The question of how a service consumer and a service provider should collaborate with each other in a business-to-business (B2B) setting is an ongoing research issue. The concept of electronic Sourcing (eSourcing) has been proposed as an integral concept with the EU research project CrossWork. The properties of eSourcing are explored, however, the question arises how a service consumer and a pr...

Various classes of finite-dimensional closed convex cones are studied. Equivalent characterizations of pointed cones, pyramids and rational pyramids are given. Special class of regular cones, corresponding to "continuous linear" quasiorderings of integer vectors is introduced and equivalently characterized. It comprehends both pointed cones and rational pyramids. Two different ways of determini...
