On Reduction of Production Disturbances in Manufacturing Systems Based on Discrete-Event Simulation

Popular Abstract in Swedish Förbättrad effektivitet i tillverkningssystemen för att åstadkomma förbättrad output och sålunda reducera tillverkningsstörningarna är ett viktigt område. Händelsestyrd simulering kan visualisera och studera de dynamiska förloppen relaterade till total effektivitet i tillverkningssystemen. En metodik för reducering av produktionsstörningar är presenterad. Förbättringar Improved efficiency in manufacturing systems to achieve increased output and thus reduced production disturbances is a vital area. DES (Discrete-Event Simulation) can visualize and study the dynamic issues related to total efficiency in manufacturing systems. A methodology for production disturbance reduction is presented. Increased performance of manufacturing systems means not only enhanced valu

Numerical quantification of water saturation, back diffusion, electro-osmotic drag and water generation in polymer electrolyte membrane fuel cells

A 3D unit cell has been simulated numerically using a commercial software in order to evaluate and quantify various water related phenomena, i.e., electro-osmotic drag, back diffusion, electro-chemical water generation and the saturation effects in the porous media. The water saturation effects were noticed to be more pronounced in the GDL of the cathode as compared to the catalyst layer due to gr
