Celem artykułu jest analiza teoretycznych koncepcji w dziedzinie aplikacji analitycznych. Po analizie pojęć są omawiane poszczególne kwestie programowe. Aplikacje analityczne są stosowane w logistyce, aby pomóc menedżerom w podejmowaniu właściwych decyzji. W pracy przedstawiono kilka przykładów zastosowania niestandardowych raportów w studium przypadku logistyki. Te przykładowe raporty mogą być generowane w ramach każdego systemu ERP (Enterprise Resource Planning) oraz mogą być stosowane do monitorowania kluczowych wskaźników wydajności (KPI). Proponują nowe odkrycia w zakresie zarządzania logistycznego. Chodzi o monitoring sprzedaży 1–2 przedmiotów. Na podstawie uzyskanych informacji przewidywana jest sprzedaż innych produktów. Omawiane są również zagadnienia dotyczące inwestycji w aplikacjach analitycznych.

The purpose of this article is to analyze the theoretical concepts in the field of analytical applications. After analyzing the concepts some software issues are discussed. Analytical applications are used in logistics to help managers to take correct decisions. The paper gives several examples of using custom reports in logistics case studies. These sample reports may be generated within any ERP (Enterprise Resource Planning) system and may be used for monitoring key performance indicators (KPIs). A new finding in the logistics management is proposed. The idea is to monitor the sales of 1-2 items. By using the gained information the sales of other products are predicted. Issues concerning investments in analytical applications are discussed.

Service-Oriented Architectures (SOA) allows software applications to interoperate in a new way in distributed environment. Currently, web services are the most widely adopted technology for implementation of SOA. However, they bring a number of challenges to development as well as to testing. Testing web service compositions is one of the major problems in SOA domain that is due to the unknown context, absence of web service source code, multiple provider coordination, lack of tool support, etc. In such context, the paper proposes a framework, named Testing as a Service Software Architecture (TASSA), which aims to provide design time testing of both functional and nonfunctional behavior of web service compositions described with Business Process Execution Language (BPEL). TASSA consists of set of tools that can be used together with existing development environments of service based applications. The paper focuses on an approach for negative testing and unit testing of BPEL processes. The negative testing is supported by TASSA tool, called Fault Injector tool, which implements a fault injection technique providing message delays, wrong message data, etc. The goal of unit testing is to test a BPEL process in isolation from its dependent web services. The isolation technique is implemented in another TASSA tool, named Isolation tool.

Mit Soft-SPS und Visualisierungsprogrammen, wie sie für Leitsysteme oder Mensch-Maschine-Schnittstellen genutzt werden, lassen sich die Erstellung und die Erprobung von SPS-Anwenderprogrammen auf einem PC durchführen. Dies eröffnet für Studierende die Möglichkeit mit „Computer Based Training“ selbst-ständig steuerungstechnische Kompetenz zu erwerben. Ein Übungsmodul durch den die Kenntnisse über die Arbeitsweise von SPS vertieft werden sollen wird vor-gestellt. Es ist ein Programm für die Addition von drei-stelligen ganzen Zahlen zu entwickeln. Der Programm-entwurf ist so zu strukturieren, dass die Teilschaltungen bereits während des Entwurfs erprobt werden können.

Purpose: The building of mathematic model, which enable description of urban public transport network is a purpose of the article. This model will make the estimation of public transport quality according to analysis of punctuality easier. Design/methodology/approach: The methodology of building the mathematical model of public transport network consists in application of the graph theory. The mathematical instruments make the description of real network easier. Findings: The mathematical model of public transport network on the proper level of aggregation may be effective instrument, which assists the decision process. It makes an estimation of chosen coefficients that describe public transport quality easier. Research limitations/implications: The research has been conducted only in the range of punctuality estimation for the sake of time-consuming and expenses. This limit also concerns database. It requires detailed description of public transport network to exact presentation in mathematic model. Originality/value: To make the calculations more efficient, the relative database has been built. It includes geometric parameters of the sections and junctions in network. It also covers all necessary detailed data of analysed public transport lines. The database is the ground for estimating punctuality in research area.
