2. 1. Inventory control and scheduling problems in a single-machine multi-item system

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

   Abstract : This Doctoral Thesis addresses the topic of inventory control and scheduling in a single-machine multi-item system. Specifically, it considers a group of items processed, one at a time, on a single facility. Single-machine multi-item systems occur frequently in practice and apply both in continuous flow processes and batch flow processes. READ MORE

4. 2. On Rank-invariant Methods for Ordinal Data

   Author : Yishen Yang; Sune Karlsson; Elisabeth Svensson; Rolf Larsson; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ordinal data; rank-invariance; systematic change; agreement; association; inter-rater reliability; ranking; Spearman; multi-item scale; Statistik; Statistics;

   Abstract : Data from rating scale assessments have rank-invariant properties only, which means that the data represent an ordering, but lack of standardized magnitude, inter-categorical distances, and linearity. Even though the judgments often are coded by natural numbers they are not really metric. READ MORE

   Author : Olle Hägg; Göteborgs universitet; []
   Keywords : Chronic low back pain; clinical outcome; global assessment; measurement; ; minimal clinically important difference; pain drawing; physical disability; predictors.;

   Abstract : Background: Outcome of surgery for chronic low back pain should be documented ina standardised and reproducible fashion to establish evidence of its benefit. Measurement of outcome requires validated instruments, which have the ability to detect functionalchanges perceived as beneficial by the patient. READ MORE
