In this study, we present a technique to solve
LR
-type fully bipolar fuzzy linear programming problems (FBFLPPs) with equality constraints. We define
LR
-type bipolar fuzzy numbers and their arithmetic operations. We discuss multiplication of
LR
-type bipolar fuzzy numbers. Furthermore, we develop a method to solve
LR
-type FBFLPPs with equality constraints involving
LR
-type bipolar fuzzy numbers as parameters and variables. Moreover, we define ranking for
LR
-type bipolar fuzzy numbers which transform the
LR
-type FBFLPP into a crisp linear programming problem. Finally, we consider numerical examples to illustrate the proposed method.
