Build a IoT Simulation for Accounting Project

First of all, I need production process simulation. Then we need to obtain the data for the accounting department. Then, we should determine the warehouses on the map and transfer the products between these points and use the data we have obtained for the accounting department. At this point, we have to perform a stock transfer between multiple mobile vehicles and warehouses. As a result, I need two different virtual simulations, namely production and stock transfer. The more machines we can add to the production process, the better.
