Abstract:
1. An operating condition monitoring apparatus that monitors the operating condition of one or more production apparatuses, comprising: a load-time information acquisition unit for obtaining load-time information, of the one or more production apparatuses, concerning load time allocated to production within a predetermined period; an operating-time information acquisition unit for obtaining operating-time information, of the one or more production apparatuses, concerning operating time within the predetermined period, the operating time being the time the production apparatuses are in an operable state; an individual operating-rate calculation unit for calculating an individual operating rate of the one or more production apparatuses by dividing the operating time indicated in the operating-time information by the load time indicated in the load-time information; an output unit for outputting the individual operating rate; a state-information acquisition unit for obtaining state information, of the one or more production apparatuses, concerning an initiation time and termination time of each of states including a normal operating state, an abnormal stop state, a manual stop state, and a stop state caused by work; and a time-information structure unit for calculating downtime caused by the production apparatus itself, of one or more production apparatuses, by adding the time of the abnormal stop state obtained from the state information and the time of the manual stop state that comes immediately after the abnormal stop state and is obtained from the state information, and calculating downtime caused by another production apparatus by adding the time of the manual stop state obtained from the state information and the time of stop state caused by work that comes immediately after the manual stop state and is obtained from the state information, for preparing the load-time information indicating the sum total of the time of the normal operating state obtained from the state information, the downtime caused by the production apparatus itself and the downtime caused by the other production apparatus, and preparing the operating-time information indicating the sum total of the time of the normal operating state and the downtime caused by the other production apparatus.
