1. 16. Evaluation of forecasting techniques and forecast errors : with focus on intermittent demand

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

   Sammanfattning : 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. LÄS MER

3. 17. Essays on capacity, forecasting and lot scheduling

   Författare :Erik Levén; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

   Sammanfattning : Production-inventory systems are concerned with the effective management of the total flow of goods, from the acquisition of raw materials to the delivery of finished products to the final customer. A production-inventory system is composed of a large number of elements which have to be managed effectively in order to deliver the final products in appropriate quantities, to where they are required, at the desired time and quality, and at a reasonable cost.

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary-layer meteorology; WRF; Initialization; Stratocumulus clouds; Parameterization; Stable boundary layer; Single Column Model; meteorologi; Meteorology;

   Sammanfattning : The Swedish Armed Forces setup of the Weather Research and Forecasting Model (WRF) has problems to forecast low clouds in stably stratified conditions when the ground is covered by snow. The aim of this thesis is to understand what causes this deficit. LÄS MER

5. 19. Modelling and forecasting economic time series with single hidden-layer feedforward autoregressive artificial neural networks

   Författare :Gianluigi Rech; Handelshögskolan i Stockholm; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This dissertation consists of 3 essays In the first essay, A Simple Variable Selection Technique for Nonlinear Models, written in cooperation with Timo Teräsvirta and Rolf Tschernig, I propose a variable selection method based on a polynomial expansion of the unknown regression function and an appropriate model selection criterion. The hypothesis of linearity is tested by a Lagrange multiplier test based on this polynomial expansion. LÄS MER
