Wireless Communication Management Model of Workshop and Warehouse Manufacturing System

With the development of global manufacturing organizations, some automobile body companies outsource blanking process to the professional factories which have decoiling & blanking & stacking production lines. In order to supply kinds of sheet-metal just in time, the blanking factories often have large-scale warehouse of nonstandard coils. So workshop-material-flow and warehouse management became a hot research issue. Traditional Manufacturing System has many defaults, such as, manual business process management, information flowing delay after material flowing, high mistakes ratio, stacking and crane job schedule in a state of chaos, very much production waste, and hard to manage the storage. After investigation and study of blanking factories, we propose an intelligent control of material flow base on wireless communication in sheet-metal blanking workshop and storage management System to solve the difficulties by following advanced manufacturing and management theories. With our prototype workers can use wireless PDA follow the intelligently instruction to do multi-process material-flow-job scheduling, calculation and allocation of storage space, storage monitor, and production execution monitor.Our work has been implemented and putted to use in a large-scale automobile sheet-metal blanking company, which improves automated administration level.
