Efficient Simulations of Supply Chains
نویسندگان
چکیده
High volume production flows are modeled by nonlinear hyperbolic partial differential equations representing conservation laws. These models have Little’s law explicitly built into the formulation. Borrowing from concepts in gas dynamics and vehicular traffic models we derive several prototypical equations representing linear as well as reentrant factories. Multiple products, dispatch polices and control actions can be modeled. Standard hydrodynamic codes provide very fast simulations of these models allowing us to link them together to form efficient supply chain simulations.

An efficient Imperialistic Competitive Algorithm for the closed-loop supply chains considering pricing for product, and fleet of heterogeneous vehicles
This paper investigates a pricing multi-period, closed-loop supply chains (CLSCs) with two echelons of producers and customers. Products are delivered to customers might be defective which are picked up and gathered in the collection center and will be fixed if it is possible and will be returned to the chain. Otherwise, they are sold as waste. This problem is determining price and distributio...
متن کاملDeterministic and Metaheuristic Solutions for Closed-loop Supply Chains with Continuous Price Decrease
In a global economy, an efficient supply chain as a main core competency empowers enterprises to provide products or services at the right time in the right quantity, at a low cost. This paper is to plan a single product, multi-echelon, multi-period closed loop supply chain for high-tech products (which have continuous price decrease). Ultimately, considering components rated to procurement, pr...

Social responsibility is a key factor that could result in success and achieving great benefits for supply chains. Responsiveness and reliability are important social responsibility measures for consumers and all stakeholders that strategists and company managers should be concerned about them in long-term planning horizon. Although, presence of uncertainties as an intrinsic part of supply chai...
متن کاملApplying Stackelberg Game to Find the Best Price and Delivery Time Policies in Competition between Two Supply Chains
In this paper, the competition between two supply chains and their elements is studied. Each chain consisted of a manufacturer and a distributor and the two chains compete in a market with single type of customer sensitive to price and delivery time. Therefore, this is a two-supply chain game and during the competition between two supply chains, elements of each supply chain (manufacturer and/o...
