*Result*: Study of Achievement Stability Set for Parametric Linear FGP Problems.
*Further Information*
*Goal Programming has numerous advances, especially in the zone of brilliant modeling and it is a functional and powerful technique in the formulation, solution, and investigation of issues containing varied and conflicting objectives. The previous studies presented in this era focused on making the solution be stable. In addition, the achievement stability set introduced by Osman et al. [16] assumed a deterministic case even though real world problems possess uncertain natures which lead us to present the current study. In this research we introduce the achievement stability set for parametric linear fuzzy goal programming issues when the objective coefficients have a parametric nature. Firstly, the membership goals of each fuzzy goal were formulated then α -cut methodology is applied to obtain the deterministic feasible region. Secondly, the complete attainment problem is worked out and solved by utilizing the lexicographical approach. Finally, notions and strategies for finding the achievement stability set for parametric linear fuzzy goal programming issue and numerical examples are presented. [ABSTRACT FROM AUTHOR]*
