PURPOSE:To decide an optimum mounting order simply and in a short time and to easily deal with even a change in various mounting conditions by a method wherein, on the basis of a condition which decides a mounting order, a mounting region is divided continuously until an optimum condition becomes self-evident, self-evident mounting orders are joined and the whole mounting order is decided. CONSTITUTION:In order to satisfy a condition to make the total movement distance between mounting points shortest, a mounting region on a printed-circuit board is divided into two region as a region 4 and a region 5 in the X-direction so as to halve the number of mounting points P by a dividing line 1. Then, the divided regions 4, 5 are divided into two each in the same manner, and a division processing operation is repeated until the mounting order which reduces the movement distance between mounting points P, P to a minimum becomes self-evident. As a result, the mounting points P inside each region are reduced to two points or three points, the mounting order becomes a triangle or a line segment, and the mounting order inside each region becomes self-evident. Then, the divided regions are united reversely until the divided regions vanish, the region 4 and the region 5 are united lastly and the mounting order of all the mounting points P is decided. |
