Direct Granularity Conversions among Temporal Constraints
This paper considers temporal constraints that can impose a minimum
and maximum time distance between the occurrences of two events by specifying the
minimum and maximum values in terms of a time granularity.When several constraints
using different time granularities are part of the specification of a single problem, a
reasonable question is how to convert the constraints in terms of a single granularity
in order to apply standard temporal constraint algorithms. This paper investigates the
problem of converting a distance constraint expressed in terms of a granularity into
another one in terms of a different time granularity. An expressive formal model for
time granularities is assumed including common granularities like hours and days as
well as user-defined granularities like business days and academic semesters
