Systeemianalyysin laboratorion 40-vuotisseminaari

Julkaisupäivämäärä: 23.12.2024

Systeemianalyysin laboratorio perustettiin vuonna 1984. Sittemmin laboratoriosta on valmistunut 85 tekniikan tohtoria ja yli 640 diplomi-insinööriä. Tämä seminaari puntaroi systeemi- ja operaatiotutkimuksen merkitystä koulutuksen, tutkimuksen ja yhteiskunnallisen vaikuttamisen näkökulmista. Samoin se jäsentää niitä osaamistarpeita ja tutkimuksellisia edistysaskeleita, joita tarvitaan luovittaessa tulevaisuuteen epävarmuuksien keskellä. Ohjelma ilmoittautumislinkkeineen (määräaika 6.1.) on osoitteessa

A Public Lecture by Prof. Giovanni Pantuso

Julkaisupäivämäärä: 28.08.2024
In this talk, I present an exact solution method for two-stage stochastic programs under decision-dependent uncertainty. In such problems, first-stage decisions determine the probability distribution of second-stage uncertain parameters.  Particularly, we focus on a broad class of problems where the number of potential probability distributions is finite but exponentially large. In these problems, the recourse function is non-convex and discontinuous even for problems with continuous second-stage. The proposed method extends the well-known L-Shaped method and is applicable also to two-stage stochastic programs with integer variables at both stages. We show that the algorithm converges finitely and propose a number additional improvements that facilitate convergence, such as valid inequalities. Results of numerical experiments on a facility location problems under endogenous uncertainty show promising scalability and efficiency also on very challenging problems.
