Abstract

Geometric programming (GP) optimization techniques are an important and interesting topic since the 1970s. The significant development can be realized by having enormous researches in this field, such as fuzzy geometric optimization technique, multiobjective goal geometric programming, different goal geometric programming techniques, etc. Thus this chapter investigates a new algorithm based on the spherical fuzzy set (SFS) named as spherical fuzzy geometric programming problem (SFGPP) under the spherical fuzzy environment. The SFGPP inevitably involves the degree of neutrality along with truth and a falsity membership degree of the element into the feasible decision set. It also generalizes the decision set by imposing the restriction that the sum of squares of each membership function must be less than or equal to one. The attainment of achievement function is determined by maximizing the truth and minimizing the neutral and negative membership degree of each objective function under the spherical fuzzy decision set. At last, numerical examples and conclusions are presented to reveal the applicability and future research scope in the SF domain.
