    <title language="eng">Using white-box nonlinear optimization methods in system dynamics policy improvement</title>
    <abstract language="eng">We present a new strategy for the direct optimization of the values of policy functions. This approach is particularly well suited to model actors with a global perspective on the system and relies heavily on modern mathematical white-box optimization methods. We demonstrate our strategy on two classical models: market growth and World2. Each model is first transformed into an optimization problem by defining how the actor can influence the models' dynamics and by choosing objective functions to measure improvements. To improve comparability between different runs, we also introduce a comparison measure for possible interventions. We solve the optimization problems, discuss the resulting policies and compare them to the existing results from the literature. In particular, we present a run of the World2 model which significantly improves the published “towards a global equilibrium” run with equal cost of intervention.</abstract>

    <title language="eng">Validation of Nominations in Gas Network Optimization: Models, Methods, and Solutions</title>
    <abstract language="eng">In this article we investigate methods to solve a fundamental task in gas transportation, namely the validation of nomination problem: Given a gas transmission network consisting of passive pipelines and active, controllable elements and given an amount of gas at every entry and exit point of the network, find operational settings for all active elements such that there exists a network state meeting all physical, technical, and legal constraints.&#13;
&#13;
We describe a two-stage approach to solve the resulting complex and numerically difficult feasibility problem. The first phase consists of four distinct algorithms applying linear, and methods for complementarity constraints to compute possible settings for the discrete decisions. The second phase employs a precise continuous programming model of the gas network. Using this setup, we are able to compute high quality solutions to real-world industrial instances that are significantly larger than networks that have appeared in the mathematical programming literature before.</abstract>

    <title language="eng">Mathematical optimization for challenging network planning problems in unbundled liberalized gas markets</title>
    <abstract language="eng">The recently imposed new gas market liberalization rules in Germany lead to a change of business of gas network operators. While previously network operator and gas vendor were united, they were forced to split up into independent companies. The network has to be open to any other gas trader at the same conditions, and free network capacities have to be identified and publicly offered in a non-discriminatory way. We discuss how these changing paradigms lead to new and challenging mathematical optimization problems. This includes the validation of nominations, that asks for the decision if the network’s capacity is sufficient to transport a specific amount of flow, the verification of booked capacities and the detection of available freely allocable capacities, and the topological extension of the network with new pipelines or compressors in order to increase its capacity. In order to solve each of these problems and to provide meaningful results for the practice, a mixture of different mathematical aspects have to be addressed, such as combinatorics, stochasticity, uncertainty, and nonlinearity. Currently, no numerical solver is available that can deal with such blended problems out-of-the-box. The main goal of our research is to develop such a solver, that moreover is able to solve instances of realistic size. In this article, we describe the main ingredients of our prototypical software implementations.</abstract>

    <title language="eng">Valid inequalities for the topology optimization problem in gas network design</title>
    <abstract language="eng">One quarter of Europe's energy demand is provided by natural gas distributed through a vast pipeline network covering the whole of Europe. At a cost of 1 million Euro per km extending the European pipeline network is already a multi-billion Euro business. Therefore, automatic planning tools that support the decision process are desired. Unfortunately, current mathematical methods are not capable of solving the arising network design problems due to their size and complexity. In this article, we will show how to apply optimization methods that can converge to a proven global optimal solution. By introducing a new class of valid inequalities that improve the relaxation of our mixed-integer nonlinear programming model, we are able to speed up the necessary computations substantially.</abstract>

    <title language="eng">The Freight Train Routing Problem for Congested Railway Networks with Mixed Traffic</title>
    <abstract language="eng">We consider the following freight train routing problem (FTRP).&#13;
Given is a transportation network with fixed routes for passenger&#13;
trains and a set of freight trains (requests), each defined by an&#13;
origin and destination station pair. The objective is to&#13;
calculate a feasible route for each freight train such that the&#13;
sum of all expected delays and all running times is minimal.&#13;
Previous research concentrated on microscopic train routings for&#13;
junctions or inside major stations. Only recently approaches were&#13;
developed to tackle larger corridors or even networks. We&#13;
investigate the routing problem from a strategic perspective,&#13;
calculating the routes in a macroscopic transportation network of&#13;
Deutsche Bahn AG. In this context, macroscopic refers to an&#13;
aggregation of complex and large real-world structures into fewer&#13;
network elements. Moreover, the departure and arrival times of&#13;
freight trains are approximated. The problem has a strategic&#13;
character since it asks only for a coarse routing through the&#13;
network without the precise timings. We provide a mixed-integer&#13;
nonlinear programming (MINLP) formulation for the FTRP, which is&#13;
a multicommodity flow model on a time-expanded graph with&#13;
additional routing constraints. The model’s nonlinearities&#13;
originate from an algebraic approximation of the delays of the&#13;
trains on the arcs of the network by capacity restraint&#13;
functions. The MINLP is reduced to a mixed-integer linear&#13;
model (MILP) by piecewise linear approximation. The latter is&#13;
solved by a state-of-the art MILP solver for various real-world&#13;
test instances.</abstract>

    <title language="eng">Convex reformulations for solving a nonlinear network design problem</title>
    <abstract language="eng">We consider a nonlinear nonconvex network design problem that arises, for example, in natural gas or water transmission networks. Given is such a network with active and passive components, that is, valves, compressors, control valves (active) and pipelines (passive), and a desired amount of flow at certain specified entry and exit nodes in the network. The active elements are associated with costs when used. Besides flow conservation constraints in the nodes, the flow must fulfill nonlinear nonconvex pressure loss constraints on the arcs subject to potential values (i.e., pressure levels) in both end nodes of each arc. The problem is to compute a cost minimal setting of the active components and numerical values for the flow and node potentials. We examine different (convex) relaxations for a subproblem of the design problem and benefit from them within a branch-and-bound approach. We compare different approaches based on nonlinear optimization numerically on a set of test instances.</abstract>

    <title language="eng">A primal heuristic for optimizing the topology of gas networks based on dual information</title>
    <abstract language="eng">We present a novel heuristic to identify feasible solutions of a mixed-integer nonlinear programming problem arising in natural gas transportation: the selection of new pipelines to enhance the network's capacity to a desired level in a cost-efficient way. We solve this problem in a linear programming based branch-and-cut approach, where we deal with the nonlinearities by linear outer approximation and spatial branching. At certain nodes of the branching tree, we compute a KKT point of a nonlinear relaxation. Based on the information from the KKT point we alter some of the binary variables in a locally promising way exploiting our problem-specific structure. On a test set of real-world instances, we are able to increase the chance of identifying feasible solutions by some order of magnitude compared to standard MINLP heuristics that are already built in the general-purpose MINLP solver SCIP.</abstract>
