    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Combinatorial Slice Theory; Partial Order Theory of Concurrency; Digraph Width Measures; Equational Logic;

    Abstract : Slices are digraphs that can be composed together to form larger digraphs.In this thesis we introduce the foundations of a theory whose aim is to provide ways of defining and manipulating infinite families of combinatorial objects such as graphs, partial orders, logical equations etc. READ MORE

  6. 4. A model of contextual factors and inter-organizational integration : A Ground Theory study of two supply chains

    Author : Hana Hulthén; Dag Näslund; Helena Forslund; Teknisk logistik; []
