Taguchi's emphasis on instilling quality at the design stage has been important in a number of situations and deserves careful attention. His specific robust design approach has yielded good results in many instances, but recent studies indicate that more classical designs can serve the same purposes-sometimes, at least, doing so more efficiently, albeit less understandably for the technically ...

The ever-increasing complexity of software systems makes them hard to comprehend, predict and tune due to emergent properties and non-deterministic behaviour. Complexity arises from the size of software systems and the wide variety of possible operating environments: the increasing choice of platforms and communication policies leads to ever more complex performance characteristics. In addition...

Cloud Computing is an emerging technology for processing and storing very large amounts of data. Sometimes, anomalies and defects affect a part of the Cloud infrastructure, resulting in a degradation in Cloud performance. This work uses the Taguchi method for the design of experiments to present a methodology for identifying the relationships between the various configuration parameters that af...

The challenge of recent machining industries is reduce lead time and increase production rate in order to maintain their competitiveness. This paper investigates the machinability of mild steel in turning process perform on conventional lathe machine. Twoparameters like tool rake angle and feed are varied to investigate their effect on material removal rate. An attempt has been made to model th...

The work desires: i) to determine the optimum level of batch size in bottleneck facility and ii) to analyze the effect of common components on work-in-process (WIP) level and cycle time in a multistage production system under uncertainties. The uncertainty is created by machine breakdown and quality variation. Few simulation models are developed based on a live case from a company. The models a...

In k 2 experimental design, the classical fractional factorial designs, the Plackett-Burman designs and the Taguchi orthogonal-array designs all require, with few exceptions, n 2 test conditions, for some k n ≤ . Tsao and Wibowo (2005) pointed out that when only m of the k 2 effects/interactions are non-zero, only m test conditions are required for their estimation. Given the identities of m pr...

This investigation proposes a grey-based Taguchi method to solve the multi-response problems. The grey-based Taguchi method is based on the Taguchi’s design of experimental method, and adopts grey relational analysis (GRA) to transfer multiresponse problems into single-response problems. In this investigation, an attempt has been made to optimize the drilling process parameters considering weig...

Path planning for a robot-assisted surface finishing system with an active torque controller is presented in this paper. We utilize a dexterous manipulator to attain the desired position and orientation in three-dimensional space during finishing processes. A single-axis active controller consists of a dc motor and a software observer is attached to the robot wrist and used to actuate a pneumat...

In the present work CO2 continuous laser welding process was successfully applied and optimized for joining a dissimilar AISI 316 stainless steel and AISI 1009 low carbon steel plates. Laser power, welding speed, and defocusing distance combinations were carefully selected with the objective of producing welded joint with complete penetration, minimum fusion zone size and acceptable welding pro...

The two major challenges that industries are facing today are continuous improvement in productivity and quality of the product. An alternative to the Classical and Taguchi experimental design is the lesser known but much simpler Shainin DOE approach. Shainin methods refer to a collection of principles, which make up the framework of a continually evolving approach to quality. Bosch Production ...
