This paper deals with the issue of safety lead time (SLT) calculations in production-inventory systems in presence of both demand and replenishment lead time variability. We provide some formulations of the SLT and numerically show their performance as compared to a benchmark in the literature. Thus the main objective of this paper is to provide analytical formulations to calculate th... https://safeersappliancers.shop/product-category/aeg-bpk842720m-electric-single-stainless-steel-pyrolytic-oven/
