In various cases users need to transform a process model into a matrix representation for further analysis. In this paper, the authors introduce the notion of Order Matrix, which enables unique representation of block-structured process models. They present algorithms for transforming a block-structured process model into a corresponding order matrix and vice verse. They then prove that such order matrix constitutes a unique representation of a block-structured process model; i.e., if they transform a process model into an order matrix, and then transform this matrix back into a process model, the two process models are trace equivalent; i.e., they show same behavior. Finally, they analyze algebraic properties of order matrices.
