• A branch and price approach for deployment of multi-tier software services in clouds 

      Gullhav, Anders Nordby; Nygreen, Bjørn (Journal article; Peer reviewed, 2016)
      This paper considers a service deployment problem that combines service placement and replication level decisions in a cloud computing context. The services are composed of multiple components that are to be placed on nodes ...
    • Adaptive large neighborhood search heuristics for multi-tier service deployment problems in clouds 

      Gullhav, Anders Nordby; Cordeau, Jean-Francois; Hvattum, Lars Magnus; Nygreen, Bjørn (Journal article; Peer reviewed, 2016)
      This paper proposes adaptive large neighborhood search (ALNS) heuristics for two service deployment problems in a cloud computing context. The problems under study consider the deployment problem of a provider of ...
    • Data for a meta-analysis of the adaptive layer in adaptive large neighborhood search 

      Turkeš, Renata; Sörensen, Kenneth; Hvattum, Lars Magnus; Barrena, Eva; Chentli, Hayet; Coelho, Leandro C; Dayarian, Iman; Grimault, Axel; Gullhav, Anders Nordby; Iris, Cagatay; Keskin, Merve; Kiefer, Alexander; Lusby, Richard Martin; Mauri, Geraldo Regis; Monroy-Licht, Marcela; Parragh, Sophie N.; Riquelme-Rodriguez, Juan-Pablo; Santini, Alberto; Santos, Vinicius Gandra Martins; Thomas, Charles (Journal article; Peer reviewed, 2020)
      Meta-analysis, a systematic statistical examination that combines the results of several independent studies, has the potential of obtaining problem- and implementation-independent knowledge and understanding of metaheuristic ...
    • Optimization-based Resource Allocation in Cloud Computing 

      Gullhav, Anders Nordby (Doctoral thesis at NTNU;2016:39, Doctoral thesis, 2016)
      This thesis considers the resource allocation problem of a cloud service provider (SP), which provides at set of services delivered through the software-as-a-service model. The SP owns and operates a private cloud, but in ...
    • Service Deployment in Heterogeneous Cloud-like Environments 

      Gullhav, Anders Nordby (Master thesis, 2011)
      The amount of power consumed by data centres world wide is increasing, and due to growing electricity bills, service providers aim more attention on energy-efficient management of their data centres. In order to achieve ...
    • Simulation of the response time distribution of fault-tolerant multi-tier cloud services 

      Gullhav, Anders Nordby; Nygreen, Bjørn; Heegaard, Poul Einar (Journal article; Peer reviewed, 2016)
      We are considering the problem of obtaining the response time distribution of fault-tolerant multi-tier services. In the provision of software-as-a-service applications, the service provider is obliged to ensure a certain ...
    • Stochastic Master Surgery Scheduling for the orthopaedic department at St. Olav's Hospital 

      Bovim, Thomas Reiten (Master thesis, 2018)
      The regional health authority, Helse Midt-Norge (HMN), provides hospital services to the two counties Trøndelag and Møre og Romsdal. Forecasting estimates that the number of people living in these two counties that exceed ...
