This paper deals with the problem of clustering of asymmetric data. A method of the problem solving is based on the application of a direct possibilistic clustering algorithm based on the concept of allotment among fuzzy cluster to a matrix of fuzzy tolerance. which correspond to the set of objects. for which asymmetric distances or proximities hold. https://www.roneverhart.com/Arjo-Sara-Stedy-Stand-Assist-Manual-Patient-Standing-Aid/
