A measured value table design unit (121) which: divides tree structure data into a plurality of subtrees in a manner such that the number of measuring instruments associated with each subtree is equal to or less than a number of table storage instruments, which is the upper limit number of measuring instruments that can store measured values in a measured value table; determines whether the divided subtrees are in an established state; and allocates measured value tables to the subtrees that are in an established state, said measured value tables storing the measured values from the measuring instruments associated with the subtrees. The subtrees that are not in an established state are further divided into a plurality of subtrees. |
