responsibility in demand networks is one of the most important measures of performance. the concept of agility and flexibility in service and production. variety and changes in demand need more flexible network design that can cope with potential shortage and delay. this paper presents new mathematical model to optimize the design of demand network when there are highly variable demands. it als...

In this paper, we show how sustainable supply chains can be transformed into and studied as transportation networks. Specifically, we develop a new supply chain model in which the manufacturers can produce the homogeneous product in different manufacturing plants with associated distinct environmental emissions. We assume that the manufacturers, the retailers with which they transact, as well a...

The purpose of the paper is to present a hybrid algorithm to solve a transportation optimization model with random demand parameters and network design variables. At first, the classical deterministic linear transportation model with network design 0-1 variables is introduced. Then, randomness is considered for demand parameters and modeled by here-and-now approach. The obtained scenario-based ...

In this paper, we address a strategic planning problem for a three-stage productiondistribution network. The problem under consideration is a singleitem, multi-supplier, multi-producer and multi-distributor production-distribution network with deterministic demand. The objective is to minimize the costs associated with production, transportation and inventory as well as capacity expansion costs...

Rolling out of bed, José checks his CommuterAlert traveler information system while his coffee brews. The regional commuter assistance program was offering the system through a local automobile dealer when José purchased the family's vehicle. CommuterAlert is predicting that his 10-mile commute on I-275, which normally takes 29 minutes, will now take 46 to 52 minutes. In his printer are identif...

In the hope of supporting rural economies, some rural planners suggest fostering food processing firms in rural areas. Locating close to the source of necessary agricultural commodities might give the processors an advantage. However, emerging patterns of product innovations, which affect demand, and process innovations, which lower costs, are tied to firm-level capacities in research and devel...

Supply chains provide the critical infrastructure for the production and distribution of goods and services in our Network Economy and serve as the conduits for the manufacturing, transportation, and consumption of products ranging from food, clothing, automobiles, and high technology products, to even healthcare products. Cities as major population centers serve not only as the principal deman...

The stability of a user equilibrium determines whether it could be realized or sustained in a transportation network, when subject to perturbations in traffic conditions and drivers’ route choice behaviors. In this paper, with a simple deterministic dynamical system model of the traffic assignment problem, we first develop a systematic approach to analyzing asymptotic stability and instability ...
