Appropriate description and implementation of internal part traceability in manufacturing is a complex task. Accurate and real-time traceability from a part to a manufacture, storage, or transport issue is essential to efficient and high-quality operations. With the increasing amount of machine status and product quality information coming from the manufacturing lines, a question arises. When t...

Wafer slicing is a complex manufacturing process, complicating efforts to monitor process stability and quality control effectively. This study discusses and develops a manufacturing quality yield model for forecasting 12 in. silicon wafer slicing based on the Analytic Hierarchy Process (AHP) framework. Decision Makers can select evaluation outcomes to identify the most precise machine. Additio...

www.pharmtech.com nalytical method development is a critical part of the drug development process. Analytical methods are used to check the quality of materials that will be used in clinical trials. As drug development progresses toward registration, these and other methods are used to generate information that will enable quality to be designed into the manufacturing processes of drug substanc...

The optimum fermentation times of black tea manufactured by two systems of Orthodox and CTC (cut, tear & curl) were investigated by measuring the quality parameters of black tea, like: theaflavin, thearubigin, highly  polymerized substances and total liquid colour during the fermentation stage. Optimum fermentation times from the beginning of fermentation were determined to be 60 min and 15...

This paper develops a quality estimation method with the application of fuzzy hierarchical clustering. Quality estimation is essential to quality control and quality improvement as a precise estimation can promote a right decision-making in order to help better quality control. Normally the quality of finished products in manufacturing system can be differentiated by quality standards. In the r...

This paper is related to textile industry especially to Yarn manufacturing process. Textile is one of the biggest manufacturing industries in India.Defects rate of product plays a very important role for the improvement of yield and financial conditions of any company. Actually defects rate causes a direct effect on the profit margin of the product and decrease the quality cost during the manuf...

This paper presents SimBuilder, a simulation system incorporating environmental and quality concerns into a traditional manufacturing simulation environment. These simulations can be used to generate a complete material balance around a particular manufacturing process and can be made available to design engineers to aid in life cycle design assessments. An example developed for the filament-wi...

It has been proved that process capability indices provide very efficient measures of the capability of processes from many different perspectives. These indices have been widely used in the manufacturing industry for measuring process reproduction capability according to manufacturing specifications. In the past few years, univariate capability indices have been introduced and used to characte...

In the manufacturing industry, product quality has become a key factor in determining a firm’s success or failure in the global marketplace. Advanced, highly reliable manufacturing methods have made it possible to achieve very high standards of product quality. As a result, more and more firms are making product quality a keystone of their competitive strategy. However, the improvement of produ...
