Ritha Department of Mathematics, Holy Cross College (Autonomous), Affiliated to Bharathidasan University, Tiruchirappalli – 620002, Tamilnadu, India Infallibility is an important factor both in fabrication repertoire replica and in the great demand of products. During a fabrication process, more exemplary products with high reliableness aim for increase in product demand although credit rating too is a prominent business strategy. Integrating the above duo concepts, we explain and explore mathematically a fabricating repertoire replica with partisan layaway stratagem and infallibility effect on the fabrication system wherein the demand of the customers is reliant on the product cost and rate of decay is regarded as constant. In this propounded model, commerce layaway stratagem on the fabricator and the customer is acquainted by considering all the achievable sitch due to permitted credit (layaway) duration. As a consequence, considering all the achievable instances for the fabricator and the customer’s layaway duration, seven non-linear optimization issues for the proposed replica are required. 2024 196 207 2659 https://creativecommons.org/licenses/by/4.0/ 10.54216/IJNS.240118 https://www.americaspg.com/journal/21/article/2659 https://www.americaspg.com/storage/41712964597.pdf
