On Synthesis and Analysis of Generalized Work Flow Net Structures and Transition Graphs

Czaja L., Kudlek M.

Fundamenta Informaticae

Vol. 112, nr 1

39-45

We show that the results on analysis of net structures and transition graphs exhibited in [1] can be apllied also to generalized work flow net structures and related transition graphs.

Analysis and Synthesis of Net Structures and Transition Graphs

Czaja L., Kudlek M.

Fundamenta Informaticae

2009

Vol. 93, nr 1-3

97-110

We investigate relations between transition graphs and net structures. Whereas for a given net structure there always exists a reachability graph, the inverse problem to find a net structure for a given transition graph is not solvable in general. We present sufficient and necessary conditions for several classes of transition graphs such as general, pseudo-bounded, bounded and elementary transition graphs, corresponding to general and (pseudo-)bounded P/T nets or C/E nets. We also give maximal and minimal solutions within an algebraic structure of net structures. The entire investigation is formulated in the framework of multiset theory.

The paper presents investigations of heat transfer during boiling of water and ethanol on surfaces covered with complex net structures. The results obtained are in agreement with the results of the performed theoretical analysis.
