Enterprise SPICE Based Education Capability Maturity Model

In the context of knowledge society, education became one of the most critical systems. The quality of all other systems strongly depends on the quality of education system as never before. The purpose of this paper is to address the problem of quality of education system. An approach to solve this problem is based on the main assumption that education is a process oriented activity. According to this approach, product quality can be achieved by the means of process quality – process capability. Introduced here, SPICE conformant education process capability maturity model is based on process capability maturity modeling elaborated by world-wide software engineering community during the last 25 years, namely ISO/IEC 15504 that defines the capability dimension and the requirements for process definition and domain independent integrated model for enterprise-wide assessment and improvement Enterprise SPICE. A participative approach is proposed for education process assessment and improvement.

Intellectual Model-Based Configuration Management Conception

Abstract Software configuration management is one of the most important disciplines within the software development project, which helps control the software evolution process and allows including into the end project only tested and validated changes. To achieve this, software management completes certain tasks. Concrete tools are used for technical implementation of tasks, such as version control systems, servers of continuous integration, compilers, etc. A correct configuration management process usually requires several tools, which mutually exchange information by generating various kinds of transfers. When it comes to introducing the configuration management process, often there are situations when tool installation is started, yet at that given moment there is no general picture of the total process. The article offers a model-based configuration management concept, which foresees the development of an abstract model for the configuration management process that later is transformed to lower abstraction level models and tools are indicated to support the technical process. A solution of this kind allows a more rational introduction and configuration of tools

Introduction to Lean Canvas Transformation Models and Metrics in Software Testing

Abstract Software plays a key role nowadays in all fields, from simple up to cutting-edge technologies and most of technology devices now work on software. Software development verification and validation have become very important to produce the high quality software according to business stakeholder requirements. Different software development methodologies have given a new dimension for software testing. In traditional waterfall software development software testing has approached the end point and begins with resource planning, a test plan is designed and test criteria are defined for acceptance testing. In this process most of test plan is well documented and it leads towards the time-consuming processes. For the modern software development methodology such as agile where long test processes and documentations are not followed strictly due to small iteration of software development and testing, lean canvas transformation models can be a solution. This paper provides a new dimension to find out the possibilities of adopting the lean transformation models and metrics in the software test plan to simplify the test process for further use of these test metrics on canvas.

Model-based approach for implementation of software configuration management process

Software configuration management is a discipline that controls software evolution process. Nowadays this process is not only challenge to choose the best version control system o branching strategy for particular project. Together with source code management the following tasks should be solved: continuous integration, continuous delivery, release management, build management etc. Usually software development companies already have a set of tools to support mentioned processes. The main challenge is to adopt this solutions to new projects as soon as possible with minimum efforts of manual steps. The article provides new model-driven approach to increase reuse of existing solutions in configuration management area. In order to illustrate the approach, there were developed new meta-models that are purposed for development of different configuration management models in context of a model-driven approach. This article provides a simplified example to illustrate models and defines further researches.

Modelling the performance of adaptive multi-boiler heating system

In up-to-date conditions information technology is frequently associated with the modelling process, using computer technology as well as information networks. The simulation model can be used for complex problems (with many related values) in order to conduct advanced research. This article describes the method of assessing the economic efficiency modelling of a multi-boiler adaptive heating system in real-time systems which allows for dynamic change in the operation scenarios of system service installations while enhancing the economic efficiency of the system in consideration.

Analysis of wireless sensor network structure and life time affecting factors

In the recent years low power computing systems have gained popularity. Networks, which use low power computer systems and transmitted data by using wireless connection are called wireless sensor networks. Nowadays, the most topical researches pertaining to wireless sensor networks are grounded on the new optimization of structure of network transmission protocol, the routing optimization in transmission network, optimization of network structure, as a result of which the life circle of wireless network sensors is possible to increase. This paper provides a structural view on the life expectancy of a wireless sensor network with an autonomous power supply without the option of renewing energy. The factors, that affect total life expectancy of a wireless sensor network are defined as well.

Simulation-Based Experimental Research of Wireless Sensor Network Life Expectancy Reconfiguration Method in Transport Logistics Area

Nowadays in cargo identification process are used different type of sensors (GSM, GPS, RFID and others) tocontrol and manage cargo data process. Existing technologies allow to identify container location on map or container Traffic load history. This technology has problems using it in limited area (board, train, container terminal) because of location services limitation. In case, if containers are located close to each other or placed one on one, location services will not give correct position of necessary item. Adaptive wireless sensor network can identify each with sensor equipped itemand display its location relative to other items in set position. In result adaptive wireless network in real live creates 3D items location map with from available sensors received information (item temperature, weight, radiation etc.). This article will discuss the simulation tool for the assessment of a wireless sensor network life circle that ensures the configuration of optimal network and projection/displaying of topology operations by using energy balancing methods.

Models and Methods of Software Configuration Management

Abstract The paper provides collection of experience of developing models and methods for implementation of software configuration management process. Nowadays, during the age of agility, startup of new software development projects is like an explosion. Sometimes, in a few days a customer is willing to get the first release, but formalized and reusable process for its creating is not ready yet. Software configuration management controls the evolution of software items and supports building and deployment process for product releases. Models and methods for implementation of software configuration management are presented in the paper. Unlike other approaches, the provided models and methods are related to decrease software configuration management implementation time in new projects. The paper provides a simplified use case to illustrate practical application of the mentioned methods and models.
