One day when I leave, I swear I'm going to write a tell-all book about this industry. Until then, here's some condensed info.
To set the stage, this is a blue-collar industry, and what happens, so I've been told, is quite common in blue-collar industries. A lot of good ol' boy networking, people getting promoted who have no business being promoted, and as a consequence, a lot of corruption, ineptitude, and inefficiencies. The software in this space just flat out suck and anyone at a FAANG company would be appalled at how we write software. It's literally longshoremen trying to run software businesses.
On the other hand, as a terminal, it's very hard not to make money, so there's a lot of players, and unfortunately a lot of, at least shady deals.
I'm involved with a company that sells to terminals that don't have home-grown software systems. I don't have that much info on terminals that have their own software staff, however, there just isn't that much breakthroughs in the space. It's a conservative industry with a lot of money already, so there traditionally have been little incentive with high risks.
In addition to the aversion to risk, there's a lack of software product and engineering strategy to invest in optimization properly. One major vendor, I was told by a colleague did invest substantially, failed, and "it almost bought the entire company down." My company has dabbled before. We've had a couple of PhDs on staff. We even had a neighbor search solution like in the article developed. It worked in simulation and testing, and failed miserably in real life. The customer didn't take it, and we never had the vision to actually salvage anything from the effort.
There are a few vendors in this space, but again, the landscape is pretty sad. I know of one that are flat out frauds. They exist because the CEOs used to be in the industry and have credibility. They're still around because they're able to con non-technical terminal managers and string them along for a while. A few more maybe have 1 or 2 competent data scientists, but that's not enough. I've worked with one company that is good and is easily the most qualified, but they have never had the marketing and leadership to make themselves the billions they should be worth. They also simultaneously price themselves out of range for most terminals.
The industry is changing, though, because private equity has gotten involved in many companies. They have taken over some internal initiatives and basically dragged many of these good ol' boys against their will, or forced them out. They've also forced companies to partner with tech giants to address these issues. IMO, this is the only way we will see supply chain optimization revolutions any time soon.
