Abstract

In real-life decisions, usually we happen to suffer through different states of uncertainties. In order to counter these uncertainties, in this paper, the author formulated a transportation problem in which availability, demand and costs are mixed terms of real, triangular intuitionistic fuzzy numbers. In this paper, a simple method for solving type-3 intuitionistic fuzzy transportation is applied. So, the proposed method gives the optimal solution directly. The solution procedure is illustrated with the help of numerical examples.

Keywords: IFN, TIFN, IFTP of type - 3, Optimum Solution.

1. Introduction

The fuzzy set (FS) hypothesis was at first developed by [9] is useful from numerous points of view in various applications in different fields. The idea fuzzy numerical writing computer programs was created by Tanaka et al in 1947 outlining of fuzzy choice of [2]. Idea of Intuitionistic fuzzy sets (IFS's) recommended by [1] are chiefly valuable to manage numerous exemptions, disarray and ambiguities. The IFS's different the force of enrollment (MF) and the power of non-participation (NMF) of a component in the set. Uncertainties' assistance leader to concur the power of satisfaction, force of non-satisfaction and power of vulnerability for transfer and furthermore help to make determinant at stronghold degree of endorsement and non-endorsement for transportation cost (TC) in any transportation issue (TP). Also, without a doubt coming to dynamic issues IFS turned into an extreme technique which is for the most part closable. In like manner, its boss to use IFS diverged from FS to adapt to issues which our own dynamic or unworthiness. In

UNIQUE OPTIMAL SOLUTION FOR TIFTP OF TYPE-III_Volume 17, June 2022

[6], investigate a general report on TP in fuzzy climate. Along these lines, IFS's are utilized by numerous creators for various ideal issues. [3] presented math activities of IFS's. Various analysts are likewise chipped away at and with IFS's. PSK method for solving mixed and type-4 intuitionistic fuzzy transportation issue (IFTP) was introduced by [8] which limit, requests and cost are availability, demand and costs are mixed terms of real, triangular intuitionistic fuzzy numbers and an algorithmic methodology for tackling IFTP was introduced [4]. By utilizing [8] paper in this article we address mathematical model. [7] Presented another positioning capacity utilizing centroid of centroids of IFN's.

In this article, we will acquaint another transportation strategy with acquire an ideal arrangement in an IFTP. For the new transportation method mathematical model is tackled. Plinth of article is managed: Section 2 quintessence goal, Section 3 gives Ranking capacity, Section 4 arrangements goal of IFTP of type-3 and computational system, region 5 consists Numerical model, at long last conclusion given in region 6.

2. Preliminaries

In this part a couple of essential definitions and math tasks are examined.

~1FS

Intuiti°mstic Fuzzy Set (IFS): An IFS A in ^ an IFS is described as an object of following design

~1FS

A = {{x, ^~ifs (x), v~ifs (x)):x E X}

where the functions^/fs : X ^ [0, 1] and v~/fs: X ^ [0, 1] defines degree of Enrollment work and

non-participation elementx E X, respectively and 0 < №~ifs(x)>v~ifs(x) < 1, for every x EX.

~1FS

Intuitionistic Fuzzy Numbers (IFN's): A subset of IFS, A = { {x,^~ifs(x), v~ifs(x)) : x E X}, of real

Enrollment work and non-participation capacity of A is as follows,

xE(m.m + Pl] and =]0. x = rn,xE[rn + P2,*)

Where ft(x)and hi(x)\ i = 1,2 are strictly increasing and decreasing functions in [m — a^m) and

(m, m — Pi] respectively. at and are left and right spreads of ^~ifs(x)and v~ifs(x) respectively.

Arithmetic operations of TIFN:

~1fn ; ; ~1fn

For any two TIFN's A = (a1, a2, a3; a 1, a2, a 3)and5 = (b1, b2, b3; b 1, b2, b 3), arithmetic operations are as follows,

~1fn ~1fn ; ;

Addition:^ © B = (a1 + b1, a2 + b2,, a3 + b3; a 1 + b 1, a2 + b2, a 3 + b 3)

~1fn ~1fn ; ;

Subtraction: A — B = (a1 — b3, a2 — b2,, a3 — b1;a 1 — b 3,a2 - b2,a3 - b 1)

3. Ranking Function

Ranking function is taken from [7], i.e., the ranking function is defined [7], for Trapezoidal and triangular Intuitionistic fuzzy number as

b(aifn\ _ (ai + bi + 2(a2 + b3) + 5(a3 + b2) + (a4 + b^ /Awi + Sw^ R(A ■> = ( 18 18 ) R(AIFN^ = ^ + b1) + 14a2 + (a4 + + 5W2^

Consider w1 = w2 = 1, we get ranking function is

R(A,FN) = f(ai+ bi) + 14a2 + (a4 +

Comparison of TIFN's: To differentiate TIFN's and each other, we need to rank them. A capacity like R: F(R) ^R, which maps each TIFN's into real line, is called positioning capacity. Here, F(^)means the arrangement of all TIFN's.

~1fn

By using ranking function"r", TIFN's can be compared. Let A = (a1, a2,a3;a1, a2, a 3) and

~ifn it

B = (b1, b2, b3; b\, b2, b3)are two TIFN's thenR (¿/FW) = ai+14a2+2+a 1+a 3and R (bifn) = bl+14b2+b3+b 1+b 3then the orders are defined as follows

The TP is termed as type - III TIFTP having availability, demand and costs are mixed terms real, fuzzy and TIFN's. To find optimum solution TIFTP of type - III, we are using the following transportation strategy.

4.2. Proposed Transportation strategy (Used in [5])

Stage 1: In the given transportation problem calculate the differences between maximum and minimum cost for each row and column.

Stage 2: Find sum of row difference and column difference and denote row sum by R and column sum by C. Identify Maximum sum of row and column. Select maximum difference in row and column.

Stage 3: Choose cell having most minimal expense in row and column identified in stage 2. Stage 4: Make a feasible assignment to cell picked in stage 5. Delete fulfilled row/column. Stage 5: Repeat technique until all the designations has been made.

Stage 6: The Optimum solution and triangular intuitionistic optimum value is attained in step 5, is optimum solution [x^} and triangular intuitionistic fuzzy optimum value isXl=1 ^j=1 cij®xij.

6. Conclusion

In this article, a new method has evolved which provides the opportunity to find the optimal objective value of the TIFTP of Type 3in terms of mixed intuitionistic fuzzy numbers. Based on current examination, it very well may be presumed that it is much simple to apply proposed strategy when contrasted with existing techniques [7], for tracking down the ideal optimum solution of TIFTP of type - III. Consequently, it is smarter to utilize the proposed technique rather than existing strategies for tackling TIFTP of type - III.
