|Title:||Grey trend relational model of production Cost for Torpedo|
|Keywords:||Production cost;Grey trend relational degree;Learning curve;Torpedo|
|Abstract:||For the same type of torpedo made in different batches, production cost will be different. In general, the cost is a downward trend with the increase of the batches. Production costs of different batches were divided into three data sequences with equal length, grey trend relational degree between the sequences is calculated. Equation based on trend consistent principle is established, and then the value of production cost can be predicted. A numerical example was provided to verify the properness of the model. Comparing with traditional methods, the result of the paper indicates that the grey trend relational model reflects the internal trend of production cost. It is suitable for predicting production cost of other productions that have a few bathes.|
