Abstract

An instantaneous, event driven diagramming method is provided which identifies discrete events within various activities performed during the course of a project and interrelates such events, where applicable, according to the timing and/or functional relationship between such events. An event driven diagram generated in accordance with the method of this invention may be used with CPM, and may be read by a computer employing standard algorithms to determine the critical path of the project.

Claims

1. A diagramming method for project planning, comprising:

(a) identifying activities which need to be carried out to complete a project;

(b) assigning discrete events to each activity in such a way that each event in the project is uniquely identified;

(c) relating each event to at least one other event, and assigning a duration to the relationship between related events.

2. The method of claim 1 in which step (b) comprises:

(i) providing a library of events;

(ii) providing a listing of activities for the project;

(iii) assigning at least one event from said library of events to each of said activities, the combination of said at least one event with a particular activity creating a unique identification for said at least one event.

3. The method of claim 1 in which each of said events is representative of an instantaneous point in time.

4. The method of claim 1 in which step (c) comprises relating each event to a succeeding event.

5. The method of claim 4 in which step (c) comprises assigning a duration to the relationship between successive events.

6. A diagramming method for project planning, comprising:

(a) identifying activities which need to be carried out to complete a project;

(b) assigning discrete events to each activity in such a way that each event in the project is uniquely identified;

(c) relating each event within each activity to at least one other event in said activity, and assigning a duration to the relationship between related events;

(d) interrelating an event from one activity with an event from another activity.

7. The diagramming method of claim 6 in which step (b) comprises updating the assignment of discrete events during the course of the project within one or more activities to account for occurrences which were initially unplanned.

8. The diagramming method of claim 6 in which step (c) comprises assigning a duration to the relationship between each updated event added in step (b) and a related event within said one or more activities.

9. The diagramming method of claim 6 in which step (d) expresses the interrelationship of events within different activities on the basis of the time at which they occur within the project regardless of whether or not said events are otherwise related to one another.

10. The diagramming method of claim 6 in which step (c) comprises assigning an updated duration to the relationship between related events which are subject to a delay and recording the occurrence of said delay on a periodic basis.

11. The diagramming method of claim 10 in which step (c) comprises assigning an updated duration to the relationship between related events which are subject to an acceleration and recording the occurrence of said acceleration on a periodic basis.

12. The diagramming method of claim 11 in which step (c) comprises recording the cumulative losses due to delays and the cumulative gains due to acceleration on a periodic basis.

13. The diagramming method of claim 6 in which step (c) comprises assigning an updated duration the relationship between related events which are subject to a revision of the plan.

14. The diagramming method of claim 13 in which step (c) comprises recording an inception date for each of said events which is subject to said revision of the plan.

15. The diagramming method of claim 14 in which step (c) comprises separating the cumulative total of said updated duration between related events which are subject to a revision of the plan from a cumulative total of updated durations between related events which are subject to a delay or to an acceleration.

16. The diagramming method of claim 6 in which at least some of said events are active at a given point in time and at least some of said events are not active at said given point in time, said diagramming method further including step (e) comprising recording the occurrence of active events as they become completed on the day said occurrence takes place.

17. The method of claim 6 in which step (b) comprises:

(i) providing a library of events;

(ii) providing a listing of activities for the project;

(iii) assigning at least one event from said library of events to each of said activities, the combination of said at least one event with a particular activity creating a unique identification for said at least one event.

18. The diagramming method for project planning, comprising:

(a) identifying activities which need to be carried out to complete a project;

(b) assigning discrete events to each activity in such a way that each event in the project is uniquely defined;

(c) relating each event within each activity to at least one other event in said activity, and assigning a duration to the relationship between related events;

(d) interrelating the occurrence of an event from one activity with the occurrence of an event from another activity;

(e) expressing when each event within each activity has occurred, whereby the critical path of the project may be calculated on a continuous basis as the project progresses.

19. The diagramming method of claim 18 in which step (b) comprises updating the assignment of discrete events during the course of the project within one or more activities to account for occurrences which were initially unplanned.

20. The diagramming method of claim 18 in which step (c) comprises assigning a duration to the relationship between each updated event added in step (b) and a related event within said one or more activities.

21. The diagramming method of claim 18 in which step (d) expresses the interrelationship of events within different activities on the basis of the time at which they occur within the project regardless of whether or not said events are otherwise related to one another.

22. The diagramming method of claim 18 in which step (c) comprises assigning an updated duration to the relationship between related events which are subject to a delay and recording the occurrence of said delay on a periodic basis.

23. The diagramming method of claim 22 in which step (c) comprises assigning an updated duration to the relationship between related events which are subject to an acceleration, and recording the occurrence of said acceleration on a periodic basis.

24. The diagramming method of claim 23 in which step (c) comprises recording the cumulative losses due to delays and the cumulative gains due to acceleration on a periodic basis.

25. The diagramming method of claim 18 in which step (c) comprises assigning an updated duration to the relationship between related events which are subject to a revision of the plan.

26. The diagramming method of claim 25 in which step (c) comprises recording an inception date for each of said events which is subject to said revision of the plan.

27. The diagramming method of claim 26 in which step (c) comprises separating the cumulative total of said updated duration between related events which are subject to a revision of the plan from a cumulative total of updated durations between related events which are subject to a delay or to an acceleration.

28. The method of claim 18 in which step (b) comprises:

(i) providing a library of events;

(ii) providing a listing of activities for the project;

(iii) assigning at least one event from said library of events to each of said activities, the combination of said at least one event with a particular activity creating a unique identification for said at least one event.
