Joint replenishment of associated spare parts using clustering approach.

- Abstract
Most often, we observe that certain spare parts are used together for various maintenance activities of equipment. If spare parts are used frequently in a group, then there exists some hidden dependency among these parts. Sometimes the entire maintenance work cannot be accomplished due to the shortage of a single spare in the group. These parts are termed here as associated spare items. These parts can be determined by frequent itemsets mining. In this paper, the groups of spare parts are found out through hierarchical clustering method using support and weighted support of the data mining measure. A methodology is proposed to incorporate both support and weighted support values for computing an overall cost of replenishment for joint replenishment policy for the associated spares. Finally, a case study is presented to illustrate the validation of our model and compared the results among the group with normal support and group with weighted support.
