Purpose: The aim of the article is to analyze the operation of company X in the context of logistic customer service in practice. Design/methodology/approach: The idea of the work is to present the theoretical part of customer service and compare it to logistic customer service in practice. It also includes comparisons of practical solutions of company X to theoretical requirements. Findings: The research issue discussed in the article was a survey. Its purpose is to present customer service in Patrick's Day in company X. 81 people of different genders and age groups responded anonymously to the survey questions 15- >60 years. General knowledge of the logistics industry and responses from opinion makers were taken into account. The responses of the surveyed people were presented graphically along with their descriptions. Research limitations/implications: The practical part is intended to reflect the actual compliance of company X with the imposed rules. The Logistics Customer Service Principles were created to ensure a consistent and effective approach to customer service in the context of logistics. Practical implications: The type of customer service strategy depends on the specific goals and needs of a given business. The essence of logistic customer service is the effective management of the flow of products and services from the place of production to the place of consumption in order to meet customer needs. Logistics customer service covers many aspects, such as planning, controlling and monitoring the flow of goods, inventory management, transport, warehousing and coordination of activities between various links in the supply chain. Social implications: Customer service also means the ability to accept customer opinions and comments with an open mind. Customers should be able to express their opinions and complaints and then respond effectively. Originality/value: The article draws attention to the importance of a non-routine approach to the dynamics of opportunities. This is important for management as a scientific discipline, but also for managers, which indicates various possible development paths.

The paper presents the problem of optimal shaping of the H-bar cross-section of a steel arch that ensures minimal mass. Nineteen combinations of nine basic load states are considered simultaneously in the problem formulation. The optimal shaping task is formulated as a control theory problem within the formal structure of the maximum Pontriagin’s principle. Since the ranges of constraint activity defining the control structure are a priori unknown and must be determined numerically, assuming the proper control structure plays a key role in the task solution. The main achievement of the present work is the determination of a solution of the multi-decision and multi-constraint optimization problem of the arch constituting a primary structural system of the existing building assuring the reduction of the structure mass up to 42%. In addition, the impact of the assumed state constraint value on the solution structure is examined.

This paper is a continuation of the first part [7] where basic relations and derivatives related to the sensitivity analysis of the standard 3D beam element have been derived. This part presents the sensitivity analysis of dynamic response of a flat frame using the Direct Differentiation Method for harmonic and seismic excitations separately. Harmonic excitations are typicaly found if some equipment is placed on the stories of industrial buildings. In that case the practical benefit of determining the structure response and its derivatives allows to determine, for example, the vibration comfort of staff and determine the impact of particular structural parameters on the level of comfort. With regard to seismic excitations, determining the response of a structure and its derivatives allows to determine the level of impact of individual parameters on the response.

Niniejszy tekst jest kontynuacją części pierwszej [7], w której wyprowadzono podstawowe relacje i pochodne związane z analizą wrażliwości standardowego elementu belkowego 3D. W niniejszym artykule przedstawiono analizę wrażliwości odpowiedzi dynamicznej ramy płaskiej metodą bezpośrednią przy wymuszeniach osobno harmonicznych oraz sejsmicznych. Rozważane zadanie jest liniowe. Wymuszenia harmoniczne są typowe przy lokalizacji rozmaitych urządzeń na stropach budynków przemysłowych. Praktyczna strona wyznaczenia odpowiedzi konstrukcji i jej pochodnych w takich sytuacjach pozawala określić np. komfort wibracyjny osób znajdujących się na konstrukcji oraz określić wpływ poszczególnych parametrów konstrukcyjnych na poziom tego komfortu. W odniesieniu do wymuszeń sejsmicznych wyznaczenie odpowiedzi konstrukcji oraz jej pochodnych pozwala rozstrzygnąć skalę wpływu poszczególnych parametrów na odpowiedź.

This paper presents a sensitivity analysis related to the solution of a stationary, linear system of second order equations of motion obtained by the Finite Element Method. The Direct Differentiation Method was presented in this paper. The essence of this method is the explicit differentiation of the system of equations with respect to parameters. As a result, derivatives of vectors and matrices are obtained. The necessary material derivatives of vectors and matrices associated with the simplest 3D beam element are presented. Sensitivity analysis consists in searching for changes in physical quantities in relation to selected parameters. Ultimately, the sensitivity analysis comes down to calculating derivatives of specific functions with respect to parameters. Real and continuous design variables are considered.

Analiza wrażliwości polega na poszukiwaniu zmian wielkości fizycznych względem wybranych parametrów. Sprowadza się ona do obliczania pochodnych określonych funkcji. W pracy przedstawiono analizę wrażliwości rozwiązania stacjonarnego, liniowego układu równań ruchu drugiego rzędu otrzymanego metodą elementów skończonych. Przedstawiono metodę bezpośrednią analizy wrażliwości. Polega ona na bezpośrednim zróżniczkowaniu równań względem parametrów. W rezultacie uzyskano pochodne wektorów i macierzy. Przedstawiono niezbędne pochodne materialne wektorów i macierzy związanych z najprostszym elementem belki 3D. Rozpatrywano rzeczywiste i ciągłe zmienne projektowe.
