  2. 1. Enhancing aftermarket demand planning with product-in-use data

    Author : Joakim Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Big data; Digitalization; Product-in-use.; Forecasting; Demand planning; Aftermarket;

    Abstract : Enhancing aftermarket demand planning with product-in-use data ABSTRACT Aftermarket demand planning, consisting of forecast and known demand, is a critical activity for both the uptime of customers’ products and the supply chain-related costs. Traditional aftermarket forecasting methods use historical demand as the only input to the statistically based forecasts, usually combined with judgmental modifications. READ MORE

  4. 2. Hydrological Seasonal Forecasting

    Author : Kean Foster; Avdelningen för Teknisk vattenresurslära; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrological seasonal forecasting; seasonal forecast; spring flood; multi-model ensembles; teleconnection patterns; modelling chain;

    Abstract : In Sweden, almost half of the electricity produced comes from hydropower. However, the amount of water in the reservoir catchments is not evenly distributed throughout the year. During the colder months, precipitation usually falls as snow and accumulates into a snowpack. READ MORE

  5. 3. Count data modelling and tourism demand

    Author : Jörgen Hellström; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Time series; Count data; INARMA; Unit root; Aggregation; Forecasting; Tourism; Truncation; Inflation; Simulated maximum likelihood; Bivariate hurdle model.;

    Abstract : This thesis consists of four papers concerning modelling of count data and tourism demand. For three of the papers the focus is on the integer-valued autoregressive moving average model class (INARMA), and especially on the ENAR(l) model. READ MORE

  6. 4. Evaluation of forecasting techniques and forecast errors : with focus on intermittent demand

    Author : Peter Wallström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

    Abstract : To decide in advance the amount of resources that is required next week or next month can be both a complicated and hazardous task depending on the situation, despite the known time frame when the resources are needed. Intermittent demand, or slow-moving demand, that is when there are time periods without demand and then suddenly a time period with demand, becomes even more difficult to forecast. READ MORE

  7. 5. Characterization and forecasting of wind conditions over the Baltic Sea

    Author : Christoffer Hallgren; Erik Sahlée; Julie Lundquist; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; forecasting; low-level jet; lidar; machine learning; mesoscale meteorology; numerical weather prediction; post-processing; reanalysis; sea breeze; turbulence; wind atlas; wind energy; wind power; Meteorologi; Meteorology;

    Abstract : To meet the increasing demand of sustainably produced electricity, the total number of installed wind turbines is rapidly increasing globally. Although onshore installations are dominating, offshore wind power is taking a greater share of the market every year. READ MORE
