We present a control problem for an electrical vehicle. Its motor can be operated in two discrete modes, leading either to acceleration and energy consumption, or to a recharging of the battery. Mathematically, this leads to a mixed-integer optimal control problem (MIOCP) with a discrete...

We are interested in the optimal control of sewage networks. It is of high public interest to minimize the overflow of sewage onto the streets and to the natural environment that may occur during periods of heavy rain. The assumption of linear flow in a discrete time setting has proven to be...

We are interested in structures and efficient methods for mixed-integer nonlinear programs (MINLP) that arise from a first discretize, then optimize approach to time-dependent mixed-integer optimal control problems (MIOCPs). In this study we focus on combinatorial constraints, in particular on...

We consider integer-restricted optimal control of systems governed by abstract semilinear evolution equations. This includes the problem of optimal control design for certain distributed parameter systems endowed with multiple actuators, where the task is to minimize costs associated with the...

This paper quantifies the macroeconomic impacts of the Kyoto Protocol's Clean Development Mechanism (CDM) employing a computable general equilibrium model of international trade and energy use. We incorporate project-based CDM supply data in order to assess the relative importance of transaction...

In view of the controversial policy debate on “green” growth and corresponding stimulus packages we empirically investigate the production effects of environmental investment as well as of environmental and energy expenditures. Using a panel dataset of German manufacturing sectors our...
