Abstract

In this paper, Reliability analysis is performed on screw press machines. The analysis starts with system reliability based on ten components and one-year failure data. To identify which component has a negative impact on system reliability and to what degree the impact is, reliabiity importance indices are performed based on Birnbaum and operational criticality index (OCI). By identifying the rank of component importances, maintenance could focus on the critical parts, and then improve system reliability. In addition, maintenance optimization for inspection and replacement schedule are also presented in this paper.

Abstract

 Penelitian ini bertujuan untuk melakukan identifikasi kegagalan pada chiller berdasarkan analisis parameter operasi kunci untuk masing-masing jenis kegagalan dengan menggunakan model regresi satu variabel. Hasil tersebut dibandingkan dengan penelitian yang dilakukan peneliti sebelumnya dengan model regresi tiga variabel. Hasil perbandingan berdasarkan kecenderungan perubahan parameter operasi menunjukkan bawah diagnosa kegagalan bisa dilakukan cukup tepat dengan menggunakan parameter operasi yang dihasilkan dari model regresi satu variabel
