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.

摘要:
A vector block information indicating a plurality of line segment rows is read out from a block map. Each line segment row divides an area of a block from an area of a road in an image drawing region. Each point at which one end of a line segment row contacts with a boundary line of the image drawing region is set as a boundary point. In this case, a road crossing the boundary line of the image drawing region is indicated by a pair of line segment rows having a pair of boundary points close to each other. To determine an area of the road, the pair of boundary points are connected with each other through a connecting line segment. Therefore, a road area in the image drawing region can be automatically extracted from the block map. In addition, an end area of the road placed at the boundary line of the image drawing region is reshaped to have two right-angle corners at the end area of the road, a length of a road area at the boundary line of the image drawing region is shortened, an area of a narrow road is deleted from the road area, an area of a narrow road is widened, or a plurality of blocks placed in an administrative district is unified by deleting areas of a plurality of roads dividing the blocks.
