A new heuristic solution procedure for the solution of the rectilinear Steiner problem is proposed. The procedure is based on an innovative neighborhood structure that is explored using a pseudo-greedy approach. The probabilistic rules designed to induce search diversification are based on move attributes derived from the neighborhood structure. A Taguchi design of experiments is used to find t...

In this study, the problem of giving priority to two or more quality chracteristics faced while applying Taguchi Method on multiresponse problems is studied. It was based upon Tong et al.(1997)’s approach on assignment of weights derived from individual experiences. Instead of prioritizing by personal judgments, Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP) methods were us...

In this study, the Taguchi method is used to find the optimal process parameters for an injection moulding machine that was used to produce a consumer product (plastic tray) from polypropylene (PP) plastic material. An orthogonal array (OA), main effect, signal-to-noise (S/N) ratio, and analysis of variance (ANOVA) were employed to investigate the bending characteristics of the tray under a con...

WPAN using IEEE 802.15.4 protcol operated in non beaconing mode an attempt has made to find out the most significant factor of defacto parameters enhance performance by minimizing energy consumption and network lifetime Wireless Personal Area Networks(WPAN). The factors include Buffer size, Beacon Interval, Back-off-transmission ideal impact on QoS metrics protocol. A Design experiments have be...

in this study, the application of gray relational analysis (gra) and taguchi method in multi-criteria process parameters selection of turning operation has been investigated. the process responses under study are material removal rate (mrr) and surface roughness (sr); in turn, the input parameters include cutting speed, feed rate, depth of cut and nose radius of the cutting tool. the proposed a...

Calibrations to existing cost of doing business in space indicate that to establish human presence on the Moon and Mars with the Space Exploration Initiative (SEI) will require resources, felt by many, to be more than the national budget can afford. In order for SEI to succeed, we must actually design and build space systems at lower cost this time, even with tremendous increases in quality and...
