A model to optimize object management in cooperative work environment

In most manufacturing environments, data representing an object are scattered over multiple databases and shared by multiple sources. We refer to such a cooperative work environment as a multidatabase multisource (MDMS) data environment. One of the most important issues in a MDMS data environment is how to select a value for an object which has multiple records of values. We introduce a model by which optimal decision is made in terms of determining values for objects to manufacture.
