Abstract

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

Dependency and Structure Modeling (DSM) originates from the methods that have come about from using the Design Structure Matrix and similar methods (matrix-based as well as graph based). These methods have proven very valuable in designing complex systems, optimizing technical systems and product architectures and organizations, densely networked processes and large market structures. With its ability to manage complexity by looking into the structure of a system, it has led to many other advances...
