  1. 1. Data quality in marine biotoxins’ risk assessment: Perceptions from data production to consumption

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Panagiota Katikou; [2022]
    Keywords : Data quality; Data quality dimensions; Data production; Data collection; Data consumption; Data roles; Marine Biotoxins; Risk assessment;

    Abstract : Marine biotoxins constitute one of the major hazards associated with seafood consumption. Risk assessments are essential for the effective management of problems arising from marine biotoxins occurrence, as they are a prerequisite for the establishment or periodic re-evaluation of marine biotoxins regulatory limits and for the adoption of appropriate risk management plans.

  3. 2. Periodical Maintenance Modelling and Optimisation Assuming Imperfect Preventive Maintenance and Perfect Corrective Maintenance

    University essay from KTH/Optimeringslära och systemteori

    Author : Madeleine Engvall Birr; Lisette Lansryd; [2021]
    Keywords : Master Thesis; Maintenance Management; Maintenance Modelling; Imperfect PM; Perfect CM; Periodic Policy; Genetic Algorithms; Age Reduction; Masterexamensarbete; Underhållsarbete; Underhållsmodellering; Ofullständiga FU; Perfekta AU; Periodisk Planläggning; Genetiska Algoritmer; Åldersreduktion;

    Abstract : In this paper, a periodic maintenance model is formulated assumingcontinuous monitoring, imperfect preventive maintenance (PM) and perfect correctivemaintenance (CM) using three decision variables, (I, N, Z). The model is derived in aninfinite horizon context where the mean cost per unit time is modelled. READ MORE

  4. 3. Seasonal Adjustment of Weekly Trade Data

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Hannes Jägerstedt; [2021]
    Keywords : Seasonal adjustment; Weekly observations; Splines; Kalman Filter; International Trade;

    Abstract : The main objective of this paper is to equip the trade policy analyst with an appropriate method of seasonally adjusting trade data with weekly observations. To that end, a structural time series model containing a trend, seasonal and irregular component is specified. The seasonal component is represented by a time-varying periodic spline. READ MORE

  5. 4. Implementation of an Age of Information-aware Scheduler for Resource Constrained Devices

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Lukas Wirne; [2019]
    Keywords : ;

    Abstract : We examine a system where remote applications frequently request fresh information from sensor nodes through an edge and cloud based infrastructure. We study a scheduling policy that ensures fresh information while reducing energy consumption. In this work we build a testbed for evaluating the performance of the policy. READ MORE

  6. 5. Forming an Inventory Control Policy in a Stochastic Environment: A Case Study at Sandvik Crushing and Screening

    University essay from Lunds universitet/Produktionsekonomi

    Author : Anders Mattisson; David Alsmarker; [2018]
    Keywords : Inventory Control; Stochastic Lead Time; Stochastic Demand; Input Analysis; Optimization; Technology and Engineering;

    Abstract : Background: For most companies that handle large material flows there are buffers between different stages in the supply chain, often referred to as inventory. The main reasons for having these inventories are to achieve economies of scale when handling material flows and to buffer against uncertainties when matching demand and supply. READ MORE
