چکیده

The road layout problem consists of finding a valid road layout between two locations described by their azimut and tridimensional coordinates in a topographical map. Valid layouts should comply with certain road design regulations that normally depend on design parameters such as road speed and type (e.g. highway, or conventional road). The paper presents a discrete state space for this problem that approximates real layouts, and discusses heuristic estimates that allow searching for the shortest approximation in such space using the A* heuristic search algorithm. These ideas have been implemented and tested in a road layout editor.

A bi-objective model for a scheduling problem of unrelated parallel batch processing machines with fuzzy parameters by two fuzzy multi-objective meta-heuristics

This paper considers a bi-objective model for a scheduling problem of unrelated parallel batch processing machines to minimize the makespan and maximum tardiness, simultaneously. Each job has a specific size and the data corresponding to its ready time, due date and processing time-dependent machine are uncertain and determined by trapezoidal fuzzy numbers. Each machine has a specific capacity,...

Two optimal algorithms for finding bi-directional shortest path design problem in a block layout

In this paper, Shortest Path Design Problem (SPDP) in which the path is incident to all cells is considered. The bi-directional path is one of the known types of configuration of networks for Automated Guided Vehi-cles (AGV).To solve this problem, two algorithms are developed. For each algorithm an Integer Linear Pro-gramming (ILP) is determined. The objective functions of both algorithms are t...

I/O Efficieny of Highway Hierarchies

Recently, Sanders and Schultes presented a shortest path algorithm, named Highway Hierarchies, for fast point-to-point shortest path queries. They report extremely quick average queries on the road network of USA. We consider the I/O efficiency of the algorithm and investigate how a good graph layout affects the average query time. We experiment with a few layout heuristics and obtain a speed-u...

Applying Genetic Algorithm to Dynamic Layout Problem

In today’s economy, manufacturing plants must be able to operate efficiently and respond quickly to changes in the product mix and demand.[1] Layout design has a significant impact on manufacturing efficiency. Initially, it was treated as a static decision but due to improvements in technology, it is possible to rearrange the manufacturing facilities in different scenarios. The Plant layout...
