Abstract:
A production management system which manages a) assembly data when one or more components are attached to a product under assembly, b) quality data regarding whether the quality of said product under assembly is good or bad, and c) check data obtained when said product under assembly is checked based on certain prespecified check items, when obtaining a finished product by attaching one or more components such as parts, units, or other finished products to said product under assembly on one or more of production assembly lines, said production management system comprising:a plurality of input sections, provided on said production and assembly lines, which input and output said assembly data, said quality data, said check data, management numbers with which each of said product under assembly can be identified, and group codes (named as names of product under assembly and a generic name of machine type codes) of said product under assembly obtained by dividing said product under assembly according to their types in a step of assembling said product under assembly and a checking step of checking said product under assembly according to said check items; a first storage section which stores said management numbers and said group codes input by said input sections in correlation with the date and time on which assembly of said product under assembly started and the date and time on which the assembly of said product under assembly is completed as assembly data; a second storage section which sequentially stores said check data in correlation with said management numbers and said group codes; a third storage section which sequentially stores said quality data in correlation with said management numbers and said group codes; a first display/selecting section which allows display and selection of group code of said product under assembly; a second display/selecting section which allows display and selection of a date and time; a third display/selecting section which allows display and selection of extraction conditions to extract desired data out of said check date and said quality data stored in said second and third storage sections and output information related to the extraction conditions; a retrieving section which retrieves and extracts data stored in said first, second, and third storage sections according to said group codes of said product under assembly, the specified date and time, and the output information selected by said first, second, third display/selecting sections; a fourth storage section which stores the information retrieved and extracted by said retrieving section; a data processing section which chronologically processes the data stored in said fourth storage section based on said group codes of said product under assembly, the specified date and time, and the output information selected by said first, second, third display/selecting sections; and a first display section which displays the data chronologically processed by said data processing section for each item to be output based on the output information.
