In the context of stochastic uncertainty and the increasing complexity of logistics processes in the retail sector, managers face a problem in obtaining accurate forecasts for the dynamics of changes in key business performance indicators. The purpose of the present work is to assess the impact of risk events and unstable conditions on the level of quality of supply chain services and economic indicators of the retail trade network. Using the anyLogistix software tool, a simulation model was constructed that allows assessing operational risks and their impact on key indicators of the supply chain using the bullwhip effect. Besides, a statistical model of the impact of the ripple effect in the event of failures caused by the occurrence of a man-made risk event and the shutdown of production of one of the suppliers on the financial, customer, and operational performance indicators of the supply chain of grocery retail. The results obtained show that the main factors of changes in the supply chain are operational risks associated with fluctuations in demand and order execution time by the distribution center. With a sufficiently high level of occurrence, their impact on productivity and quality of service is low because they can be eliminated in a short time. The simulation results show that the most tangible risks for the food retail supply chain are supply chain failures, whose consequences require significant coordinating efforts and longer recovery times, as well as additional investments. For example, events, such as a fire in one distribution center and the shutdown of production for 1 week of one of the suppliers of dairy products will lead to the loss of USD 181.75 million by the grocery retailer, which is 3% of the expected revenue. We believe that risk management in supply chains is becoming increasingly complex, and to make effective managerial decisions, it is necessary to constantly improve the tools that combine analytical and optimization methods, as well as simulation modeling.
In the conditions of existing threats —the lack of full-fledged travel mobility, the growth of air fares due to the complication of flight logistics and the duration of air travel, currency risks — the opportunities for the development of outbound and inbound tourism are limited. It is necessary to reorient the tourism business to the development and support of domestic tourism with the fragmented development of the incoming flow from neutral and friendly countries. To promote the development of various types of domestic tourism in demand by Russian citizens. To develop and implement a number of management solutions for leveling the emerging threats to the tourism sector. The object of the article is management decisions in the field of tourism in the context of international sanctions. The purpose of the article is to analyze possible measures to stabilize it in the face of sanctions by the international community. The tasks are to study the state of the tourism industry and hospitality; identification of risks posed to the industry by the imposition of sanctions; determination of the main types of instruments that mitigate external threats and consideration of the possibility of applying the proposed anti-crisis measures. In the article used common methods of research, such as observation, systematization and synthesis of collected theoretical and practical material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
