Evaluating Downside Risks in Reliable Networks
(2011-05-27)
Reliable networks are those in which network elements have a positive probability of failing. Conventional performance measures for such networks concern themselves either with expected network performance or with the ...
Speeding Up the Estimation of Expected Maximum Flows through Reliable Networks
(2011-05-27)
This paper presents a strategy for speeding up the estimation of expected maximum flows through reliable networks. Computational experiments with the strategy on three types of randomly generated networks show that it ...
Exploring lin kernighan neighborhoods for the indexing problem
(Indian Institute of Management Ahmedabad, 2016-02-29)
The indexing problem in automated machining environments aims to arrange tools in tool slots of a tool magazine for faster processing of jobs. This problem is called the indexing problem and has been widely studied in the ...
Allocating tools to index positions in tool magazines using tabu search
(Indian Institute of Management Ahmedabad, 2016-02-13)
The arrangement of tools in tool slots of a tool magazine is an important problem in automated machining environments. This problem is called the indexing problem and has been widely studied in the literature. In this paper ...
Comparing genetic algorithm crossover and mutation operators for the indexing problem
(Indian Institute of Management Ahmedabad, 2016-03-18)
The tool indexing problem is one of allocating tools to slots in a tool magazine so as to minimize the tool change time in automated machining. Genetic algorithms have been suggested in the literature to solve this problem, ...
A new genetic algorithm for the tool indexing problem
(Indian Institute of Management Ahmedabad, 2016-03-14)
The tool indexing problem is one of allocating tools to slots in a tool magazine so as to minimize the tool change time in automated machining. This problem has been widely studied in the literature. A genetic algorithm ...
Incorporating gender and age in genetic algorithms to solve the indexing problem
(Indian Institute of Management Ahmedabad, 2016-04-04)
In this paper we propose new genetic algorithms for the tool indexing problem. Genetic algorithms are said to be nature-inspired, in that they are modeled after the natural process of genetic evolution. The evolution process ...
A Quadratic Programming Formulation of the Equidistant Bi-directional Loop Layout Problem
(Indian Institute of Management Ahmedabad, 2015)
A loop layout is a common layout used in flexible manufacturing. In such a layout, a set of stations or facilities are to be arranged in a closed loop so that the total cost of flow between each pair of facilities is ...
Tabu search for multi-period facility location: uncapacitated problem with an uncertain number of servers
(Indian Institute of Management Ahmedabad, 2014)
This paper supersedes the work presented in WP.No.2014-02-06. We study the problem of allocating doctors to primary health centers (PHC). We model the problem as a multi-period uncapacitated facility location problem under ...
Speeding up neighborhood search for the tool indexing problem
(Indian Institute of Management Ahmedabad, 2016)
The arrangement of tools in tool holding pockets of a tool magazine in a CNC machining center plays an important role in reducing processing times of complex job processes in automated machining environments. This problem ...
