🗒️[Glossary] Boolean algebra
Boolean Algebra is a mathematical framework used to represent and manipulate logical expressions involving binary variables (true/false). In the context of variant management, Boolean algebra plays a critical role in defining and managing the relationships between product features, options, and constraints.
Role in Variant Management
In product configurators, Boolean algebra can be used to model the rules and constraints that govern the selection of product configurations. These rules ensure that valid combinations of features are created while excluding invalid or incompatible ones. Logical operators such as AND, OR, and NOT are used to define these relationships.
AND (∧): A product feature requires the presence of another feature (e.g., "Sunroof AND Leather Seats").
OR (∨): A product feature can be chosen from multiple options (e.g., "Color is Red OR Blue").
NOT (¬): A feature excludes another feature (e.g., "NOT (Sport Brakes AND Economy Tires)").
Examples
Automobiles:
A car configuration may use Boolean rules to enforce logical constraints:"If the car has a Sunroof, it must also have Reinforced Roof Structure."
"The car cannot have both Sport Suspension AND Economy Tires."
Software Products:
For software with modular features:"If Feature A is selected, Feature B must also be selected."
"Feature C is only available if Feature D is NOT selected."
Consumer Electronics:
"The device can have either a USB-C port OR a Lightning port, but not both."
Important
Boolean algebra simplifies the management of complex product configurations, but it requires careful definition of rules to avoid inconsistencies or unintended restrictions.

In product lifecycle management, describing highly variant products efficiently is key. A "variant space" represents all possible product variations. Constraints define feasible combinations. Simplified visual tools like Euler or Venn diagrams help illustrate and solve real-world challenges effectively.
