- dfc 13y agoI just started to skim your thesis so I apologize if this is covered somewhere. Is it commonly understood that route optimizations for maritime transport are equivalent to automobile transport?
- mck- 13y agoMaritime transport, specifically Tramp Ship Scheduling, is very similar to a taxi operation. Taxi logistics are known in literature as Pickup and Delivery Problems with Time Windows (PDPTW) -- which is an advanced type of VRPTW -- which, in turn, is more complex than the classic TSP. To answer your question: mathematically, Tramp Shipping is a more advanced type of PDPTW, so they are almost equivalent. We will support PDPTW on our API soon, but what I present here with Routific is but a subset of what I cover in my thesis: Multi-Depot Capacitated Vehicle Routing Problem with Time Windows and Heterogenous Fleet with Shift Constraints (MDCVRPTWHFS -- so glad I did not pursue academia) P.S.: in my thesis I also optimize the sailing speed of the ships, which -- as my thesis goes -- can save millions a year on top of an already optimized shipping fleet. The cubic relation between sailing speed and fuel consumption does not hold for vehicles on the road though.
- troels 13y agoYou should put a link to a small bio of you somewhere on the front page. You clearly know what you're doing, but the copy on the page doesn't convey this clearly, I think. Edit: OK, scratch that. I just realised that I was looking at a sub section of the site, not the actual front page. Although it probably wouldn't hurt to flash your credentials.
