  1. 1. Wind Turbine Recovery Forecasting using Survival Analysis

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Anton Palets; [2023]
    Nyckelord :Survival analysis; Recovery Forecast; Wind Turbine; Availability Forecast; AFT model; Aalen s model; Cox regression; Cox Proportional Hazards; Variation Processes; Mathematics and Statistics;

    Sammanfattning : The goal of this thesis is to present a methodology for predicting time until recovery of failed wind turbines. The necessity is motivated by the potential for more accurate wind energy export forecasts. The current approach rests entirely on having an expert examine the turbine and produce a time estimate.

  2. 2. Predictive Regression Model Evaluation : Evaluating Predictive Machine Learning Models to Reduce Food Waste in the Dairy Industry

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Alexander Carlsson; [2023]
    Nyckelord :Machine learning; Food loss; Food overproduction; Food waste forecast; Food waste prediction; Maskininlärning; Matsvinn; Svinn; Matsvinnsprognos;

    Sammanfattning : Food waste in the food industry is often a result from the complex nature of food production. Uncertainty is always present as yields vary and as there is a chain of consumer demand from stores to producers. Food waste is a waste of both natural and economic resources affecting both the planet and the producer. LÄS MER

  3. 3. Flexibility of electricity usage in private households with smart control : Modelling of a smart control system with the aim to reduce the electricity cost of private households with storage units and photovoltaic systems.

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Marina Pakola; Antonia Arab; [2022]
    Nyckelord :Smart control of electricity usage; optimization; mixed-integer linear programming MILP ; electricity price forecasting; load forecasting; storage systems in private households; electricity costs in Sweden;

    Sammanfattning : High electricity prices have become the title of several news articles recently in Sweden and the prices have experienced large sudden fluctuations during certain periods. In this thesis work, a smart control model for the electricity usage in three different households has been developed with the main purpose to minimize the electricity cost. LÄS MER

  4. 4. Forecasting food waste: The case of a Swedish grocery company - A quantitative & exploratory study of how to forecast food waste for a Swedish retailer

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för marknadsföring och strategi

    Författare :Joel Ridderstråle; William Lundström; [2020]
    Nyckelord :Foodwaste; Forecast; Retail; Retail Forecasting; Regression;

    Sammanfattning : In the retail stage of a food supply chain, the occurrence of food waste is often caused by inaccurate forecasting of sales, which leads to incorrect ordering of products. Previous literature has suggested using more accurate demand forecasts on the sales data in order to combat the problem. LÄS MER

  5. 5. Election Forecasting in a Multiparty System

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Stefan Lindborg; [2019-01-31]
    Nyckelord :Election forecasting; Polling; Multiparty systems; Dynamic Linear Models; DLM; Kalman filtering; Swedish elections;

    Sammanfattning : This bachelor thesis in statistics covers the subject of election forecasting in a multiparty system, using polling data, that is data collected to measure party support, and dynamic linear models (DLMs) with Kalman filtering. In terms of decision-making the outcome of an election can be thought of as an uncertainty. LÄS MER
