PSK Method for Solving Type-1 and
Type-3 Fuzzy Transportation Problems
P. Senthil Kumar, PG & Research Department of Mathematics, Jamal Mohamed College (Autonomous), Tiruchirappalli,
Tamil Nadu, India
ABSTRACT
In conventional transportation problem (TP), supplies, demands and costs are always certain. In this
paper, the author tried to categories the TP under the mixture of certain and uncertain environment
and formulates the problem and utilizes the crisp numbers, triangular fuzzy numbers (TFNs) and
trapezoidal fuzzy numbers (TrFNs) to solve the TP. The existing ranking procedure of Liou and Wang
is used to transform the type-1 and type-3 fuzzy transportation problem (FTP) into a crisp one so that
the conventional method may be applied to solve the TP. The solution procedure differs from TP to
type-1 and type-3 FTP in allocation step only. Therefore, the new method called PSK method and
new multiplication operation on TrFN is proposed to find the mixed optimal solution in terms of crisp
numbers, TFNs and TrFNs. The main advantage of this method is computationally very simple, easy
to understand and also the optimum objective value obtained by our method is physically meaningful.
The effectiveness of the proposed method is illustrated by means of a numerical example.

Fuzzy Transportation Problem
1. INTRODUCTION
The transportation problem is a special class of linear programming problem which deals
with the distribution of single homogeneous product from various origins(sources) to various
destinations(sinks).The objective of the transportation problem is to determine the optimal amount
of a commodity to be transported from various supply points to various demand points so that the
total transportation cost is minimum for a minimization problem or total transportation profit is
maximum for a maximization problem.
The unit costs, that is, the cost of transporting one unit from a particular supply point to a particular
demand point, the amounts available at the supply points and the amounts required at the demand
points are the parameters of the transportation problem. Efficient algorithms have been developed
for solving transportation problems when the cost coefficients, the demand and supply quantities
are known precisely.
In the history of mathematics, Hitchcock (1941) originally developed the basic transportation
problem. Charnes and Cooper (1954) developed the stepping stone method which provides an
alternative way of determining the simplex method information. Appa (1973) discussed several
variations of the transportation problem. Arsham et al. (1989) proposed a simplex type algorithm

for general transportation problems. An Introduction to Operations Research Taha (2008) deals the
transportation problem.
In today’s real world problems such as in corporate or in industry many of the distribution
problems are imprecise in nature due to variations in the parameters. To deal quantitatively with
imprecise information in making decision, Zadeh (1965) introduced the fuzzy set theory and has
applied it successfully in various fields. The use of fuzzy set theory becomes very rapid in the field of
optimization after the pioneering work done by Bellman and Zadeh (1970). The fuzzy set deals with
the degree of membership (belongingness) of an element in the set. In a fuzzy set the membership
value (level of acceptance or level of satisfaction) lies between 0 and 1 where as in crisp set the
element belongs to the set represent 1 and the element not belongs to the set represent 0.
Due to the applications of fuzzy set theory, several authors like Oheigeartaigh (1982) presented
an algorithm for solving transportation problems where the availabilities and requirements are fuzzy
sets with linear or triangular membership functions. Chanas et al. (1984) presented a fuzzy linear
programming model for solving transportation problems with fuzzy supply, fuzzy demand and crisp
costs. Chanas et al. (1993) formulated the fuzzy transportation problems in three different situations and
proposed method for solving the formulated fuzzy transportation problems. Chanas and Kuchta (1996)
proposed the concept of the optimal solution for the transportation problem with fuzzy coefficients
expressed as fuzzy numbers, and developed an algorithm for obtaining the optimal solution.
Chanas and Kuchta (1998) developed a new method for solving fuzzy integer transportation
problem by representing the supply and demand parameters as L-R type fuzzy numbers. Saad and
Abbas (2003) proposed an algorithm for solving the transportation problems under fuzzy environment.
Liu and Kao (2004) presented a method for solving fuzzy transportation problems based on extension
principle. Chiang (2005) proposed a method to find the optimal solution of transportation problems
with fuzzy requirements and fuzzy availabilities. Gani and Razak (2006) obtained a fuzzy solution
for a two stage cost minimizing fuzzy transportation problem in which availabilities and requirements
are trapezoidal fuzzy numbers using a parametric approach. Das and Baruah (2007) discussed Vogel’s
approximation method to find the fuzzy initial basic feasible solution of fuzzy transportation problem
in which all the parameters (supply, demand and cost) are represented by triangular fuzzy numbers.
Li et al. (2008) proposed a new method based on goal programming approach for solving fuzzy
transportation problems with fuzzy costs.
Chen et al. (2008) proposed the methods for solving transportation problems on a fuzzy network.
Lin (2009) used genetic algorithm for solving transportation problems with fuzzy coefficients.
Dinagar and Palanivel (2009) investigated the transportation problem in fuzzy environment using
trapezoidal fuzzy numbers. De and Yadav (2010) modified the existing method (Kikuchi 2000) by
using trapezoidal fuzzy numbers instead of triangular fuzzy numbers. Pandian et al. (2010) proposed
a new algorithm for finding a fuzzy optimal solution for fuzzy transportation problem where all the
parameters are trapezoidal fuzzy numbers. Mohideen and Kumar (2010) did a comparative study on
transportation problem in fuzzy environment. Sudhakar et al. (2011) proposed a different approach for
solving two stage fuzzy transportation problems in which supplies and demands are trapezoidal fuzzy
numbers. Hadi Basirzadeh (2011) discussed an approach for solving fuzzy transportation problem
where all the parameters are trapezoidal fuzzy numbers. Gani et al. (2011) presented simplex type
algorithm for solving fuzzy transportation problem where all the parameters are triangular fuzzy
numbers. Nasseri and Ebrahimnejad (2011) did sensitivity analysis on linear programming problems
with trapezoidal fuzzy variables.
Biswas and Modak (2012) studied using fuzzy goal programming technique to solve multi-
objective chance constrained programming problems in a fuzzy environment. Saati et al. (2012)
presented a two-fold linear programming model with fuzzy data. Ebrahimnejad (2012) discussed
cost efficiency measures with trapezoidal fuzzy numbers in data envelopment analysis based on
ranking functions: application in insurance organization and hospital. Rani et al. (2014) presented a
method for unbalanced transportation problems in fuzzy environment taking all the parameters are
