The `WASPAS`

function implements the Weighted Aggregated Sum Product ASsessment (WASPAS) Method.

1 |

`decision` |
The decision matrix ( |

`weights` |
A vector of length |

`cb` |
A vector of length |

`lambda` |
A value in [0,1]. It is used in the calculation of the W index. |

`WASPAS`

returns a data frame which contains the score of the WSM, WPM and the Q index and the ranking of the alternatives.
