This paper presents taxonomy of detailed literature reviews on bi-level programming
problems (BLPPs), multi-level programming problems (MLPPs) and associated research …

Optimization makes processes, systems, or products more efficient, reliable, and with better
outcomes. A popular topic on optimization today is multiobjective bilevel optimization …

This paper discusses a new algorithm for generating the Pareto frontier for bi-level multi-
objective rough nonlinear programming problem (BL-MRNPP). In this algorithm, the …

This paper lists in alphabetical order by the name of the first author, 532 papers dealing with
fractional programming and its applications. This covers mainly the period 2012–2015 but it …

Several methods currently exist for solving fuzzy linear fractional programming problems
under non negative fuzzy variables. However, due to the limitation of these methods, they …

This paper is designed based on the mathematical models for bi-level programming in
Stackelberg game under type-2 fuzzy environment. The parameters of the objective …

Despite the important role of bi-level multi-objective linear fractional programming (BL-
MOLFP) problem for many hierarchical organizations, a very little success has been …

Fuzzy rough bi-level multi-objective nonlinear programming problem (FRBMNPP) moved
toward becoming rise normally in various real applications. In this article we develop bi-level …

Purpose: We formulate a linear fractional programming (LFP) problem in which costs of the
objective functions and constraints all are taken to be trianaular fuzzy numbers …

Many developments of fuzzy sets have been suggested to accomplish uncertain information
in real-world problems. But, in the greatest cases, fuzzy sets in two-dimensions or type-1 …
