Using Off-Site Spare Part Stocks to Maintain Systems
Companies that rely on assets to run their business often need to maintain stocks of spare parts. Where to set up these stocks, how many parts to keep in them and how often to restock them is a logistics question that affects the ability of the company to fix failures and maintain their systems. It is difficult to strike a balance between carrying enough parts to meet the company's needs and containing the costs involved in sustaining such stocks. A blend of on-site and off-site spare part stocks can be a cost-effective strategy. This article explains how to set up and use a combination of on-site and off-site spare part stock profiles when analyzing your systems using BlockSim 7.

Reliability Basics

Expanded Models for Accelerated Life Test Analysis with Time-Varying Stresses
Some accelerated life tests may use a time-varying stress application (such as step-stress or ramp-stress) to assure the observation of failures more quickly in order to shorten the product development cycle. Likewise, some products are expected to be operated under normal use conditions where the stress exposure varies with time. When performing data analysis for these types of situations, the life-stress relationship model must take into account the cumulative effect of the applied stresses. Such a model is commonly referred to as a cumulative damage or "cumulative exposure" model. ReliaSoft's ALTA PRO software supports the use of the cumulative damage model for data with time-varying stresses and with the recent release of Version 7, the software is now capable of analyzing data with multiple time-varying stresses. This article presents a summary of the four versions of the cumulative damage model available in ALTA 7 PRO, along with information about how these models may be applied.

* Certified Reliability Professional (CRP) program - This 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 in an industry conference or journal. The CRP program was initiated and is managed by ReliaSoft Corporation. For more information, please visit http://www.ReliabilityProfessional.org/ or contact the office that serves your region.
* North American ARS 2007 Coming Up Fast! The International Applied Reliability Symposium will once again provide a forum for industry experts and reliability practitioners to discuss the practical application of reliability principles. Real world challenges and the success stories associated with them will be the primary focus. Dont miss this rapidly approaching event. Simply visit http://www.ARSymposium.org/register.htm to register now. The Symposium is scheduled for June 20 - 22, 2007 at the Catamaran Resort on Mission Bay in San Diego, California. Rooms must be reserved by May 18, 2007 to be eligible for the reduced rate.
* Congratulations Seagate! In 2006, Seagate Technology partnered with ReliaSoft Corporation to develop a customized in-depth Design For Reliability training curriculum.  The joint development project relied upon ReliaSoft's extensive expertise in providing training for key reliability engineering topics combined with Seagate's own engineering experience and detailed knowledge about specific practical applications within the organization. The intensive collaboration effort was completed on schedule and the training modules have been rolled out globally to hundreds of Seagate engineers as part of an overall corporate Business Excellence strategy. The training curriculum has been very well received within Seagate, recently winning the award for "Best Training Program or Strategy" at the 2007 Business Excellence Seminar in San Francisco.
* FMEA Accelerator - ReliaSoft's FMEA Accelerator is your key to accessing an outstanding collection of FMEA templates for a wide variety of components. Each FMEA template is a generic failure mode analysis for a particular type of component/equipment, which can be used as a starting point for a companys own specific analysis. The FMEA Accelerator utility makes it easy to search for and import selected data into your own analyses performed in ReliaSoft's Xfmea Standard, Xfmea Enterprise or RCM++ software (version 4.0.2 or higher). FMEA templates are sold individually or by collection. The MRG Physical Asset FMEA Template Collection, offering over 230 templates for components ranging from Blowers, Boilers and Conveyors to Pumps, Tanks, Valves and much more, is currently available and additional collections are planned for the future. Visit http://www.ReliaSoft.com/fmea/ for more information.
