解説
問 7
Incorrectア
The denominator adds function in addition to cost, but in VE value is purely the ratio of function to cost, and there is no basis for adding cost and function together in the denominator. Its form differs from the standard V = F / C, so it is wrong.
- イ
正解 In Value Engineering (VE), value is defined as Function ÷ Cost, that is, V = F / C. Function represents the role and performance that a product or service fulfills, while cost represents the expense needed to achieve it. With the same cost, higher function raises the value; with the same function, lower cost raises the value. The value improvement that VE aims for is achieved exactly as this formula shows, by raising the function in the numerator or lowering the cost in the denominator. Therefore choice イ, which expresses Value = Function / Cost, is correct.
Incorrectウ
Because function and cost are multiplied, the larger the cost, the higher the value becomes. This contradicts the VE idea of raising value by reducing cost, so it is wrong.
Incorrectエ
The numerator and denominator of function and cost are reversed. This would mean that the higher the cost and the lower the function, the higher the value, which is the exact opposite of the VE definition, so it is wrong.
ここがポイント
- The basic formula of Value Engineering (VE) is Value = Function / Cost (V = F / C).
- To raise value, either improve the function in the numerator or lower the cost in the denominator.
