    New Approach for Solving Fully Interval-Value Fuzzy Transportation Problems
    (Springer Science and Business Media Deutschland GmbH, 2023) Ebrahimnejad, A.; Lotfi, F.H.; Allahviranloo, T.
    The transportation problem (TP) is one of the most broadly studied fields in the literature of linear programming problems used to a wide variety of practical applications. Conventional TPs generally assume that the values of transportation costs and the values of demand and supply are defined by real variables, though these values are unpredictable in TPs due to some uncontrollable factors. The present study formulates a TP when all parameters are interval-valued triangular fuzzy numbers and uses a novel optimization structure to find its optimal solution. The novelty of such an approach resides in requiring less computational effort compared to existing ones. The applicability of the proposed approach is illustrated through a numerical example. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

    Solving fully linear programming problem based on Z-numbers
    (Univ Sistan & Baluchestan, 2023) Joghataee, M.; Allahviranloo, T.; Lotfi, F. Hosseinzadeh; Ebrahimnejad, A.; Abbasbandy, S.; Amirteimoori, A.; Catak, M.
    Generally exploring the exact solution of linear programming problems in which all variables and parameters are Znumbers, is either not possible or difficult. Therefore, a few numerical methods to find the numerical solutions do act an important role in these problems. In this paper, we concentrate on introducing a new numerical method to solve such problems based on the ranking function. After proving the necessary theories, for more illustrations and the correctness of the topic, some theoretical and practical examples are also provided. Finally, the results obtained from the proposed method have been compared with some existing methods.
