indicators for quality improvability and bottleneck sequence in Flexible Manufacturing Systems with batch production
International Journal of Production Research, 2012Co-Authors: Junwen Wang, Jorge Arinez, Stephan BillerAbstract:In this paper we study product quality in Flexible Manufacturing Systems with batch production using a Markov chain model. To improve the quality performance in such Systems, the notions of quality improvability and bottleneck sequence are introduced. Indicators for identifying the quality improvability and bottleneck sequence, based on data measured on the factory floor rather than complicated calculations, are developed. A case study of improving quality at an automotive paint shop is introduced.

Product Sequencing With Respect to Quality in Flexible Manufacturing Systems With Batch Operations
IEEE Transactions on Automation Science and Engineering, 2010Co-Authors: Junwen Wang, Jorge Arinez, Stephan BillerAbstract:In many Flexible Manufacturing Systems, batch production is often adopted to improve product quality. For example, in automotive paint shops, vehicles with same colors are typically grouped into small batches to reduce quality degradation and purge cost due to color change. In this paper, we present an analytical method to evaluate the quality performance of Flexible Manufacturing Systems with batch operations. In addition, we investigate the impact of product sequencing and batch policies on product quality and present some insights to achieve better quality using these policies.

CASE - Monotonic and non-monotonic properties of product quality in Flexible Manufacturing Systems with batch operations
2009 IEEE International Conference on Automation Science and Engineering, 2009Co-Authors: Junwen Wang, Jorge Arinez, Stephan Biller, Ningjian HuangAbstract:Many Flexible Manufacturing Systems implement batch production, in order to shorten changeover time, reduce cost, and improve quality. In such Systems, different types of products are grouped into batches where all parts in each batch have the same type. The change of product type only occurs after the last job in a batch is processed. In this paper, we present an analytical method to evaluate the quality performance of Flexible Manufacturing Systems with batch operations and investigate the monotonic and non-monotonic properties of product quality with respect to quality failure and repair probabilities and batch sizes.

scheduling Flexible Manufacturing Systems using petri nets and heuristic search
International Conference on Robotics and Automation, 1994Co-Authors: Doo Yong Lee, F DicesareAbstract:Petri net modeling combined with heuristic search provides a new scheduling method for Flexible Manufacturing Systems. The method formulates a scheduling problem with a Petri net model. Then, it generates and searches a partial reachability graph to find an optimal or near optimal feasible schedule in terms of the firing sequence of the transitions of the Petri net model. The method can handle features such as routing flexibility, shared resources, lot sizes and concurrency. By following the generated schedule, potential deadlocks in the Petri net model and the system can be avoided. Hence the analytical overhead to guarantee the liveness of the model and the system is eliminated. Some heuristic functions for efficient search are explored and the experimental results are presented. >

Flexible Manufacturing Systems modelling and performance evaluation using automod
International Journal of Simulation Modelling, 2011Co-Authors: B S P Reddy, C S P RaoAbstract:In recent times Flexible Manufacturing Systems emerged as a powerful technology to meet the continuous changing customer demands. Increase in the performance of Flexible Manufacturing Systems is expected as a result of integration of the shop floor activities such as machine and vehicle scheduling. The authors made an attempt to integrate machine and vehicle scheduling with an objective to minimize the makespan using Automod. Automod is a discrete event simulation package used to model and simulate a wide variety of issues in automated Manufacturing Systems. The key issues related to the design and operation of automated guided vehicles such as flow path layout, number of vehicles and traffic control problems are considered in the study. The performance measures like throughput, machine and vehicle utilization are studied for different job dispatching and vehicle assignment rules in different Flexible Manufacturing system configurations.

the diffusion of Flexible Manufacturing Systems in japan europe and the united states
Management Science, 1993Co-Authors: Edwin MansfieldAbstract:This paper is concerned with the rate of diffusion of Flexible Manufacturing Systems, one of the most important industrial applications of information technology. Using data from about 175 firms, I analyze diffusion rates in Japan, Western Europe and the United States, a major purpose being to determine whether, as is often claimed, U.S. firms have been relatively slow to introduce this innovation, and if so, why.

Flexible Manufacturing Systems
Japan and the World Economy, 1992Co-Authors: Edwin MansfieldAbstract:Abstract This paper presents and analyzes detailed data obtained from over 200 firms in Japan, the United States, and Western Europe concerning the economic effects of Flexible Manufacturing Systems, and compares the effectiveness and profitability of these Systems in various countries. Such a comparison should be of widespread interest, particularly since some leading American experts, like Jaikumar (1986), have charged that Japanese firms use their Flexible Manufacturing Systems much more effectively than do their U.S. rivals.
