Welding flux design involves optimising multiple quality attributes which are often conflicting and are of varying degree of concern to the stakeholders. The attributes are often selected as design criteria and are sometimes at different levels in the hierarchy such as primary, secondary and tertiary attributes. The articulation and incorporation of the opinions of stakeholders concerning the intensity of importance attached to each attribute at all the levels in the hierarchy in the optimisation process has remained a challenge. In this study, a framework was proposed for the articulation and incorporation of the preferences of stakeholders concerning all levels of attributes and illustrated with a lifecycle welding flux design case from the literature involving 5, 21 and 25 primary, secondary and tertiary criteria, respectively. Fifteen out of the 21 secondary criteria could not be further unbundled and were added to the tertiary criteria to make 40 lowest level criteria. The subjective judgements of stakeholders were converted to weighting coefficients using the analytical hierarchy process. The coefficients for the lowest level criteria were converted to global weights which were the preference indices for use in the optimisation models. Based on the values of , moisture pick-up, extrudability and slag detachability were ranked 1st , 2nd , and 3rd respectively and the respective 38th, 39th and 40th lowest level criteria were fume generation, dilution and charpy impart strength.

Abstract The arrival of new industries in some municipalities of ‘El Bajío’ in Guanajuato state, Mexico, has brought about appreciable economic development and human impacts, but has also caused changes in the management of the aquifers from which they get water for their operations. In some cases, the aquifers are overexploited and contaminated at different levels. A number of agencies have the main responsibility for managing, protecting and conducting studies on water use in both municipalities and the state and, in this context, experts from these agencies were consulted as part of this study about what environmental, social, economic and hydrological aspects had the highest priority when considering the establishment of a new industry in the zone. The analytical hierarchy process (AHP) methodology was used. Results show that hydrological aspects were the most important and, within them, treatment and reuse of water had the highest priority. It was concluded, therefore, that for the experts to reuse water in some activities and productive processes must be an option to decrease the water extraction from aquifers, supposing that the treatment process complied with the required regulations. Given the present conditions in the region, we can affirm that these results are applicable to the whole of El Bajío.

Beasiswa Peningkatan Prestasi Akademik (PPA) sebagai salah satu bentuk dukungan pemerintah Republik Indonesia terhadap dunia pendidikan. Beasiswa yang disalurkan oleh pemerintah melalui Perguruan Tinggi yang ada di Indonesia ini, penyeleksian dan penetapan penerimanya sepenuhnya diserahkan kepada pihak Perguruan Tinggi yang bersangkutan. Tahap inilah yang sangat rentan terjadinya kecurangan. Pada objek penelitian  yang diteliti hingga saat ini proses penyeleksian masih dilakukan dengan menggunakan Microsoft Excel, hal ini tentu saja kurang efektif dan efisien, serta rentan akan terjadinya kesalahan bahkan kecurangan. Untuk itu, diperlukan suatu metodologi dan aplikasi yang tepat dalam melakukan penyeleksian penerima beasiswa tersebut. Decision Support System digunakan sebagai solusi untuk melakukan perekomendasian penerima beasiswa, khususnya dengan menggunakan Metode Technique  for  Order  Preference  by  Similarity  to  Ideal  Solution  (TOPSIS)  dan  Analytical  Hierarcy Process (AHP). Penggunaan kombinasi dua metode tersebut dilakukan agar memiliki tingkat akurasi yang baik jika dibandingkan  dengan menggunakan satu metode. Hasilnya,  aplikasi  decision support system dengan penerapan kombinasi metode Topsis dan AHP berhasil di rancang dan di ujicoba, serta sukses dalam perekomendasian penerima beasiswa PPA dengan menghasilkan data alternatif mahasiswa yang terurut mulai dari nilai preferensi yang paling tinggi 0.764 hingga terendah 0.189. Hasil ini dapat menjadi rekomendasi bagi pengambil keputusan dalam mengambil keputusan yang efektik, efisien dan dapat dipertanggung jawabkan.
