A constraint programming approach to optimize coal

Dec 26, 2013A coal rail system is very complicated, especially where it consists of a single track. Most studies consider single track rail to be an NP-hard problem, and so needs special techniques to find solutions. A job shop scheduling problem is adapted and formulated using a constraint programming approach to produce global optimal solutions.

Milling Process, Defects, Equipment custompartnet

Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached to a platform inside the milling machine.
