scheduling of multipurpose batch processes with multiple batches of the products

Hungarian Journal of industrial Chemistry 2002年第4期30卷 305-312页

作者： Holczinger, t. Romero, J. Puigjaner, L. Friedler, F. Department of Computer Science University of Veszprém Egyetem u. 10 Veszprém H-8200 Hungary Chemical Engineering Department Univ. Politèc. de Catalunya E.T.S.E.I.B. Diagonal 647 E-08028 Barcelona Spain

Optimal scheduling of batch processes becomes excessively complex if large number of batches of the products has to be generated. in most cases, however, the search space of the optimization procedure can be drastically reduced by eliminating the redundant solutions through additional combinatorial constraints. the proposed approach that generates these additional constraints is described here for a graph-theoretical method for batch process scheduling, nevertheless, it can be conveniently embedded into other methods developed for optimal scheduling.

to study the electronic transport properties of two-dimensional electron gases confined at the interfaces of AlGaN/GaN heterostructures, shubnikov–de Haas (sdH) and Hall measurements were performed with structures covering a wide range of sheet carrier concentrations from 2.25 × 10 12 to 1.83 × 10 13 cm —2 . For samples with sheet carrier concentrations above 1.7 × 10 13 cm —2 , the occupation of a second subband was observed. Fourier transformation was used to separate the contributions of both occupied subbands to the electronic transport. Quite similar quantum scattering times and effective masses of the electrons in the first and second subband were determined. in samples with lower sheet carrier concentration traces of a spin splitting could be found by investigating the angle dependence of the sdH-oscillations.

the fast adoption of iP-based communications for hand-held devices equipped with wireless interfaces is creating new challenges for the internet evolution. Users expect flexible access to internet based services, including not only traditional data services but also multimedia applications. this generates a new challenge for Qos provision, as it will have to deal with fast mobility of terminals being independent of the technology of the access network. Various Qos architectures have been defined, but none provides full support for guaranteed service levels for mobile hosts. this paper discusses the problems related to providing Qos to mobile hosts and identifies the existing solutions and future work needed. © springer-Verlag Berlin Heidelberg 2001.

the practical implementation of the third-order tetrahedral version of Nedelec's first family of curl-conforming elements is presented. Following the definition of the element given by Nedelec, the third-order vectorial basis functions of the element are deduced. the element thus obtained exhibits some important differences with respect to other higher-order curl-conforming elements which have appeared in the literature. specifically, the third-order curl-conforming finite element proposed leads to better conditioned finite element method (FEM) matrices.

the realization of new distributed and heterogeneous software applications is a challenge that software engineers have to face. Logic programming and multi-agent systems can play a very effective role in the rapid prototyping of new software products. this paper proposes a general approach to the prototyping of complex and distributed applications modelled as multi-agent systems and outlines the autonomous research experiences of different research groups from which the approach originates. All the experiences have logic programming as the common foundation and deal with different aspects of the problem: integration of heterogeneous data and reasoning systems, animation of formal specifications and the development of agent-based software. the final goal is joining these diverse experiences into a unique open framework. © 1999 iEEE.

industrial production is one of the main pollution sources. Modern technology design facilitates the development of “Clean-technologies”. A shift towards this new paradigm in production in general is needed. information and communication technologies allow an appropriate information management which supports the integration of such ecological criteria into managerial decision-making. in this report, a case study describes the application of such environment-oriented information management: the clustering of production sites as a sustainable network of modem industrial production and services.
