ABSTRACT
In this paper, we use Octagonal fuzzy numbers (OFN) to define a structurally constrained single-server queuing model with the imposition of reneging customers through DSW algorithm. The primary objective of this study is to examine how well a single-server queueing model with a finite capacity performs under the assumptions of octagonal fuzzy queuing theory. The entry and departure rates are described as fuzzy with fuzzy number computation implemented. The evaluation metrics for fuzzy queuing theory are given as a range and wide range of values. The process metrics are evaluated using a defined methodology in which the fuzzy values are used directly without being transformed into crisp values. To verify the attainability of the miniature, the mathematical predecessor is enclosed around each sort of fuzzy number.
