Using DOE++ For Product and Process Optimization
In last month’s Reliability Basics article, we discussed reliability allocation. The purpose of reliability allocation is to meet the system reliability requirement and, in the meantime, to keep the cost as low as possible. High reliability usually means high cost. A desirable design is one that can provide satisfactory reliability with a minimal cost. This is an optimization problem with two responses: reliability and cost. In this article, we will illustrate how to use DOE++ to optimize several responses simultaneously.

A Pro-rata Warranty Model for Non-Repairable Products
In the current consumer market, a product’s warranty is one of the important factors in the consumer’s decision-making process. From vehicles to home appliances, when several products perform similar functions, customers usually prefer to purchase the product that provides the better warranty. In this article, we will discuss several warranty policies. One example will be given for calculating the predicted warranty cost.

* Certified Reliability Professional (CRP) Program - ReliaSoft's Certified Reliability Professional (CRP) program has been designed to distinguish professionals who have gained and successfully demonstrated unquestionable expertise in the field of reliability engineering. To achieve certification, candidates must complete a series of training courses focused on important reliability engineering topics, successfully apply the learned body of knowledge in the workplace and publicly present this expertise at an industry conference or in a journal. For more information about this certification program, please visit
* CRP Achievement Recognition - During the Applied Reliability Symposium (ARS) in Brazil we had the distinct pleasure of honoring thirteen recipients of the Certified Reliability Professional (CRP) Program certification for their outstanding achievement in reliability engineering:

* Getting on Top, Down Under - Consider joining us on July 27-31, 2009 in Perth, Australia for a 5-day seminar (RS540) designed to provide you with an overview of ways in which reliability engineering concepts and methods can be applied for repairable system analysis and maintenance planning. Topics include life data analysis, recurrent event data analysis, reliability block diagrams and reliability centered maintenance. Online registration is available at
* Arizona is HOT, but San Diego, California is Not - During these hot months, we like to move our training classes from our Tucson, Arizona headquarters over to San Diego, California. This year we are offering two foundational training seminars at the Catamaran Resort on Mission Bay:

MSMT Reliability Foundation Series provides a comprehensive treatment on the subject of life data analysis as it applies to reliability engineering as well as an introduction to accelerated life testing analysis and the use of reliability block diagrams (RBDs) for system reliability, maintainability and availability analysis. (August 24-28, 2009)

RS 560 Fundamentals of Design for Reliability provides an overview of the entire set of methods and tools that support Design for Reliability (DFR) initiatives from the initial concept through production. Topics include reliability goals, identifying critical items, quantifying and improving reliability and monitoring performance in the field. (September 2-4, 2009)
