Comparing Concept Drift Detection with Process Mining Software

Organisations have seen a rise in the volume of data corresponding to business processes being recorded. Handling process data is a meaningful way to extract relevant information from business processes with impact on the company's values. Nonetheless, business processes are subject to changes during their executions, adding complexity to their analysis. This paper aims at evaluating currently available process mining tools and software that handle concept drifts, i.e. changes over time of the statistical properties of the events occurring in a process. We provide an in-depth analysis of these tools, comparing their differences, advantages, and disadvantages by testing against a log taken from a Process Control System. Thus, by highlighting the trade-off between the software, the paper gives the stakeholders the best options regarding their case use

Äriprotsessimudelite ühildamine

Väitekirja elektrooniline versioon ei sisalda publikatsioone.Ettevõtted, kellel on aastatepikkune kogemus äriprotsesside haldamises, omavad sageli protsesside repositooriumeid, mis võivad endas sisaldada sadu või isegi tuhandeid äriprotsessimudeleid. Need mudelid pärinevad erinevatest allikatest ja need on loonud ning neid on muutnud erinevad osapooled, kellel on erinevad modelleerimise oskused ning praktikad. üheks sagedaseks praktikaks on uute mudelite loomine, kasutades olemasolevaid mudeleid, kopeerides neist fragmente ning neid seejärel muutes. See omakorda loob olukorra, kus protsessimudelite repositoorium sisaldab mudeleid, milles on identseid mudeli fragmente, mis viitavad samale alamprotsessile. Kui sellised fragmendid jätta konsolideerimata, siis võib see põhjustada repositooriumis ebakõlasid -- üks ja sama alamprotsess võib olla erinevates protsessides erinevalt kirjeldatud. Sageli on ettevõtetel mudelid, millel on sarnased eesmärgid, kuid mis on mõeldud erinevate klientide, toodete, äriüksuste või geograafiliste regioonide jaoks. Näiteks on äriprotsessid kodukindlustuse ja autokindlustuse jaoks sama ärilise eesmärgiga. Loomulikult sisaldavad nende protsesside mudelid mitmeid identseid alamfragmente (nagu näiteks poliisi andmete kontrollimine), samas on need protsessid mitmes punktis erinevad. Nende protsesside eraldi haldamine on ebaefektiivne ning tekitab liiasusi. Doktoritöös otsisime vastust küsimusele: kuidas identifitseerida protsessimudelite repositooriumis korduvaid mudelite fragmente, ning üldisemalt -- kuidas leida ning konsolideerida sarnasusi suurtes äriprotsessimudelite repositooriumites? Doktoritöös on sisse toodud kaks üksteist täiendavat meetodit äriprotsessimudelite konsolideerimiseks, täpsemalt protsessimudelite ühildamine üheks mudeliks ning mudelifragmentide ekstraktimine. Esimene neist võtab sisendiks kaks või enam protsessimudelit ning konstrueerib neist ühe konsolideeritud protsessimudeli, mis sisaldab kõikide sisendmudelite käitumist. Selline lähenemine võimaldab analüütikutel hallata korraga tervet perekonda sarnaseid mudeleid ning neid muuta sünkroniseeritud viisil. Teine lähenemine, alamprotsesside ekstraktimine, sisaldab endas sagedasti esinevate fragmentide identifitseerimist (protsessimudelites kloonide leidmist) ning nende kapseldamist alamprotsessideks

Activity-Oriented Clustering Techniques in Large Process and Compliance Rule Repositories

Organizations often have to deal with large collections of business process models and compliance rules. Particular challenges in this context are compliance checks, consistency checks, and the maintenance of the process and rule repositories. In case that a-priory knowledge about dependencies within the process base and the rule base is not available, compliance checking must be performed by verifying all rules for each process, which turns out to be very costly in a context of large process and rule repositories. In this paper we present activity-oriented clustering techniques for efficient compliance checking which are particularly applicable in process and rule repositories where no a-priori clustering is considered. Further it is shown how the proposed clustering techniques influence the complexity of consistency checks. Finally, qualitative and quantitative aspects of the presented clustering techniques are discussed. The presented techniques provide a first step towards effective and efficient management of large business process and compliance rule repositories

Enabling Process Variants and Versions in Distributed Object-Aware Process Management Systems

Business process variants are common in many enterprises and properly managing them is indispensable. Some process management suites already offer features to tackle the challenges of creating and updating multiple variants of a process. As opposed to the widespread activity-centric process modeling paradigm, however, there is little to no support for process variants in other process support paradigms, such as the recently proposed artifact-centric or object-aware process support paradigm. This paper presents concepts for supporting process variants in the object-aware process management paradigm. We offer insights into the distributed object-aware process management framework PHILharmonicFlows as well as the concepts it provides for implementing variants and versioning support based on log propagation and log replay. Finally, we examine the challenges that arise from the support of process variants and show how we solved these, thereby enabling future research into related fundamental aspects to further raise the maturity level of data-centric process support paradigms

Business process model repositories : efficient process retrieval

As organizations increasingly work in process-oriented manner, the number of business process models that they develop and have to maintain increases. As a consequence, it has become common for organizations to have collections of hundreds or even thousands of business process models. When a collection contains such a large number of business process models, it is impossible to manage that collection manually. Therefore, Business Process (BP) Model Repositories are required that store large collections of process models and provide techniques for managing these collections automatically and efficiently. The goal of research described in this thesis is to improve on existing BP Model Repositories, by improving the management techniques that are supported by these repositories on an aspect that has received little attention so far. Looking ahead at the results of the research, the aspect that will be selected for improvement is the process retrieval aspect. The two main research activities that will be carried in the context of this research are the following. Firstly, a survey of Business Process Model Repositories is performed to identity an unsolved aspect to be enhanced. The functionality of existing BP Model Repositories is listed and summarized as a framework for BP Model Repositories. After comparing the functionality that is provided by existing BP Model Repositories, based on the framework, efficient process retrieval is selected as the aspect that will be improved. This aspect is selected, because, although existing BP Model Repositories provide techniques for process retrieval, none of them focus on the efficiency of process retrieval. Secondly, an indexing technique for process retrieval (both process similarity search and process querying) is proposed. The index is constructed using features of process models. Features are small and characteristic fragments of process models. As such, by matching features of a given query/search model and features of a process model in a collection, a small set of models in the collection that potentially match the query/search model can be retrieved efficiently through the index. Techniques are also proposed to further check whether a potential match is an actual match for the query/search model. All of the above techniques are implemented as a component of the AProMoRe (an Advanced Process Model Repository) process repository. To evaluate the proposed process retrieval techniques, experiments are run using both real-life and synthetic process model collections. Experimental results show that on average the process retrieval techniques proposed in this thesis performs at least one order of magnitude faster than existing techniques

INDONESIA: Proses bisnis merupakan hal yang tidak bisa dipisahkan dengan dunia bisnis. Proses bisnis dapat menjadi sebuah pedoman dalam menjalankan sebuah bisnis agar sesuai dengan visi dan misi perusahaan. Salah satu masalah yang sering terjadi adalah pengelolaan data yang masih manual yang menyebabkan tingkat duplikasi data cukup tinggi dan ketidakrapian dalam pengelolaan tempat dokumen perusahaan yang menyebabkan penumpukan kertas-kertas dokumen perusahaan. Pada akhirnya perusahaan dituntut untuk menggunakan sistem informasi guna mengelola data tersebut dengan baik. Namun, permasalahan muncul diantaranya adalah sistem informasi yang belum sesuai dengan kebutuhan perusahaan dimana terdapat lebih dari satu sistem informasi yang digunakan. Biaya dalam membuat sistem informasi tersebut juga terhitung mahal serta dalam pengembangan fitur- fiturnya yang menyesuaikan perubahan proses bisnis yang dijalankan. Dalam hal ini dibutuhkan sebuah sistem informasi yang dapat menyelesaikan permasalahan- permasalahan tersebut. Sehingga biaya bukan lagi menjadi masalah, pengembangan fitur menjadi lebih mudah dan dapat disesuaikan dengan proses bisnis yang berjalan. Pada penelitian ini dibangunlah sebuah sistem yang dapat menyesuaikan proses bisnis yang dijalankan sebuah perusahaan yang disebut Sistem BPM. Dalam penelitian ini menggunakan pendekatan proses bisnis dalam penggunaan sistem tersebut sehingga sistem bersifat flexible dan reusable. Flexible dalam hal ini adalah sistem dapat dijalankan sesuai dengan proses bisnis yang diinputkan. Sedangkan reusable dalam hal ini adalah web service yang disediakan oleh sistem dapat digunakan pada proses bisnis lain. Adapun studi kasus pada penelitian ini melibatkan Syariahrooms Hospitality dan penelitian ini berhasil membangun sistem BPM yang bersifat flexible dan reusable. ENGLISH: Business processes are an inseparable part of the business world. Business processes can be a guideline in running a business to match the company's vision and mission. One of the most common problems is manual data management which causes a high level of data duplication and untidiness in the management of the company's document space which causes the accumulation of company documents. In the end, companies are required to use information systems to manage the data properly. However, problems that arise include the information system that is not in accordance with the needs of the company where there is more than one information system used. The cost in making the information system is also quite expensive and in developing its features that adapt to changes in the business processes that are carried out. In this case we need an information system that can solve these problems. So that cost is no longer a problem, feature development becomes easier and can be adapted to current business processes. In this research, a system is built that can adjust the business processes run by a company called the BPM System. This research uses a business process approach in using the system so that the system is flexible and reusable. Flexible in this case is the system can be run according to the inputted business processes. While reusable in this case is a web service provided by the system that can be used in other business processes. The case study in this study involved Syariahrooms Hospitality and this research succeeded in building a flexible and reusable BPM system.
