I like that it allows users to perform simulations of different scenarios for various projects, with varying inputs/materials. The software is easy enough to use without having any experience or training in this area! It would be nice if there were more materials available (aside from just rock). This can sometimes make finding what you need difficult, but not impossible - we've been able to figure out some things by doing research ourselves online instead of relying solely upon Haulsim's support team. We are using haulsim as part of our feasibility analysis process when considering future mines / sites; it helps us predict how much material will come offsite vs. being processed at-mine so far into planning stages.
