Determining Patient-Specific Dosage Scheme Using Integer Programming
Finding the correct substitution dosage of levothyroxine after total thyroidectomy can be time consuming using current methods. We present a mixed integer quadratic programming model for determining correct dosage given characteristics of a patient. The model is flexible in terms of determining fixe...

Managing Uncertainty in Design and Operation of Natural Gas Infrastructure
Assessing Production Assurance in a Natural Gas Network by Using Scenario Generation and Optimization
We discuss how an optimization model can be used together with a scenario generation procedure to provide valuable analysis for companies operating in a natural gas value chain. The solution time of the optimization model can be considerable for some model specifications, so a large scale sampling f...
Optimization model to analyse optimal development of natural gas fields and infrastructure
We present an optimization model for analysis of system development for natural gas fields, processing and transport infrastructure. In this paper we present our experience from performing analyses for the natural gas industry with the optimization model. We also present a model extension in the for...
Multi-horizon stochastic programming
Infrastructure-planning models are challenging because of their combination of different time scales: while planning and building the infrastructure involves strategic decisions with time horizons of many years, one needs an operational time scale to get a proper picture of the infrastructure’s perf...
Kvantitativ driftsevaluering av akuttstuene ved St. Olavs Hospital - Forslag til tiltak for å redusere ventetider
Hensikten med dette arbeidet har vært å analysere pasientflyt, ventetider, kapasitets- og ressursutnytelse i forhold til behandling av pasienter ved Akuttsenteret. Arbeidet er basert på empiriske registreringer de siste halvannet år i kombinasjon med en simuleringsmodell som er u...
