ABSTRACT:
A first storage in a system for progress management assistance stores production schedule data for a lot including: a production start time of the lot, described with a numerical value and/or a pointer; a production period for the lot, described with a numerical value; and a production finish time for the lot, described with a pointer and/or a numerical value that is obtained by adding the production period to the production start time. A second storage in the system stores an idle period table, in which an idle period between lots allocated to the same facility in the production schedule data is stored as a pair of a production finish time of a preceding lot and a production finish time of a following lot therein. An influence propagating device of the system reads actual result data of the production schedule data stored in the first storage, matches the actual result data with the production schedule data, propagates time data to the production schedule data and the idle period table via the pointers, and retrieves duplication of lots allocated to the same facility from the idle period table stored in the second storage. The influence propagating device propagates an alteration in time data to the production schedule data and the idle period table via the pointers by at least adding a duplicate period to a production start time of a following lot.
