Abstract Changing the periodic cycle time of a manufacturing system leads to transient functioning. In this paper, we propose to determine a transient schedule due to the throughput rate modification of a manufacturing cell with operation time constraints. This modification does not require a new allocation of resources or a new sequence of tasks. This method uses a P-time Petri net as a model and, paradoxically, the properties of the periodic controlled functioning mode, in order to build the transient schedule. As the duration of the transient functioning can be bounded by an upper value, the transient temporal schedule is obtained by solving a linear program whose constraints stem from the P-time Petri net model. Disturbances in the input rate of the system are considered in order to specify the properties of the setting corresponding to the target throughput rate, but other criteria can be used.
