PROBLEM TO BE SOLVED: To provide a cost estimation device capable of estimating product cost in as short a time as possible.SOLUTION: When a product is evaluated so that distribution of estimation actual follows predetermined probability distribution, a second evaluation value for evaluating a first evaluation value which is a probability variable corresponding to a maximum of probability frequency in the probability distribution and variation of the probability distribution are calculated. When a product is evaluated so that distribution of the estimation actual does not follow the predetermined probability distribution, a third evaluation value corresponding to a central value of the distribution of the estimation actual, a fourth evaluation value which is difference between the central value and maximum of the estimation actual, and a fifth evaluation value which is a difference between the central value and the minimum of the estimation actual, are calculated by a component cost estimation part 161b. A product cost estimation part 161c aggregates the first and third evaluation values, and aggregates the second, fourth and fifth evaluation values calculated by the component cost estimation part 161b. |
