One of these is linear programming problems. Upto best of our knowledge, in literature, sensitivity analysis for FVLP (Fuzzy Variable Linear Programming) problem has never been treated using ranking function. In this paper the sensitivity analysis for FVLP problems is studied using ranking function. Purpose is to introduce a simpler and convenient way to tackle the sensitivity analysis for FVLP problems. At the end it is shown that if in a FVLP problem both 'cost' and 'decision variables' are fuzzy numbers, then accuracy upto only rank can be obtained.","PeriodicalId":308518,"journal":{"name":"Journal of Fuzzy Set Valued Analysis","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130959522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then the solution will be compared in two cases. The first case is the one where displacement is not performed. It means that right side of nth-order fuzzy differential equation not transfer to the left side. The second case is the one where displacements is performed by applying generalized Hukuhara difference concept. We show that forcing term under gH-difference dose not exist when a displacement is not performed and the solution of bout fuzzy differential equations is the same considering gH- difference.

In this paper, we want to investigate them and propose mathematical models to find an answer for these questions. Since Most of the parameters in this process are linguistics and fuzzy logic is a powerful tools to handle them, a fuzzy linear programming model is used in model building. To this end, Fuzzy Linear Programming Problem(FLP) with fuzzy related system of constraint and fuzzy coefficient vector in the objective function, that is a full fuzzy system of simultaneous equations with fuzzy objective function is discussed. The related production operations in the objective function and in the constrains are performed in the basis of standard production between fuzzy numbers.
