<p>PROBLEM TO BE SOLVED: To completely tie up data on a lot when a large number of divided events are caused over a large number of processes. SOLUTION: A data analysis support system 1 automatically gathers process data of a process control system and measuring data of a manufacturing device 23, and stores gathered data in a relational database, and outputs a document or a graph of the data unitarily controlled according to a demand from an operator. When the process data and the measuring data are stored in the relational database, an event such as division and derivation is considerd. For example, an event to divide a lot (a') from a lot (a) is caused in a beginning condition between processes A and B, since a master lot of a lot (a) is the lot (a) in both processes A and B, when a document or a graph is outputted, the process data and the measuring data of the lot (a) are referred as they are, on the one hand, in the case of the lot (a'), since a master lot is registered as the lot (a) in the process A, the process data and the measuring data attached to the lot (a) are referred.</p> |
