Method and system for managing constraint-based violations in a product data management environment

A computer-implemented Product Data Management (PDM) system comprising:

• a processor;
• and
• an accessible memory coupled to the processor, wherein the memory comprises a PDM module configured to:
• obtain a set of constraints defined for a product, the set of constraints comprising one or more families with corresponding values, each family of the one or more families representing a single type of product design option and comprising a group of mutually exclusive values associated with the single type of product design option, wherein each constraint of the set of constraints is associated with a single family and single corresponding value;
• obtain requirement data associated with the product, the requirement data being in the form of an input expression via a graphical user interface of the computer-implemented PDM system, the input expression containing one or more values associated with one or more families of the set of constraints;
• determine constraints that are conflicting with the obtained requirement data associated with the product from the set of constraints when the requirement data is not successfully validated with respect to the set of constraints, wherein a constraint is conflicting when a value of the input expression associated with the single family of the constraint does not match the single corresponding value of the constraint, and wherein at least one constraint from the set of constraints is responsible for causing a violation;
• group the conflicting constraints into a plurality of logical groups based on a type of independent violation, the type of independent violation indicating a specific conflict between a value of a family of a single constraint and a value of a corresponding family of the requirement data for a type of family, each logical group of the plurality of logical groups being associated with a single independent violation, such that the independent violation of a respective logical group represents a single conflict between a value of a family of the obtained requirement data and a value of a corresponding family of the constraint of the respective logical group;
• output a multi-dimensional representation of the plurality of logical groups of conflicting constraints on a first view of a display unit, such that a total number of independent violations is determinable by a user from the first view;
• compute one or more solutions corresponding to each independent violation based on the logical groups;
• automatically resolve conflicts between the constraints and requirement data corresponding to respective independent violations based on the corresponding one or more solutions;
• and
• configure the product based on the requirement data upon resolving the conflicts.

A non-transitory computer-readable storage medium that stores instructions executable by a Product Data Management (PDM) system to manage constraint-based violations associated with a product in the PDM system, the instructions comprising:

• obtaining a set of constraints defined for a product from a product database, the set of constraints comprising one or more families with corresponding values, each family of the one or more families representing a single type of product design option and comprising a group of mutually exclusive values associated with the single type of product design option, wherein each constraint of the set of constraints is associated with a single family and single corresponding value;
• determining constraints that are conflicting with requirement data associated with the product from the set of constraints when the requirement data is not successfully validated with respect to the set of constraints, the requirement data being in the form of an input expression via a graphical user interface of the computer-implemented PDM system, the input expression containing one or more values associated with the one or more families of the set of constraints, wherein a constraint is conflicting when a value of the input expression associated with the single family of the constraint does not match the single corresponding value of the constraint, and wherein at least one constraint from the set of constraints is responsible for causing a violation;
• grouping the conflicting constraints into a plurality of logical groups based on a type of independent violation, the type of independent violation indicating a specific conflict between a value of a family of a single constraint and a value of a corresponding family of the requirement data for a type of family, each logical group of the plurality of logical groups being associated with a single independent violation, such that the independent violation of a respective logical group represents a single conflict between a value of a family of the requirement data and a value of a corresponding family of the constraint of the respective logical group;
• outputting a multi-dimensional representation of the plurality of logical groups of conflicting constraints on a first view of a display unit of the PDM system, such that a total number of independent violations is determinable by a user from the first view;
• computing one or more solutions corresponding to each independent violation based on the logical groups;
• automatically resolving conflicts between the constraints and requirement data corresponding to respective independent violations based on the corresponding one or more solutions;
• and
• configuring the product based on the requirement data upon resolving the conflicts.
