The federal law on working time, working time models, collective agreements and company agreements were analyzed. The various working time models applied in the German economy were examined, analyzed and classified. As a result, dependencies, groupings and correlations were identified and mapped in a data model. Furthermore, a questionnaire was developed for employees and employers to assess the acceptance of the criteria. The classification of the working time models resulted in two basic categories: (1) Time: a distinction is made between reduced and full working hours and (2) Flexibility: working hours can be variable or fixed.     <\/p><p><strong>In the second area of work <\/strong>, the concept and formal description of multi-objective optimization methods were developed. To analyze the optimization algorithms, mathematical optimization problems were examined for their suitability. From this, a number of related problems and associated solution methods were identified and delineated. In order to rationalize the development and modelling activities, a graphical platform for testing various calculation methods was implemented. After the concept was created, a prototype for shift distribution for employee planning was developed with MathLab.    <\/p><p><strong>The third part<\/strong> consisted of the formal description, development and creation of the optimizer. The software consists of three main modules: a database with known working time models, a \u201cshift planning\u201d module (a simulator that suggests the most favorable number and time distribution of shifts based on entered operating parameters) and the \u201cproduction planning\u201d module (a tool that calculates a production plan for execution based on production sequences, number of machines and given orders).   <\/p><p>The various modules will be applied in the further course of the project and tested and validated in simulations in consultation with industry partners. The partners provide practical and realistic data for energy and working time organization in order to be able to carry out realistic simulations in the further course of the project.
