In March 2015 I got my Master’s degree in Biomedical Engeneering at the Eindhoven University of Technology (TU/e) in the field of Regenerative Medicine and Tissue Engineering. I also studied at Leiden University where I obtained my Master’s degree in Medicine in 2008. With this background I am able to bridge the gap between technology and patient. It inspires me to combine multiple disciplines and work with experts from different professional backgrounds.Saskia van Loon

Currently, I work as PhD student at the department of Clinical Chemistry and Laboratory Medicine at the Catharina Hospital in Eindhoven. My PhD project is part of the Data Science Flagship, a collaboration between TU/e and Philips Research (IMPULS 2.0). The aim of the project is to improve the outcome of cardiac resynchronization therapy (CRT) using hospital data and/or personal health devices by discriminating beforehand between responders and non-responders of CRT.

Presentation by Dr. Zhengxing Huang: Predictive monitoring of clinical pathways

Dr. Zhengxing Huang of Zhejiang University (Hangzhou, China)

Predictive monitoring of clinical pathways.

Accurate and timely monitoring, as a key aspect of clinical pathway (CP) management, provides crucial information to medical staff and hospital managers for determining the efficient medical service delivered to individual patients, and for promptly handling unusual treatment behaviors in CPs. In many applications, CP monitoring is performed in a reactive manner, e.g., variant treatment events are detected only after they have occurred in CPs. Alternatively, this study systematically presents a learning framework for predictive monitoring of CPs. The proposed framework is composed of both offline analysis and online monitoring phases. In the offline phase, a particular probabilistic topic model, i.e., treatment pattern model (TPM), is generated from electronic medical records to describe essential/critical medical behaviors of CPs. Using TPM-based measures as a descriptive vocabulary, online monitoring of CPs can be provided for ongoing patient-care journeys. Specifically, two typical predictive monitoring services, i.e., unusual treatment event prediction and clinical outcome prediction, are presented to illustrate how the potential of the proposed framework can be exploited to provide online monitoring services from both internal and external perspectives of CPs. Extensive evaluation on a real clinical data-set, typically missing from other work, demonstrates the efficacy and generality of the proposed framework for surveillance-based CP management in a predictive manner.

Presentation by Arthur ter Hofstede: Event Log Imperfection Patterns for Process Mining

Title: Event Log Imperfection Patterns for Process Mining

Presented by Arthur HM ter Hofstede

Based on joint work with Suriadi Suriadi, Rob Andrews and Moe Wynn


An essential component of a process mining exercise is the ability
to properly prepare the log(s) for analysis. This entails detecting various
types of errors and deficiencies as the quality of the analysis heavily
depends on the quality of the event log. Unfortunately this is not a trivial task
and much depends on the skills and experiences of the analyst(s) involved.
In order to more systematically approach log preparation and to
reduce the dependency on specialist skills, a set of patterns is proposed.
These patterns aim to capture the various types of issues that may be encountered,
the way they may manifest themselves, how they may influence analysis results,
and potential remedies to counter these issues.

Development of a functional and technical specification for a new a Marine Vessel communication and planning tool

Project Title: Development of a functional and technical specification for a new a Marine Vessel communication and planning tool.

Opportunity Statement:The Dow Supply Chain function is actively pursuing opportunities to provide the lowest cost to serve whilst meeting best in class levels of quality and reliability. The recently implemented SAP R3 ERP system (ECC) supports different functions in executing and improving their day to day operations and deliveries to its customers.

Dow’s global Marine Deep Sea vessel function, yearly shipping more than 14.000.000 Tons  of chemicals (the equivalent of 600.000 trucks) involving freight expenditures of more than 360 million Dollars, continues to be managed outside ECC. Hence, work process related information is mainly communicated and maintained by means of  Excel spreadsheets, emails and several other standalone tools (example MAPS).

Global Supply Chain leadership envisions to implement a Marine IT solution that would allow Dow to manage Deep Sea marine shipments using one global tool fully or partly integrated with Dow’s new ECC system.

This would improve the efficiency, quality and transparency of the Marine material flow work process, order to cash.

Project Scope & Boundaries:The scope of the project relates to defining the functional requirements on the systems side of the Dow global bulk marine work process integrating with functions which directly depend and/or interact with the process such as planning, site logistics, carriers, documentation, procurement etc. Also in-scope is the jetty/berth scheduling  capability for Dow jetty’s currently managed within MAPS.

Project Goal/Objectives:This charter embodies the project of drafting and defining the functional and technical specification for a Marine IT solution, possible integrated or interfaced with Dow’s ECC system.

The objective is that once Dow’s internal IT function (Diamond Systems Solutions) receives the go-ahead to design and implement a new marine solution, a specification  is available which can serve as base for the final design.

Timeline / Location:
-        4-6 months
-        Preferred start date: Q2 2015 ( but other timing can be discussed)
-        Location: Terneuzen. (local student-housing in Terneuzen will be provided)

Deliverables:The specification should encompass functional requirements, integrating the following process’, with functions between brackets:

  • Vessel planning and shipment initiation (Planning / Scheduling)
  • Vessel nomination and chartering (Marine Operations)
  • Vessel risk and suitability acceptance (Vetting)
  • Nominating and instructing external parties (Marine Operations)
  • Detailed jetty & vessel scheduling, document printing (Dow Site Logistics, Terminals)
  • Direct access to documents, E-Docs, survey reports (Documentation)
  • Unplanned event follow including escalation (Marine Mode)
  • Data collection supporting performance monitoring and demand/capacity validation
  • Spot fixture process (Procurement)
  • Freight/accessorial costs payment & approval process (Accounts Payables)

New Employee Maryam Razavian

Maryam-Photo-NewI got my Ph.D. degree in computer science, in the area of migration to services from VU University Amsterdam. I also was a postdoc for 2 year @VU in Sofware and Service group. My research interests are in design reasoning knowledge management, software architecture, service orientation, and sustainable e-services.

During my PhD, I developed an approach for rehabilitating pre-existing legacy assets by encapsulating them as services that are, simultaneously, value-adding and technically sustainable. Such services, embedding various business functions, are specifically designed to smoothly operate in modern business processes, within networked organizations. This approach, called the Lean & Mean migration approach, was emerged out of existing practice of service migration in various industries.

During my Postdoc, I have investigated the discrepancies between business and technical sustainability of services. In the area of design thinking, I have performed an empirical study on the inuence of reflections on the the way designers of services and processes think. The main finding, simply put, was that such a design is a tricky business influenced by many cognitive factors such as the ability of a designer to reflect or communicate with various stakeholders.

At TU/E I will continue my research  on guiding service designers thinking and reasoning in order to address many of the complexities inherent in service design.

Blueprint design of service dominant enterprise architecture for Canon Business Services

Nowadays services are dominating the economies of the world and are becoming an important part of strategic thinking of business organizations. Services are no longer treated as a separate category for strategic mission and planning but rather an all pervasive part of it. Most of the business organizations today are more or less involved in a combination of providing goods with services.
The transition marked evolution of servitization concept, which is described as how companies initially considered themselves to be in “goods” or “services” (e.g. automobile or insurance), and then moved to offering goods combined with closely related services (e.g. products offered with maintenance, support, finance). This creates service-dominant business markets requiring high levels of agility. Thus, there is a need for a structured way to design business in a service-dominant context.

The project is carried out at the Strategic Business Unit (SBU) based at Océ Technologies in Venlo, Netherlands. The Strategic Business Unit (SBU) which is a part of Canon Business Services (CBS) is focused on developing and growing the business service of value added outsourcing of document processing on a global level together with the Canon Sales Organizations.

Blueprint of the architecture for service innovation in CBS is designed in this project using BASE/X as a reference framework. BASE/X is the acronym for Business Agility through Service Engineering in a Cross-Organizational Setting, which will support the efforts of dealing with the agility of service-dominant business, the complexity of solution-oriented business (value-in-use) and multi-sided business models. BASE/X is based on a structure of stable and flexible layers composing a pyramid (from top to bottom the layers are: Strategy, Business Model, Service Compositions and Business Services).

The design of the conceptual blueprint structures the business aspects of value added outsourcing of document processing services in one framework. With BASE/X as a reference framework and through a number of design steps, it proposes an enterprise standard architecture for CBS which will be a blueprint for the organization of value added outsourcing of document processing services, helping in the composition of new services and consequently supporting the agility in service-dominant business.

The Immaturity of Business Process Maturity Research

Business processes are basic enablers in sustaining an organization’s existence in delivering high-quality products and services. Business process maturity models (BPMMs) can act as an instrument to assess and continually improve business processes. A maturity model incorporates a conceptualization of discrete maturity levels and corresponding best practices for a set of processes in a specific domain. In the last decade, researchers and practitioners have proposed several BPMMs with varied focus and depth. Yet, a recent systematic review of the literature indicated that the use of maturity models has not gained widespread acceptance in the Business Process Management field. Underlying challenges include the scarcity of empirical works confirming the validity and usefulness of the models, limited extent of prescriptive properties of the models impeding their application, and the lack of a clear distinction between the maturity model and the assessment model. This talk, therefore, aims to overview the state of research regarding BPMMs and their effect on business performance, to summarize our ongoing work in the healthcare domain, and to propose an agenda for the future research on this topic.
