Fault diagnosis presents a considerable difficulty to human operators in supervisory control of manufacturing systems. Implementing Internet of Things (IoT) technologies in existing manufacturing facilities implies an investment, since it requires upgrading them with sensors, connectivity capabilities, and IoT software platforms. Aligned with the technological vision of Industry 4.0 and based on currently existing information databases in the industry, this work proposes a lower-investment alternative solution for fault diagnosis and problem solving. This paper presents the details of the information and communication models of an application prototype oriented to production. It aims at assisting shop-floor actors during a Manufacturing Problem Solving (MPS) process. It captures and shares knowledge, taking existing Process Failure Mode and Effect Analysis (PFMEA) documents as an initial source of information related to potential manufacturing problems. It uses a Product Lifecycle Management (PLM) system as source of manufacturing context information related to the problems under investigation and integrates Case-Based Reasoning (CBR) technology to provide information about similar manufacturing problems.

Developing and sustaining complex systems requires collaboration of multidisciplinary teams, coordination of processes, methods and tools, allocation of resources and utilization of adequate facilities within enterprises. The system engineering management comprises three intertwined domains: the product, the project and the enterprise. Despite the obvious links between them, each is carried out using its distinct ontology and toolset. This conceptual separation hinders effective handling of the project and product lifecycle activities within the enterprise. Testing activities of complex products are focused on verifying the performance of increasingly large modules, from software and hardware components, through subassemblies to the entire operational system. What needs to be developed, tested, and delivered is determined by the product requirements, its functions, architecture, components, and their interactions. When each component should and can be developed and tested is determined by the project plan, which is dynamically re-estimated, re-evaluated, and re-planned depending on different parameters such as the project actual status compared with the plan, recourses availability, risks, technological breakthroughs or other impacting issues. Whether carrying out the development mission is feasible is determined by the responsible enterprise, its size, structure, management criteria, other projects running in parallel, commitments, and many other aspects. This paper introduces a unified project-product lifecycle management framework that attempts to address the problems cause by separating the product from the project that is supposed to deliver it within the executing enterprise.
