Typically, these models are stored in a collection containing several hundreds of process models. In many cases, process models are overlapping, although parts could be easily reused saving costs and efforts. Different labeling styles and evolving process models complicate the detec- tion of reusable model parts. In this paper, we propose a novel approach for the detection of equivalent and similar process model parts that ex- ploits semantic comparison of activity labels and behavioral comparison of control flow. We evaluate our approach on the SAP Reference Model, a collection with 604 process models. The evaluation reveals insights for the thresholds of semantic and behavioral similarity of process models as well as their influence for similar process part detection. Hence, we identify five candidate groups with specific similarity properties that contain reoccurring process parts.}, language = {en} } @inproceedings{Towers2013, author = {Towers, Ian}, title = {Learning how to be a modern manager while sitting on the sofa: the role of television in diffusing and legitimising management practices}, series = {EGOS Conference 2013, Montr{\´e}al}, booktitle = {EGOS Conference 2013, Montr{\´e}al}, url = {http://nbn-resolving.de/urn:nbn:de:0298-opus4-352}, pages = {24}, year = {2013}, abstract = {What processes must have taken place so that HR managers or operations managers somehow 'know' that they have to do things differently from the way they did things five or fifteen years ago?

An ever increasing amount of attention has been paid to the first two of these stages, but relatively little has been paid to how management knowledge might be diffused through other methods.

In an age of Bring-Your-Own-Device, small businesses through to globally operating companies increasingly support their employees and customers with SaaS-applications that allow access to internal and external business information. Whether employees are in the office, at a client facility, at home or on the road, they need fast, easy access to business applications with any type of device. SaaS offers companies an interesting alternative to classical on-premise IT solutions. Cloud computing provides innovative applications, high connectivity and performance, cost reduction, flexibility and fast time to market with a minimum of effort. Cloud computing is a special form of outsourcing that has its roots in the fifties. Ten years ago similar concepts to cloud computing e.g. Application Service Providing (ASP) appeared and failed. But it seems that the willingness to use cloud computing is now much higher and the cost pressure effects of the financial crisis also motivate decision makers in companies to focus on cloud computing. This contribution presents the results of actual scientific literature investigations alongside interviews with owners of Software-as-a-Service Marketplaces. It describes several types of SaaS marketplaces using different business models to bring together customers and providers. It shows that SaaS marketplaces are two-sided and demonstrates how platforms are emerging that bundle features into significant value propositions for both sides. This work is relevant to firms who seek business solution recommendations beyond the focus of their on-premise-focussed advisors. It is also relevant for owners and potential owners of SaaS marketplaces and SaaS providers exploring alternatives in their distribution mix.}, language = {en} } @inproceedings{StantchevTamm2010, author = {Stantchev, Vladimir and Tamm, Gerrit}, title = {Towards Ambient Intelligence and the Internet of Services in Healthcare}, url = {http://nbn-resolving.de/urn:nbn:de:0298-opus4-727}, pages = {6}, year = {2010}, abstract = {The emergence of the Internet of Services and the Internet of Devices opens new possibilities for societal computung scenarios.

It works for functional and non-functional properties, it may consider both, hardware and software, and it allows for a description of composition anomalies.

While the group of elderly workers grows, their sustainment will become more important in future (e.g. H{\"o}hn et al. 2008; Dittrich et al. 2011). Especially in combination with an ageing population and a later entrance into the labour market a future shortfall of active workers can be assumed. Germany - as one example of such countries - has only a limited number of options that policy makers and companies can use in the coming decades. One of these is the increased use of the three growing segments in the population: older people, immigrants and an increased participation of women in the labour market. This study focuses the first segment as a potential work force. When promoting that a higher employment rate of older workers can be considered as serious alternative for dealing with the current shortfall of skilled labour force, the motivation of these workers has to be investigated. The works of Alavinia et al. (2007) and Wang, Shultz (2010), which discuss factors influencing the decision to prolong the working age, can be used as starting point. In this context, we analyse the German labour market as an example for a developed country. For the analysis, we use a representative data set of the Federal Institute for Population Research of Germany from published in2008. Here, 1,500 employees (blue collar workers, white collar workers, civil servants) aged between 55 and 64 years were asked about their work situation, motivation and related factors (e.g. further education, job rewards; B{\"u}sch et al. 2010). During the data analysis we identify groups of elderly workers using cluster analysis (e.g. Cormack 1971) to develop recommendations for companies. By using existing work motivation and related findings, as well as a representative empirical data set, our study reveals a possibility to identify, classify, and enhance the motivation of workers at the end of their career. This is necessary to keep the quality of goods and service production at an appropriate level. The value of the paper comes from the large number of respondents of the data set and the high relevance of the German situation for other developed countries. At the end, powerful recommendations for companies how to involve and motivate elderly workers for longer periods of employment can be derived.}, language = {en} } @inproceedings{BruschBueschAnte2011, author = {Brusch, Michael and B{\"u}sch, Victoria and Ante, Arta}, title = {Typology of Workers at the End of Their Career in Germany}, series = {13th International Conference on Combined Actions and Combined Effects of Environmental Factors, Tampere (Finnland)}, booktitle = {13th International Conference on Combined Actions and Combined Effects of Environmental Factors, Tampere (Finnland)}, year = {2011}, abstract = {Keine Angabe No details}, language = {en} } @inproceedings{MejiaGlasbergTammetal.2011, author = {Mejia, F. and Glasberg, Ronald and Tamm, Gerrit and Lopez, Gabriel J.}, title = {Readiness Level to adopt Smart Grid Technologies: Study for the City of Medellin}, isbn = {978-1-4577-1802-1}, year = {2011}, abstract = {The smart grid development in Latin America shows a big gap in the amount of research and development when compared with the USA and EU where the topic has been active for almost 10 years.

New technological innovations such as Internet of things (IoT), Smart item technology, and cloud computing can improve the traditional e-healthcare system and extend service provision beyond the hospital facilities by using wireless sensor networks (WSN) and radio frequency identification devices (RFID), providing a new type of services advertised as "smart." This type of services, enable doctors to treat patients remotely and allows people to do their normal daily routines, occupations, and activities while receiving appropriate, timely, and high-quality ubiquitous healthcare services. Methods: An exploratory study is performed to review the route towards smart healthcare services, emphasizing the use of information and communication technologies (ICTs) and smart item technology as enhancers for smart healthcare services provision. Results/findings: A new technological infrastructure promises to transform medical practice and disease prevention by empowering healthcare institutions with smart items for remote patient monitoring eliminating time-wasting procedures, reducing health costs, improving quality of service and patients satisfaction.

We first compare the cost structures of the classical licensing model with the new server-based approach. Then we illustrate how price and product differentiation may improve overall market efficiency. In particular, we show that by selling different software versions for different prices, ASP marketplaces may obtain near-optimal revenues with products that are relatively inexpensive, disaggregated, and customizable.
