Embodiments of the present application provide a method, device and processor for determining a target process of a product. The method comprises: after the product is put into a corresponding
production line for production, obtaining a plurality of historical operation durations of the
production line; determining a plurality of target operation durations that meet a preset condition from the plurality of historical operation durations; dividing the plurality of target operation durations according to a
process type of each process of the
production line at a
current time, to obtain a first target operation duration corresponding to each process; for any one process, fitting the first target operation duration of the process by using a preset fitting mode, to obtain a fitting function of the process; determining a second target operation duration of the process according to the fitting function of the process; and determining a process corresponding to a second target operation duration with the largest value as a target process of the product at the
current time. The above technical solution can more accurately locate the target process, is conducive to the management of product production, reduces the management cost, and improves the production efficiency.
