Production flow analysis

In operations management and industrial engineering, production flow analysis refers to methods which share the following characteristics:
Methods differ on how they group together machines with products. These play an important role in designing manufacturing cells.
Rank Order Clustering.
Given a binary product-machines n-by-m matrix formula_1, Rank Order Clustering is an algorithm characterized by the following steps:
Similarity coefficients.
Given a binary product-machines n-by-m matrix, the algorithm proceeds by the following steps:
Unless this procedure is stopped the algorithm eventually will put all machines in one single group.
