A Comparison Study of Inspector's Performance between Regular and Complex Tasks
This research was to study a comparison of inspector’s performance between regular and complex visual inspection task. Visual task was simulated on DVD read control circuit. Inspection task was performed by using computer. Subjects were 10 undergraduate randomly selected and test for 20/20. Then, subjects were divided into two groups, five for regular inspection (control group) and five for complex inspection (treatment group) tasks. Result was showed that performance on regular and complex inspectors was significantly difference at the level of 0.05. Inspector performance on regular inspection was showed high percentage on defects detected by using equal time to complex inspection. This would be indicated that inspector performance was affected by visual inspection task. Keywords—Visual inspection task, Regular and complex task.
The evaluation of the competency perception of inspectors in using new instructional technology
Abstract The purpose of this study is to find out the evaluation of inspectors in regards to their competency perceptions towards the use of new instructional technologies. This is a qualitative model research. The target population of this study consisted of 25 inspectors serving within the borders of TRNC in 2011. Data was collected by an “interview form” developed by the researcher. The interview form consisted of 6 items. Content analyze, frequency (f) and percentage (%) techniques were used to analyze the data. This research pointed out that: “concerns on falling behind the teacher”, “training needs”, “decreasing training support within the years” and “non existing policy on IT support” are critical factors affecting an inspector's competency perceptions in using new instructional technologies.
An empirical study of hybrid inspection systems and allocation of inspection functions
With the demand for zero-defect products and the requirement of shorter lead-time production, designs of inspection systems have changed from using sampling inspection and human inspectors to 100% inspection and automated inspection systems. Unfortunately, automated inspection systems usually cannot meet the required performance without some human intervention. The objectives of this research are to demonstrate the feasibility of hybrid inspection systems, to compare these systems with the unaided human system and unaided automated inspection systems, and to develop a framework to allocate humans and computers in an inspection system in order to achieve the best system performance. This research found that a hybrid inspection system had better performance than either human inspection or entirely automated inspection systems. A proposed function allocation procedure was found to be feasible.
