Flexible Factory Project

In manufacturing sites, the use of Information and Communications Technology (ICT) is increasing to enhance productivity under recent constraints such as shortage of skilled workers and change of work style. The following needs were raised by workers in manufacturing sites.

  • Monitoring the precise status of manufacturing equipment and inspection results on whether each process was completed correctly for quality control.
  • Ensuring stable communications among workers and production facilities including automated feeders and automated guided vehicles (AGVs).
  • Enabling flexible layout of machines and order of manufacturing processes to adapt to variable-type, variable-volume production and mass customization.

Wireless communication is one of the effective solutions to cover these needs. More and more wireless systems have been introduced with manufacturing equipment for status monitoring, product inspection, process management, environment sensing, machine control, and so on.

Instabilities of communication are already emerging concerns.

Due to interference between non-license requiring wireless systems operated independently, applications sometimes cannot secure enough bandwidth to maintain communication quality.

To address these issues technically, NICT has proposed the SRF Wireless Platform vision based on the concept of enabling coordination between a wide variety of wireless systems within the same facility for stable and efficient operation of an industrial system. Two of the private companies participating in the Flexible Factory Project are particularly committed to this vision, and in July 2017 they established the Flexible Factory Partnership Alliance (FFPA), a non-profit organization, to put it into practice.

Technical Description

SRF (Smart Resource Flow)

In the SRF platform, multiple wireless systems consisting of a gateway and several wireless devices are managed and controlled cooperatively by the field manager. In order to operate a variety of systems stably and effectively, the following tasks are performed.

Radio resources in frequency, time and space is assigned to each system by setting a control policy,

Management is performed cognitively by considering both the wireless communication conditions and factory applications.

Wireless environment is monitored on the SRF wireless platform.

In addition, each system is allowed to have autonomous internal control based on the control policy to adapt to rapid local change in the wireless environment (local control).
