The Ops station on Voyager made more sense than on the Enterprise, though I still think it's odd that it's on the bridge at all. It would have made more sense if they had simply called Ops the science station which it really functions as more often than not. Of course, on Voyage, it seemed to overlap with Tuvok's security duties a bit and in at least one episode I've seen Paris do sensor scans from his station. The writers never seemed to really get it straight as to what station does what, I'm just surprised that they never had anybody at security or ops try and actually helm the ship at any point, or have they?
Except it doesn't really do much science. It manages the ship's sensors, but for the most part isn't telling those sensors what to do. Have you read the write-up in the old TNG Technical Manual? But yeah, the various science departments can request sensor time. Tactical and Flight Control can task higher-priority sensor scans. All of that still goes through the Ops programming, and the Ops Manager can manually override the automatics at any point, resolve conflicts, etc. There's more, but I won't transcribe the whole entry unless/until I know whether you're familiar with it.
As for your general assessment of Voyager, I agree. The premise wasn't so much flawed as compromised by not taking it far enough and taking enough risks, instead of making it more like TNG with the backdrop of being far from home. They really should have made it more serial and showing the Voyager looking more damaged as time goes on, systems not running optimally, and taking on a more hodge podge look as they adapt alien systems to the Voyager in order to keep it running. They also should have had more difficulty with communication since I'd imagine that not everybody in the Delta Quadrant utilized the same frequencies as the Alpha as their hailing frequencies. Then there's the matter of the universal translator always working perfectly even though you'd think that its algorithms would be based on Alpha Quadrant languages and would thus have to adapt, theoretically, Delta Quadrant languages that would, presumably, have evolved differently from the Alpha Quadrant.
All of that. All of that and more.
