Метод определения противоречий в DEMO-моделях бизнес-процессов
The article analyzes the methods and provides a solution to the problem of detecting logical contradictions in business process models of the health care company. Practical purpose of solving the problem is to increase the efficiency of data management for municipal agencies as stakeholder of company. The methodology is based on formal tools relational logic formalism and the methodology involved is describing business processes by DEMO paradigm. Essentially used the simulator MIT Alloy Analyzer. Analyzed business processes specific organization, provides guidance on the elimination of contradictions.
By analyzing the logs of corporate e-mail networks we found a number of patterns, showing how the size of ego-networks of individual employees changes on a day by day basis. We proposed a simple model that adequately describes the observed time dependence of an employee's "social circle". Comparison of experimental data with the theoretical model showed that employees are divided into two groups - with fast and slow changes in their social circles, respectively. We believe that the presence of these groups reflects both project-type and process-type of employees' activities. Comparison of data obtained before and during the global economic crisis has shown that the crisis led to an actual reduction in project-type activities.
THE ROLE OF THE SUBJECTIVITY IN BUSINESS PROCESSES
The article is devoted to the research of the subjectivity, the subjective structure and the reflectiveness in the business-process management of the company. This research was made with the financial support of the government of the Russian Federation (Ministry of education and science of Russia) in frames of the contract №13.G25.31.0096 about “The creation of high technological production of cross-platform systems for processing the non-structured information on the base of freeware for increasing the efficiency of company innovation activity management in modern Russia”
Existing limitations and problems in the current life-cycle of software applications is expected to encourage new development paradigms. New technological trends, aimed at responding to current needs, such as flexibility, dynamics, scalability and creativity will drive the envisaged changes. This article describes the various types of business processes, ranging from structured workflows to semi-structured flexible business processes, and methods to model each type of business process. Development of business process models based on the knowledge economy, changing corporate strategy and organization design, and agile enterprise paradigm requires BPMS technology to support weakly structured business activities and emerging ad-hoc tasks. Increasingly, organizations are expanding the use of BPM beyond their initial focus on structured processes into more challenging, cross-boundary processes that include more unstructured components. Case management technology allows the modeling of cases in which a business goal is achieved by taking decisions in the context of documents and other content objects. Case management is considered dynamic because it focuses on unstructured and ad- hoc processes. It is likewise a continuing process that involves people, information, processes, and technical tools. Furthermore, it is adaptive and adaptable because it can be used by non-technical users and is versatile in its applications in different situations. With the use of case management, circuitous business processes, fragmented communication, repetitive operations, missing documents, and long approval times can be permanently abolished.
Workshop on Program Semantics, Specification and Verification: Theory and Applications is the leading event in Russia in the field of applying of the formal methods to software analysis. Proceedings of the fourth workshop are dedicated to formalisms for program semantics, formal models and verication, programming and specification languages, etc.
Inconsistency of business processes can affect company profits and lead to the loss of regular customers and reputation in the market. Well managed business process has one key distinctive feature – a consistency. Checking the consistency of business process helps to reveal hidden bugs in the process model, but requires considerable labor costs and analytics. We compared two approaches to verifying consistency. The first approach is based on generating object life cycles for each object type used in process and supported by special tool as an extension for IBM WebSphere Business Modeler. Another one is a proposition to use DEMO methodology for verifying consistency. The results of research show that DEMO methodology enables significantly reduce labor costs and improve quality of analyze
Highly competitive environment and constrained resources raise requirements as pertains to selection of projects for the portfolio of diversified IT-companies. Nowadays, vital task is to develope a business process that will guarantee efficient selection of optimal projects for the company's portfolio in terms of its stretegic goals. The paper presents an original business process for selecting projects to the portfolio of a diversified IT-company that best meet its strategic goals in the context of constrained resources. In addition, the paper classifies projects implemented by IT-companies and suggests evaluation criteria for various project groups.
This book consists of selected papers presented in the framework of the 16th International Conference on Perspectives in Business Informatics Research (BIR 2018), held in Stockholm, Sweden, September 24-26, 2018. The BIR conference series was established 16 years ago as the initiative of some German and Swedish universities with the aim of supporting the global forum for researchers in business informatics for their collaboration and exchange of results.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.

The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
Over the last two decades national policy makers drew special attention to the implementation of policy tools which foster international cooperation in the fields of science, technology, and innovation. In this paper, we look at cases of Russian-German collaboration to examine the initiatives of the Russian government aimed at stimulating the innovation activity of domestic corporations and small and medium enterprises. The data derived from the interviews with companies’ leaders show positive effects of bilateral innovative projects on the overall business performance alongside with major barriers hindering international cooperation. To overcome these barriers we provide specific suggestions relevant to the recently developed Russian Innovation Strategy 2020.
