Embodiment Construction

[0039] Different aspects have to be considered when optimizing the production process of a production plant in a production company. On the one hand, energy must be obtained in order to operate production plants. This occurs, for example, by: by purchasing energy at an energy supplier; by generating energy internally, for example through solar cells, wind turbines and / or small power plants owned by a household or business; Forms the reuse of energy, especially to obtain electrical energy from accumulated thermal energy.

[0040]On the other hand, production plants consume energy, wherein the individual production processes each have their own energy consumption. During times of high energy availability, production can thus be increased and produced for storage as much as possible in excess of actual demand, while production is limited or even excess energy, especially electricity, can be fed back into the grid during periods of low energy availability. However, the optimal u...

Abstract

A method and an apparatus are disclosed for operating a production plant in a production process in the manufacturing industry or the process industry by optimizing the operation of the production process, in which the efficient use of the available energy is taken into account as a further optimization variable.

Description

technical field [0001] The present invention generally relates to methods for optimizing production processes in the manufacturing or process industries. The invention also relates to measures for the energy-efficient operation of production plants, ie to plan, regulate and control production in such a way that energy requirements and raw material requirements are respectively optimized. Background technique [0002] In previous methods for production planning and production execution, an attempt was made to optimize production with respect to one or more process variables. This takes place taking into account various boundary conditions, such as order deadlines, machine constraints, maintenance downtimes and the like. For this optimization, mathematical optimization methods are used in many cases, which lead to an optimal solution for a predefined cost function and boundary conditions, where the cost function "cost function" or the objective function "objective function" o...
