[QUOTE="curiousbrain, post: 954583, member: 31608"] Few things in life are absolute, from any side. Read [URL="http://en.wikipedia.org/wiki/Industrial_engineering"]Industrial engineering[/URL] and [URL="http://en.wikipedia.org/wiki/Value_engineering"]Value engineering[/URL]; then, read some of the driver horror stories, and talk to some of the drivers in your hub/center, or some of the drivers on here. The point I am trying to make is that mathematical models are great for reducing cost in an absolute sense, but it is very difficult (as far as I can tell, anyway) to account for the constant decisions and unforeseeable circumstances that happen in the reality of life. One might even want to read about [URL="http://en.wikipedia.org/wiki/Engineering_economics"]Engineering economics[/URL] [I]and[/I] related topics, and consider them under the context of trying to model real world, hard-time logistics such as happens at UPS; specifically, approximate solutions to problems which cannot be solved exactly. The margin of error could be large or small, in either direction. I would end by making the point (perhaps out of ignorance of how IE actually works, as I don't work there and never have) that, in the context of the economic system that, more often than not, puts profit first, if IE did not create value, no company would have an IE department; thus, it follows that IE does create value. It may, however, take a special kind of person who can discount the sacrifice required for that creation of value. In the vein of follow the money, I say go for it; if you don't do it, someone else will and they will never give you a second thought. [/QUOTE]
