluded values. This first variability ensures the functionality of the recurring component considered.
- Each recurring component has one or more functions. "Functionality" of a recurring component means that its function or functions are assured. In the case of a seat, a function is: "to allow a passenger to sit down”. The functionality of the seat is ensured when its dimensions effectively allow an average user to sit there.
- the first variability typically determines a range of possible values for the height of the seat relative to the floor, and for the width and depth of the seat considering the average size and body of a user.
- the first variability is intrinsic to each recursive component; in other words, the first variability of a given recurrent component takes into account only the functionality of said recurrent component, independently of any other recurring components.
- a hierarchy can advantageously be established between said first and second technical characteristics.
- the Hierarchy determines an order in which the technical characteristics must be processed to establish the first variability.
- a behavior of the first technical characteristic according to the second technical characteristic and / or a behavior of the second technical characteristic according to the first technical characteristic can be determined.
- a second phase Ph2 is the development, for each recurrent component identified in the first phase Ph1, of a set of rules that determines a second variability for all the technical characteristics of each recurrent component.
- the second variability may especially be a range of allowed values and / or an interval of excluded values.
- the set of rules determining the second variability of all the technical characteristics of each recurrent component advantageously takes into account the spatial environment of the recurrent component considered.
- the position of a first component with respect to a second component may for example be constrained by a rule of the type: "the first component must be placed in contact with the second component ", or” such distance, measured along such a direction, must separate the first component from the second component ".
- the rule set has a first subset of rules specific to a given technical domain.
- This first subset of rules includes in particular the security rules of said technical field, for each recurring component.
- the safety rules relating to a recurrent component of the "seat" type are not, for example, the same, depending on whether one considers the technical field of aeronautics, the technical railway field or the technical field of the automobile.
- the first sub- The set of rules specific to a technical field advantageously comprises all the rules whose compliance is necessary to obtain a certification in this technical field for each recurrent component or combination of recurring components.
- the second variability of all the technical characteristics of each recurring component thus guarantees the certifiability of each recurring component.
- the certification step of a recurrent component is advantageously taken into account and integrated from the genesis of said recurrent component.
- the rule set may advantageously comprise, in a complementary manner:
- the various trades in the technical field are typically: the OPS operator profession, the OEM aircraft manufacturer business, the OEM business and the CCC specialist business. .
- OPS operator profession For a given recurring component, for example a seat, each job thus presents a unique approach.
- An operator manages in particular the general arrangement of components within an aircraft cabin.
- the operator is particularly interested in the positioning of the seat within the aircraft cabin, and the dimensions of the seat.
- An aircraft manufacturer ensures the integration of each component, especially for water inlets, electrical interfaces, ergonomics.
- An equipment manufacturer responsible for manufacturing a component, accesses information about the structure, composition and materials used for this component.
- a first actor and a second actor can differentiate themselves by specific requirements, for example of aesthetic order, which form the third set of specifications.
- a third phase Ph3 is the realization for each recurrent component identified during the first phase of an object, or reference numerical model.
- the reference numerical model of a given recurring component is made taking into account, on the one hand, the technical characteristics of this recurrent component, inventoried during the first phase Ph1, and, on the other hand, the set of rules developed for this purpose.
- recurrent component in the second Ph2 phase the numerical model of reference of a given component determines a third variability for all the technical characteristics of this recurrent component.
- the third variability can be seen as the intersection of the first variability and the second variability.
- the third variability of a recurring component thus guarantees:
- each numerical reference model of a recurrent component is also called "elasticity".
- elasticity The third variability of each numerical reference model of a recurrent component.
- several distinct implementations of the same recurring component are potentially included in a single reference numerical model, each distinct embodiment satisfying the functionality and certifiability requirements; two distinct embodiments typically having differences in their dimensions and their positioning with respect to an environment, within the limit allowed by the elasticity.
- a numerical model of reference of a recurrent component can thus be seen as a matrix of this recurrent component.
- a fourth phase Ph4 is the generation, from a reference digital model of a recurrent component, of at least one particular digital model of this recurrent component.
- Each particular digital model is a separate realization of the recurring component.
- a particular numerical model of a recursive component is typically obtained by selecting a value for each technical characteristic of said recursive component, the choice of each value being restricted by the third variability, or elasticity, of the reference numerical model of said recurrent component.

- the user can therefore authorize the use of a technical characteristic, for example by choosing and activating said technical characteristic from a list of technical characteristics.
- the user can prohibit the use of a technical characteristic, for example by deactivating said technical characteristic from a list of technical characteristics.
- the user determines the degree of automation of the numerical modeling method according to one aspect of the invention. The greater the number of technical characteristics allowed, the greater the degree of automation.
- the first, second and third variabilities are subsequently established for the technical characteristics that were allowed in this substep; - in the case where at least a first technical characteristic and a second technical characteristic are authorized, a sub-step of establishment of a hierarchy between said first and second technical characteristics, that is to say of a rule of priority between said first and second technical characteristics.

- An exchange of data can advantageously be an exchange of particular digital model files between several people of the same user team, and / or between a user and a client of this user.
- the exchange of data is advantageously regulated, that is to say subject to certain conditions: exchanges respecting these conditions are allowed; exchanges that do not respect these conditions are prohibited;
