“…Varied inspection makes use of fuzzy controllers to read inputs and to calculate how much inspection to perform, known as 'inspection intensity'. Previous research [7], [6] showed that varied inspection could be used to reduce work-inprocess and manufacturing lead time respectively. Figures 1 and 2 show the respective results [7], [6].…”

“…Each subsystem was measured for its manufacturing lead time, work-inprocess, and production surplus. Previous research in varied inspection [6], [7] showed that this type of inspection plan could reduce work-in-process and manufacturing lead time for the benefit of the manufacturer, and could be applied to the mass customisation environment, as mass customisation requires flexible inspection tools and methods.…”

“…Similar research to this was performed by He and Chang [9], where inspection was focused on product key quality characteristics (PKQCs), as these characteristics held the most value in the product. Other previous research [6], [7] showed that a reduction in inspection in a single-station manufacturing cell could reduce work-in-process and manufacturing lead time, where parameters used to reduce inspection were centred on the defect rate. Reduced inspection could also reduce inspection costs; a study performed by White et al [10] showed that reducing inspection on a fin gripper reduced appraisal costs and production time, as a selection algorithm was only used to inspect the important fin gripper features.…”

Varied inspection is an on-line dynamic inspection method in which the amount of inspection performed fluctuates, based on production needs. A two-level control architecture of fuzzy controllers was used to perform varied inspection. The research was the application of varied inspection into three manufacturing subsystems: transfer lines, assembly, and disassembly. The results from each simulation showed that varied inspection could be used to meet production cycle aims while reducing manufacturing lead time. Varied inspection was compared with 100 per cent inspection to determine the significance of varied inspection compared with traditional quality control methods. OPSOMMING Gevarieerde inspeksies is 'n aanlyn dinamiese inspeksie metode waar die aantal inspeksies wat uitgevoer word wissel op grond van die produksiebehoeftes. 'n Tweevlakkige beheer argitektuur van wasige beheerders is gebruik om die gevarieerde inspeksie uit te voer. Hierdie navorsing ondersoek gevarieerde inspeksies in drie vervaardigingsubstelsels: oordraglyne, monteerwerk, en demonteerwerk. Die uitslae van die simulasie toon dat die gevarieerde inspeksie effektief was om die doeleindes van die produksie siklus te verwesenlik. Die navorsing dra ook by tot die vermindering van die vervaardiging leityd. Gevarieerde inspeksie is ook met 100 per sent inspeksie vergelyk, om die invloed van gevarieerde inspeksie in teenstelling met tradisionele gehaltebestuurmetodes te bepaal.
