From here the designer places the operational features and the structural beams, which avoid obstacles using structural integrity criteria as a guide.
As such, the per formance of the design development process can be improved through both the strategic and operational levels of management.
Since the latter typically begins during the third year of life, the implication is that countering processes must be operational by then.
The issue of operational correctness is largely ignored in functional programs and remains an open problem.
In order to compare his results with ours, we present a brief account of an operational semantics for annotated terms.
If only computable domain-theoretic primitives are used, a simple operational semantics results as a by-product of the design process.
The operational semantics of expressions is given by a reduction relation i-> on descriptions (denned below).
In section 3 we give three equivalent definitions of operational approximation and equivalence.
