In-game betting and the Kelly criterion
Andersen, Robin; Hassel, Vegard; Hvattum, Lars Magnus; Stålhane, Magnus (Peer reviewed; Journal article, 2020)When a bet with a positive expected return is available, the Kelly criterion can be used to determine the fraction of wealth to wager so as to maximize the expected logarithmic return on investment. Several variants of the ... -
Layered Formulation for the Robust Vehicle Routing Problem with Time Windows
Agra, Agostinho; Christiansen, Marielle; Figueiredo, Rosa; Hvattum, Lars Magnus; Poss, Michael; Requejo, Cristina (Journal article; Peer reviewed, 2012)This paper studies the vehicle routing problem with time windows where travel times are uncertain and belong to a predetermined polytope. The objective of the problem is to find a set of routes that services all nodes of ... -
Maritime inventory routing : recent trends and future directions
Fagerholt, Kjetil; Hvattum, Lars Magnus; Papageorgiou, Dimitri J.; Urrutia, Sebastián (Peer reviewed; Journal article, 2023)We review recent literature pertaining to the maritime inventory routing problem (MIRP), a stimulating, albeit niche, subclass of vendor-managed inventory problems. MIRPs deal with optimally distributing products with a ... -
A MIP based local search heuristic for a stochastic maritime inventory routing problem
Agra, Agostinho; Christiansen, Marielle; Hvattum, Lars Magnus; Rodrigues, Filipe (Chapter, 2016)We consider a single product maritime inventory routing problem in which the production and consumption rates are constant over the planning horizon. The problem involves a heterogeneous fleet of ships and multiple production ... -
Modelling clubs' financial investment in association football players
Sæbø, Olav Drivenes (Master thesis, 2015)Previous attempts at modelling players' value to association football clubs have to a large extent been occupied with average market behaviour, while specific clubs' situations have been afforded less attention. In this ... -
Modelling Off-Ball Decision Making in Swedish Top Division Football
Cook, Tristan Kristoffer; Keil, Eivind; Sætherø, Inge Dovre (Master thesis, 2020)Den publiserte analytiske forskningen innen fotball er voksende, men fortsatt finnes flere interessante aspekter ved idretten som ikke er belyst gjennom akademisk forskning. Denne masteroppgaven søker å supplementere ... -
Modelling the financial contribution of soccer players to their clubs
Sæbø, Olav Drivenes; Hvattum, Lars Magnus (Journal article; Peer reviewed, 2018)This paper presents a framework for evaluating the financial consequences of player transfers as seen from a club’s perspective. To this end, an objective player rating model is designed based on players’ contribution towards ... -
New benchmark instances for the inventory routing problem
Skålnes, Jørgen; Ben Ahmed, Mohamed; Hvattum, Lars Magnus; Stålhane, Magnus (Journal article; Peer reviewed, 2023)The existing sets of benchmark instances for the inventory routing problem (IRP) have been beneficial for investigating and illustrating the properties of the problem. However, they possess certain features and design ... -
Operating Room Scheduling Problem: Considering the uncertain arrivals of the emergency patients and the capacity limits of the pre-op and post-op facilities
Agdestein, Sofie Døving (Master thesis, 2012)This thesis proposes a solution approach to the operating room scheduling problem (ORSP) with two types of demand for surgery: known elective demand and uncertain emergency demand. The ORSP consists of scheduling elective ... -
Optimal lagerstyring av kontanter i minibanker med usikker etterspørsel
Bakken, Geir Martin; Wiik, Michael (Master thesis, 2014)Lønnsomheten av norske bankers drift av minibanker er redusert de siste årene. Dette som en konsekvens av blant annet en kraftig økning av korttransaksjoner og dertil nedgang i kontantuttak fra minibanker. Redusert lønnsomhet ... -
