Industrial Social Network for Zero Defect Manufacturing

Project Details and Motivation

Zero Defect Manufacturing (ZDM) is intrinsically a multi-disciplinary approach. It requires parallel progress of different technological pillars, including sensor devices, quality inspection systems, industrial informatics, data analytics and knowledge management. A lot of attention is given towards implementing analytics such ML, reg. analysis etc., upon timeseries data collected in production processes. Textual data types that capture the knowledge and experience of people working in manufacturing workplaces, addressing, and solving quality issues, can be very useful for ZDM needs. Industrial Social Network (ISN) solutions can be very efficient for serving communication needs in a manufacturing setting as they allow for informal communication, that is more appealing to the users, regarding formal incidents, events, etc. occurring in a workplace, as well as the exchange of best practices; such solutions capturing informal knowledge from employees in the shopfloor combined with IIoT data coming from IIoT platforms, can prove very valuable in servicing ZDM objectives.

WEP, in the context of H2020 project MANUWORK led by LMS, has developed the RAPpID ISN solution (see Figure 1) which is used by working personnel involved in the manufacturing process (engineers, line operating levels, maintenance personnel, etc.), allowing knowledge sharing of past and new best practices for line operations, sharing of recent lessons learnt as well as improving the connectivity and socializing among employees and line operators working in the production area, and  engineers/other experts working in other parts of the manufacturing plant, or even outside (e.g., suppliers, other colleagues in other facilities of the company, etc.), in order to raise immediate problems, seeking to solve them, and reducing hence downtime, improve quality and reduce production losses.

The objective of ISN4ZDM is the integration of RAPpID ISN to ZDMP to extend ZDMP with an additional “component” that provides new knowledge-based services towards ZDM.

ZDMP Fit

RAPpID complements existing ZDMP functionality with new capabilities that are geared towards combining employees’ tacit knowledge with IIoT data (events, incidents, analytics, etc.) that are typically used for ZDM purposes. RAPpID benefits from the integration with ZDMP both from business but also from technology aspects. RAPpID, through its integration to ZDMP, can gain access to a large potential customer base of ZDMP. Moreover, by integrating RAPpID to ZDMP, “data in motion” or “data at rest” managed by ZDMP can be accessible to RAPpID users via RAPpID dashboards, allowing employees to use typical social network functions such as comment, discuss, “like”, post, etc., upon these IIoT based events. Textual input from users can be combined with IIoT data in a knowledge database implemented by LMS using semantics and ontology technology.

ISN4ZDM project has identified two key objectives:

  1. Extend the functionality of RAPpID ISN solution with a knowledge base that aims to link IIoT/machine data typically generated in some manufacturing environment with textual information typically available in ISN solutions such as RAPpID. This objective fits with the ZDMP ecosystem that provides applications and components to assist manufacturers. In other words, the business objective of ISN4ZDM fits with the business objectives of ZDMP ecosystem.
  2. To increase the impact towards the manufacturing community, ISN4ZDM has identified several ZDMP components to integrate (see following list), fostering the extension of the ZDMP ecosystem with additional and unique functionalities offered by ISN4ZDM, and increasing the capability of ISN4ZDM to penetrate the ZDMP market, thus being a win-win case for both ZDMP and ISN4ZDM.
    1. Portal: Facilitates access to ZDMP.
    2. Secure Authentication and Authorisation: Single Sign On to RAPpID and ZDMP.
    3. Data acquisition: Data access, exchange and analytics with ZDMP, for IoT extracted data.
    4. Service and Message Bus: ‘Listening’ and communicating critical events to RAPpID, facilitating “data-in-motion” exchange with ZDMP.
    5. Application Run-time: Container-based orchestration and hosting of components.
    6. Marketplace: To offer and access RAPpID in cloud through the ZDMP ‘Marketplace’.

Integration of the “Portal” and “Secure Authentication and Authorization” (SA&A) components of ZDMP has a two-fold objective. First, providing access to RAPpID directly from the ZDMP portal, similar to other zApps. Second, allowing the use of Single Sign-On (SSO) mechanism offered by the SA&A mechanism to provide access directly to RAPpID for a user (RAPpID “licenced” user) authenticated by the “Portal”. Data is sent to the “Data Acquisition” component that is used for handling data from IoT sensors and other sources as “it allows the connection to different kind of data sources”. The data from the “Data Acquisition” is transferred to the “Service and Message Bus” component that provides a standardized communication interface to exchange messages, events, and data. This message bus implements a publish/subscribe messaging concept which allows the connected components to broadcast (publish) information on specific topics and to listen for certain events and topics (subscribe)”. “RAPpID ZDM connector” listens to specific topics in order to store data in the RAPpID internal MongoDB database and eventually provide this data to RAPpID end-users through the ZDM-DBoard. Data available in the RAPpID system is available through SQL connection to the ZDM-KB in order for the ZDM-KB module to build the Knowledge Base.  The KB is re-built periodically (e.g., every 1 hour) by querying on both the textual and machine/IoT data of RAPpID. ZDM-KB provides a SPARQL query API as well as domain specific API so as to ease the integration of the client of the ZDM-KB component. The ZDM-KBUI is integrated with the ZDM-KB via the ZDM-KB API.
