This paper describes a simulation-based decision support system (DSS) to production control of a stochastic flexible job shop (SFJS) manufacturing system. The controller design approach is built around the theory of supervisory control based on discrete-event simulation with an event–condition–action (ECA) real-time rule-based system. The proposed controller constitutes the framework of an adap...

In order to provide Quality of Service (QoS) in open and unpredictable environment, Feedback based Control Scheduling Algorithm (FCSA) is designed to keep the processor utilization at the scheduling utilization bound. FCSA controls CPU utilization by assigning task periods that optimize overall control performance, meeting deadlines even if the task execution time is unpredictable and through p...

Co-design tools represent an effective solution for reducing costs and shortening time-to-market, when System-on-Chip design is considered. In a top-down design flow, designers would greatly benefit fiom the availability of tools able to automatically generate test sequences, which can be reused during the following design steps, from the system-level specification to the gate-level description...

We report on our experience with integrating and using graphics processing units (GPUs) as fast parallel floatingpoint co-processors to accelerate two fundamental computational scientific kernels on the GPU: sparse direct factorization and nonlinear interior-point optimization. Since a full re-implementation of these complex kernels is typically not feasible, we identify e.g. the matrix-matrix ...

High-power-density alcohol fuel cells can relieve many of the daunting challenges facing a hydrogen energy economy. Here, such fuel cells are achieved using CsH2PO4 as the electrolyte and integrating into the anode chamber a Cu-ZnO/Al2O3 methanol steam-reforming catalyst. The temperature of operation, 250°C, is matched both to the optimal value for fuel cell power output and for reforming. Peak...

Mounting degradation in the environmental quality (EQL), specifically from transport industry, is a big threat and challenge for sustainable development. The sector’s emission has gained researchers’ attention on climate change transportation because of its increasing share global emission. This study, thus, aims to analyze links among road infrastructure (RIN), energy consumption (RTEC), with ...

Co-references are traditionally used when integrating data from different datasets. This approach has various benefits such as fault tolerance, ease of integration and traceability of provenance; however, it often results in the problem of entity consolidation, i.e., of objectively stating whether all the co-references do really refer to the same entity; and, when this is the case, whether they...

While collaborative product development (CPD) is adopted by more and more firms as a business strategy, there is still lack of thorough research on the conditions under which the collaboration is formed. This paper proposes a mathematical model integrating trust, coordination, co-learning, and co-innovation dimensions of CPD. These dimensions, as well as additional parameters such as knowledge ...
