Strategies for the set-up of a multi-Process Landscape evolution model.
2020Co-Authors: Arnaud J. A. M. Temme, Jeroen M. Schoorl, Lieven ClaessensAbstract:Landscape evolution models have become geomorphology’s virtual laboratories, in which wide ranges of assumptions and conditions can be simulated over large spatial and temporal scales. The larger the spatial and temporal scale, the larger the probability that Landscape evolution is a result of multiple, interacting Processes. Building a Landscape evolution model that combines these multiple geomorphic Process requires special attention for the formulation and interaction between these Processes. This contribution focuses on this formulation and presents strategies and model tests that can be used to inform model setup decisions. A first decision in the setup of multi-Process Landscape evolution models concerns the number of Processes to be included. We argue that the relevance of individual Processes is not merely a function of the volume of material involved in that Process, but also a function of the effect the Process has on the activity of other Processes. For instance, the volume of material involved in landsliding may be very small relative to the volume of material involved in water erosion and deposition, but if that small volume blocks river valleys, it would still be important in Landscape evolution. A strategy to inform this decision with model tests is presented. Following up on the blocking of river-valleys through landslides, prospective Landscape evolution modellers must decide whether interaction between geomorphic Processes occurs through the presence of sinks. In our example, it clearly does ‐ meaning that the Landscape evolution model must be equipped to deal with sinks instead of proclaiming them errors that must be removed as soon as they occur. Similar reasoning could be applicable to many areas in the world, including post-glacial hummocky plains, karst Landscapes and tectonically active mountain ranges. Thirdly, a decision must be made about the temporal resolution at which every Process operates. We present a model test to inform this decision that uses observations of Landscape evolution ‐ such as river terrace sequences, or a buried palaeo-surface. Temporal resolution of individual Processes is varied, while keeping resolution of other Processes constant. Effects on model performance are monitored, and the lowest temporal resolution that leads to acceptable model performance is selected. In these strategies, the explicit consideration of uncertainty effects on the resulting setup decisions is advocated. As we will show, Monte-Carlo technology provides a simple toolbox that allows this consideration.

evaluating choices in multi Process Landscape evolution models
Geomorphology, 2011Co-Authors: A J A M Temme, Lieven Claessens, A Veldkamp, Jeroen M. SchoorlAbstract:The interest in Landscape evolution models (LEMs) that simulate multiple Landscape Processes is growing. However, modelling multiple Processes constitutes a new starting point for which some aspects of the set up of LEMs must be re-evaluated. The objective of this paper is to demonstrate the practical significance of, and possibilities for such re-evaluation. We first discuss which simplifications must be made to set up LEMs. Then, simplifications of particular interest to the modelling of multiple Processes are identified. Finally, case studies from New Zealand, Belgium and Croatia explore the performance of different model versions under several common choices for model and data simplifications. In these case studies we illustrate methods to make the choices, typically by i) comparing the results of different model versions, ii) assessing model validity or iii) indicating the sensitivity of models for different simplifications. The results indicate that LEM performance is strongly dependent on multi-Process related choices, and that performance indicators can be used for ex-post testing of the influence of these choices. In particular, we demonstrate the significance of simplifications regarding the number of Processes, presence of sinks and temporal resolution.

linking land use and Landscape Process modelling a case study for the alora region south spain
Agriculture Ecosystems & Environment, 2001Co-Authors: Jeroen M. Schoorl, A VeldkampAbstract:Changing land use is increasingly known to affect on-site Landscape properties, nevertheless off-site effects are often neglected. A single Process Landscape evolution model (Landscape Process modelling at mUlti dimensions and scaleS (LAPSUS)) is used to explore the impacts of land use changes on Landscape and soil properties. Examples are shown for both on-site as well as off-site effects of land use change and the influence of different pathways of change. A case study area near Alora, in the province of Malaga, south Spain is selected. In this area the main land use consists of citrus, olive/almond, wheat, semi-natural vegetation and a rest group (bare, river beds, urban). For a period of 10 years LAPSUS calculates soil redistribution (erosion and sedimentation) for different scenarios of input parameters. These inputs are a digital elevation model (e.g. slope lengths and angles), precipitation, soil erodibility, and land use related infiltration. For each scenario, different assumptions are made on direction and rate of land use change. As an example, effects of abandonment of olive orchards are demonstrated, simulating both a fast and gradual change for a period of 10 years. Each scenario produces different spatial and temporal patterns of total amounts of erosion and sedimentation throughout the Landscape. As a result, potential land use related parameters like soil depth, infiltration and flooding risk change significantly too. The scenario of an abrupt change produces the highest erosion rates compared to the gradual change scenario and the baseline scenario. However, because of the multi-dimensional characteristics of the Landscape, not only the area suffering from land use changes is affected. Increasing erosion and run-off rates from upstream-located olive orchards have an impact on down slope local run-on, erosion and sedimentation rates. In this case, the citrus orchards situated in the valley bottom locally suffer damages from re-sedimentation events but benefit from the increase in run-on water and nutrients. Concluding, off-site effects from an exogenous driven change in land use (EC subsidies) can trigger endogenous land use changes in adjacent areas.

AMCIS - Business Process Model-based Evaluation of ICT Investments in Public Administrations
2008Co-Authors: Jörg Becker, Philipp Bergener, Stefan Kleist, Daniel Pfeiffer, Michael RäckersAbstract:This paper presents an approach to asses ICT investments in public administrations. The public sector bears great potential for business Process optimization through ICT. However, these possibilities remain largely unexploited since the effects of ICT on the Processes are not clear to decisions makers. To asses this impact all Processes of a public administration, the Process Landscape, have to be taken into account. The PICTURE modeling method has been proposed as a way to efficiently model the whole Process Landscape. Based on the knowledge captured with those Process models, the impact of certain ICT functionalities on the Processes can be analyzed. ICT investment decisions become more transparent towards the political leadership. This paper has two research objectives: First, an architecture for an automated evaluation of ICT investment decisions is introduced. Second, the practical feasibility of the architecture is shown based on an investment decision for a document management system.

Lecture Notes in Computer Science, 2008Co-Authors: Jörg Becker, Philipp Bergener, Stefan Kleist, Daniel Pfeiffer, Michael RäckersAbstract:Within the public sector domain there is great potential for business Process optimization through ICT. However, until today these possibilities remain largely unexploited. To measure the impact of ICT-investments all Processes of a public administration have to be taken into account. The PICTURE modelling method has been proposed as a way to efficiently model the whole Process Landscape of a public administration. Based on the Processes captured, the impact of certain ICT functionalities can be analyzed. ICT investment decisions become more transparent towards the political leadership which are the decision makers in the public sector. This paper has two research objectives: First, an architecture for an semi-automated evaluation of ICT investment decisions is introduced.

domain specific Process modelling in public administrations the picture approach
Electronic Government, 2007Co-Authors: Jörg Becker, Daniel Pfeiffer, Michael RäckersAbstract:In this paper a domain specific Process modelling method for public administrations is presented. The public sector is facing an increased service level demand from citizens and companies which comes along with reduced financial scope. Higher Process efficiency as well as time and cost savings are required to cope with this challenge. However, reorganisation projects in public administrations with established generic Process modelling methods could only identify limited reorganisation potential and just led to small local improvements [1]. Therefore, we have created the domain specific modelling approach PICTURE. The PICTURE-method applies the domain vocabulary to efficiently capture the Process Landscape of a public organisation. Thus, PICTURE creates Process transparency and is able to detect holistic reorganisation potentials within the entire administration.

Bausteinbasierte Modellierung von Prozesslandschaften mit der PICTURE-Methode am Beispiel der Universitätsverwaltung Münster
WIRTSCHAFTSINFORMATIK, 2007Co-Authors: Jörg Becker, Daniel Pfeiffer, Lars Algermissen, Michael RäckersAbstract:Public administrations face a strong pressure to reorganise caused by decreasing financial resources, a changing political environment, and increased customer demand. A Process oriented visualisation, analysis and improvement of administrational Processes is a key prerequisite for the successful organisational and technical change of public administrations within the current reorganisation activities. In order to successfully conduct reorganisation projects a coherent view on all administrational Processes (the Process Landscape) and their interdependencies is of great value as a starting point. Common approaches to collect and visualise Processes lead to such complex models that only a small percentage of the overall Process Landscape can be examined. The PICTURE-method as the core of this paper surpasses weaknesses of classical approaches and allows for a very efficient means of modelling the Process Landscape by using 24 domain specific reusable Process building blocks. Hence by applying the PICTURE-method one can create a high degree of transparency as a base for reorganisation projects. In this paper we conceptually introduce the PICTURE-method and describe its practical application in a large modelling project within the administration of the University of Münster. We describe the experiences made by applying PICTURE and evaluate the method in terms of the requirements made by the project contractor. Die Prozesslandschaft als Menge aller in einer Organisation ausgeführten Geschäftsprozesse ist das neue Handlungsfeld der Prozessgestaltung in öffentlichen Verwaltungen. Zur Modellierung und Analyse einer Prozesslandschaft ist ein neuer methodischer Ansatz erforderlich: Die PICTURE-Methode dient zur modellierung der Prozesslandschaft. Sie besteht aus 24 domänenspezifischen Prozessbausteinen mit festem Abstraktionsniveau, die durch Attribute näher spezifiziert und zu einzelnen Prozessen zusammengesetzt werden können. Mit der PICTURE-Methode lässt sich die Prozesslandschaft deutlich effizienter modellieren, als dies klassische Modellierungsmethoden leisten können. Die PICTURE-Methode wurde im Praxiseinsatz in einem Modellierungsprojekt der Universität Münster evaluiert und hat die an sie gestellten Anforderungen erfüllt.

Business Process Modeling on the Basis of Semantic Standardization
2020Co-Authors: Jörg Becker, Nico Clever, Justus Holler, Maria ShitkovaAbstract:Within this article the prototype icebricks is described by its main characteristics which are layers of abstraction, attribution, reference models and semantic standardization by the use of a glossary. The layers are predefined in order to enhance the clarity and comparability of the Processes. Attribution is used - beside the layers of abstraction - as means to reduce the complexity of the models by shifting information to analyzable and easily maintainable attrib- utes instead of sophisticated control flows within the Process elements. The glossary is inspired by the idea of model conventions. Each business object within it is defined once and can be used with defined activities as Process building blocks within all models with the same semantic meaning. Further- more, reference models are incorporated into the prototype to enable modelers with the possibility to create or derive purposeful models in a short period of time. The prototype was thoroughly and very successfully evaluated in its web based version in two Process modeling projects aiming for Process reorganiza- tion for an ERP system change and for a complete documentation of the Process Landscape for knowledge management.

Business Process Management Cases - Business Process Management in the Manufacturing Industry: ERP Replacement and ISO 9001 Recertification Supported by the icebricks Method
Business Process Management Cases, 2017Co-Authors: Jörg Becker, Nico Clever, Justus Holler, Maria NeumannAbstract:(a) Situation faced: A family-owned manufacturing company recently went through the transfer of management from the older to the younger family generation. A number of problems were uncovered during this Process, such as prevalence of tacit knowledge, an inefficient decision-making Process, outdated IT system support, and an urgent need for certification of production Processes according to quality-assurance standards (ISO 9001). Each of these problems required thorough documentation of the as-is business Processes in the organization to guide their improvement. (b) Action taken: To ensure that the created Process models serve as a valid communication medium, the company’s Process Landscape was created during an initial workshop between the executives and external BPM consultants. Then the information on Processes in the company’s various departments was gleaned from semi-structured interviews with the department employees. At the same time, Process weaknesses and potential improvements were derived and discussed with the functions’ management. The succeeding depiction of the to-be Process framework was achieved with the help of the icebricks modeling method and the corresponding software tool, which is a lightweight, standardized approach to ensure high quality of Process models. (c) Results achieved: During the modeling phase of the project, external BPM consultants documented the Process Landscape, thereby explicating the company’s knowledge and good-practice Processes. The Process Landscape served as basis for well-informed decisions regarding the implementation options of a new ERP system, which was introduced on time and on budget in the second phase of the project. The ISO 9001 recertification of production Processes was achieved in the third project phase with the help of the Process documentation that had been created. (d) Lessons learned: Simply deploying Process models on the company’s intranet platform does not necessarily lead to their desired comprehension and use. All employees have to be trained that Process models are a means of communication and are never finalized, a notion that also applies to continuous Process improvement. Process owners must be defined so they take responsibility for adjustments to the Process environment beyond the project’s lifecycle, but such responsibility is not solely that of a project manager. Furthermore, the project demonstrated the appropriateness of the icebricks modeling method for the manufacturing domain, although it was originally designed for the retail industry.

PACIS - Model Based Identification and Measurement of Reorganization Potential in Public Administrations – the PICTURE-Approach
2008Co-Authors: Jörg Becker, Daniel Pfeiffer, Lars Algermissen, Thorsten Falk, Philippe FuchsAbstract:Public administrations are faced with a modernization and performance gap. On the one hand citizens and companies have increasing requirements. On the other hand the financial and human resources remain static or even decrease. In recent years public administrations tried to counteract with reengineering their business Processes. However, it is observable that reengineering projects in public administrations have a too narrow focus as they concentrate on a small subset of their overall Processes. In this paper we claim that significant progress in the identification and measurement of reorganization potential can only be achieved by including the majority of all administrational Processes – the Process Landscape. Therefore, we propose a method architecture which is capable of two things: Firstly, it supports a distributed modeling Process across a whole public administration in order to capture the Process Landscape. Secondly, it is able to estimate the reorganization potential within the Process Landscape based on an analysis model. A working example derived from a currently funded EU project is supplemented in order to demonstrate our approach and to make it more comprehensible to the reader.
