14. Matrix Representation for A Set of Firings
Mt = Mo + A’Σ Ui (1)

15. An Adjacency Matrix

16. The Process An initial marking for the system is specified.
For each performance objective, a value is assigned to each blank place node in the system. The values added form a vector V of rank p.
The set of firings is specified.
The sum of values of the blank place nodes involved in the firings is the contribution that the firings make to the performance objective.

18. Matrix Analysis A = N + O (2) Mt = Mo + N’ΣUi + O’ΣUi (3)
Substituting into (1) we have
Mt = Mo + N’ΣUi + O’ΣUi (3)

19. Value Added
V.A. = V’O’ΣUi (4)
subject to
Mt = Mo + A’Σ Ui

20. Values on Transition Nodes: An Option
When values are on place nodes, they are counted even if subsequent courses are not taken.
Values can be placed on transition nodes.
Only one value per transition node. The values added form a vector W of rank t.
