Abstract

A method for continuous real-time management of heterogeneous interdependent resources is described. The method preferably comprises using multiple distributed resource engines to maintain timely and precise schedules, and action controls, and identifying and responding to rapidly changing conditions in accord with predetermined requirements, relationships, and constraints. Each resource engine continuously adjusts schedules in response to changing status, resource requirements, relationships and constraints. Each action control maintains an ordered list of conditions requiring action, determines the best action in each case, and generates appropriate responses. Preferably methods for continuous operation include inquiring about status concurrent with scheduling activity and recognizing the effects of time passage on the condition of schedules.

Claims

1. A method for continuous resource management of events for a multitude of predetermined heterogenous resources with complex interrelationships by scheduling and controlling actions, said method comprising:

(a) providing memory for permanent and temporary data files;

(b) providing a resource engine for each predetermined resource for continuously performing prospective scheduling;

(c) providing an action control for each management function;

(d) providing a router;

(e) providing a processing unit for operating the resource engine, the action control and the router;

(f) providing into the memory information about each resource comprising resource characteristics, rules for resource use, and relationships with other resources for permanent data files;

(g) initializing the resource engine with independent demand and current conditions;

(h) continuously monitoring with the resource engine changes in independent demand and conditions using data from external agents and providing instructions to an action control; and

(i) using the action control to determine actions to be taken based on resource information and changes and providing instructions to a resource engine;

(j) the router managing, logging and certifying delivery of instructions from and between resource engines, action controls, and external agents;

wherein the temporary data files are used by the resource engine and the action control to store temporary data.

2. The method for continuous resource management according to claim 1, wherein data integrity of the resource engine is monitored by the steps of:

(a) initializing control information;

(b) providing an audit history and control information;

(c) evaluating the audit history and control information to determine the state of processing for the resource engine; and

(d) generating instructions to correct dependent demand event errors.

3. The method for continuous resource management according to claim 1, wherein the resource engine performs prospective scheduling by the steps of

(a) processing command primitive message syntax, macros and keywords either to change system control tables or to create internal transactions;

(b) determining a sequence in which resource processing is performed;

(c) combining descriptions of dependent changes and parent demand changes to determine dependent demand changes;

(d) updating resource demands, rules and status;

(e) balancing supply and demand events;

(f) defining dependent changes; and

(g) defining a time trigger.

4. The method for continuous resource management according to claim 1, wherein the resource engine determines when a resource condition will change by the steps of:

(a) initializing an ordered time trigger list;

(b) providing a time trigger for each resource when evaluated;

(c) providing under cooperative control a periodic check for any resource time trigger less than present time for addition to a list of resources to be processed; and

(d) regenerating the ordered time trigger list.

5. A method for continuous resource management according to claim 1, wherein the resource engine adjusts supply order timing by the steps of:

(a) aligning supply events within intervals as defined by alignment parameters;

(b) adjusting supply event time to earlier intervals to satisfy rules for resource use; and

(c) determining when available capacity is exceeded.

6. A method for continuous resource management according to claim 1, wherein the resource engine provides precise lead time offset modeling by a method comprising the steps of:

(a) determining a lead time transform either by evaluating routings, overlaps and complex factors, and historical process data or by explicitly defining a lead time transform; and

(b) determining dependent demand amounts from parent supply amount by said transform.

7. A method for continuous resource management according to claim 1, wherein the resource engine provides precise conversion between parent supply and dependent demand amount by a method comprising the steps of:

(a) establishing dependent amount formulas and coefficients;

(b) determining conversion factor and option values by formula or explicit definition; and

(c) determining dependent demand amount from parent supply amount, factor and option values.

8. A method for continuous resource management according to claim 1, wherein the resource engine creates and changes dependent demands by a method further comprising:

(a) providing a transaction defining the parent to dependent relationship;

(b) providing a reference to parent supply events; and

(c) combining said transaction with every supply event.

9. The method for continuous resource management according to claim 1, wherein the action control further provides means for managing actions in a timely manner by a method comprising:

(a) receiving notification of an action item that requires a response;

(b) providing a list of action items arranged by user defined priorities;

(c) providing a detail schedule of events that identifies sources of requirements;

(d) determining alternative solutions for each selected action item;

(e) producing changes required for a chosen solution;

(f) taking action automatically as specified in user defined options;

(g) reminding an user of any deferred action;

(h) Focusing and directing analysis based upon previous context; and

(i) communicating with other users by messages that automatically generate context and problem analysis references.

10. A method for continuous resource management according to the method of claim 1, further comprising providing multiple rule sets on a common time horizon creating resource supply events that provide both near horizon details and far horizon summary information.

11. A method for continuous resource management according to claim 1, wherein the resource engine combines capacity and materials management by a method comprising the steps of:

(a) defining resource schedule events;

(b) balancing resource supply and demand; and

(c) converting between diverse resource units of measurement.

12. A method for continuous resource in accord with the method of claim 1, the method further comprising providing concurrent inquiry and update of schedule information while maintaining data consistency, integrity, and fault tolerance.
