Seminar will give a deeper insight into the general modeling and simulation method of Programmable Process Structures (PPS).
PPS offers automatic generation of easily extensible and connectable, dynamic balance-based models for the analysis, design, planning, operation and control of complex process systems. The resulting models consist of unified state and transition elements, transition oriented structure representation and locally programmable prototypes. PPS models can be generated from two general meta-prototypes and from the corresponding description of the process structure. The local program containing prototype elements, executing the case-specific calculations, are also derived from the same meta-prototypes, prepared to distinguish between the model-specific conservation-laws-based measures and the other measures and information (called signals). Simulation is executed according to the connections amongst the actual state and transition elements, accompanied by the data transfer between the actual elements and their calculating prototypes. This architecture and its AI language-based implementation support the integration of various field- and task-specific models, conveniently.
Application of PPS will be illustrated through different cases, focusing also on agricultural and environmental applications, as well as on prospective new fields of circular processes.
Monika Varga senior researcher, Bolyai Scholar of the Hungarian Academy of Sciences. She works at the Hungarian University of Agriculture and Life Sciences, Hungary. As an agricultural engineer (majoring in agricultural informatics), she has been participating in the work of Research Group on Process Network Engineering (under re-organization) from 2006. Her research focuses on the further development and implementation of a non-conventional method (PPS), for the modeling and simulation based analysis, design and control of a wide range of process systems. Areas of application cover various fields from cellular biological processes to complex agro-environmental systems. Some recent works focused on the process model based analysis, planning and operation of intensive Recirculating Aquaculture Systems, semi-intensive fishponds and agroforestry systems. She participated in the professional elaboration of 15 contract based Hungarian industrial works, 8 domestic research projects, 5 international cooperation projects (in 2 cases as PI) and the professional preparation of 5 Horizon2020 projects. In 2019, she spent a semester at Ohio State University (Columbus, OH, US) as a Fulbright researcher, working on the development of interfacing models between detailed dynamic simulation and higher level evaluations in context of Circular Economy.
