Abstract

For high technology working environment Reliability Analysis is done according to many different methodologies such as MIL-HDBK-217F and Telcordia SR-332 in design phase or Weibull Distribution with field data in usage phase. The objective of this paper is to compare MTBF calculation methods in order to get a methodology for more accurate MTBF values. In this article; Mean Time Between Failure (MTBF) values calculated based on MIL-HDBK-217F standard and Weibull Distribution are compared for the systems used Defense Industry. On the conclusion of the article; the results are examined and as a result, it is recommended that It can be find out a correction coefficient that would make MIL-HDBK-217F standard better for more reliable MTBF values.

Savunma Sektöründeki Sistemlerin Arızalar Arası Ortalama Süre Analizi

Abstract

Yüksek teknolojili çalışma ortamları için Güvenilirlik Analizi, tasarım aşamasında MIL-HDBK-217F ve Telcordia SR-332 veya kullanım aşamasında saha verileriyle Weibull Dağıtımı gibi birçok farklı metodolojiye göre yapılmaktadır. Bu makalenin amacı, daha doğru Arızalar Arası Ortalama Süre (AAOS) değerleri için bir metodoloji elde etmek amacıyla AAOS hesaplama yöntemlerini karşılaştırmaktır. Bu makalede; Savunma Sanayiinde kullanılan sistemler için MIL-HDBK-217F standardı ve Weibull Dağılımı baz alınarak hesaplanan AAOS değerleri karşılaştırılmıştır. Yazının sonuç kısmında; sonuçlar incelenmiş olup daha güvenilir AAOS değerleri için MIL-HDBK-217F standardını daha iyi hale getirecek bir düzeltme katsayısının bulunabileceği önerilmektedir.
