[ 1 ] - Fuzzy multi-objective assembly line balancing problem: Fuzzy mathematical programming approach
Design of assembly line is done in order to more coordinate a collection of some consecutive work stations for the aim of obtaining more productivity from the work stations and workers. The stations are arranged in a way to have a continuous and constant material flow. In this paper a multi-objective formulation for assembly line balancing is introduced. As a solution approach a two-step approa...
[ 2 ] - An Approximation Method for Fuzzy Fixed-Charge Transportation Problem
In this paper, we develop the fuzzy fixed charge transportation problem when the costs are the fuzzy numbers. The first step it transform into the classical fuzzy transportation problem. The next, we obtain the best approximation fuzzy on the optimal value of the fuzzy fixed-charge transportation problem. This method obtains a lower and upper bounds both on the fuzzy optimal value of the fuzzy ...
[ 3 ] - Supply chain network design with multi- mode demand based on acceptance degree of fuzzy constraints violated
This paper designs a mathematical model for supply chain network design problem including plants, distributors and customers in fuzzy environment. Each plant and distributor has several levels capacities. A multi-mode demand strategy is considered for the customers where only one of the modes is to be selected for each customer. Considering the acceptance degree of fuzzy constraints violated, a...
[ 4 ] - Designing a model for evaluating the financial performance of petrochemical companies based on Grounded theory
The purpose of this study was to develop a model for evaluating the financial performance of petrochemical companies. The methodology of the research was exploratory in terms of purpose and mixed (quantitative-qualitative) in terms of data collection method. 200 experts and engineers working in petrochemical companies were available by sampling method. To achieve the objectives of the research...
[ 5 ] - Identifying and Prioritizing Sustainable Outsourcing Risk with Fuzzy Type II Data (Case Study: National Company for Southern Oilfields)
The purpose of this research is Identifying and Prioritizing Sustainable Outsourcing Risk with Fuzzy Type II Data in National Company for Southern Oilfields. This research was a Mix methodology and used qualitative and quantitative analytical processes to collect and analyze data. In the qualitative part, meta-analysis was first used to identify its components and themes to assess the risk of s...
