Deciding obsolescence strategies for vehicle fleets

Problem

• Modern vehicles (especially military ones) increasingly use complex electronic components that are often obsolete before the vehicle fleet leaves the production line
• The requirement for a sensible strategy on handling component obsolescence is therefore becoming a critical concern for fleet owners
• The wrong strategy could have catastrophic impacts on whole-life-cost or fleet reliability
• Agena's defence contractor client needed a method for determining obsolescence strategies for an arbitrary vehicle architecture

Solution

• The AgenaRisk solution involved automatically generating a class of risk maps directly from a description of the vehicle architecture
• The aggregated risk map provides an integrated analysis of cost-benefit options for sub-systems over multiple platforms affected by obsolete components

Benefits

• AgenaRisk predicts optimum number of spares and fleet levels for different usage and attrition profiles
• AgenaRisk minimises whole life costs and ranks the most cost-effective options
• AgenaRisk accounts for the effects of systems integration, COTS and supply chain fragility
• AgenaRisk identifies the causes of increased cost and poorer quality
