1. 1. Hydronic Heating Systems The Effect of Design on System Sensitivity

   Författare :Anders Trüschel; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shunt group; controllability; district heating; room temperature; air heater; heating coil; thermal power output; deviations; water return temperature; valve group; hydronic heating; radiator system; P-band;

   Sammanfattning : This thesis starts from the recognition that a hydronic heating system can be optimised, but can never be totally perfect. Sooner or later, in practice, deviations - caused by one or more components having slightly different characteristics or settings than they are assumed or supposed to have - arise. LÄS MER

3. 2. Lean Visual Management of Deviations in Product Development and Production - Coining Physical, Digital, and Hybrid Pulse Methodology

   Författare :Onur Kaya; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lean management; Visualization; visual management; lean tools.; issue management; deviation management; disturbance management; lean;

   Sammanfattning : Lean is a relatively new trend, and every company strives for lean aiming for creating more output while using less input by focusing on the customer via eliminating non-value adding waste. Lean started at Toyota within its production system. From production, it started to be used in product development, and later on to other various sectors. LÄS MER

4. 3. Evaluating the Effects of Variation on Product Appearance through Visual Robustness

   Författare :Karin Nordvall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; product experience; visual quality appearance; visual sensitivity; optical quality; industrial design; perceived quality; craftsmanship; robust design; non-nominal visualization; geometrical variation; visual robustness;

   Sammanfattning : For consumer products where the product appearance plays an important role in meeting expectations, the visible effects of manufacturing variation can have a negative influence on the product experience. A concomitant of mass production is that no manufactured units are exactly identical, as a result of variation. LÄS MER

5. 4. Visual Robustness: Effects of Variation on Product Appearance and Perceived Quality

   Författare :Karin Nordvall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; craftsmanship; robust design; perceived quality; optical quality; visual quality appearance; visual robustness; geometrical variation and non-nominal visualization; industrial design;

   Sammanfattning : For consumer products where the product appearance plays an important role in meeting expectations, the visible effects of manufacturing variation can have a negative influence on the product experience. A prerequisite in mass production is that no manufactured units are exactly identical, as a result of variation. LÄS MER

7. 5. Towards Efficient Evaluation of Impacts of Geometrical Variation on Perceived Quality in Early Phases

   Författare :Ola S Wagersten; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Perceived Quality; variation simulation; visualization and evaluation; Geometrical variation; geometry assurance; non-rigid; tolerance analysis; product development;

   Sammanfattning : In a perfect world, manufacturing would lead to components without geometrical variation. This would mean that every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER
