Flat versus Hierarchical Information Models in PLM Standardization Frameworks

Abstract
Smart manufacturing requires digital product data to be shared and exchanged among numerous engineering applications and information systems. But no single product data standard can satisfy every integration scenario. Customizable standardization frameworks for Product Lifecycle Management (PLM) attempt to address this problem by allowing users to add new information structures to an existing data model in a controlled manner. A PLM information model may be either flat or hierarchical. We use an approach based on ISO 10303-239 as an exemplar for customizing flat models and an approach based on Open Application Group Integration Specification (OAGIS) as an exemplar for customizing hierarchical models. We evaluate the flat versus hierarchical approaches and make two observations. First, the type of model strongly influences how well the framework meets each evaluation criterion. Second, the best choice is use-case dependent.
