Study on some inventory models and supply chain inventory models in crisp and fuzzy environments

Abstract

Inventory problems and supply chain inventory problems are everyday real life problems. Here, we have formulated the some inventory problems and supply chain inventory problems based on some real assumptions and notations. The main objective of the thesis is to study on some inventory models and supply chain inventory models in crisp and fuzzy environments. Single item or multi item has been taken under limitation on storage space. Due to uncertainty all cost parameters are taken as the fuzzy number. To find out the optimal solution of our proposed models are used non-linear programming techniques in fuzzy and neutrosophic environments which are Fuzzy programming technique with hyperbolic membership function (FPTHMF), Fuzzy non-linear programming technique (FNLP), Fuzzy additive goal programming technique (FAGP), weighted Fuzzy non-linear programming technique (WFNLP) and weighted Fuzzy additive goal programming technique (WFAGP) and neutrosophic hesitant fuzzy non-linear programming technique (NHFNP). newline
