In this paper, the variation transmission model is introduced to build the key quality characteristics identifying model in multistage manufacturing process. Then the PLSR (Partial Least Squares Regression) method is used to solve the multicollinearity problem of the quality characteristics, make model analyzing and identify the key quality characteristics. At last, the aircraft parts manufactu...

In this paper we present a novel approach to modelling a manufacturing process that allows one to learn about causal mechanisms of manufacturing defects through a Process Modelling and Executable Bayesian Network (PMEBN). The method combines probabilistic reasoning with time dependent parameters which are of crucial interest to quality control in manufacturing environments. We demonstrate the c...

resistance spot welding is an important manufacturing process in the automotive industry for assembling bodies. the quality and strength of the welds and, by extension, the body is mainly defined by the quality of the weld nuggets. the most effective parameters in this process are sheet material, geometry of electrodes, electrode force, current intensity, welding time and sheet thickness. the p...

Manufacturing innovations are technologies and activities that improve and change the level of capacity, performance and quality in manufacturing permanently or over time. This policy brief explores the role of manufacturing innovations in different Nordic contexts, their link with production relocation decisions and performance implications. Manufacturing innovations are analyzed in terms of f...

Imperfections due to the manufacturing process and in its resources areresponsible for the deterioration of functional characteristics and as a consequence, theproduct quality. In order to ensure a certain quality level, the tolerance synthesis tries todetermine admissible limits of workpiece and assembly characteristics. Tolerance synthesisor tolerance allocation, which belongs...

Networked manufacturing is an advanced manufacturing technology, and efficient customer relationship management is critical for networked manufacturing’s resource allocation and scheduling. Evaluation of customer relationship management’s performance under networked manufacturing and effective optimization measures are preconditions for improving on CRM’s performance. Development process’s qual...

Quality by Design (QbD) refers to a holistic approach towards drug development. QbD has become the answer to assist both industry and FDA to move towards a more scientific, risk based, holistic and proactive approach to pharmaceutical development. The concept promotes industry’s understanding of the product and manufacturing process starting with product development, basically building quality ...

The purpose of this paper is to provide the software engineer with tools from the field of manufacturing as an aid to improving software process and product quality. Process involves classical manufacturing methods, such as statistical quality control applied to product testing, which is designed to monitor and correct the process when the process yields product quality that fails to meet speci...
