This tool was developed for an Aircraft manufacturing unit. User is presented with multiple problems which he might face e.g. for a Project Manager who has to deliver number of parts in a limited time format. He/She can do this by either manufacturing parts in-house, by procuring from elsewhere or using a combination of both. Now based on delivery timelines, user needs to find out an optimum scenario on what can be the best case. An output is shown in terms of costs to cover this project.
