Abstract

A method and apparatus for scheduling appointments in a manufacturing process flow are disclosed. The method and apparatus include a number of aspects including appointments in which processing windows float within commitment windows; appointments in which the processing windows include consumption and processing intervals and in which the processing windows can overlap with the processing interval of other appointments; the use of different kinds of calendars including different types of appointments maintained in a variety of states; a calendaring system in which appointments are constrained by the implicit constraints not represented by booked appointments as well as the explicit constraints represented by booked appointments; calendar manipulation techniques used in managing the calendars; and corresponding appointments maintained over multiple calendars in a synchronized manner.

booking a second processing appointment on the calendar;

defining a first portion of the second booked appointment as a second consumption interval; and

defining a non-overlapping portion of the second booked appointment as a second processing interval.

21. A method for calendaring appointments, comprising:

explicitly constraining an appointment with the presence of another appointment booked on the same calendar; and

implicitly constraining an appointment with at least one attribute representing a constraint that may not be associated with any other appointment on the same calendar.

22. The method of claim 21, wherein explicitly constraining the booking of the new appointment includes explicitly constraining an appointment from shifting to an earlier start time by an earlier booked appointment on the same calendar or explicitly constraining the appointment from shifting to a later start time by a later booked appointment on the same calendar.

23. The method of claim 21, wherein implicitly constraining an appointment includes implicitly constraining the earliest start time of an appointment with at least one attribute representing a transport delay, a loading delay, a setup delay or the current time.

24. The method of claim 21, wherein implicitly constraining an appointment includes implicitly constraining the shifting of the appointment or separation between the appointment and a previous appointment with at least one attribute representing an unloading delay or a discharge duration.

25. A method for calendaring appointments, comprising:

booking a first appointment on a first calendar;

booking a second appointment corresponding to the first appointment on a second calendar; and

synchronizing changes to the first and second appointments responsive to events in a process flow.
