A variety of problems in operations research, performance analysis, manufacturing, communication networks, etc. can be modelled as discrete event systems with minimum and maximum timing constrains.
Research is focussed on the existence of structural fixed points of bipartite systems.
We also examine the ordinary fixed points of bipartite systems that do not have a structural fixedpoint. And prove some conjectures about the structure and properties of bipartite systems, which satisfies the nondegeneracy assumption. The existence of fixed points useful for knowing the evolution of systems.
