A fuzzy multi item displayed inventory model with generator cost using trapezoidal and pentagonal fuzzy

Abstract

The management of the inventory system becomes more and more important for newlinethe enterprises in the real-life situations. Inventory consists of usable but idle resources. newlineWhen the resource involved is material or goods, it is referred as stock or simply as newline Inventoryand#8223;. In a broad sense, inventory may be defined as the stock of goods, newlinecommodities or other economic resources that are stored or reserved in order to ensure newlinesmooth and efficient running of business affairs. newlineThe main objective of this thesis is to construct different types of display newlineinventory models in both crisp and fuzzy environment and determine the decision newlinevariables so as to maximize the average profit and minimize the average total cost. newlineThe first chapter covers preliminary definitions and the literature survey newlinepertaining to the crisp and fuzzy inventory models. The author has carried out the cost newlineanalysis for the following display inventory models by comparing the crisp and fuzzy newlineenvironment. newlineand#61656; A Fuzzy Multi-Item Displayed Inventory Models with Generator Cost using newlineTrapezoidal and Pentagonal Fuzzy Number under Space Constraint and Quality newlineConstraint. newlineand#61656; Multi-Objective and Multi-Item Displayed Inventory Model using Nearest newlineInterval Approximation of Pentagonal Fuzzy Number. newlineand#61656; A Multi-Item Displayed Inventory Models with Pentagonal Fuzzy Number using newlinetwo Defuzzification Techniques newlineand#61656; A Probabilistic Multi - Objective, and Multi - Item Inventory Models with newlineRanking of Circumcenter of Centroid of Pentagonal Fuzzy Number. newlineand#61656; A Stochastic Vector Objective Inventory Model using Pentagonal Fuzzy Number newlinewith and without Partial Backordering under some Constraints newlineand#61656; A Vector Objective, Multi - Showroom and Multi -Item Displayed Inventory newlineModels with Pentagonal Fuzzy Number using two Defuzzification Techniques. newline newline
