Abstract: Provided is a method to determine a production plan including steps to identify production means, to identify at least one product for each production means, which can be manufactured with the aid of the production means; to identify at least one raw material required for its production for each product; to identify which of the products is used as a raw material for which other product; to model the identified circumstances as MIP; and to determine a solution to the MIP. Thereby, the solution is optimized to the furthest extent possible with regard to at least one predetermined parameter and indicates which product at which time should be manufactured with the aid of which production means and based on which raw material.

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.
