When a major chemical accident occurs, emergency response is an important measure to reduce accident losses. Some actions in an emergency response may be more important than others in reducing accident losses, so they need to be carried out as a matter of priority. The impact of the number of emergency personnel on the relationship between...

Fire is one of the main accident scenarios occurring in chemical and process plants, and it can lead to domino effects due to thermal radiation. Emergency response is necessary to prevent fire escalation, in addition to safety barriers. In major industrial fire accidents, backup is usually required in emergency response, due to the lack of...

Nowadays, software is an integral part of many companies. However, the codebase can grow large and complicated and is often insufficiently documented. To gain insight, tools have been made to infer state machines and process models from software logs. These tools produce different types of models such as automata and Petri nets. The main...

Emergency response is an important way to reduce losses after a major industrial accident occurs and mitigation measures should be arranged and analyzed in preparedness. The cooperation in emergency response actions which make up an emergency response process has a significant impact on the efficiency and success rate (or reliability) of...

A fire accident is one the most dangerous accidents that may lead to knock-on effects, especially in the plants dealing with large quantities of hazardous substances. Different from other accidents, e.g., explosions, fires can last certain period of time and the thermal radiations emitted by them have a synergistic effect. At the same time, the...

Predictive aircraft maintenance is a complex process, which requires the modeling of the stochastic degradation of aircraft systems, as well as the dynamic interactions between the stakeholders involved. In this paper, we show that the stochastically and dynamically colored Petri nets (SDCPNs) are able to formalize the predictive aircraft...

Aircraft maintenance is key for safe and efficient aircraft operations. While most studies propose cost-efficient maintenance strategies, the safety and efficiency of these strategies need to be quantified. This paper proposes a formal framework to assess the safety and efficiency of maintenance strategies by means of agent-based modelling,...

To identify and improve the communication or information flow for a ship production process, this thesis provides an approach to use a Discrete Event Simulation (DES) model, based on Petri Net technique. By establishing a theoretical framework, the different simulation modelling options are analysed and based on practical requirements, a choice...

In dit onderzoek hebben we een nieuwe dienstregeling voor tramlijn 19 opgesteld. Deze tramlijn rijdt nu tussen Delft en Leidschenhage. In 2020 zal het traject worden uitgebreid met haltes op de campus van de TU Delft. In dit onderzoek hebben we twee dienstregelingen opgesteld: één voor in de spitsuren, en één voor in de daluren. Er zijn een...

: In this thesis Max-Plus Algebra is discussed. This is an algebraic structure which is useful for modelling scheduling problems. Instead of normal addition and multiplication respectively the operations maximum and addition are used. Together with max-plus algebra another modelling method is described: Heaps of Pieces. This looks like Tetris...

During an emergency response to an accident or disaster, emergency response actions often need to use various emergency resources. The use of resources plays an important role in the successful implementation of emergency response, but there may be conflicts in the use of resources for emergency actions. According to the emergency response in...

Reinforcement learning (RL) is a machine learning technique whereby the controller learns the control law by optimizing the received cumulative amount of reward. A reward is an instantaneous evaluation of the applied action at the current state, given by reward function. However in theory the reward function is assumed to be given, in practice...

This thesis describes an architecture for distributed computation in mobile environments. Here, the workflow stands for the operational aspect of a work procedure. This notion subsumes the structure of the tasks, who performs them, what their operation structure is, how they are synchronized, how information flows to support the tasks and how...

Discrete Event Systems are systems, the time evolution of which can be described by the occurence of events. Well-known examples of DESs are manufacturing systems and transportation networks. An important class of DESs can be described by the so-called (max,+) algebra, in which, compared to the usual arithmetic, the operator + is replaced by the...
