Upon reception of a retrieval request containing a retrieval key word from a client, a business flow registration information table is searched based on the retrieval key word to acquire a flow ID and a node ID of a business flow containing the retrieval key word. The flow ID and the node ID acquired are stored in a retrieval result table. With reference to a business flow operation history table, the node use count of the acquired node ID is divided by the flow use count of the acquired flow ID to calculate a node pass ratio. The calculated node pass ratio is stored in a node pass ratio table. With the node pass ratio as a score, the node pass ratio information is sorted in the descending order of the score. The retrieval request display data is generated in the order of sorting, and sent to the client.

A first, a second, and a third combustion region are defined by the air-fuel ratio of the mixture gas feeding combustion. Upon switching of combustion regions from the first combustion region to the third combustion region and from the third combustion region to the first combustion region, namely, when the second combustion region is passed, the mass of NOx emission downstream of an exhaust purifying device and the torque variation are estimated online. Based on the estimated value of the mass of NOx emission and the estimated value of the torque variation, the mass of intake air introduced into the combustion chamber is adjusted in a manner different from when normal, such as by changing the amount of lift of the intake valve, for example, so as to reduce the mass of NOx emission downstream of the exhaust purifying device and the torque variation below predetermined values upon passing of the second combustion region. Thus, the increase in exhaust emissions and the deterioration of operability during the switching of combustion regions can be suppressed.
