This diploma thesis deals with the usage of agents in business process modelling. The aim is to identify possible uses in the problem area and to evaluate their potential. Intended usage is analysed on the basis of the objectives of process modelling. Described in detail, it focuses on potential application of agents in a process modelling itself, in deploying executable and flexible processes, process improvements and finally in dynamic planning. A further objective is to provide an overview of current research and literature in problem area. To fulfil the goal available literature is analysed and basis approaches are demonstrated in case study. Paper does not address the implementation of multi-agent systems (MAS). Following introduction reader is guided though basic elements of the processes and their modelling, concept of agents and modelling of MAS. As a process modelling notation BPMN in planned 2.0 release was selected. Next section is devoted to the usage of agents. The last part of the work is a case study discussing the possibilities of agents application in company operating public car auctions. In addition the process model (BPMN) transformation to agent model is presented and further developed as a interconnection between process modelling and agent-based systems. Combination of agent approach with business rules and hybrid simulation are proposed as the most promising usages.

This paper introduces the Mobile Process Landscaping (MPL) method for modelling, analysing and improving mobile business processes. Current approaches for process modelling and analysis do not explicitly allow the consideration of typical mobility issues, e.g. location-dependent activities, mobile networks as resources and specifics of mobile information systems. Thus, our method focuses on the modelling and analysis of these characteristics, and is furthermore based on the process landscaping approach, supporting the easy creation of hierarchical models of distributed processes. The method comes with a specialized modelling notation and guidelines for the creation of process landscapes, context models, and business object models. Furthermore, it provides a catalogue of formally defined evaluation objectives, targeting at typical mobility issues. Each evaluation objective can automatically be tested on the created process landscape. Furthermore, the method includes a best practices catalogue with patterns for process and application improvements for typical mobility situations. A validation of the method is presented showing results from the method’s use in a real-world project.

Process patterns allow the modular modelling and adaptable application of software processes. Present descriptions of process patterns show defects like non-uniform and unequivocal description forms and missing relationship definitions. These defects disadvantageously affect the effective usage of process patterns. In this work we present the language PROPEL (Process Pattern Description Language), which provides concepts for the semiformal description of process patterns and relationships between process patterns. With the help of PROPEL single process patterns can be modelled and, by definition of relationships, be composed to more complex processes. With the representation of different views of a process pattern catalog the process patterns and their relationships can be shown clearly. An example illustrates how a process pattern catalog and the contained process patterns are modelled. It is shown that in applying PROPEL the complexity of a process model can be reduced, the inconsistencies of processes can be eliminated and the flexibility of processes can be improved.

With the desire for conventional coal-fired power plants to perform flexible operations, the impact of this operation has become important to the field of steam turbine modelling. This study sought to develop a computationally inexpensive turbine model with minimal OEM intervention in order to predict the internal clearances of high-pressure and intermediate-pressure turbines from Eskom's current turbine fleet. The study saw the utilisation of the Nozzle Analogy theory to develop a 1D multistage turbine thermofluid model as well as the development of a representative 1D turbine process model in order to predict the internal temperature gradients promoted within a steam turbine during transient operation. From this model a further 3D FEA turbine model of both the HP and IP turbine units were developed from simple turbine diagrams to apply the predicted temperature boundaries and predict the thermal and structural response of turbine components during transient loading during a full Cold Start procedure. The result of this study was the successful validation of the 1D and 3D Turbine models against plant data from the candidate unit. This was in the form of known process data of unit performance, as well as thermocouple and differential expansion data taken from sensors housed on the turbine unit itself. Through the validation of these parameters, various calibrations techniques were developed over the course of the study with these techniques allowing investigators to gain insight into turbine aging, operator intervention as well as brought turbine component response. The successful establishment of the paired turbine model allowed investigators to evaluate the cold clearances defined during construction and maintenance of these turbine units in industry, which contributes greatly to the availability and efficiency of the unit during these transient operations. Additionally, the establishment of this model allowed for the investigation of the role that start up speed has on turbine component response. This study demonstrated that the development of such a modelling methodology was possible and yielded results with were accurate and insightful in understanding turbine component responses which are otherwise impossible to measure during real-world operation.

Traditionally the reactor is recognised as the `heart' of a chemical process system and hence the focus on this part of the system is usually quite detailed. Steam reforming, however, due to the `building block' nature of its reaction products is unusual and generally is perceived as a `utility' to other reaction processes and hence the focus is drawn " towards the 'main' reaction processes of the system. Additionally as a `mature' process, steam reforming is often treated as sufficiently defined for the requirements within the overall chemical process. For both primary and secondary steam reformers several models of varying complexity were developed which allowed assessment of issues raised about previous models and model improvements; drawing on the advancements in modelling that have not only allowed the possibility of increasing the scope of simulations but also increased confidence in the simulation results. Despite the complex nature of the steam reforming systems, a surprisingly simplistic model is demonstrated to perform well, however, to improve on existing designs and maximise the capability of current designs it is shown that more complex models are required. After model development the natural course is to optimisation. This is a powerful tool which must be used carefully as significant issues remain around its employment. Despite the remaining concerns, some simple optimisation cases showed the potential of the models developed in this work and although not exhaustive demonstrated the benefits of optimisation.

No / The study is based on a previously proposed methodology for multiaxial fatigue life assessment of injection-molded components (called ‘Through Process Modeling’ (TPM)). The present contribution focuses on stress concentration effects induced in notched samples. Purely macroscopic approaches are unable to capture the different mechanical responses of variably injected parts with the same shape. A high interest of the present method is to take into account the difference of fiber orientation resulting from the process. After briefly reminding the TPM method, it will be shown that good lifetime estimations are obtained for laterally injected samples, from a fatigue criterion identification based on longitudinally injected ones.

No / Polymer extrusion is regarded as an energy-intensive production process, and the real-time monitoring of both energy consumption and melt quality has become necessary to meet new carbon regulations and survive in the highly competitive plastics market. The use of a power meter is a simple and easy way to monitor energy, but the cost can sometimes be high. On the other hand, viscosity is regarded as one of the key indicators of melt quality in the polymer extrusion process. Unfortunately, viscosity cannot be measured directly using current sensory technology. The employment of on-line, in-line or off-line rheometers is sometimes useful, but these instruments either involve signal delay or cause flow restrictions to the extrusion process, which is obviously not suitable for real-time monitoring and control in practice. In this paper, simple and accurate real-time energy monitoring methods are developed. This is achieved by looking inside the controller, and using control variables to calculate the power consumption. For viscosity monitoring, a 'soft-sensor' approach based on an RBF neural network model is developed. The model is obtained through a two-stage selection and differential evolution, enabling compact and accurate solutions for viscosity monitoring. The proposed monitoring methods were tested and validated on a Killion KTS-100 extruder, and the experimental results show high accuracy compared with traditional monitoring approaches.

No / This paper describes an institutional strategy (Ecoversity) to embed sustainable development across the full range of university activities and services and reflects on two different phases of Ecoversity providing illustrations and case examples of specific actions and changes that have occurred. The programme has begun to deliver tangible benefits to the institution and has begun to act as a catalyst for, and link up with other, internal initiatives that are seeking to reshape the university culture and core activities around sustainable development. The paper reflects on the process of change and describes a process model that captures many of the key elements that needed to be addressed to initiate change and scale up activities. The process model is helpful in analysing barriers to change and how change can be achieved. The project illustrates a conscious and deliberate process for embedding SD within a university culture and offers a coherent conceptual framework for describing change

Sales are a subject that most people consider to be an art. The truth is that there are several sophisticated methodologies on how to successfully close a deal. However, time goes by, customers get smarter and the markets shifts. As a result sales methods start to fade away and do not necessarily work the way they used to. This thesis was conducted in co-operation with SimCorp A/S and aims to examine the concept of Insight Selling. The concept was developed by analysing top performers and how they manage to sell in an economic downturn. The purpose is to investigate how an organisation can apply the core principles of the new sales strategy on an existing sales process and current customer relationship management system. A qualitative research method was used and interviews were conducted to gather data to gain a deeper understanding on the topic of sales. The result exhibits a situation analysis that was conducted to create a representation of SimCorp’s current sales process. With the key elements of insight selling a proposed model of a future state was presented. Lastly, a requirements analysis of the customer relationship management system currently deployed at the company was designed based on the findings. The result indicated that it was possible to apply the key elements of insight selling on the current sales process. The method might be suitable for some situations but it does not replace or eliminate earlier practices. / Det är vanligt att uppfatta försäljning som en konst. Sanningen är att det finns väl beprövade metodiker för hur man ska lyckas för att sälja. Med tiden har konsumenter blivit smartare och marknaden förändrats. Detta har resulterat i att många säljmetoder blir avlägsna och inte lika användbara och pålitliga som de var innan. Examensarbetet utfördes i samarbete med SimCorp A/S där syftet är att undersöka begreppet insiktsförsäljning. Konceptet utvecklades från en studie där man analyserade de högpresterande säljarna och identifierade hur de lyckades sälja under en ekonomisk lågkonjunktur. Syftet är att undersöka hur en organisation kan applicera de nya strategierna som presenteras inom insiktsförsäljning på en befintlig försäljningsprocess och det nuvarande kundhanteringssystemet. En kvalitativ forskningsmetod applicerades och intervjuer utfördes för att ackumulera data och få en djupare förståelse av ämnet försäljning. I resultatet presenteras en nulägesanalys av SimCorp’s nuvarande försäljnings-process. Vidare presenteras ett förslag på hur en försäljningsprocess med inslag av strategierna från insiktsförsäljning kan se ut. Slutligen utfördes en kravanalys på insiktsförsäljnings metod för att implementeras och testas på det nuvarande kundhanteringssystemet. Resultatet indikerade att det var möjligt att applicera nyckel elementen från insiktsförsäljning på den nuvarande säljprocessen. Metoden är lämplig för att användas i vissa situationer men ersätter inte eller eliminerar tidigare rutiner.
