Item type:Publication, Access status: without files , Towards living inter-organizational processesBusiness Process Management (BPM) has gained significant adoption in practice for enabling organizations to increase their effectiveness, efficiency, and flexibility. This broad adoption has not only been fostered by a rich and well-established theory to model, analyze, simulate, and enact business processes, but also by internationally accepted standards and mature technologies. Caused by the ever increasing speed and volatility of markets and the dynamics of new technologies, such as cloud infrastructures and mobile communications, we face a new generation of business processes, which we refer to as living inter-organizational processes. Such processes are not in control of one single organization, instead, they are enacted by multiple organizations, where no participating party possesses full control over the entire process. Such processes often involve a high number of actors that might even be unknown in advance. These actors require various degrees in participation, they are acting in heterogeneous environments. Moreover, such processes are often weakly structured or designed in an ad-hoc manner, and have to be continuously subject to evolution. Unfortunately, existing theories, methodologies, and technologies cannot cope with this challenging combination of aspects, which all have to be considered when dealing with living inter-organizational processes. The state of the art typically addresses singular aspects in isolation. However, a holistic approach to these challenges bears a tremendous potential. This paper aims to contribute towards a holistic approach to living inter-organizational processes. To this end, we describe different perspectives on inter-organizational processes and identify challenges for making them living processes.Publicationtype: Conference Paper41 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , An approach to minimize inhomogeneous stress distribution in compression testing of CFRPTo measure the compression strength of unidirectional Carbon Fibre Reinforced Plastics (CFRP) is difficult. Various compression tests show significant inhomogeneous stress states, leading to a multiple failure mode. In the new approach different lubricants between specimen and loading equipment were tested to reduce multiaxial stress state in the loading area. The test method was modelled by Finite-Element Analysis (FEA) using a multiple body contact model including different coefficients of friction between the bodies as well as plasticity. The unidirectional cylindrical specimens were tested under compression. The model predictions and the tests show good agreement in the deformed shapes under loading. Depending on the lubricant the failure changes from fibre buckling to a pure cross tensile failure. However, the compression strength is not highly dependent on the edge modification, whereas deviation and failure are.Publicationtype: Conference Paper19
