Abstract

Proposed is a scheme to represent more complex relationships between manufacturing materials than that which exists in the conventional, rigid, Bill of Material (BM) relationship. It permits a BM data base to fully support a manufacturing structure where more than one end product results from a pool of various ingredients or components. The benefits are new flexibility and greater robustness over the basic "production order" BM structure of most MRP systems.

Logistic Transaction Data Structure

      Proposed is a scheme to represent more complex relationships
between manufacturing materials than that which exists in the
conventional, rigid, Bill of Material (BM) relationship.  It permits
a BM data base to fully support a manufacturing structure where more
than one end product results from a pool of various ingredients or
components.  The benefits are new flexibility and greater robustness
over the basic "production order" BM structure of most MRP systems.

      Many BM systems and Material Resource Planning (MRP) systems
limit themselves to representing simple assemblies (e.g., where parts
A, B and C are assembled together to make part Z) rather than complex
scenarios where A B and C are combined together with the result being
part X and part Y.  Examples of the latter may be found in industries
concerned with the processing of raw materials.  More generally, this
situation also arises in salvaging good parts from rejected
assemblies.  The limitation is one of the data structure that can be
supported by the system.  Systems using this limited structure are
themselves of limited application.

      This invention is a logical data structure which will
accommodate more complex forms of relationships between manufactured
parts than the traditional.  It also accommodates 'traceability' -
the requirement to identify the source of a manufactured item at all
stages in its life.  This need is found particularly in the
pharmaceutical, aerospace and defence industries.  This data
structure can be:

o   incorporated as part of a larger data structure for a
    manufacturing system,

o   used as the main input for database design for a BOM or MRP
    system,

o   used as the main input for process design for a BOM or MRP
    system.
