In a V-shaped process of model-based development, methods of product information model decomposition from upper processes to lower processes have not yet been established. In this paper,
we defined the diagrams, diagram elements and the design operations that are necessary to support the refinement and Verification and validation (V&V) process of the product information model in two layers, based on methods for refining function structures, product behaviours, constraints, and required specifications step by step. It is shown that design results of tools or methods are reflected and managed by expressing the model information data and design operations in DSM (design structure matrix). Iterative processes and relation analysis using the matrices support the effective refinement process. Also it is proposed that stepwise V&V is supported effectively using the DSM in cooperation with product information models, tools and method for analysis, simulation etc., by demonstrating verification as a method of verifying the design on the model in the lower layer, and validation as a method of evaluating the design in the lower layer for requirements in the upper layer.

Keywords: Verification and validation, model-based development, design structure matrix, design information model
