Eksploatacja i Niezawodność

2023

Vol. 25, no. 1

art. no. 1

The article presents the issue of assessing the effectiveness of the implementation of a logistics process with the use of a simulation model and queue theory. The process that has been analyzed is the process of goods’ delivery at the technical object. Firstly, a literature review was carried out. Next, the authors described the process using the QT (Queueing Theory). This was possible due to the fact that QT is widely used in the analysis of systems as well as the assessment of their effectiveness, maintenance, and reliability. The description, characteristics and graphic presentation of the system in which the process is carried out have been included in the study too. Then the process was implemented in the computer simulation environment. Simulations were carried out and four variants of the system operation were analyzed. The comparison of the operating parameters of the system for each variant allowed for a detailed analysis of its operation and the influence of selected factors on the implementation of the process as well as it effectiveness or reliability.

W pracy przedstawiono punkt widzenia zagadnień niezawodności podmiotów tworzenia (badań, projektowania i wytwarzania) oraz eksploatacji obiektów technicznych, a także niezawodności tych obiektów, przez pryzmat etycznych, poznawczych i estetycznych kategorii. Scharakteryzowano relacje między wybranymi kategoriami a niezawodnością człowieka. Opisano zagadnienia: zawodność podmiotów (człowieka – osób) wyróżnionych procesów a niezawodność obiektów technicznych. Dokonano rozważań w tym zakresie.

In this paper the author presents the point of view of reliability problems of subjects of creation (researches, designing and production) and exploitation of technical objects, and reliability of these objects, through ethical, cognitive and aesthetic categories. The relations between selected categories and reliability of human are characterized in the paper. Problems: unreliability of subjects ( human – individuals of distinguished processes and reliability of technical are being described. Considerations are made in this sphere. Their ending is constituted by a conclusion.
