Telecom: Lower Failure Rates and Maintenance Costs in Far Networks

As a global player, the AUNDE Group, with the AUNDE and ISRINGHAUSEN brands, offers the entire process chain from yarn to seat in the van, truck and bus divisions. A development team comprising more than 250 designers and engineers with 27 regional design and development sites in 14 countries has to respond to the market and development trends from around the globe, realizing customer wishes in a region-specific manner. The latest ISRI ® trend studies reveal innovations in the fields of functionality, comfort and sustainability.

Challenge

“The initial task was to take an examination of the behavior of one of the market areas in one of our regions, and get a better understanding of why they were seeing some issues. Was it tied to operational issues, or was it tied to the equipment? The root cause we came up with was that not every component had issues. The original analysis reflected that we had components that had aged but had life to them. Other devices were not as reliable. They had a higher failure rate.”

Solution

“We used ReliaSoft software because I had already used it, and I understood that it was mathematically accurate. So we were able to use ReliaSoft Weibull++, and take results out of Weibull++ and drop them into BlockSim. And what that gives us is an understanding of an individual component’s behavior, versus a systems and then a network behavior. When we came back with that analysis, the results were really something that opened the eyes of the executive leadership.”

Value

“Our executive leadership listened and made a multi-million dollar investment of capital to be able to replace parts. And to be able to come back and show what the improvement to the network is. It will be measured in reduction in trouble calls, truck rolls, and outages. We can take failure rates that are three, four, five or six percent, and get them down to one point two, one percent."
