Data model for supply chain planning

A computerized system for storing, managing and processing of a supply chain planning information by a supply chain planning application program, said system comprising:

• a computer with memory for storing an input data containing supply chain planning information about at least one resource, said input data being inputted, stored and organized in said memory, wherein said organization of said input data comprises the steps of:
• a) dividing said input data into plurality of activities, each one of said plurality of activities representing an individual working step in a production process;
• b) grouping said plurality of activities into plurality of orders, wherein related activities within same order are linked together into at least one network, each of said related activities referencing all immediately preceding and -all immediately following activities in chronological sequence;
• c) providing a direct link to a first and last activity within each said order, said direct link stored in a computer memory for access by supply chain planning application program during runtime;
• d) providing at least one input interface node for each said order, wherein said input interface node represents a material consumed by said order, each input interface node being linked to all activities that consume said material;
• and
• e) providing at least one output interface node for each said order, wherein said output interface node represents a material created by said order, each output interface node being linked to all activities that create said material;
• wherein each output interface node of a first order of said plurality of orders is linked to reference a respective input interface node of each subsequent order of said plurality of orders, scheduled to consume the material associated with said output interface node of said first order;
• and
• at least one application program for accessing and processing said data for supply chain planning, wherein said application program utilizes said direct links stored in said computer memory for access to said first activity of a desired order within said plurality of orders, and thereafter utilizing said links among said related activities within the same order for scheduling preceding and subsequent activities in chronological sequence,
• whereby allowing said supply chain planning application to determine and schedule efficiently all orders for a given resource in proper chronological sequence.

• c) providing a direct link to a first and last activity within each said order, said direct link stored in a computer memory for access by supply chain planning application program during runtime;
• and
• at least one application program for accessing and processing said data for supply chain planning, wherein said application program utilizes said direct links stored in said computer memory for access to said first activity of a desired order within said plurality of orders, and thereafter utilizing said links among said related activities within the same order for scheduling preceding and subsequent activities in proper chronological sequence,

• d) grouping a plurality of said activities within at least one order as at least one operation;
• e) providing for each said operation a pre-assigned operation number;
• at least one database table having an entry for each object identity and containing said pre-assigned operation number defining at least one operation to be performed on said object, said table further comprising a lined reference to the earliest activity for said respective defined operation on said object;
• and
• at least one application program for accessing and processing said data for supply chain planning, wherein said application program utilizes said direct links stored in said computer memory for access to said first activity of a desired order within said plurality of orders, and thereafter utilizing said links among said related activities within the same order for scheduling preceding and subsequent activities in proper chronological sequence.
