Today’s largest and fastest growing companies’ assets are no longer physical, but rather digital (software, algorithms...). This is all the more true in the manufacturing, and particularly in the maintenance sector where quality of enterprise maintenance services are closely linked to the quality of maintenance data reporting procedures. If quality of the reported data is too low, it can results in wrong decision-making and loss of money. Furthermore, various maintenance experts are involved and directly concerned about the quality of enterprises’ daily maintenance data reporting (e.g., maintenance planners, plant managers...), each one having specific needs and responsibilities. To address this Multi-Criteria Decision Making (MCDM) problem, and since data quality is hardly considered in existing expert maintenance systems, this paper develops a Maintenance Reporting Quality Assessment (MRQA) dashboard that enables any company stakeholder to easily – and in real-time – assess/rank company branch offices in terms of maintenance reporting quality. From a theoretical standpoint, AHP is used to integrate various data quality dimensions as well as expert preferences. A use case describes how the proposed MRQA dashboard is being used by a Finnish multinational equipment manufacturer to assess and enhance reporting practices in a specific or a group of branch offices.

During recent years, more and more Open Data becomes available and used as part of the Open Data movement. However, there are reported issues with the quality of the metadata in data portals and the data itself. This is a seri- ous risk that could disrupt the Open Data project, as well as e-government initiatives since the data quality needs to be managed to guarantee the reliability of e-government to the public. First quality assessment frameworks emerge to eval- uate the quality for a given dataset or portal along various dimensions (e.g., information completeness). Nonetheless, a common problem with such frameworks is to provide mean- ingful ranking mechanisms that are able to integrate sev- eral quality dimensions and user preferences (e.g., a portal provider is likely to have different quality preferences than a portal consumer). To address this multi-criteria decision making problem, our research work applies AHP (Analytic Hierarchy Process), which compares 146 active Open Data portals across 44 countries, powered by the CKAN software.

In traditional product companies, creating value meant identifying enduring customer needs and manufacturing well-engineered solutions. Two hundred and fifty years after the start of the Industrial Revolution, this pattern of activity plays out every day in a connected world where products are no longer one-and-done. Making money is not anymore limited to physical product sales; other downstream revenue streams become possible (e.g., service-based information, Apps). Nonetheless, it is still challenging to stimulate the IoT market by enabling IoT stakeholders (from organizations to an individual persons) to make money out of the information that surrounds them. Generally speaking, there is a lack of micro-billing frameworks and platforms that enable IoT stakeholders to publish/discover, and potentially sell/buy relevant and useful IoT information items. This paper discusses important aspects that need to be considered when investigating and developing such a framework/platform. A high-level requirement analysis is then carried out to identify key technological and scientific building blocks for laying the foundation of an innovative micro-billing framework named IoTBnB (IoT puBlication aNd Billing).

The Industrial Internet should provide means to create ad hoc and loosely coupled information flows between objects, users, services, and business domain systems. However, today’s technologies and products often feed ‘vertical silos’ (e.g., vertical/siloed apps), which inevitably result in multiple and non-interoperable systems. Standardization will play an ever-increasing part in enabling information to flow between such vertically-oriented closed systems. This paper presents recent IoT messaging standards, notably O-MI (Open Messaging Interface) and O-DF (Open Data Format), whose initial requirements were defined for enhanced collaboration and interoperability in product lifecycle management. A first analytical model of the minimal traffic load (in bytes) to fulfil the required/basic standard specifications is then proposed. A smart maintenance use case relying on the first version of the standard reference implementation is developed, based on which our analytical model is applied to evaluate the degree of deviation (w.r.t. the standard specifications) of this reference implementation.
