The aim is to foster quantitative methods in the engineering sciences. A role model is the classic Operations Research which has successfully brought discrete mathematics, combinatorial optimization and other formal disciplines to business engineering and management science. Analogously, Technical Operations Research (TOR) focuses now on technical systems and the control and management of their processes. One example is the combination of individual modules into a larger technical systems in the best possible way, when technical constraints as well as economic considerations have to be taken into account. In this way, TOR is meant to bring OR to new areas of applications, which implies the development of new models and algorithmic methods to solve them to optimality. As a side effect, it stimulates the communication between the different areas of expertise, in particular, between engineers, mathematicians, computer scientists and economists. </div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier; min-height: 17px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier; min-height: 17px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier;" class="">Major topics of interests</div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier;" class="">-------------------------</div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier; min-height: 17px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier;" class="">An ideal submission shows a mixture of the three core TOR disciplines:</div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier;" class="">- Problems, models and algorithms: Engineering problems that lead to new TOR research questions, formulated as mathematical optimization problems (e.g., (non-) linear, mixed-integer, ODE/PDE-constrained, robust, stochastic, bilevel, etc.), given rise to the development of new or modified algorithmic approaches for a successful and scalable solution. </div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier;" class="">- Validation and verification: Typically, TOR algorithms use a coarse approximation of physical and technical constraints. Hence their solutions need to be validated and verified by, e.g., simulation models that carry a more refined description of the physics, or by real-world demonstrators and prototypes. This in return shows model-weaknesses and -limits, and can be used to improve formulations and refine models. </div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier;" class="">- Tools for engineers: A major idea of TOR is that the method-oriented disciplines do not replace engineers but extend their capabilities. The goal is to build tools such that the engineers can describe and model a problem at hand, and solve them supported by algorithms. This necessitates the development of tailored modeling languages for describing problem instances as well as interfaces to navigate and explore the solution space in a user-friendly manner.</div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier; min-height: 17px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier; min-height: 17px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier;" class="">Important Dates</div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier;" class="">---------------</div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier; min-height: 17px;" class=""><br class=""></div><div style="margin: 0px; font-stretch: normal; font-size: 14px; line-height: normal; font-family: Courier;" class="">Papers should be submitted online at <a href="https://www.opte-journal.com" class="">https://www.opte-journal.com</a>.
