Improving the patient order flow in the preparation process of a radiotherapy outpatient clinic
A case study performed at Amsterdam UMC - Location VUmc
The preparation process is a complex process: Many different process steps are necessary to prepare the radiotherapy of a patient. Due to the presence of a waiting queue before each of the process steps, the flow is restricted and errors occur in the corresponding information flow. Often, the reason is the limited insight in the other process step. No overarching control is available to control the flow between the different sections. Interventions occur, but does not rely on organized control structure. The available control is only taking into account the own process step.
The fact that the radiotherapy department is too much functionally organised is the main reason for the existence of these problems. The functional design is a requirement for the radiotherapy system. However, within the outline of the functional design, improvements are possible. These improvements have to create an improved flow of patients with a transparent and coordinated execution.
The main solution for the problem is the design of control structure based on the matrix organisation theory. The functional control structure remains and a patient order control structure is designed. The functional control structure is elaborated by the measure of the length of the waiting queue of the previous process step. The patient order control structure controls the flow of the patient orders throughout the preparation process. This control is executed on the basis of the date of the start of the radiotherapy treatment. The start of the radiotherapy treatment is the end of the preparation process. This date is determined earlier in the process and the different process step due times will be adapted according to that date. \newline
The solution is able to improve the transparency in the department. The patient order progress is monitored during the preparation process and the different process steps will have more insight in the upcoming flow. Especially the patient order control structure is able to coordinate the flow based on the determining of the date of the start of the treatment in an earlier phase.
For the examination of the effect of the proposed patient order control structure, a simulation model is built. The simulation model shows the positive effect on the flow of the patient orders through the department: The variation in the waiting queue length is reduced, the variation in the process time is reduced and the variation in the number of patients who will start their treatment on a certain day is reduced. ...

Coordinating supply and demand in Haga hospital outpatient planning
Towards a more service-oriented control structure
In this dissertation three issues have been identified concerning today’s creation of systems:
•Imperfections in the creation process of both systems and the project teams that create the system,
•Lack of reflection,
•Lack of semantic ability.
The objective of this dissertation is to provide a framework in which the backgrounds of these three issues are expressed and offer a way to overcome these issues. The framework can be utilized by enterprises to improve interoperability and symbiosis in the field of Systems Engineering enabling them to improve performance of projects in all lifecycle stages of a system.
The framework addresses interoperability barriers and integrates Systems Engineering principles, organization science, system science, complexity science and cognitive science. The framework has been visualized by means of six symmetrically connected tetrahedrons, supported by an ontology. Additional terms of reference has been drawn up for the purpose of implementation of the framework. A prototype of a collaboration tool based on a specific semantic WEB technology as published in several papers by the author, supporting the framework, was part of the work done for this dissertation. The framework is based on years of experiences of author with complex projects and knowledge as captured in ISO standards and fundamental theories. ...

An impact analysis of bypassing the Heineken distribution center in Germanyan impact analysis of bypassing the Heineken distribution center in Germany
NIBC has a wide portfolio of vessels which will have to comply with the IMO BWM convention. However, the possible solutions and the actual impact of this regulation is still unknown to the bank. Ship owners expect a significant impact on the shipping industry and it is suggested that a lot of vessels will have to be scrapped due to the high investment cost.
This research is conducted for ship owners and banks and will reveal the actual impact of the BWM convention. This is realised by calculating the impact on the internal rate of return (IRR) for each specific vessel. It provides the bank with a tool to monitor what effect the BWM convention will have on their clients. In addition, the tool is able to identify high risk vessels with an internal rate of return below 9%. ...

enables the operators to schedule the task of loading of containers by supplying real-time information from packaging. A simulation test the effect of the proposed solution. Concluding that the proposed overview has a positive effect on the performance of the system. However it also identifies hurdles in creating the overview in practise, as the needed information is not present
