This study aims to design and improve the plant layout of a ceramic factory by adopting Systematic Layout Planning (SLP) and the simulation technique. A ceramic company in northern Thailand is selected as a case study. Three ceramic products including roof tiles, wall tiles and dishware are studied due to their highest production volume. Through the SLP approach, information regarding the number of departments and machines, the area of the plant, the frequency of movement and the distance between each department is collected for the analysis of the relationship between departments. Two plant layout designs are then proposed; the first one is derived from the Computerized Relationship Layout Planning algorithm (CORELAP), and the second one is the process layout. For selecting the most appropriate layout design, five criteria are considered including total distance, the average total process time of each unit produced, ease of movement, material flow and safety. To determine the distance and the average total process time per unit, Distance-Based Scoring and simulation techniques are conducted while the ease of movement, material flow and safety are rated based on whether the company satisfies each criterion. Employing the weight scoring technique, the results report that the CORELAP layout is the most suitable for further implementation due to its highest weighted score equal to 2.536 while the process layout receives 2.386. Implementing the CORELAP layout can reduce the total distance by 16.76% while the average total process time per unit of the CORELAP layout is not significantly different at the significance level of 0.05 as compared to the existing layout.

In recent years, scientific and technological advances have changed the modern battlefield, giving rise to new weapons systems and battle strategies. Apart from the challenges posed by new means and methods of warfare, soldiers are faced with an increasing need to rely on their language skills while joining multinational operations. To succeed in an international military environment, bridging the language gap is a must since it contributes to building and strengthening interoperability with NATO forces. The following article is intended to discuss the role of STANAG tests in developing language competence of Polish soldiers as reflected in the language training framework programme for the Polish military, with a focus on the speaking ability. Most importantly, the article highlights the contribution of language testing according to STANAG 6001 to developing interoperability with the Allies, presenting the main phases of the process. In the final part, the authoress attempts to determine to what extent this contribution is really made.

Ostatnie lata przyniosły ogromny postęp nauko-wy i technologiczny widoczny na współczesnym polu walki, pozwalający na wprowadzenie nowych systemów uzbrojenia i strategii prowadzenia działań zbrojnych. Oprócz wyzwań, jakie niosą ze sobą nowe środki i metody prowadzenia wojny, żołnierze stają przed coraz większą potrzebą wykorzystywania swoich umiejętności językowych, uczestnicząc w międzynarodowych operacjach wojskowych. Ujednolicenie kompetencji językowych jest warunkiem niezbędnym dla prawidłowego funkcjonowania w międzynarodowym środowisku wojskowym, przyczyniając się do wzmacniania partnerskiego współdziałania z siłami NATO. Poniższy artykuł miał na celu omówienie roli egzaminów STANAG w rozwijaniu kompetencji językowych żołnierzy RP, co znajduje odzwierciedlenie w ramowym programie szkolenia językowego dla Polskich Sił Zbrojnych, ze szczególnym uwzględnieniem doskonalenia sprawności mówienia. Artykuł podkreślił wkład systemu testowania językowego według STANAG 6001 w rozwój interoperacyjności z wojskami sojuszniczymi, przedstawiając główne fazy tego procesu. W końcowej części autorka podjęła próbę ustalenia, w jakim stopniu ten proces jest faktycznie osiągalny.

W zapewnieniu odpowiedniego stanu technicznego budynku w czasie jego użytkowania przydatna jest znajomość procesu starzenia budynku. W artykule jest przedstawiona propozycja modelu prognozy starzenia budynku mieszkalnego. Zaproponowany model PRRD określa zmiany właściwości użytkowych budynku w pełnym okresie jego użytkowania. Model uwzględnia okresy trwałości poszczególnych elementów składowych budynku. Do modelu dodatkowo wprowadzone zostały uzupełnienia uwzględniające intensywność zmian w obiekcie i w jego otoczeniu.

In order to ensure an adequate technical state of a building over the course of its use, familiarity with the building aging process is useful. The article presents the proposal of a model for predicting the aging of a residential building. The proposed PRRD model determines the performance characteristics of a building over the full period of its use. The model accounts for the life spans of individual building components. Additionally introduced in the model were supplements accounting for the intensity of changes in the building and its surroundings.

In today's business environment enterprises are trying to establish reorganization changes in their work and organization. It is necessary to structure the existing business to understand all enterprise functions, and change them in order to achieve the main enterprise objectives. To stay competitive under new conditions the external and internal factors should be assessed before restructuring of existing practices. The goal of this paper is to show how to put into practice the process of transition from Small-sized enterprise to Medium-sized enterprise category. For this purpose the existing company data that is stored in the ERP system should be transformed into knowledge. In this paper we consider the conditional "Metal Service" enterprise that produces various metal constructions and plans to produce load lifting equipment (jib cranes, overhead cranes, and additional equipment for existing cranes) for manufacturing enterprises that produce heavy products. The manufacturing capacities of enterprise are defined based on IDEF0 functional model created for each type of product. The simulation results received from these models enables to analyse new production processes, to estimate production time and route for all type of unit and yearly product release. In addition, after the Systematic Layout Planning (SLP) methodology and Relationship Matrix (RM) was applied to simulation results it became possible to calculate new manufacturing area, facilities layout and to assess the new production capacities.
