Claim One:
1. A method for tracking material through a production chain or operational process chain in which the material is transferred via a plurality of spatially distinct lumped masses of material, the method comprising: maintaining a dynamic state space descriptive of the plurality of spatially distinct lumped masses of material, wherein a quantity of entries in the dynamic state space is varied dependent on a quantity of spatially distinct lumped masses being tracked; maintaining a dynamic covariance matrix associated with the dynamic state space, wherein a dimension of the dynamic covariance matrix is varied dependent on a quantity of spatially distinct lumped masses of material being tracked; receiving one or more measurements relating to an observed lumped mass of material; and fusing the received one or more measurements into the dynamic state space and dynamic covariance matrix to provide an updated estimate of material in the plurality of spatially distinct lumped masses of material.
