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.

Project: Performance measurements in the semi-process industry

The Information Systems group is often contacted by industrial organizations with assignments that could lead to student projects at various levels (master thesis project, bachelor completion project, etc.) Through this website we make these topics available to our students. In this post, we announce one such project, involving company Marel.

Performance measurements in the semi-process industry

The organization

Marel is an international supplier of advanced systems for the food processing industry. With around 3700 employees worldwide, Marel focuses on the segments of Poultry Processing, Further Processing, Meat and Fish. At its modern plant in Boxmeer, the operating company Marel Stork Poultry Processing B.V. focuses on the design, production and installation of production systems for the poultry processing industry. As the world market leader, the organization is constantly looking for opportunities to increase the productivity of its customers, within the bounds of quality and innovation. In addition to offices in Boxmeer (NL), Dongen (NL) and Gainesville (Georgia, USA), the organization has regional offices in a large number of countries.

Master Thesis assignment

The highly automated production lines of modern poultry processors process 13.500 broilers per hour. Each broiler has its own quality specifications and unique weight, which determines its destination and potential value. The destination of a broiler can end up in several different articles; a modern retail plant offers a variety of more than 500 product articles.  In order to make optimal use of the potential value of each individual broiler an information system is required. A lot of attention is paid to animal welfare, food safety, quality, full traceability, water and energy consumption. The aim is to add value to poultry as effectively as possible. The overall performance of a poultry processor is depending on a lot of factors, one of the indirect factors is production planning. Production planning on a daily level is a real challenge in the poultry processing industry. The uncertainty of the demand on one side and the dynamics of the raw material supply on the other side ask for planning skills of the processor. A lot of data and an information system are used to control the production. The exact impact of planning and scheduling is difficult to determine, but enhancements of the planning performance gains big advantages. Innova is the provided information system by Marel to support planners. For now we have an interesting Master Thesis assignment for an entrepreneurial student. In order to improve the planning performance on the long term, initially the performance should be measured in order to quantify possible improvements. The assignment is to set up a method to measure the production planning performance of a retail poultry processor. The business process of production planning is known and can be used as a starting point. Determining (key) performance indicators and an overview of required vs. redundant (available) data are the most obvious deliverables.

Process Tales

There are many ways to describe processes, even business processes.

And where there is variety, there is dissent. Adherents to one particular modeling paradigm are not holding back in their scorn on the tastes and preferences of other denominations.

At this point, I do not expect a grand unification of opinions to take place anytime soon (although it’s perfectly clear that Petri nets are everyone’s best choice, of course). Perhaps a more productive view on this matter is to accept the co-existence of various modeling paradigms, while trying to understand how they can be used in harmony, either as alternative or complementary representations.

I will give two illustrations of current research that I am conducting with various colleagues that embraces this position: (1) work on hybrid process models, and (2) text-process model comparisons. Since it is also “Sinterklaasavond”, I will keep it short and sweet.

After this talk a drink will take place in the PVOC.
