Decision Trees as a connector between scientific research and practitioners uses cutting edge methodologies of Stochastic Optimization and offers customized software and consultancy to energy producers and traders. Decision Trees helps utilities to understand new mathematical concepts of decision making under uncertainty. We tailor our products together with utilities' staff and introduce new stochastic valuation and optimization methods into day to day operations. Decision Trees implements complex mathematics of Stochastic Optimization in usable, highly performing software. Decision Trees' consultants explain mathematics understandably and introduce it into clients' business processes as transparently as possible. Decision Trees aims to address client’s current and future needs with revolutionary yet dependable combination of mathematics and technology that exceeds the performance and potential of legacy deterministic optimization applications. The company started operations in St. Gallen 2005 and currently conducts its so far largest project with Trianel European Energy Trading GmbH, Europe's most successful energy trading firm in the municipal utility sector. The founders' central belief is that more advanced mathematical optimization technologies, including parallel Cplex as solver, yields far better business decisions that are well hedged against unfavorable future evolutions and at the same time take profit opportunities in case of beneficial future evolutions. Decision making has become far too rigid and complex for people to use experience based approaches or simple deterministic models. Decision Trees provides stochastic optimization models that take into account future uncertainty. They are used far more productively compared to conventional approaches and fit new needs arising over time.
