Platforms are one of the most widely used services for sharing information by integrating multiple interacting systems into a network. The current platform integrates these systems with tight coupling to meet a new level of customer requirements.With the rapid increase in the information traffic along the global supply chain, many companies in the aviation industry have been confronting with these issues of processing and storing data within and across the enterprise. More and more companies are adopting an Enterprise Resource Planning (ERP) system which consists of a set of fully integrated modules to support a company's business processes that run from a single database. Nowadays, the database structure in the ERP system is customized for each company by external vendors. The aviation industry is characterized by a large network and long supply chains with the few Original Equipment Manufacturers (OEMs) and many suppliers (Tier 1, Tier 2, Tier 3). Individually created databases with own terms within the company make an intercompany exchange only possible with high effort.In this paper, we show how to model and simulate ordering processes across different supply chain tiers in the aviation industry rapidly to validate the use cases concerning the communication structure during a requirements-based engineering process.enaircraft supply chainaviationdatabase systemfederationrequirements engineeringsimulationSimulation of Ordering Processes across different Supply Chain Tiers in the Aviation IndustryConference Paper10.1109/SysCon53536.2022.9773906Other
