“…Thus, uncertainty in the GRG can be handled by the fuzzy logic approach, and thereby, a fuzzy reasoning of multiple performance characteristics has been developed and is referred as grey-fuzzy systems (Abhishek et al , 2013). The optimisation procedure can be performed on a single grey-fuzzy reasoning grade (GFRG) rather than various multiple performance characteristics (Satheesh and Dhas, 2014). The GFRG is integrated with Taguchi’s method to optimisation of process parameters based on multiple responses (Rajmohan et al , 2013; Abhishek et al , 2016).…”

Purpose The purpose of this paper is to optimise the process parameters, namely, point angle, spindle speed and feed rate in the drilling of glass-reinforced stainless steel mesh polymer (GRSSMP) composites using grey relational fuzzy logic. Design/methodology/approach Based on the full factorial design, the experiments were conducted. The output responses considered are thrust force, torque, delamination and diameter deviation. Based on responses, the optimised process parameter was selected using grey-fuzzy reasoning analysis (GFRA). Findings The percentage contribution of the drilling parameters is analysed using analysis of variance (ANOVA), and the result shows that feed rate is the most influential factor in the drilling of GRSSMP composites. Research limitations/implications The optimised drilling parameters have been used for drilling of polymer composites in the production industry. Originality/value Optimisation of process parameters during the drilling of GRSSMP composites using GFRA has not been performed previously.

“…Ketika berhadapan dengan persoalan multirespon, penyelesaian secara parsial untuk masing-masing respon menjadi tidak efektif dan menimbulkan kombinasi level parameter optimal yang tidak konsisten antar respon dikarenakan tidak semua respon memiliki karakteristik yang sama (Kutner, dkk., 2014). Dengan demikian dibutuhkan perhitungan statistika untuk mengetahui kombinasi yang tepat dalam kasus perancangan percobaan multirespon (Sathees dan Dhas 2013).…”

The main functions of tire are to withstand the vehicle’s load, continue the steering function and control the vehicle’s direction, transmit the driving force and vehicle’s braking on the road surface and reduce shock vibrations from the road surface. Therefore, optimal tire selection is something that needs to be considered for driving perfection. Taguchi methods is one of experimental design methods that is often used because of considerations of effectiveness and efficiency. However, Taguchi methods only can be used to solve a single response optimization problem. When dealing with multi-response problems, the responses are analyzed separately. This study aims to optimize Taguchi design using VIKOR method in production of car tires. The experimental design and responses used in this study were derived from car tire production data which analyzed using VIKOR methods and selected based on the optimum value to obtain the optimal combination of factors levels. The results of Taguchi's analysis are the first and third responses indicating the 16th experiment and second response indicating the 14th experiment which is the optimal combination. It can be concluded that Taguchi methods is inconsistent to producing optimal combination of levels of factors when dealing with multi-response problems, so additional methods are needed as Taguchi optimization methods in solving multi-response problems, including using VIKOR methods which results in the 2nd experiment being optimal combination.

Upaya pengelolaan daur ulang sampah kertas menjadi kertas baru telah banyak dilakukan pada jaman sekarang. Dibutuhkan suatu alat atau mesin yang mampu secara efektif dan efisien dalam mendaur ulang kertas bekas menjadi kertas baru. Terdapat beberapa faktor yang mempengaruhi tingkat efektifitas mesin daur ulang kertas diantaranya adalah ketebalan kertas. Salah satu metode yang dapat digunakan untuk menganalisis faktor-faktor yang mempengaruhi ketebalan kertas pada proses produksi kertas menggunakan mesin daur ulang kertas adalah analisis regresi. Analisis regresi merupakan teknik analisis data dalam statistika yang digunakan untuk mengkaji hubungan antara beberapa variabel bebas dengan variabel tidak bebas. Namun, jika ingin mengkaji hubungan atau pengaruh dua atau lebih variabel bebas terhadap satu variabel tidak bebas, maka model regresi yang digunakan adalah model regresi linier berganda. Tujuan dalam penelitian ini yaitu menganalisis faktor-faktor yang mempengaruhi ketebalan kertas pada mesin daur ulang kertas menggunakan regresi linier berganda serta memberikan informasi pemodelan mengenai hal tersebut. Hasil penelitian menunjukkan bahwa faktor yang mempengaruhi keoptimalan ketebalan kertas adalah penghancuran dan pemadatan kertas. Kata Kunci: analisis regresi linier berganda, langkah pembuatan kertas, ketebalan kertas, mesin daur ulang kertas
