Abstract In response to rapidly changing market and customer needs, product design development (PDD) is evolving into a human-centred data-driven paradigm. The environment gets more open often involving crowdsourcing the process becomes complex, considering family along whole lifecycle development, needing data support. Therefore, it critical effectively capture, share, manage design-related in...

An algebraic method for constructing A-optimal designs for two parameter generalized linear models is presented. It gives sufficient conditions to identify the A-optimal design. When the conditions are satisfied, the A-optimal has exactly two points, which is symmetric but not weight symmetric. The methodology is illustrated by means of selected examples. This result proves the conjecture of Ma...

In model-driven engineering, most problems are solved using model transformation. However, the development of a model transformation for a specific problem is still a hard task. The main reason for that is the lack of a development process where transformations must be designed before implemented. As in object-oriented programming, design patterns can benefit “good design” of model transformati...
