With the rise of data analytics use in government, government organizations are starting to explore the possibilities of using business data to create further public value. This process, however, is far from straightforward: key questions that governments need to address relate to the quality of this external data and the value it brings. In the...

Ontology alignment is an important and inescapable problem for the interconnections of two ontologies stating the same concepts. Ontology alignment evaluation initiative (OAEI) has been taken place for more than a decade to monitor and help the progress of the field and to compare systematically existing alignment systems. As of 2018, the...

Improved situational awareness, also known as Supply Chain Visibility, contributes to better decisions with the ability to synchronize processes and reduce costs. It requires data sharing of for instance positions, speed, direction, and estimated time of arrival and—departure at locations of vessels, trucks, barges, and trains. Any two...

Ontology alignment is a fundamental task to reconcile the heterogeneity among various information systems using distinct information sources. The evolutionary algorithms (EAs) have been already considered as the primary strategy to develop an ontology alignment system. However, such systems have two significant drawbacks: they either need a...

Each manufacturer, supplier, and retailer has its own chain of collaborating stakeholders to meet their customer demands. Many perspectives can be taken like food safety, security, and sustainability, which may each lead to separate solutions that are not necessarily interoperable with each other. Data can only be shared within the context of...

Data sharing is important to optimize and manage logistics chains. Open standards have been developed and implemented by various logistics stakeholders. These implementations have led to closed solutions with barriers to change and implement innovative concepts like synchromodality. This paper analyzes the implementation of open standards by...

Improved situational awareness, also known as supply chain visibility, contributes to better decisions with the ability to synchronize processes and reduce costs. It requires data sharing of for instance positions and Estimated Time of Arrival (ETA) of transport means. Blockchain technology could be a means to support data sharing, due to its...

Blockchain technology in the last 3–4 years has attracted a great deal of attention due to its potential for the disruption various sectors of the economy including the financial sector, and more recently the mobility and logistics domain. The technology, which was developed as the foundation for the cryptocurrency Bitcoin, has developed much...

In support of the trend towards ever more complex supply chain collaboration for the Physical Internet, a trusted, multi-tenant (and interoperable) data sharing infrastructure has to be enabled. Trust is a condition sine qua non organizations may not be prepared to share potentially competitive sensitive information. As such, trust has to be an...

Blockchain technology receives a lot of interest and investments the last three years. It promises a trusted environment for (un)permissioned data sharing. With respect to logistics, enterprises and authorities can (near) real time share state information. Whenever a stakeholder changes the state of one or more objects like discharging a...

Simulated annealing-based ontology matching [1], or SANOM, is an ontology alignment system which ex-ploits the well-known simulated annealing to find the correspondences. The system considers three differ-ent similarity measures, namely string-based, linguistic-based and structural-based measures. A rudimen-tary version of the proposed method is...

Supply visibility is a prerequisite for increased capacity utilization, avoiding unnecessary bottlenecks, supply chain resilience, and compliance. Capacity utilization is both on the level of transport means such as trucks, trains, and barges, as well the optimal usage of the underlying infrastructure. Hubs like terminals, railway stations,...

This paper proposes statistical approaches to test if the difference between two ontology matchers is real. Specifically, the performances of the matchers over multiple data sets are obtained and based on their performances, the conclusion can be drawn whether one method is better than one another or not. To do so, the paired t-test and Wilcoxon...

Supply - and logistics innovations require data of different, heterogeneous sources. Supply chain resilience for instance requires visibility of goods flows and data of planned infrastructure maintenance and unforeseen accidents or incidents that may cause delays. Technically, there are different ways to share this data, e.g. the messaging...

To meet the challenges for more sustainable, effective and efficient transport services in global logistics, a new IT-paradigm is needed to harvest the opportunities that capabilities for situation awareness and real-time chain composition provide. The iCargo project provides such an advanced, highly distributed, IT infrastructure with, as...

As big data is expected to contribute largely to economic growth, scalability of solutions becomes apparent for deployment by organisations. It requires automatic collection and processing of large, heterogeneous data sets of a variety of resources, dealing with various aspects like improving quality, fusion and linking data sets to provide...

Interoperability in logistics is a prerequisite for realizing data pipelines and the Physical Internet. Forecasting data, real time data, and actual positions of shipments, containers, and transport means shared via events have to be harmonized and are expected to improve all types of processes, support synchromodal planning, and improve risk...
