Meaning
Reliability engineering uses a multi-variable mathematical equation to calculate the joint effect of temperature, humidity, and electrical stress on the rate of material degradation. Supply contracts use the eyring stress model to forecast the operating life of electronic retail displays and lights under heavy use. This model does not apply when the product is subjected to physical impact or chemical corrosion.
Accelerated Degradation
Performance projections based on the eyring stress model allow manufacturers to estimate the lifetime of their products before they are deployed in high-stress retail environments. This calculation guides the selection of materials and components. This prevents premature product failures.
Service Commitment
Warranty liabilities are negotiated using these stress models to determine the duration and scope of the supplier’s service commitments. If the eyring stress model predicts a high risk of failure under typical store conditions, the supplier must either improve the product’s design or offer a shorter warranty period to the distributor. This choice directly affects the pricing and attractiveness of the product to the retail buyer.
If the product fails at a rate higher than predicted, the supplier must cover the replacement and labor costs.
Contractual Limit
Accurate stress modeling reduces the financial risk for both parties. It ensures that the warranty terms match the product’s actual capabilities.
