Abstract: A method determines a cabling of a unit of a photovoltaic system. The unit includes a number of solar components and a transfer point. The method includes generating a cabling chart with paths between a connection of each solar component and the transfer point according to cable routing regulations, determining preferred paths of each solar component to the transfer point based on the cabling charts, and selecting one of the determined paths for each solar component such that the cabling complexity for the unit is minimized. In the process, the cabling complexity is determined based on the sum of the lengths of the selected paths and the length of a cable channel in which the cables run individually or in a bundled manner.

Abstract: A method for generating code in a predefined programming language based on an optimization problem is provided. The method includes reading a model of the optimization problem, and identifying references to external data sources in the model. The external data sources are external to the model. The method also includes generating the code. The code includes a program representation of the model. The code includes read and/or write accesses to the external data sources. A corresponding code generator and a software development environment are also provided.

Abstract: A system, method, and an associated computer program (product) for optimizing an arrangement of objects formed from at least one structure in order to use objects to design a technical installation is provided. The system has: a selection device for selecting objects that are filtered from a set of provided objects on the basis of properties of the objects and/or arrangement conditions derived from the relationships of the objects among one another and/or by means of prescribable parameters, a processing device designed to make an association between each selected object and at least one subarea of the technical installation, an optimization device designed to perform optimization of the arrangement of the selected objects within their subarea, if need be iteratively, by rotating and/or by tilting and/or sorting and/or rearranging the objects, an output device for outputting the optimized arrangement of the objects to use this arrangement for designing the installation.
