The production planning process is the creation of a plan with steps such as which goods will be produced and how much will be produced, when will be produced, what will be the capacity need, determination of the necessary machines and workforce, and the most appropriate job assignment by bringing the appropriate jobs and personnel to the machines. Today, many companies use various methods for production planning, which we divide into two as long-term planning and short-term planning. In this study, it is aimed to emphasize the importance of production planning and to do business planning correctly. The increasing competitive environment has made it necessary to plan the production correctly, which is the most important place for a company. The study was evaluated by making short-term production planning for Küçükpazarlı Aviation company, which produces machining in the aviation sector in the mainland. The current works and the qualifications of production in the enterprise were determined, and the classical method, Gantt method and Johnson method were tried. Three methods were examined and the Gantt method was chosen as the most suitable scheduling method among the methods. The aim of this study is to ensure timely delivery performance by making the right business plan of the company. The results obtained were compared and analyzed with the current classical situation in the enterprise. As a result, more successful results of the applied Gantt method in production planning than the current classical method were obtained and examined KW - Scheduling KW - Production Planning KW - Workloading CR - Alptekin, Ü.
