Improving Supply Chain Reliability Using Simultion Modeling

In today's world, where there are many external factors affecting logistics systems, supply chain reliability is a key component. Disruptions, be it natural disasters, market fluctuations or logistical problems, can seriously affect operations, customer satisfaction and ultimately the bottom line. Therefore, this study aims to introduce an innovative paradigm to improve supply chain reliability through the use of simulation modeling. This work aims to identify factors that reduce supply chain reliability through data collection, simulation and scenario analysis. By simulating various scenarios ranging from demand spikes to chain failures, logistics stakeholders will be able to prevent problems, test strategies to solve them, and strengthen the supply chain against unexpected failures in advance. The purpose of this thesis is to study the reliability of the supply chain, and in the development of a simulation model on which optimization methods will be applied in order to improve its reliability and resilience to external factors. In order to achieve the objectives of this work, the following list of tasks will be accomplished: - Studying the concept of supply chains and their structure; - Analyzing the reliability of chains and the factors affecting it; - Reviewing the concepts of reliability management; - Developing a simulated supply chain of spare parts to airports and analyzing its performance on the reliability side; - Application of methods to improve the reliability of this model. The object of the study is supply chain reliability. The subject of the study is simulation modeling which is used to evaluate and improve the reliability of chains. This paper consists of introduction, three chapters, conclusion and list of references. In the first chapter, the concept of supply chains, their structure, concepts and features of supply chain management were discussed. In this chapter, literature analysis, definitions and scientific viewpoints were analyzed. The second chapter deals with supply chain reliability. It provides ways to improve it, the main factors affecting it, analyzed the methods of management and considered AnyLogic simulation program as a way to improve reliability. The third chapter is devoted to the construction of supply chain simulation model, as well as experiments, runs and statistics collection. In conclusion, the main conclusions of the research are presented, as well as conclusions regarding its practical part. For writing this thesis were applied methods of empirical and theoretical analysis, comparison and other mathematical and statistical methods. The sources were foreign and domestic literature, textbooks, books, scientific articles.
