Embodiment Construction

[0060] The computer-implemented method according to the present invention is intended for designing an assembly composed of a plurality of objects. The component is modeled by a directed acyclic modeling graph with nodes and arcs. Each node represents an object of that component. Each arc represents the use of the start node to the end node. At least one arc is uniquely identified by an identifier. The component is further modeled by at least one relation having at least one tuple containing a first chain of at least one identifier. The method includes the steps of: determining at least one mapping between a first chain and a second chain consisting of at least one identifier; and replacing at least one occurrence of the first chain with the second chain in a tuple of relations. In this way, disconnected tuples are automatically recovered and design is facilitated.

Abstract

The present invention provides a computer-implemented method intended for designing an assembly of a plurality of objects. The assembly is modeled by a directed acyclic modeling graph having nodes and arcs. Each node represents an object of the assembly. Each arc represents the use of an end node by an origin node. At least one are is uniquely identified by an identifier. The assembly is further modeled by at least one relation having at least one tuple containing a first chain of at least one identifier. The method comprises the step of determining at least one mapping between the first chain and a second chain of at least one identifier as well as the step of substituting at least one occurrence of the first chain in the tuple of the relation with the second chain. The invention provides this way a means to repair broken tuples automatically and thus to facilitate design.

Description

technical field [0001] The present invention relates to the field of design of object components and the field of collaborative design of object components. Background technique [0002] Typical examples of assemblies are: complete automobiles, aircraft, boats, interior and / or exterior of vehicle body structures including mechanical and electronic equipment. This component is designed to give engineers a virtual presence of future products for research and trade-offs. [0003] When designing new components of an object, designers typically work using PLM / CAD systems (ie: Product Lifecycle Management / Computer Aided Design systems). The system includes a database of reference objects, such as pre-stored (or possibly also created and stored when designing new components) components or components composed of components. [0004] Components are modeled by reuse graphs. Reuse graphs (or "reuse" graphs) are labeled directed acyclic graphs that capture the reuse patterns that und...
