The quality of purchased parts is an important factor affecting the whole quality of the products, that how to grasp the size and trend of the defective rate in the warehouse-in inspection, becomes a meaningful theme in the quality control, through studying the modeling method of time series ARIMA model, applies variance analysis to the time series modeling, and carries out the variance analysi...

We apply morphological image processing for quality inspection of microfluidic chips. Based on a comparison of measured topographies with design data, we provide a coherent solution to four central tasks in the quality assessment of injection moulded polymer devices: determination of channel depth, identification of burrs, calculation of transcription accuracy, and detection of defective region...

Enlargement of quality requirements in metallurgical semi products used in cannon barrels production (forgings) has resulted in substantially increased number of defective products. The main issues are poor quality of plastic properties and yield point of processed materials. Careful analysis of forgings technology and adaptation of its constituent phases has not resulted in the quality enhance...

Unlike previous research, this study develops an integrated inventory model for controllable lead time with defective items, errors in inspection, and variable considering sustainability. The research investigates the effect of controlling capital investment setup cost. We assume that buyer receives a lot size may contain some items known probability. buyer’s inspector conducts 100% quality ins...

To ensure the delivery of high quality software, it is necessary to that all its artifacts function properly, which usually done by performing appropriate tests with limited resources. It therefore desirable identify defective so they can be corrected before testing process. So far, researchers have proposed various predictive models for this purpose. Such are typically trained on data represen...

Rd., Taipei City 106, Taiwan E-mail: [email protected] Abstract: This paper mainly focuses on the discussion of the best economic production quantity of process unreliable and defective items reproduce of the production system. In today'...

Preliminary studies have shown the superiority of convolutional neural networks (CNNs) compared to other network architectures for determining surface quality friction stir welds. In this paper, CNNs were employed detect cavities inside welds by evaluating inline measured process data. The aim was determine whether are suitable identifying defects exclusively, or if approach is transferable int...

Software quality has always been described as a poorly developed construct. Several reports and much evidence show clear problems related to software quality. This research empirically tests if ineffective implementation of knowledge management activities would be a reason behind possible existence of defective quality performance in the software industry. The main finding shows that knowledge ...

Phosphorene is receiving great research interests because of its peculiar physical properties. Nonetheless, no systematic studies on the transport properties modified due to defects have been performed. Here, we present the electronic band structure, defect formation energy and bias dependent transport property of various defective systems. We found that the defect formation energy is much less...
