Testing of Direct Computer Mapping for dynamic simulation of a simplified Recirculating Aquaculture System

Abstract

A B S T R A C TFirst implementation and testing of Direct Computer Mapping (DCM) based methodology for modeling and dynamic simulation of Recirculating Aquaculture Systems (RAS) were made and evaluated. The test model of the underlying hybrid, multiscale processes were generated for a simplified example system, utilizing data and empirical equations for the production of African catfish (Clarias gariepinus) from the available literature. The Waste Water Treatment model was temporarily implemented by efficiency factor. The authors studied how the graphically generated, locally programmable building elements can be applied for dynamic simulation of the given complex system. According to these previous test results, DCM methodology can give a flexible and robust solution to describe the backbone structure of a core model that can be adapted to the changing formulation and data in the local models, individually. In addition, DCM methodology seems to be able to generate the various RAS schemes from the model of a single fish tank. Based on the experiences, as well as, with the knowledge of a more comprehensive data and relationships, in the ongoing work we shall implement and analyze complex RAS models.

Dynamic simulation based method for the reduction of complexity in design and control of Recirculating Aquaculture Systems

“…In our previous work, we implemented and tested an example RAS model by the Direct Computer Mapping based modeling and simulation methodology [22]. Based on these previous results we tried to develop a model based complexity reducing method for the design and control of RAS.…”
