international conference on enterprise distributed object computing (EDOC)

作者： Bernd Michelberger Bela Mutschler Manfred Reichert University of Applied Sciences Ravensburg-Weingarten Germany Institute of Databases and Information Systems University of Ulm Germany

Today, enterprises are confronted with a continuously increasing amount of data. Examples of such data include office files, e-mails, process descriptions, and data from process-aware information systems. this data overload makes it difficult for knowledge-workers to identify the information they need to perform their tasks in the best possible way. Particularly challenging is the alignment of process-related information with business processes. In fact, process-related information and business processes are usually managed separately. On the one hand, enterprise content management systems, shared drives, and Intranet portals are used for organizing information, on the other hand, process management technology is used to design and enact business processes. With process-oriented information logistics (POIL) this paper presents an approach for bridging this gap. POIL enables the process-oriented and context-aware delivery of process-related information to knowledge-workers. We also present a clinical use case and a proof-of-concept prototype to demonstrate the application and benefits of POIL.

Visual Analysis of enterprise Models

Visual Analysis of Enterprise Models

international Workshop on enterprise distributed object computing, EDOCW

作者： David Naranjo Mario Sánchez Jorge Villalobos Department of Systems and Computing Engineering Universidad de los Andes Bogotá Colombia

In enterprise Architecture (EA) model analysis activities, it is critical to make early statements and diagnosis from a high level of abstraction. Currently, these tasks are difficult to perform, and they require both the involvement of experts and the elaboration of specialized artifacts. Further-more, the complexity of the tasks increases as models become bigger, more detailed, and start covering more domains. In other contexts, it has been noticed that total / holistic / unfiltered visualizations may give insight about the models, providing analysts a starting point for exploration and general pattern discovery. In this paper, we offer an evaluation framework to assess the strengths and weaknesses of visualization tools to support EA analysis activities. the framework is based on a set of 14 requirements which are either visualization-related or specific to EA analysis, and which where harvested from experimentation and from a survey of current EA and visualization tools. the requirements were defined around the design principle of cognitive effectiveness, and they favor a broader use of visual languages in order to enhance the semantics of EA visualizations.

Obligations and Delegation in the ODP enterprise Language

Obligations and Delegation in the ODP Enterprise Language

引用

international Workshop on enterprise distributed object computing, EDOCW

作者： Peter F. Linington Hiroshi Miyazaki Antonio Vallecillo University of Kent Canterbury UK Fujitsu Japan University of Malaga Malaga Spain

the ODP enterprise Language is used to describe the organizational objectives and policies that apply to the system to be specified. It also captures constraints associated with the environment in which the system is to be used. Because the enterprise specification is concerned more with organizational issues than technical details of the system, there is considerable emphasis in the language design on obligations and norms, rather than on the declaration of some single rigidly required behaviour. this leads to a requirement for specification techniques that encompass a wide range of behaviour and then identify which behaviour should occur and how exceptions are to be handled, this is more challenging than computational specification, where the specification is essentially a recognizer for correct behaviour and does not define what is to happen if there are violations. this paper describes work currently in progress within the international Organization for Standardization (ISO) to extend the enterprise Language so that it is able to express more directly the necessary obligations and other deontic concepts, such as permissions and prohibitions. the approach being taken is to introduce a new kind of object that reifies the deontic constraints and thereby simplifies the description of the behaviour expected. Once the basic concepts are in place, they can be used to define a wide range of organizational matters, such as delegation rules and the way communities respond dynamically to changes in their structure.

international conference on enterprise distributed object computing (EDOC)

作者： Tobias Binz Frank Leymann Alexander Nowak David Schumm Institute of Architecture of Application Systems University of Stuttgart Stuttgart Germany

the software systems running in an enterprise consist of countless components, having complex dependencies, are hosted on physical or virtualized environments, and are scattered across the technical infrastructure of an enterprise, ranging from on-premise data centers up to public cloud deployments. the resulting topology of the current IT landscape of an enterprise is often extremely complex. We show that information about this complex ecosystem can be captured in a graph-based structure, the enterprise topology graph. We argue that, using such graph-based representation, many challenges in enterprise Architecture Management (EAM) can be tackled through the aid of graph processing algorithms. However, the high complexity of an enterprise topology graph is the main obstacle to this approach. An enterprise topology graph may consist of millions of nodes, each representing an element of the enterprise IT landscape. Further, these nodes comprise a large variety of properties and relationships, making the topology hardly manageable by human users and software tools. To address this complexity problem, we propose different mechanisms to make enterprise topology graphs manageable. Segmentation techniques, tailored to specific use cases, extract manageable segments from the enterprise topology graph. Based on a set of formally defined transformation operations we then demonstrate the power of the approach in three application scenarios.

Compositional QoS Modeling and Analysis of Cloud-based Federated Ecosystems

作者： Guijun Wang Haiqin Wang Sharon Arroyo Robert Rencher James Tjelle Boeing Research & Technology The Boeing Company USA

In this paper, we present an approach to modeling and analyzing the quality of service (QoS) characteristics of compositional cloud services in a federated ecosystem. Our approach first synthesizes service compositions of federated services into a small number of primitive models, basic elements and associative characteristics as common patterns, each of which has an analytical model of its QoS characteristics. A cloud-based federated system is defined through recursive composition of the primitive models and thus can be modeled and analyzed through a decomposition and aggregation process based on the QoS characteristics of primitive models. the main objective of our approach is to support the design of cloud-based federated ecosystems and the management of service level agreements for business applications in such systems. We examine cases and conditions within which a composite model's QoS characteristics have analytical solutions as a composition of the QoS characteristics of primitive models and those that may not have an analytical solution and therefore simulation-based solutions are required. Test results are discussed for comparison of analytical and simulation approaches.

Coverage Estimation in Heterogeneous Visual Sensor Networks

Coverage Estimation in Heterogeneous Visual Sensor Networks

引用

international conference on distributed computing in Sensor Systems (DCOSS)

作者： Mahmut Karakaya Hairong Qi Electrical Engineering and Computer Science Department University of Tennessee Knoxville TN USA

Coverage estimation is one of the fundamental issues in many applications of sensor networks. Coverage estimation in visual sensor networks (VSNs) is more challenging than in conventional 1-D scalar sensor networks (SSNs) due to the directional sensing characteristic of cameras and the existence of visual occlusions in crowded environments. Moreover, deployment of heterogeneous visual sensors and existence of heterogeneous targets in the sensing field makes the coverage estimation problem even more challenging. In this paper, we study the coverage estimation problem in heterogeneous VSNs. We first investigate into a new target detection model, referred to as the "certainty-based target detection" as compared to the traditional "occupancy-based target detection" to facilitate the formulation of the visual coverage estimation. By adopting the new target detection model, we then derive the closed-form solution for the visual coverage estimation problem in heterogeneous VSNs. Our formulation also allows us to take both the presence of visual occlusions and boundary effect into consideration. Results from simulation validate the theoretical formulation, especially when the boundary effect is considered.

Research in enterprise system security has largely focused on the development of theoretical models capable of demonstrating mathematically that they possess desired security properties. However, recent results confirm that many of these models cannot be applied in practice because of the unpredictability of human participants' behavior in business processes. Moreover, while malicious attacks remain a significant problem, the majority of user-caused information leaks in enterprise Systems are unintentional (or have many unintentional components) and could potentially be prohibited if explicitly recognized and appropriately modeled. In this paper we argue that approaches for achieving information flow security in enterprises need to combine process and policy understandability with usability of the enforcement mechanisms. We present a modeling approach that allows security policies to be formulated in such a way that (1) they are aligned to the business processes executed in an enterprise, (2) are understandable by all relevant stakeholders, and (3) can be semi-automatically transformed into run-time enforcement mechanisms.

Vocabulary Model Requirements for Production Rule Systems

Vocabulary Model Requirements for Production Rule Systems

作者： Mukundan K. Agaram Chang Liu Enterprise Architect Delta Dental of Michigan Okemos USA Lead Developer Delta Dental of Michigan Okemos USA

Software solutions for certain complex problem areas such as claims adjudication and fraud detection are hard to build using imperative programming languages and even harder to maintain and change. In light of this, enterprises are turning to Rule-Based Expert Systems to provide a solution. However, to realize the full potential of this, the technology for mining and articulating the knowledge need to be made available to the Subject Matter Experts in a natural language like format. Further, this knowledge is best captured as production rules that can preferably be transformed and executed on production rule engines. Semantics of Business Vocabulary and Business Rules (SBVR) specification provides a framework for defining a formal language for specifying high level non-production business rules. the intent of SBVR is to capture these high level business rules in a formalized unambiguous format. However, this does not readily lend itself to a Production Rule System format. this paper explores the requirements surrounding the modeling of domain vocabularies that can be used to specify user friendly rules which can readily be transformed to executable production rule syntax and semantics of a target production rule engine.

Purchasing and Offering of Cloud Software Services by a Central Procurement Agency: A Case Study

international Workshop on enterprise distributed object computing, EDOCW

作者： Valère Dussaux Universitè Paris–Sud MIAGE Orsay France

the cooperative purchasing model has since long been used by government entities to obtain better purchase conditions through the power of aggregation. In particular, the âPiggypackâ option which consists in bridging a contract from one entity to another in an ethical way has been almost globally generalized since 2005. Although cloud software services are natively designed for convergent needs, its apparent attractiveness has to be precisely qualified, especially in the cases where this "Piggyback" option is contractually defined. In this paper, we study the specific problems that can be experienced in the definition process of cloud software services when implementing cooperative procurement. In particular, we show the particular importance of the scalability of the contractually defined SLA themselves in this context. We propose some best practices. One is based on the use of meta-SLA and sub-SLA concepts. It is illustrated by an application on an innovative governmental cloud software services implementation program that was already described before. this leads to a better understanding of the role played by central procurement agencies in the definition of cloud software services.

Memory-based methods for recommending data services predict the ratings of active users based on the information of other similar users or items, where the similarity algorithm always plays a key role. In many scenarios, we find that the similarity of two users always show different effectiveness when predicting different ratings. Normal similarity algorithms usually do not count the difference, since they originate from statistic and algebra fields and do not directly aim at recommendations. this paper proposes a novel method to amend the user similarity generated by a normal similarity algorithm to more accurately describe the effectiveness of the similarity on a targeted item. We apply our method to improve the Pearson Correlation Coefficient (PCC) algorithm which is one of the most commonly used similarity algorithms. the experiment results on some practical datasets show that our method is slightly better than the original PCC algorithm for predicting ratings in recommendations.
