An approach to transformation of the business processes models, created with visual modelling tools, to the analytical models provided in the form suitable for the analysis with mathematical software tools is described. The procedure of process models transformation is described. De-scription of the developed software is presented. Key words: business processes modelling, visual modelling languages, model transformation, business process analysis.
The main output of planning the business analysis process is formation of a certain approach to business analysis execution. Such approach describes a process that should be followed during business analysis: terms of completing the tasks, methods used, as well as planned results of the project. Business analysts should pay attention on compliance between requirements and business needs, during the whole iterative planning process, especially regarding developing and transformation of business goals over time. The novelty of the paper is that authors developed an adaptive approach to business analysis planning using Agile methodology. This approach may provide competitive advantage for a company, in rapidly changing and complex environments.
Abstract: An approach to reengineering business processes through the integration of the domain specific modeling platform and Process Mining tools is described. An analysis of the existing approaches to business processes improvement is presented and restrictions are shown. The Process Mining methods are related to business process reengineering stages and tasks. Comparative analysis of Process Mining tools is executed. The advantages of the using of domain specific modeling tools (language workbenches, DSM platforms) are substantiated. Brief comparison of various visual languages notations and model transformation examples are described. The DSM platform ensures mutual understanding between specialists.

Abstract: The approach to models generation automation and implementation of multifaceted business process modeling on the basis of graphical model transformation is described. To create graphical models of diverse notations (diagrams in notations of visual modeling languages) one can exploit visual modeling software tools and language workbenches, DSM platforms. Domain specific modeling tools allow simplifying model design process, to involve domain experts (they are not masters of information technologies and have not programming skills) to formal model development. Newly-created models can be converted into simulation models or specific analytical models with the model transformation tools. Therefore, at new task solving process with modeling tools modelers have not to duplicate model development with new tools in new language notation. Model designers can use most suitable tools and most expressive languages for models development in their domain to solve their tasks. Obtained models after transformation can be examined with means of specific simulation modeling systems including, for instance, AnyLogic, or with mathematical software packages such as Mathcad, Maple or Mathematica. The visual business process modeling notation choice is substantiated. Mathematical model named DFD-graph is used as mathematical basis of model generation tools. The normalization rules form the backbone to the DFD business process model normalization. This algorithm is the basis of automating model generation software implementation.

At the process of creation and maintenance of information systems the model-based approach to the software development is increasingly used. This approach allows to move the focus from writing of the program code with using general purpose language to the models development with automatic generation of data structures and source code of applications. However at usage of this approach it is necessary to transform models constructed by various categories of users at different stages of system creation with usage of various modeling languages. An approach to models transformation in DSM platform MetaLanguage is considered. This approach allows fulfilling vertical and horizontal transformations of the designed models. The Metalanguage system support “model-text” and “model-model” types of transformations. The component of transformations is based on graph grammars described by production rules. Transformations of model in Entity-Relationship notation are presented as example.

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
The geographic information system (GIS) is based on the first and only Russian Imperial Census of 1897 and the First All-Union Census of the Soviet Union of 1926. The GIS features vector data (shapefiles) of allprovinces of the two states. For the 1897 census, there is information about linguistic, religious, and social estate groups. The part based on the 1926 census features nationality. Both shapefiles include information on gender, rural and urban population. The GIS allows for producing any necessary maps for individual studies of the period which require the administrative boundaries and demographic information.
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.
