Multi-Cast Ant Colony System for Bus Routing Problem

چکیده
This paper investigates a routing problem in a public transportation network, more precisely — the problem of finding an optimal journey plan in the Silesian Bus Network, given a timetable. In our previous experiments we analysed the Ant System which was adapted to the Bus Routing Problem (BRP) [1]. Numerical experiments have shown that the evaluation function applied caused many difficulties and the system performance was unsatisfactory. At this time we try to improve the system achievement including the idea of Multi-Cast Ant Colony System (MCACS).

Ant Colony Algorithm for the Single Loop Routing Problem
In this paper, a new algorithm for solving the single loop routing problem is presented. The purpose of the single loop routing problem(SLRP) is to find the shortest loop for an automated guided vehicle covering at least one edge of each department of a block layout. First it shown that this problem can be represented as a graph model. Then a meta-heuristic algorithm based on and colony system ...

In this paper, a multi-objective reconfiguration problem has been solved simultaneously by a modified ant colony optimization algorithm. Two objective functions, real power loss and energy not supplied index (ENS), were utilized. Multi-objective modified ant colony optimization algorithm has been generated by adding non-dominated sorting technique and changing the pheromone updating rule of ori...

متن کاملSolving the vehicle routing problem by a hybrid meta-heuristic algorithm
The vehicle routing problem (VRP) is one of the most important combinational optimization problems that has nowadays received much attention because of its real application in industrial and service problems. The VRP involves routing a fleet of vehicles, each of them visiting a set of nodes such that every node is visited by exactly one vehicle only once. So, the objective is to minimize the to...
متن کاملSolving the Vehicle Routing Problem with Simultaneous Pickup and Delivery by an Effective Ant Colony Optimization
One of the most important extensions of the capacitated vehicle routing problem (CVRP) is the vehicle routing problem with simultaneous pickup and delivery (VRPSPD) where customers require simultaneous delivery and pick-up service. In this paper, we propose an effective ant colony optimization (EACO) which includes insert, swap and 2-Opt moves for solving VRPSPD that is different with common an...
