OPTIMAL PRODUCTION PLANNING METHOD IN MULTI-MOUNTER LINE FOR MANUFACTURING MULTIPLE PCBS, AND LINE PRODUCTION PLANNING APPARATUS

WIPO Patent Application WO/2019/168231

A1

The present invention relates to a line production planning method comprising the steps of: placing components according to a board priority, a component placement priority, an equipment priority, and a component feeder priority; calculating an equipment-specific production time and an entire line production time; configuring, as a preferential replacement object, a component feeder of equipment taking the longest calculated equipment-specific production time; repeating, by the predetermined number of times, the placing of the components to the calculating of the entire line production time; and determining, as final component placement, component placement taking the shortest entire line production time among respective results accordingly. Therefore, in a production line including multiple mounters and multiple component feeders for multiple types of boards, the present invention can provide production planning for producing all the assigned boards, and can provide the production order of boards and the placement of a common component feeder and a replacement component feeder through grouping of boards, which reduce a total production time.
