1. 1. Disruption Analysis - An Important Tool in Lean Production

   Författare :Johan Ericsson; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production technology; TPM.; Kaizen; JIT; Lean Production; Manufacturing system; Disruption; Downtime; Produktionsteknik;

   Sammanfattning : This thesis is divided in two parts which are strongly connected. Part one deal with disruptions occurring in connection with machine down-time, quality losses and increased cycle time. The analysis is based on 10 studies, in which down-time losses in Swedish industry have been registered. LÄS MER

3. 2. Reliability and Life Cycle Cost Modelling of Mining Drilling Rigs

   Författare :Hussan Hamodi; Jan-Gunnar Persson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Sammanfattning : In the context of mining, drilling is the process of making holes in the face and walls of underground mine rooms, to prepare those rooms for the subsequent operation, which is the charging process. Due to the nature of the task, drilling incurs a high number of drilling rig failures. LÄS MER

4. 3. Methods for availability improvements of a scaling machine system

   Författare :Andi Rahadiyan Wijaya; Jan-Gunnar Persson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Sammanfattning : Scaling is the process of cleaning loose material from the roof, face and wall of the mine room in underground mining. The purpose of scaling is to make the mine room safe for the next operation. Due to the nature of the task, scaling has been identified as an operation with a high number of accident occurrences.

5. 4. Production Costs Calculation Model in Crushing and Screening : Using a technical-economic approach tool for finding the optimal production costs when comparing technical and economical solutions

   Författare :Per Hedvall; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Krossning; siktning; sortering; krossanläggningar; processer; produkter; kostnad; entreprenadindustri; Gruvindustri; ballastindustri; beräkningar;

   Sammanfattning : The mining and quarrying industries represent a highly important sector of the Swedish economy. The mining industry operates globally, whereas the quarrying industry operates on a regional/local basis. LÄS MER

7. 5. Set-up based operator training method in automated manufacturing: A joint production engineering and competence theory approach

   Författare :Peter Nordell; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production engineering; manufacturing competence; learning;

   Sammanfattning : Productivity improvement strategies such as increased automation, implementation of work cells and introduction of flexible work organisations have changed the content of operator work and the preconditions for training manufacturing competence. Traditional industrial training approaches have become increasingly obsolete. LÄS MER
