Abstract: <P>PROBLEM TO BE SOLVED: To determine optimum data synchronization order among a plurality of equipment.  <P>SOLUTION: Equipment names, connecting relationship and data changing equipment are inputted from an equipment connecting relationship conversion part 1 through a user interface 5. A synchronization optimization order determination part 2 sets respective pieces of equipment as vertexes, sets the connecting relationship as sides and prepares a directional graph to which directed sides from each start point based on each data changing equipment (vertex) to other vertexes are allocated. These vertexes are divided into vertexes in strong connection components including the data changing vertexes and other vertexes and the synchronization order is determined in the strong connection components on the basis of trace order based on depth priority search starting from one of the data changing vertexes in the strong connection components and the reverse trace order to fully synchronize the vertexes in the strong connection components. When synchronization order from the vertex in the strong connection component to a vertex other than the strong connection components, all the vertexes (whole equipment) can be fully synchronized. Since the synchronization order in the strong connection components is determined by the depth priority search, the data synchronization order can be determined optimally.  <P>COPYRIGHT: (C)2004,JPO
