The RIS provide the mechanisms for access and retrieval of distributed product information. In order to identify information that is related to a specific product, product ID resolution is required. In order to protect any intellectual property that is associated with the product data, access control to the product data is required. Accordingly, the three main concepts under the RIS pillar are:
Search & Retrieval: For PREMANUS information related to the lifecycle of a product needs to be collected from different business systems and also from diagnostics processes (such as predictive maintenance and monitoring systems). This information is required by the BDSS system. One part of the RIS is the Distributed Product Information Search & storage (DPIS) service; it enables the search and retrieval of product information along a product’s lifecycle across its ecosystem. The DPIS is accessed by the BDSS through a product data query and modification interface (PDQMI). Modification refers to the ability to retrieve data from many different information systems in many different formats and data models and import it into a storage system in a unified schema for product data. The unified schema PREMANUS uses is the Quantum Lifecycle Management (QLM) standard.
Product ID matching and resolution: In order to find out product information and its service history, it is important that the system provides the ability to reference products by their unique identifiers. The concept of “Object Name Service” (ONS) in the EPC global standard, which provides business applications with information related to Electronic Product Codes (EPC), is used by many manufacturers for ID resolution [EPCIS]. However, the specific challenge for remanufacturing is that although every product ID is unique and relevant to the OEM who has produced it, the ID may not be resolvable by other stakeholders in the manufacturing ecosystem (such as remanufacturing specialized subcontracted SMEs as below). Also the PREMANUS RIS service must be applicable to any other product ID scheme applied by manufacturers and service providers along a product’s lifecycle.
Role-based access control: The PREMANUS software solution presents a unique challenge in the sense that different stakeholders with varying business interests and hierarchy, request access to product data to accomplish various EoL product recovery phases. Thus, OEMs would like to protect sensitive product related information from third party subcontract remanufacturers who may only be authorized for limited access of product information. This component within the RIS will enforce access control polices defined by the information owner.
As this is a complex and wide area, PREMANUS contributes to the standardization efforts within the QLM standard by providing requirements and concepts.
