The state process consists of the storage level controlled by the storage manager and the energy price process, which is a diffusion process the drift of which is assumed to be unobservable. We apply filtering theory to find an alternative state process which is adapted to our observation filtration. For this alternative state process, we derive the associated Hamilton-Jacobi-Bellman equation and solve the optimization problem numerically. This results in a candidate for the optimal policy for which it is a priori not clear whether the controlled state process exists. Hence, we prove an existence and uniqueness result for a class of time-inhomogeneous stochastic differential equations with discontinuous drift and singular diffusion coefficient. Finally, we apply our result to prove admissibility of the candidate optimal control.}, language = {en} } @misc{GastingerMeyerShardinetal., author = {Gastinger, Ingo and Meyer, F. and Shardin, Anton and Ptok, Henry and Lippert, Hans and Dralle, Henning}, title = {Untersuchungen zur Hospitalletalit{\"a}t in der Pankreaschirurgie}, series = {Der Chirurg}, volume = {90}, journal = {Der Chirurg}, number = {1}, issn = {1433-0385}, doi = {10.1007/s00104-018-0654-x}, pages = {47 -- 55}, language = {en} } @phdthesis{Shardin, author = {Shardin, Anton}, title = {Stochastische optimale Steuerungsprobleme mit partieller Information f{\"u}r einen Energiespeicher}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:co1-opus4-42490}, pages = {192}, language = {de} }
