Enterprises need continuous product development activities to remain competitive in the marketplace. Their product development process (PDP) must manage stakeholders’ needs – technical, financial, legal, and environmental aspects, customer requirements, Corporate strategy, etc. -, being a multidisciplinary and strategic issue. An approach to use real option to support the decision-making proces...

Product development process (PDP) is one of the most important business processes for enterprises but it has difficulty in workflow management because of the uncertain and dynamic characteristics. Thus, even though there have been many workflow modeling and management methods, they have limitations to deal with the special characteristics of PDP. We define PWF-nets based on timed colored Petri ...

This paper proposes the integration of two systems engineering analysis tools, the Design Structure Matrix (DSM) and Network Analysis (NA), to study task interactions in a Product Development Process (PDP). The DSM is a matrix-based systems engineering tool that analyzes task sequences to improve PDP execution. Using NA metrics to measure properties of information flow helps to identify importa...

This article addresses the ability of Parallel Distributed Processing (PDP) networks to generate stagewise cognitive development in accordance with Piaget’s theory of cognitive epigenesis. We carried out a replication study of the simulation experiments by McClelland (1989) and McClelland and Jenkins (1991) in which a PDP network learns to solve balance scale problems. In objective tests motiva...

UNLABELLED We have developed a program for automatic identification of domains in protein three-dimensional structures. Performance of the program was assessed by three different benchmarks: (i) by comparison with the expert-curated SCOP database of structural domains; (ii) by comparison with a collection of manual domain assignments; and (iii) by comparison with a set of 55 proteins, frequentl...
