Abstract

A program is disclosed to project dates and durations for processes and subprocesses based upon a user defined calendar. This program derives start/end, date sets given either a starting or an ending date. In addition, a total duration value(the longest path through the process) is derived. The date values are derived from a user defined calendar. This particular calendar is non-perpetual; so, there is an added requirement to default to a 24 x 7 work week in a calendar's absense. Example 1 A calendar may be defined from 1/1/2001-12/31/2001. If the process for which dates were being calculated span either the start or end of that calendar, the program defaults to and continues to derive dates and durations based upon a 24x7 work week.
