A hybrid shifting bottleneck-tabu search heuristic for the job shop total weighted tardiness problem
In this paper, we study the job shop scheduling problem with the objective of minimizing the total weighted tardiness. We propose a hybrid shifting bottleneck tabu search (SB-TS) algorithm by replacing the reoptimization step in the shifting bottleneck (SB) algorithm by a tabu search (TS). In terms of the shifting bottleneck heuristic, the proposed tabu search optimizes the total weighted tardi...
Presently, most tabu search designers devise their applications without considering the potential of design and code reuse, which consequently prolong the development of subsequent applications. In this paper, we propose a software solution known as Tabu Search Framework (TSF), which is a generic C++ software framework for tabu search implementation. The framework excels in code recycling throu...
The use of optimization techniques has been recently proposed to build models for software development effort estimation. In particular, some studies have been carried out using search-based techniques, such as genetic programming, and the results reported seem to be promising. At the best of our knowledge nobody has analyzed the effectiveness of Tabu search for development effort estimation. T...
Economic load dispatch (ELD) is an important optimization task in power system. It is the process of allocating generation among the committed units such that the constraints imposed are satisfied and the energy requirements are minimized. There are three criteria in solving the economic load dispatch problem. They are minimizing the total generator operating cost, total emission cost and sched...
یکی از مهمترین نیازمندی های نسلهای آتی سیستمهای مخابرات سیار سلولی، تامین گذردهی (throughput) بالا جهت پشتیبانی از کاربردهایی است، که نرخ داده بالایی را بخصوص در ارتباط (لینک) مستقیم مطالبه می کنند. در ارتباط مستقیم یک سیستم سلولی، انتخاب پارامترهای ارسال مربوط به هر یک از کاربران هم-کانال، نه تنها در کیفیت ارتباط مربوط به آن کاربر خاص، بلکه در تمام ارتباطات (لینکهای) هم-کانال تاثیر می گذارد. ا...
Tourism industries are rapidly increased for the last few years especially in Malaysia. In order to attract more tourists, Malaysian Governance encourages any effort to increase Malaysian tourism industry. One of the efforts in attracting more tourists in Malacca, Malaysia is a duck tour. Duck tour is an amphibious sightseeing tour that works in two types of engines, hence, it required a huge c...
in this paper a non linear integrated fuzzy multi-objective production planning model with the labor learning and machines deterioration effects is presented. the objective function consists of two quantitative objectives namely increase profits and reduces the cost of system failure and a qualitative objective namely increases the satisfaction rate of the customers. different weights for objec...
In this paper we describe a scheduling problem for certain types of tournaments. It is formulated as a discrete minimization problem. Using a tabu search method we solve various problem instances of di erent size and complexity. The in uence of the tabu list size on the performance of the algorithm is studied. Tabu search is also compared with previous optimization techniques, which are availab...
This paper describes an automated tabu search based method for drawing general simple graph layouts with straight lines. To our knowledge, this is the first time tabu methods have been applied to graph drawing. We formulated the task as a multi-criteria optimization problem with a number of metrics which are used in a weighted fitness function to measure the aesthetic quality of the graph layou...
The application of Heuristic Search Methods for the earthquake resistant design of structural frames is discussed. The Tabu Search method was selected for application to structural weight optimization of steel moment frame structures. A computer program was developed that uses Tabu Search for weight minimization of two-dimensional framed structures. Written in the FORTRAN computer language, the...
