Abstract

This paper presents an integrated inventory model that examines imperfect production processes in the context of intuitionistic fuzzy demand. Defective products identified during the inspection process undergo rework before being released for sale. The dynamic production system allows for adaptability to the environment, with the production cost tied to the variability in production rates. Acknowledging the substantial carbon dioxide emissions from industries and transportation, the manufacturer aligns item production with carbon emission levels and incurs a corresponding carbon emission tax. Market demand for the item is represented as a triangular intuitionistic fuzzy number due to inherent uncertainty. The primary objective of this study is to minimize the integrated cost function of the proposed model through multivariable calculus. Numerical experiments are conducted to assess the model's performance, and sensitivity analysis is employed to validate the effectiveness of the optimal parameters.
