Analysis Of Factors Causing Failure Mode For Automotive Hitch Control System Calibration In Agriculture Equipment, Setordji Yao Abotsi

Dissertations and Theses @ UNI

Traditionally, agricultural tractors have used hydro-mechanical draft control systems to mechanically sense implement draft. Technological development of low cost, reliable microprocessors has contributed to allowing greater flexibility in designing agricultural tractor control systems (Rutkowski & Welchens, 1986). To successfully control the depth of which an implement penetrates the ground, it has become imperative to incorporate a draft control system on agricultural tractors. The control system operates by responding to the draft load or force acting on the tractor. Increasing the draft load or force allows the implement to be raised and decreasing the draft load or force allows the implement …

An Experimental Cost Model For The Analysis Of Quality Cost In A Manufacturing Enterprise, Wallace Charles Carlson Jr.

Dissertations and Theses @ UNI

The intent of the study was to construct a quality cost model for manufacturing enterprises. A quality cost model provides a manufacturing enterprise with a cost structure which enables it to gauge and measure the efficiency and effectiveness of its management and processes. The quality cost model was specifically constructed to aid a manufacturing enterprise in establishing a quality cost system for its operations and activities and contains three distinct initial implementation or decision areas; the quality cost management decisions area, the quality cost system applications area, and the quality cost system utilization area.

The quality cost model was evaluated …
