An analysis of the optimal multiobjective inventory clustering decision with small quantity and great variety inventory by applying a DPSO.

Wang ST, Li MH - ScientificWorldJournal (2014)

Bottom Line: Without the requirement of prior inventory knowledge, inventory items are automatically clustered into near optimal clustering number.The obtained clustering results should satisfy the inventory objective equation, which consists of different objectives such as total cost, backorder rate, demand relevance, and inventory turnover rate.This study integrates the above four objectives into a multiobjective equation, and inputs the actual inventory items of the enterprise into DPSO.

ABSTRACT
When an enterprise has thousands of varieties in its inventory, the use of a single management method could not be a feasible approach. A better way to manage this problem would be to categorise inventory items into several clusters according to inventory decisions and to use different management methods for managing different clusters. The present study applies DPSO (dynamic particle swarm optimisation) to a problem of clustering of inventory items. Without the requirement of prior inventory knowledge, inventory items are automatically clustered into near optimal clustering number. The obtained clustering results should satisfy the inventory objective equation, which consists of different objectives such as total cost, backorder rate, demand relevance, and inventory turnover rate. This study integrates the above four objectives into a multiobjective equation, and inputs the actual inventory items of the enterprise into DPSO. In comparison with other clustering methods, the proposed method can consider different objectives and obtain an overall better solution to obtain better convergence results and inventory decisions.

fig5: Comparison of number of competition items of tournament selection.

Mentions: For the comparison of competing items in tournament selection, each experiment is performed 30 times. Figure 5 shows the comparison of the competition items of tournament selection in the case of candidates 2 to 6. As seen, better convergence effect can be achieved when the number of race candidates (n) is 3.
