A computationally simple approach (i.e., the PSK method) for solving fully intuitionistic fuzzy real-life transportation problems

This article proposes the PSK method for finding the optimal objective value for a FIFTP in one stage using the newly proposed TrIFN multiplication operation. The PSK method is computationally simple and easy to understand. The physically meaningful objective value is also obtained in this method.

More details on this study can be found in our recent article "Computationally simple approach for solving fully intuitionistic fuzzy real life transportation problems" published in International Journal of System Assurance Engineering and Management (https://doi.org/10.1007/s13198-014-0334-2).

In tackling real-world transportation problems, people frequently encounter uncertainty and hesitancy due to a variety of unpredictable factors. So, to deal with impreciseness and reluctance, numerous authors have proposed an intuitionistic fuzzy representation of the data. So, in this study, the authors look at a transportation problem with uncertainty and reluctance in all its parameters. The authors outline the issue and use triangular intuitionistic fuzzy numbers (TrIFNs) to address uncertainty and hesitation. The authors offer a new method, the PSK method, for finding the intuitionistic fuzzy optimal solution to the fully intuitionistic fuzzy transportation (FIFTP) issue in one stage. Additionally, a novel multiplication operation on TrIFN is presented to determine the minimum objective value in terms of TrIFN. In actual life, the type-4 IFTP has a wide range of uses, including satellite/missile launch and oil delivery. So there is no question that this article will fascinate everyone if they read it.

The fundamental advantage of this method is as follows:

  1. Computationally simple and easy to understand
  2. It gives physically meaningful objective function value
  3. It is a one-stage method
  4. It is independent of the initial solution
  5. It has a smaller number of steps
  6. It solves the real-life problem
  7. The PSK method is efficient and always gives optimal solutions. Since the authors have theoretically demonstrated it.

In the literature, the author P. Senthil Kumar (PSK) originally divided IFTPs into four categories, namely, type-1, 2, 3, and 4. He solved all four types of problems using various methods with software, including the PSK method. This article deals with full/type-4 IFTP. Studying IFTP is better than studying fuzzy transportation problems (FTPs)1, 2. From the FTPs, we can determine the acceptance of the transportation cost, but we cannot determine the degree of non-acceptance and degree of hesitation of the transportation cost3, 4. For more details, see here5.

In our day-to-day lives, there is a need to ship commodities from various factories to various warehouses6. Understanding the transportation issue is critical to effectively managing this situation. However, transportation cost, demand, and supply are not exact values due to unpredictable circumstances7, 8. As a result, resolving transportation issues with intuitionistic fuzzy number is more critical. So, this work effectively resolves the type-4 IFTP. We can read about comparable situations with different approaches and different constraints here9, 10. Table 1 compares the proposed study to existing literature.
