For a client proposing installations of equipments at sea, I developed a tools which allowed him to have in a very reactive way and without going through the planning tools (MS project, primavera, ...) an analysis of different scenarios. The parameters to evolve simultaneously were the production rhythm (in blue on the graph) and the equipment installation rate that can vary depending on the weather (in black on the graph). The rhythms of delivery and preparation of the products on site are fixed in this example (in gray and mauve on the chart)
