Various embodiments provide techniques for analyzing resources based on a set of rules to determine problems that may occur during a product development cycle. The rubber kneading machine includes two horizontal rolls closely disposed vertically, decelerators and variable speed motors rotating the rolls at different speeds, and a screw extruder supplying a rubber lump fed into a hopper at a proximal end to the rolls. Said rotor is rotatably supported on the at least one bearing portion relative to said stator.
