This paper focuses on application of technical debt prioritization technique to the telecommunication software managing the fleet of devices for a video surveillance system. Technical debt for this application was gathered, categorized and prioritized according to the approach named CoDVA. However, the implementation of technical debt reduction did not follow exactly the expected guidelines. The three main causes of this phenomenon were discovered: continuous refactoring approach, sizing of technical debt items, and the broadened scope of refactoring activities. Therefore, we propose to adopt a specific definition of technical debt and follow a few rules for defining its scope and granularity.

Purpose: The main purpose of the research is to examine the suitability of exploratory tests in the software testing process. Design/methodology/approach: An experiment, carried out for the sake of this study, consisted of two parts. First, a test was performed, and in the second part a survey was conducted, which allowed for the comparison of exploratory and test-based tests. Findings: The results of the tests indicated a slightly lower effectiveness of the exploratory approach, which may have been caused by the conditions of the experiment: the choice of the tested software, short duration of test sessions, participants lacking knowledge about the investigated software and experience in performing exploratory tests. Originality/value: Despite the weaker results obtained, the exploratory tests proved useful, as evidenced by the detection of distinctive errors, not found during tests based on test cases. In the survey, 90% of respondents confirmed the use of formalized test approach, based on test cases, while just over a half (57%) indicated having experience in conducting exploratory tests. Testers considered both approaches useful, addressing greater need for conducting formalized tests using test cases. Results included in the research allowed to indicate the qualities and shortcomings of the exploratory approach to software testing.

The paper presents the main results of software development for a new robotic technology of microplasma spraying of powder coatings to protect surfaces of industrial parts. The numerical methods have been implemented for modeling temperature fields induced by the radiation treatment of coatings. The proprietary software products have been developed to perform calculations of temperature fields in two-layer heat absorbers under irradiation and to provide the desired trajectory of a plasma source. The laboratory samples with coatings have been obtained.

Global competition and increasingly complex networks of supply chains require new production philosophies, novel supply chain paradigms (Lean, Agile and Hybrid ones) and new organization and cooperation forms of companies in order to reduce cost, increase productivity and boost competitiveness. Therefore, members of an Agile supply chain form a virtual enterprise (VE) network, which stands for temporary cooperation of VE members (final assemblers, suppliers, service providers) in which the members share their skills, human and equipment resources as well as waste for more efficient operation. The goal of this study is VE optimization, which means forming optimum combinations of potential chain members. This innovative and original approach involves developing an optimization method and defining objective functions (total cost, total lead time) and design constraints (production and service capacities, inventories and members flexibility) for optimum formation of VEs. The focus of VE optimization is to manufacture and deliver final products to customers in the most time- and cost-effective manner, with the total cost and total lead time of the supply chain being minimized during the optimization. Unique optimization software has been developed based on this method. It can can be widely used for optimizing micro- and macro regional virtual networks.

Changing market environment, global competition, rapidly fluctuating customer demands and more complex global network of supply chains require new production conceptions (Pull, Lean) and technologies. Novel supply chain paradigms (1. Lean-, 2. Agile-, 3. Leagile Supply Chain) are forms in order to increase and maintain competitiveness of companies. New organization and cooperation forms are formed. The members of an Agile Supply Chain form Virtual Enterprise (VE) network, which supports the fast and flexible fulfilment of changing customers’ demands. The goal of the study is the VE network optimization, which means the formation of optimal combination of ideal chain’s members (production companies, service providers and customers). This study is original and unique, since an optimization method, objective functions (total cost and lead time) and design constraints have been elaborated. Based on the elaborated method an optimization software has been developed which can be widely used for optimization of micro- and macro regional networks.

Zmiana otoczenia rynkowego, globalna konkurencja, gwałtowne wahania zapotrzebowania klientów i bardziej złożona globalna sieć łańcuchów dostaw wymagają nowych koncepcji produkcji (Pull, Lean) i technologii. Paradygmaty łańcucha dostaw (1. Lean-, 2. Agile-, 3. Leagile Supply Chain) są formami powstałymi w celu zwiększenia i utrzymania konkurencyjności firm. Powstają nowe formy organizacji i współpracy. Członkowie Łańcucha Agile Supply Chain tworzą sieć wirtualnego przedsiębiorstwa (Virtual Enterprise, VE), która zapewnia szybkie i elastyczne spełnianie zmieniających się wymagań klientów. Celem badania jest optymalizacja sieci VE, co oznacza tworzenie optymalnej kombinacji idealnych członków łańcucha (firm produkcyjnych, dostawców usług i klientów). Przedstawione badania są oryginalne i unikalne, ponieważ opracowano metodę optymalizacji, funkcje celu (całkowity koszt i czas realizacji) oraz ograniczenia projektowe. Na podstawie opracowanej metody opracowano oprogramowanie optymalizacyjne, które można szeroko wykorzystać do optymalizacji sieci mikro- i makroregionalnych.

In the paper we present our experience with development and maintenance of complex software systems. In particular, we concentrate on monitoring related development, testing and debugging processes. We have analyzed the contents of collected reports (provided by different tools) covering many projects and defined several metrics and statistics helpful in managing complex projects and achieving high quality software. Moreover, we have identified lacking data which could improve these processes.

W opracowaniu przedstawiono zagadnienie rozwoju, wytwarzania i wdrożenia oprogramowania korporacyjnego. W takim procesie ważne jest, aby współpraca pomiędzy przedsiębiorstwem rozwijającym oprogramowanie a przedsiębiorstwem, w którym to oprogramowanie było wdrażane, była bardzo efektywna. Na podstawie modeli korporacyjnych obu przedsiębiorstw można odwzorowywać model współpracy pomiędzy przedsiębiorstwami. W pracy przedstawiono w skrócie metodykę, która ma za zadanie rozwój oprogramowania korporacyjnego na bazie powiązań synergetycznych pomiędzy przedsiębiorstwami. Metodyka w zamierzeniu ma integrować najlepsze rozwiązania z dziedziny modelowania korporacyjnego, architektur zorientowanych na usługi oraz modeli wdrażania oprogramowania.

An CPDev environment for programming small distributed control-and-measu-rement systems in ST language (Structured Text) of IEC 61131-3 standard is presented. The environment involves ST compiler, configurer of hardware resources and simulator. The compiler generates an universal code thai can be executed on different platforms by Java-like virtual machines. The environment is open in terms of software and hardware, what means that the programmer can create his own libraries, and I/O and communication drivers can be written by hardware designers and linked with the universal code. It is possible to select a number of data types for particular applications. The environment has been created in C# on MS .NET Framework platform. First application for programming a distributed mini-system from LUMEL Zielona Góra is described.
