Ravishankar ABSTRACT. In today’s daily life situations TP we frequently face the situation of unreliability in addition to unwillingness due to various unmanageable compo- nents. To handle with unreliability and unwillingness multiple researchers have recommended the intuitionistic fuzzy (IF)delineation for material. So, here, we contemplate a fuzzy TP of type - 1 IFN’s, i.e., availability and demand are TIFN’s and costs are real numbers. We apply IFZPM and IFMODIM to find optimum solution of a IFTP of type-1 make use of proposed ranking function. The same existing method is applied to proposed ranking function is comparatively give the same result. A relevant numerical example is also included. 1. I NTRODUCTION The fuzzy set (FS) theory was initially invented by Zadeh [8] is helpful in many ways in different applications in various fields. The concept fuzzy math- ematical programming was invented by Tanaka et al in 1947 framing of fuzzy decision of Bellman et al [2]. Concept of Intuitionistic fuzzy sets (IFS’s) sug- gested by Atanassov [1] are mainly useful to deal with many exceptions, con- fusion and ambiguities. The IFS’s separate the intensity of membership (MF) 1 corresponding author 2020 Mathematics Subject Classification. 03E72. Key words and phrases. IFN, TIFN, IFTP of type - 1, Optimum Solution.
