Solution Methodology

The placement of surface mount components is a time consuming and critical task in the assembly of surface mount Printed Circuit Boards (PCBs). The focus of this research was the identification of “near optimal” solutions for the placement sequence identification problem. The factors considered include the placement machine and the specific PCB, the feeder space available, the need for tooling and nozzle changes, and the actual traveling path of the placement head. Expert (or knowledge based) systems were used as the solution method for this problem. The system developed can cope with single PCBs, panels, 180 deg offset boards (panels), and multiple PCB batches. The prototype knowledge based system developed in this research identifies solutions in (almost) realtime.

Abstract. Research demonstrates that the negative relationship between Openness to Experience and conservatism is heightened among the informed. We extend this literature using national survey data (Study 1; N = 13,203) and data from students (Study 2; N = 311). As predicted, education – a correlate of political sophistication – strengthened the negative relationship between Openness and conservatism (Study 1). Study 2 employed a knowledge-based measure of political sophistication to show that the Openness × Political Sophistication interaction was restricted to the Openness aspect of Openness. These studies demonstrate that knowledge helps people align their ideology with their personality, but that the Openness × Political Sophistication interaction is specific to one aspect of Openness – nuances that are overlooked in the literature.
