Planning and Scheduling is a domain where Lisp has historically seen a lot of applications. For example the planner for the use of the Hubble Space Telescope (and many other telescopes in space and on earth) was originally developed on TI Lisp Machines and later ported to Common Lisp on other platforms. Generally there were a bunch of Lisp-based planners for space operations (like payload planning for Space Shuttles or planner for mars operations). There were a bunch of Lisp-based planner application in military - with the most famous being the DART system - which was used for planning the logistics for the first gulf war and saved more money that the US had ever invested in AI research up to that point in the past 30 years. With field-deployed Common Lisp applications in the middle-east, talking to remote servers. https://en.wikipedia.org/wiki/Dynamic_Analysis_and_Replanning_Tool https://en.wikipedia.org/wiki/Dynamic_Analysis_and_Replannin...
