Concurrency control is the action of synchronizing operations issued by concurrently executing programs on a shared database. Concurrency control (CC) is the key concept for proper transactions on objects to avoid any loss of data or to ensure proper updating of data in the database. This paper presents the development of Fuzzy Logic for concurrency management while modeling Bolted connection drawing using Autodesk inventor 2008. While implementing concurrency control, this work ensures that adjacent shapes in the drawing cannot be accessed by more than one person. The Fuzzy Logic learns the objects and the nature of transactions to be done based a threshold value. Learning stops once all the objects are exposed to Fuzzy Logic. We have attempted to use Fuzzy Logic for storing lock information when multi users are working on same Bolted connection drawing.
