Title: Design for parallel skill based service systems.



Service systems with several types of customers and servers subject to a bipartite compatibility graph are in general quite intractable.  I will discuss tractable examples of such systems, and their relation to the simpler tractable model of FCFS bipartite matching, and present a conjecture, and a heuristic based on it, to answer problems of design for large scale general systems
