Combining genetic programming with generic simulation models in evolutionary synthesis

Abstract In the proposed combined model of the engineering synthesis, the simulation and the parametric design are organized by the genetic building elements, while the genetic possibilities are evaluated by the experiences, obtained from the detailed dynamic simulation. Using this methodology, a new, integrated toolkit can de developed for the creative problem solving in (chemical) process engineering. The combination of the structural modeling with the genetic programming suggests a possible theoretical framework and proposes a practical methodology for the solution of the various synthesis (design, planning, scheduling, …) problems.

An extensible, generic environmental process modelling framework with an example for a watershed of a shallow lake

We present a modelling framework for the generation of environmental process models. The framework builds on the Direct Computer Mapping method with an editable, process network based expert module and interpreter. The expert interface supports mapping of objects from the GIS layers onto the prototyped state, transition and connection elements of the case specific generic process model. The developed general purpose interpreter generates the standardized declarative facts and clauses, describing the actual model with the locally executable program prototypes. This input is executed by the general kernel. The model interpreter generates also the case specific templates for the (optionally web based) user interface, while map-server utilizes the GIS shape files of expert model. The implementation supports the extension of the model with new components in space and time. The framework is illustrated by an example for the watershed of Lake Balaton. Display Omitted We map the GIS objects onto an editable net structure, used as an expert interface.We interpret this net structure to uniform declarative facts and clauses.This declarative simulation model is executed by our general purpose kernel program.The interpretation is accompanied by template generation for the user interface.The environmental model can be extended by new elements and components, easily.

Conservation Based Information System for Agrifood Process Network Interoperability

Based on the stoichiometric structure of conservational processes, a general methodology has been developed for the computer aided generation and operation of network interoperability services. An appropriate set of unified building elements, having autonomous programs and communicating with a dynamic simulating kernel has been elaborated for the qualitative and quantitative tracing and tracking of trans-sectorial processes. The GNU-Prolog implemented method is scalable and makes possible the ad hoc extension of the models with the actually interesting components to be investigated. The system can also be applied for the identification of hidden resources and wastes, as well as for the analysis of the value chains. This outlines a straightforward cooperative architecture of services between the planned interoperability center and the actors, supervised by the responsible authorities. The method will be illustrated by the example of agrifood processes.

Simulation Based Analysis of Nanocarrier Internalization: Exciting Challenges with a New Computational Tool

A new computational tool was developed, for model-based analysis of the endocytosis and exocytosis mechanisms involved in nanocarrier delivery. This was a hypothetical study because current data are insufficient to identify the underlying process model.
