PROBLEM TO BE SOLVED: To automatically generate a repeatedly executable sequence used for sequence control of an automated system which produces a plurality of pieces of the same articles.SOLUTION: A sequence generation method includes: a step A for generating a plurality of start states; a step B for generating an end state corresponding to the start state so that a repeatedly executable sequence can be generated with respect to the generated plurality of start states; a step C for, according to a precondition of operation of sequence control and an operation condition regulating an effect of each operation and time required for operation, generating a sequence which starts in the generated start state and ends in the end state corresponding to the start state; and steps for repeating the steps A through C more than once and, when a predetermined number of different sequences from each other are generated by repeating the steps A through C more than once, selecting a sequence having the shortest processing time from among the generated different sequences.SELECTED DRAWING: Figure 1 【課題】同一の製品を複数個製造する自動化システムのシーケンス制御で用いる繰り返し実行可能なシーケンスを自動的に生成する。【解決手段】開始状態を複数生成するステップＡと、生成された複数の開始状態に対して、繰り返し実行可能なシーケンスが作成されるように当該開始状態に対応する終了状態を生成するステップＢと、シーケンス制御の動作の前提条件と、各動作の効果と、動作に要する時間とを規定する動作条件に従って、生成した開始状態で開始し、開始状態に対応する終了状態で終了するシーケンスを生成するステップＣと、ステップＡからステップＣのステップを複数回繰り返すステップと、ステップＡ乃至ステップＣが複数回繰り返されることで、所定数の異なるシーケンスが生成されると、生成された複数の異なるシーケンスから、処理時間が最小のシーケンスを選択するステップとを有する。【選択図】図１
