Analyses of serial production line systems for interdeparture time variability and WIP inventory systems
(International Journal of Operations and Quantitative Management, 2004)This paper investigates the well-known and extensively studied unpaced production line problem for the interdeparture time variability and work-in-process (WIP) inventory. The primary objective is to examine the relationships ... -
Analysis of assembly systems for interdeparture time variability and throughput
(Taylor & Francis, 2002)This paper studies the effect of the number of component stations (parallelism), work transfer, processing time distributions, buffers and buffer allocation schemes on throughput and interdeparture time variability of ... -
Analysis of serial production lines: Characterisation study and a new heuristic procedure for optimal buffer allocation
(Taylor & Francis, 2006)Buffer allocation in serial production lines is one of the important design issues, and hence it has been studied extensively in the literature. In this paper, we analyse the problem to characterise the optimal buffer ... -
Ant colony optimization for the single model U-type assembly line balancing problem
(Elsevier, 2009)An assembly line is a production line in which units move continuously through a sequence of stations. The assembly line balancing problem is defined as the allocation of tasks to an ordered sequence of stations subject ... -
Assembly line balancing using genetic algorithms
(Kluwer Academic Publishers, 2000)Assembly Line Balancing (ALB) is one of the important problems of production/operations management area. As small improvements in the performance of the system can lead to significant monetary consequences, it is of utmost ... -
Backtracking and exchange of information: methods to enhance a beam search algorithm for assembly line scheduling
(Elsevier, 2008)Beam search (BS) is used as a heuristic to solve various combinatorial optimization problems, ranging from scheduling to assembly line balancing. In this paper, we develop a backtracking and an exchange-of-information (EOI) ... -
Balancing of U-type assembly systems using simulated annealing
(Taylor & Francis, 2001)The paper presents a new simulated annealing (SA)-based algorithm for the assembly line-balancing problem with a U-type con®guration. The proposed algorithm employs an intelligent mechanism to search a large solution space. ... -
Batch scheduling to minimize the weighted number of tardy jobs
(Pergamon Press, 2007)In this paper, we address a single-machine scheduling problem with due dates and batch setup times to minimize the weighted number of tardy jobs. We give a pseudo-polynomial dynamic program and a fully-polynomial approximation ... -
Binary integer formulation for mixed-model assembly line balancing problem
(Pergamon Press, 1998-04-01)The assembly line balancing problem has been a focus of interest to the academicians of production/operations management for the last 40 years. Although there are numerous studies published on the various aspects of the ... -
Coordination of staffing and pricing decisions in a service firm
(John Wiley & Sons, 2008)Customer demand is sensitive to the price paid for the service in many service environments. Using queueing theory framework, we develop profit maximization models for jointly determining the price and the staffing level ... -
Customer order scheduling on a single machine with family setup times: complexity and algorithms
(Elsevier, 2007)We consider a situation where C customers each order various quantities (possibly zero in some cases) of products from P different families, which can be produced on a continuously available machine in any sequence (requiring ... -
Customer order scheduling problem: a comparative metaheuristics study
(Springer, 2007)The customer order scheduling problem (COSP) is defined as to determine the sequence of tasks to satisfy the demand of customers who order several types of products produced on a single machine. A setup is required whenever ... -
Discrete time/cost trade-off problem: a decomposition-based solution algorithm for the budget version
(Pergamon Press, 2010-04)This paper investigates the budget variant of the discrete time/cost trade-off problem (DTCTP). This multi-mode project scheduling problem requires assigning modes to the activities of a project so that the total completion ... -
Distribution of quality costs: evidence from an aeronautical firm
(Routledge, 2000)In this paper we discuss quality cost categories and their distribution in the total quality cost. We also present a taxonomy of the various quality cost terms. A case study is performed in a project-oriented company in ... -
The effect of continuous price change in the EOQ
(Pergamon Press, 1992)The sensitivity of the basic economic order quantity (EOQ) model to continuous purchase price changes is explored. The phenomenon of continuous price changes exists in several countries and it is not likely to improve. The ... -
Effect of discrete batch WIP transfer on the efficiency of production lines
(Taylor & Francis, 1993)In this paper, the effect of discrete batch transfer of WIP between workstations on the efficiency of asynchronous production lines is analysed via a simulation model. The processing times are assumed to be random variables ... -
FPTAS for half-products minimization with scheduling applications
(Elsevier, 2008)A special class of quadratic pseudo-boolean functions called "half-products" (HP) has recently been introduced. It has been shown that HP minimization, while NP-hard, admits a fully polynomial time approximation scheme ... -
A goal programming approach to mixed-model assembly line balancing problem
(Elsevier, 1997)In this paper, a binary goal programming model for the mixed-model assembly line balancing (ALB) problem is developed. The model is based on the concepts developed by Patterson and Albracht [1] and the model of Deckro and ... -
ISO 9000 implementation in Turkish industry
(Emerald, 1997)Notes that it has become a competitive necessity for firms doing business globally to acquire the ISO 9000 certification, despite the misgivings many have with regard to its true effectiveness. Turkey, an emerging industrial ... -
A methodology for solving single-model, stochastic assembly line balancing problem
(Pergamon Press, 1999)In this paper, a methodology is developed to solve the single-model, stochastic assembly line balancing problem for the objective of minimizing the total labor cost and the expected incompletion cost arising from tasks not ...
