Ukraine is experiencing challenging economic instability that is affecting various economic sectors. Due to military actions and infrastructure destruction, there is an urgent need for rapid and effective reconstruction. Network planning methods help optimise resources and minimise costs, which is particularly relevant in conditions of limited funding. These methods enable the coordination of numerous projects, ensure their timely completion, and contribute to better synchronization between different project stages, reducing the likelihood of errors and delays. This study aimed to analyse network planning methods in project management, examine their key advantages and disadvantages, and justify the feasibility of using different project management software in conditions of economic instability and uncertainty. The article presented an analysis of two primary network planning methods – Program Evaluation and Review Technique (PERT) and Critical Path Method (CPM). A network diagram for the reconstruction of a production unit was developed. It has been proven that precise planning, resource optimisation, and effective risk management enhance the overall efficiency of project implementation, which is crucial for improving the competitiveness of Ukrainian enterprises. The study confirmed that the relevance of PERT and CPM in modern project management is due to their ability to ensure efficient planning, control, and resource management. The development of information technologies has opened new opportunities for the implementation of automated project management systems. It has been established that network planning methods can be easily integrated with modern software solutions, thereby increasing project management efficiency. An overview of key project management tools was conducted, and their applicability for network diagram construction was examined. The use of network planning methods in Ukraine is essential for effective project management, resource optimization, and enhancing the country’s competitiveness
