        ## How to use
        
        Install
        
        `pip install ahp`
        
        
        use
        
        ```python
        from AHP import AHP
        import numpy as np
        
        # 准则重要性矩阵
        criteria = np.array([[1, 2, 7, 5, 5],
                             [1 / 2, 1, 4, 3, 3],
                             [1 / 7, 1 / 4, 1, 1 / 2, 1 / 3],
                             [1 / 5, 1 / 3, 2, 1, 1],
                             [1 / 5, 1 / 3, 3, 1, 1]])
        
        # 对每个准则，方案优劣排序
        b1 = np.array([[1, 1 / 3, 1 / 8], [3, 1, 1 / 3], [8, 3, 1]])
        b2 = np.array([[1, 2, 5], [1 / 2, 1, 2], [1 / 5, 1 / 2, 1]])
        b3 = np.array([[1, 1, 3], [1, 1, 3], [1 / 3, 1 / 3, 1]])
        b4 = np.array([[1, 3, 4], [1 / 3, 1, 1], [1 / 4, 1, 1]])
        b5 = np.array([[1, 4, 1 / 2], [1 / 4, 1, 1 / 4], [2, 4, 1]])
        
        b = [b1, b2, b3, b4, b5]
        a = AHP(criteria, b).run()
