G R Williams: 1244. Weight Risk Analysis. 1978.



Weight Risk Analysis can be defined as the determination of the degree of risk involved in achieving a given weight for a vehicle. This paper presents an approach to Weight Risk Analysis that is practical to apply, using a mathematically correct procedure to determine total vehicle risks from engineering judgments made on a more elemental level.
Weight Risk Analysis can be important in several aspects of management decision making: For example
1) Understanding of weight risks can be instrumental in management decisions regarding chances for a successfully performing product
– What weight can we guarantee?
– How do weight risks influence performance we can guarantee?
– Are weight risks such that we are likely to have an unsellable product after it is built and in service?
2) Understanding of weight risks can influence management decisions regarding where and when to spend money on product development
– How much should be spent on weight reduction?
– How much should be spent to reduce risks?’
– Which risks are most important to reduce?
In short, understanding of weight risks provides management with additional insight to help make product decisions.
Weight risk assessment is not new – it has always been done, although usually subjectively. Weight Growth Studies and efforts to project weight at delivery from the vehicle weight at some stage in design is a specialized form of weight risk assessment. These studies have been particularly useful in establishing target weights.
