This paper studies a problem of controlling trajectories of a platoon of vehicles on a highway section with advanced connected and automated vehicle technologies. This problem is very complex because each vehicle trajectory is essentially an infinite-dimensional object and neighboring trajectories have complex interactions (e.g., car-following behavior). A parsimonious shooting heuristic algori...

We consider the post-disaster road clearing problem with the goal of restoring network connectivity in shortest time. Given a set of blocked edges in the road network, teams positioned at depot nodes are dispatched to open a subset of them that reconnects the network. After a team finishes working on an edge, others can traverse it. The problem is to find coordinated routes for the teams. We ge...

Efficient constructive heuristics have been designed for most of the difficult combinatorial optimisation problems. Performance of these heuristics may vary from one instance to another and hence it is beneficial to be able to select an instance of the heuristic which is best suited to a given instance of the problem. Both of the heuristic search algorithm and hyper-heuristic approaches try to ...

Recent systems applying Machine Learning (ML) to solve the Traveling Salesman Problem (TSP) exhibit issues when they try scale up real case scenarios with several hundred vertices. The use of Candidate Lists (CLs) has been brought cope issues. A CL is defined as a subset all edges linked given vertex such that it contains mainly are believed be found in optimal tour. initialization procedure id...

the problem of lot sizing, sequencing and scheduling multiple products in flow line production systems has been studied by several authors. almost all of the researches in this area assumed that setup times and costs are sequence –independent even though sequence dependent setups are common in practice. in this paper we present a new mixed integer non linear program (minlp) and a heuristic meth...

The uniform capacitated vertex k -center problem is an \(\mathcal {NP} \) -hard combinatorial optimization that models real situations where centers can only attend a maximum number of customers, and the travel time or distance from customers to their assigned center has be minimized. This paper introduces polynomial-time constructive heuristic algorithm exploits relationship between this minim...
