  2. 1. Two-Barrier Problems in Applied Probability: Algorithms and Analysis

    Author : Mats Pihlsgård; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; operations research; programming; actuarial mathematics; Statistik; Matematik; Mathematics; Naturvetenskap; Natural science; Reflection; Stochastic processes; Applied probability; Queueing; operationsanalys; programmering; aktuariematematik;

    Abstract : This thesis consists of five papers (A-E). In Paper A, we study transient properties of the queue length process in various queueing settings. We focus on computing the mean and the Laplace transform of the time required for the queue length starting at $x0. We define the loss rate due to the reflection. READ MORE

  4. 2. On Perfect Simulation of Markovian Queueing Networks with Blocking

    Author : Dan Mattsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Markov chain; Monte Carlo methods; Propp-Wilson algorithm; perfect simulation; queueing theory; Jackson networks; birth and death processes; Jackson networks;

    Abstract : Perfect simulation of a class of Markovian queueing networks with finite buffers is examined in this monograph. The network processes defined are modelled by restricted multivariate birth and death processes with intensities depending on a random environment. The random environments are mainly a set of independent onoff processes. READ MORE

  5. 3. Marginal Productivity Indices and Linear Programming Relaxations for Dynamic Resource Allocation in Queueing Systems

    Author : Jianhua Cao; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Markov decision process; Indexability; Linear programming; Queueing theory; Optimization;

    Abstract : Many problems concerning resource management in modern communication systems can be simplified to queueing models under Markovian assumptions. The computation of the optimal policy is however often hindered by the curse of dimensionality especially for models that support multiple traffic or job classes. READ MORE

  6. 4. Dynamical Modeling of Cloud Applications for Runtime Performance Management

    Author : Johan Ruuskanen; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud computing; Performance modeling; Queueing theory; Processor sharing; Mean-field approximation; Fluid model; Microservices; Load balancing; Request cloning;

    Abstract : Cloud computing has quickly grown to become an essential component in many modern-day software applications. It allows consumers, such as a provider of some web service, to quickly and on demand obtain the necessary computational resources to run their applications. READ MORE

  7. 5. Analysis of Lateral Transshipments in Inventory Systems

    Author : Stefan Vidgren; Produktionsekonomi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Queueing theory; Inventory control; Stochastic; Lateral transshipments; Optimization;

    Abstract : This thesis is based on two scientific papers. In these papers we study how one can approximate the inventory level of probabilities and the transshipment rates for inventory systems that apply lateral transshipment policies. READ MORE
