The parcel transport industry utilizes automated parcel sorting systems to effectively manage incoming parcels. These systems typically comprise multiple infeed conveyors that converge onto a single merge conveyor for parcel merging. However, the conventional First-Come-First-Serve merging method results in reduced utilization of the merge...

The demand for accurate and effective cool chains has been expected to increase, especially for pharmaceuticals in the air freight industry. However, several problems and challenges remain such as cool chain breaks and cool storage capacity constraints while there are rarely routine systems in place for consistent insight into the operational...

Automation in tomato greenhouses is lacking compared with some other crops. The efficiency and consistency of greenhouse operations can be boosted by implementing automation. Therefore, a new concept that facilitates the robotisation of crop-handling tasks is investigated. This concept combines the existing technology of a movable-gutter system...

Bulk handling grabs are often used for unloading bulk materials such as iron ore and coal from bulk carrying ships. To improve and compare virtual simulations of new grabs, accurate real life kinematic data of grabs is required. Moreover kinematic data can potentially provide insight in current use of grabs, which can be interesting information...

Container traffic worldwide has shown a growing trend during the last years. Also, the number of containers handled per call has increased for many terminals. This poses challenges to existing terminals for more efficient operations and higher productivity. Automation is a way some terminals have tried to achieve this. Most existing automated...

In this thesis, a simulation cost model is presented that can be used to assess the cost-effectiveness of a selection of PdM programs. The proposed model combines a discrete event simulation (DES) model with a cost model. It is specifically designed to analyse the PdM programs for the vacuum compressor pumps at Duyvis. All the PdM programs...

Due to the short shelf-life of flowers (circa 7 days) good inventory management is required to minimize disposals. The trade-off between supplying enough to meet demand yet not too much to prevent expiration is a delicate matter. However, in the current situation uncertainty about inventory levels due to inadequate information and conventional...

Although e-groceries is nothing new, the scale at which it is currently growing in the Netherlands has not been seen before. Over the past four years, the market share of online grocery shopping showed an average growth of over 20% per year. While it was already challenging to keep up with this high demand, it became increasingly more difficult...

This report presents insights in the feasibility of large-scale multi-AGV based parcel sortation systems. A simulation model is created to look at the influence of different aspects of such an Automated Guided Vehicles system. The model uses several design parameters and KPIs to determine the level of influence. Important aspects of this...

In recent years, technologies such as artificial intelligence have enabled computer systems to provide decision support for maintenance planning. Using advanced analytics to determine optimal maintenance actions and moments is called prescriptive maintenance. Multiple prescriptive maintenance models have been proposed for different industries....

In this day and age, failure of railway switches is managed using preventive and corrective maintenance, not predictive maintenance. These maintenance methods may allow for failure, where such a feailure could have been predicted. To combat this issue, this paper proposes a real-time predictive maintenance framework, which can identify the...

Current yard crane models used for studies on various logistic processes in container terminals involving automated yard cranes do not take automation systems into account. The operational container handling performance of automated yard cranes are therefore inaccurately predicted by current models. To avoid logistical problems and financial...

Allseas’ Jacket Lift System (JLS) is a system which is currently being developed and capable of transporting, installing and removing a jacket of a production platform as a whole. As the Block Handling System (BHS), responsible of maintaining tension in the main hoist wires by providing a constant tension (CT) counter force, is preferably...

Currently, Tata Steel IJmuiden is developing a new ironmaking process, called HIsarna. This technique will result in a significant reduction of carbon emissions, allow for more flexible input requirements for materials, and lead to a reduction of processing costs as well. In 2010, Tata Steel IJmuiden built a pilot plant to test and develop the...

The retail market is changing rapidly. Many new offline, as well as online competitors, arrived. As a result, customers became more demanding. One of the critical elements is that customers expect a high variety of products that are always available. Out of Stocks (OoSs) in apparel stores result in lost sales in the short term and a declining...

This research presents a method that can be used to prevent shortages of available trolleys in the floriculture supply chain. There should always be a sufficient number of trolleys available at all floriculture auction locations. However, in the current system, there are problems with availability of the trolleys and the trolleys movements are...

In Rose cultivation companies in the Netherlands, there is a demand for a higher sorting capacity on the existing sorting systems. The objective for this research is to advice which part of the sorting system needs to be adjusted to gain a higher sorting capacity. For the current sorting systems, five bottlenecks are defined, the bottlenecks...
