Towards integrated digital twins for construction and manufacturing

A digital twin (DT) can enhance construction management with comprehensive real-time simulations. However, research rarely considers prefabrication factories, whose processes have a significant impact on cost and duration. It remains unclear how construction DTs can achieve their expected benefits without dynamically interacting with the DTs of...

GridPenguin: A District Heating Network Simulator

District heating system (DHS) optimization is becoming an increasingly important problem because of the unused potential in flexibility that could allow less energy being wasted and the integration of renewable energy. While new optimization methods are proposed every year to tackle this problem, the literature lacks a good way to benchmark...

An Empirical Estimation on the Impact of Freight Traffic on the Capacity Drop

In recent years, the amount of traffic on the highways has increased continuously and in particular freight traffic. Despite solutions to maximize roadway capacity, the drop of capacity after congestions sets in, remains an active field of study. The influence of freight traffic on traffic flow has received little attention, especially regarding...

The Craft Beer Game and the Value of Information Sharing

The craft beer supply chain in the USA differs from the supply chain of macro breweries in its structure, handled volumes and product shelf-life. In this work, we study how these smaller craft breweries can benefit from transparency in their supply chain. We consider additional information sharing of orders and inventories at downstream nodes...

Planning of production Applied approach for reducing planning nervousness and increasing flexibility

Several different kinds of Miracoli Dinner kits are produced on Line 4 in Oud-Beijerland. The current method of planning of production is not sufficient in terms of product availability and planning nervousness. A new method of Most-Urgent-First planning is proposed and a simulation is run to measure the performance in order to see if another...

Simulation of Product Performance Based on Real Product-Usage Information: First Results of Practical Application to Domestic Refrigerators

Today’s connected products increasingly allow us to collect and analyze information on how they are actually used. An engineering activity where usage data can prove particularly useful, and be converted to actionable engineering knowledge, is simulation: user behavior is often hard to model, and collected data representing real user...
