A prediction control method and apparatus. A value of at least one parameter representing a condition of an object to be controlled at predetermined intervals is detected and added to a history of the parameter stored in a storage device. The histories of the parameters from the storage device are read and whether each history satisfies a predetermined condition is judged. The history judged as satisfying the predetermined condition is stored to the storage device as warning data. A warning signal is generated in response to the judged histories.

A method for predictively generating a warning information, comprising the steps of: a) detecting a value of at least one parameter representing a condition of an object to be controlled at a predetermined time interval, and adding the detected value to a history of one of the at least one parameter

A method for predictively generating a warning information, comprising the steps of: a) detecting a value of at least one parameter representing a condition of an object to be controlled at a predetermined time interval, and adding the detected value to a history of one of the at least one parameter; b) preparing at least one first layer, each of the at least one first layer including a graph representing the history of one of the at least one parameter having an axis representing time; c) preparing at least one second layer, each of the at least one second layer corresponding to one of the at least one first layer and being divided into a plurality of elements each having a data value of 1 or 0, the data value of each of the plurality of elements being determined based on a positional relationship between the graph in each of the at least one first layer and the plurality of elements in each of the at least one second layer; d) preparing a third layer from the at least one second layer, the third layer being divided into a plurality of elements each having a data value of 1 or 0, the data value of each of the plurality of elements being determined as a logical OR of all of the data values of the corresponding elements of the at least one second layer; e) preparing a fourth layer from the third layer and a warning layer stored in a storage means, the fourth layer and the warning layer each being divided into a plurality of elements each having a data value of 1 or 0, the data value of each of the plurality of elements being determined as a logical AND of the data values of the corresponding elements of the third layer and the warning layer; f) judging whether a ratio of the number of elements having a data value of 1 in the fourth layer to the total number of the plurality of elements in the fourth layer exceeds a predetermined value; g) storing the data values of the third layer as the data values of the warning layer in the storage means in accordance with a result of the judging in step f); and h) generating a warning information in accordance with a result of the judging in step f).
