This paper deals with inventory sharing in the context of a decentralized supply chain. The chain consists manufacturer who distributes set products through network independents Points Sale (POS). primary decision each player has to make is optimize its service level while maintaining minimum total cost. POS share their allowing transshipment enhance ability face demand and avoid shortages. pro...

the fuzzy linear regression model with fuzzy input-output data andcrisp coefficients is studied in this paper. a linear programmingmodel based on goal programming is proposed to calculate theregression coefficients. in contrast with most of the previous works, theproposed model takes into account the centers of fuzzy data as animportant feature as well as their spreads in the procedure ofconstr...

This paper considers the transportation of prefabricated products in construction industry. Prefabricated can be transported by road transport or intermodal transport, latter which incurs lower carbon emissions. A contractor always selects mode with a cost rather than one emission. bi-level programming model was formulated to decide optimal subsidy for achieve lowest emissions while accounting ...

In this paper, we have proposed an algorithm to solve bi-level linear programming problems with fuzzy parameters without converting it to crisp equivalent problem and obtained a fuzzy compromise solution. Since the decision variables and objective functions are represented as fuzzy membership functions, the proposed fuzzy compromise solution will be more practical and reasonable. A numerical ex...

in this paper, a mathematical method is proposed to formulate a generalized ordering problem. this model is formed as a linear optimization model in which some variables are binary. the constraints of the problem have been analyzed with the emphasis on the assessment of their importance in the formulation. on the one hand, these constraints enforce conditions on an arbitrary subgraph and then g...
