The invention discloses a management method and system for parts in a production process. The system comprises a display device, an input device and a control module, the display device is used for displaying numbers of parts, order numbers, placement container numbers and retail quantity in containers, the input device is used for inputting related parameters and selecting container placement modes, and the control module is used for giving placement container parameters of the parts according to the states of the placement containers of the parts and the placement modes of the containers; the management system applies the management method to manage the placement of the parts. Parts, orders and containers are numbered; according to the method, the part placement mode and priority are set, after the parts are generated, whether containers capable of containing the parts exist or not is checked according to the priority of the part placement mode, if not, a new container is set to contain the parts, orderly management is conducted on placement of the parts, multi-order combined production and alternate typesetting of the large parts and the small parts are achieved, and the material utilization rate is increased.
