In an effort to develop breakthrough technologies that enable drastic reduction in CO2 emissions from steel industry (ULCOS project), the reduction of iron ore by pure hydrogen in a direct reduction shaft furnace was investigated. After experimental and modelling studies, a 2D, axisymmetrical steady-state model called REDUCTOR was developed to simulate a counter-current moving bed reactor in wh...

Real world problems are often overconstrained, ill-deened, or tolerate good though suboptimal solutions as long as those are found before a deadline. Such problems are often called partial constraint satisfaction problems (PCSPs). The model for PCSPs was initially inspired by classic constraint satisfaction methods. Another path leading to comparable notions and originating from fuzzy decision ...

We present a scheduling methodology for applications where the generation of schedules is constrained by antagonistic and vague knowledge. Besides temporal and capacity constraints, compatibility constraints between consecutive jobs are managed. We model the vague constraints and uncertain data by fuzzy set theory. The importance of single jobs and and the difficulty to schedule them is defined...
