Critical infrastructure resilience has become a national priority for the U.S. Department of Homeland Security. Rapid and efficient restoration of service in damaged transportation networks is a key area of focus. The intent of this paper is to formulate a bi-level optimization model for network recovery and to demonstrate a solution approach for that optimization model. The lower-level problem...

But beginning with his work in the late 1970s, Sosa takes a different approach to the debate between foundationalists and coherentists over the structure of knowledge. (Indeed, Sosa takes this different approach to a number of long-standing disputes in philosophy.) Rather than assuming the sides are talking past one another, Sosa suggests that each side has identi fi ed part of the truth, but m...

Purpose The purpose of this paper is to optimize the design charging station deployed at terminal for electric transit, with explicit consideration heterogenous modes. Design/methodology/approach authors proposed a bi-level model decision-making both tactical and operational levels simultaneously. Specifically, level (i.e. lower level), service schedule recharging plan buses are optimized under...

nowadays, different methods are used to solve optimization problems which ,one of the newest is bco method that are inspired by the nature and derived from the social life of bees of these methods can be noted that bco is derived from the social life of bees. we use in this paper fuzzy logic for bee‟s decision stage. at the end, we solve two different problem that have already been solved by es...

Decentralized supply chain management is found to be significantly relevant in today’s competitive markets. Production and distribution planning is posed as an important optimization problem in supply chain networks. Here, we propose a multi-period decentralized supply chain network model with uncertainty. The imprecision related to uncertain parameters like demand and price of the final produc...
