House of Reliability Costs: Developing Reliability Program Activities

Abstract

Reliability is an important factor in the management, planning, and design of an engineering product. In order to meet the customer's requirements and achieve desired reliability level, different types of activities should be performed by the system developer/manufacturer. These activities have to be listed in corresponding reliability program and include: inspection, spare parts storage/providing, failure analysis, etc. On one hand, each activity from reliability program list requires some cost for its realization. On the other hand, when any activity was not performed, we should expect some losses because of system's failures. This paper presents an innovative method that enables a company to determine its vital activities in reliability program. The method is based on a House of Reliability Costs for translating the system's failure costs into relative importance of corresponding activities listed in the reliability program. A Mean Square Error (MSE) criterion supports the selection of vital reliability program activities. It divides a set of activities in reliability program into two groups: vital few (activities in reliability program) and trivial many. The partition minimizes the overall MSE and so, delineates two homogeneous groups. A case study is presented to illustrate the application of the developed methodology in a warfare system. The vital reliability program activities -treatment routine and spare parts storage -were found to be the best activities for reducing the costs of the warfare failures.

“…By incorporating the super matrix of multi-level subsystem structure into the DEMATEL process, a hierarchical DEMATEL method with three algorithms is established to identify key factors. 14 In another study, Wang et al 15 proposed a stochastic dominance-based method for product concept development using a quality function deployment (QFD)-based model. The approach involves constructing a product planning house of quality (PPHoQ) as the core of the entire QFD model, followed by a processing method for studying system reliability known as the house of reliability (HoR).…”

Systematic Review of Methodologies for the Design for Reliability in the Product Development

“…For planning product reliability at early stages of development, it was brought up the necessity of using costumers' expectations as engineering requirements for developing new products. Dror (2013) and Reheja (2013) utilized QFD for planning and develop products that attend costumers needs.…”

“…Kurz, Lewitschnig and Pilz discuss a Bayesian estimation for Weibull early‐life failure distributions. Dror utilises a House of Reliability to develop reliability programme activities. McCollin and Coleman illustrate the importance of awareness, understanding and utilisation of physical knowledge when applying statistical methods in his work on statistical engineering by looking at a historical published maintenance data set in a reliability context.…”
