Supply Chain: crisp and fuzzy aspects

Mohammad Fazel Zarandi, Ismail Türkşen, Soroosh Saghiri (2002)

International Journal of Applied Mathematics and Computer Science

Similarity:

This survey presents crisp and fuzzy models developed for the Supply Chain (SC). To this end, fuzzy concepts are first briefly reviewed. Then the structure of a supply chain system is explained. Recent challenges and ideas on these systems are also surveyed. Then, with reference to different aspects of an SC system, we classify the recent fuzzy models developed for different SC systems and compare them with related crisp models. Applications of the SC in manufacturing and service industries...

An approach to solve a fuzzy bi-objective multi-index fixed charge transportation problem

Maroua Hakim, Rachid Zitouni (2024)

Kybernetika

Similarity:

In this paper, we propose a novel approach for solving a fuzzy bi-objective multi-index fixed-charge transportation problem where the aim is to minimize two objectives: the total transportation cost and transportation time. The parameters of the problem, such as fixed cost, variable cost, and transportation time are represented as fuzzy numbers. To extract crisp values from these parameters, a linear ranking function is used. The proposed approach initially separates the main problem...
