Wide diffusion of methodologies and software relevant to Product Lifecycle Management (PLM) in industrial companies faces heterogeneity of information technology (IT) systems. Especially, the lack of interoperability between Product Data Management (PDM) systems, that drive virtual product development, and Enterprise Resource Planning (ERP), which manages real product, cannot lead to a global d...

Wide diffusion of methodologies and software relevant to Product Lifecycle Management (PLM) in industrial companies faces heterogeneity of information technology (IT) systems.

In the lean construction philosophy, the management of constraints is essential to reduce project delays. These constraints can be derived from construction requirements which define the characteristics of the construction project. This paper discusses the evolution and classification of requirements. Additionally, a framework to semantically map the construction requirements to schedule constr...

‘Human factor’ is one of the most relevant and crucial aspects of software development projects management. Aiming at the performance improvement for software processes in organizations, a new model has been developed to diagnose people related processes. This new model is People-CMM and represents a complementary solution to CMM. On the other hand, existing estimation models in Software Engine...

Product distribution matching (PDM) is proposed to generate target distributions over large alphabets by combining the output of several parallel distribution matchers (DMs) with smaller output alphabets. The parallel architecture of PDM enables low-complexity and high-throughput implementation. PDM is used as a shaping device for probabilistic amplitude shaping (PAS). For 64-ASK and a spectral...

Distributed and collaborative data stream mining in a mobile computing environment is referred to as Pocket Data Mining PDM. Large amounts of available data streams to which smart phones can subscribe to or sense, coupled with the increasing computational power of handheld devices motivates the development of PDM as a decision making system. This emerging area of study has shown to be feasible ...

Reducing the time for engineering changes can greatly shorten a product’s life cycle and improve the productivity of enterprises. This work proposes an approach to engineering change propagation between CAD and product data management (PDM) systems. A system for modeling and triggering changes of models of engineering data, geometries, and features, using STEP AP 214 and AP224, is developed. A ...

A mechatronic system is a synergistic integration of mechanical, electrical, electronic and software technologies into electromechanical systems. Unfortunately, mechanical, electrical, and software data are often handled in separate Product Data Management (PDM) systems with no automated sharing of data between them or links between their data. Presently, this is a significant drawback with reg...

Received: 5 February 2011 Abstract Accepted: 7 April 2011 The paper presents the trends in the development of methods and systems for manufacturing and assembly process planning on the background of Concurrent Engineering strategies. The solutions for the functional integration of design/manufacturing and production preparation phases and the IT infrastructure including PDM systems for the stor...

The polarization-division multiplexing (PDM) technology is a practical method to double the transmission capacity, and the corresponding phase regeneration (PR) for PDM signals is meaningful and necessary to extend the transmission distance and increase the transparency for the phase-encoded PDM system. Those reported PDM PR schemes either utilized polarization-diversity technique or required s...
