This form of utility function was first conceptualized by Wassily Leontief. == Examples == Leontief utility functions represent complementary goods. For example: * Suppose $x\_1$ is the number of left shoes and $x\_2$ the number of right shoes. A consumer can only use pairs of shoes. Hence, his utility is $\backslash min(x\_1,x\_2)$. * In a cloud computing environment, there is a large server that runs many different tasks. Suppose a certain type of a task requires 2 CPUs, 3 gigabytes of memory and 4 gigabytes of disk-space to complete. The utility of the user is equal to the number of completed tasks. Hence, it can be represented by: $\backslash min(,\; ,\; )$. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Leontief utilities」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
