a set of pollutants. The structure of the elements of the A 9 identi er, identi es each

spatial cell ʩ ij with the type of the polluting enterprise.

5.8.3 A Subsystem for Statistical Decisions

A totality of units DMP and FOI performs the function of decision making about the
signal output for the user in correspondence with the a-priori prescribed elemental
structure of maximum concentration level (MCL). To preserve the generality, it is
assumed that MCL can be prescribed in each cell

ʩ ij or in some their totality by an
independent set of elements. This information contains the A 10 identi er.
