“…Shin and Leon [33] developed a scheduling methodology for optimizing total tardiness and the number of families' set-up in TFT-LCD module processes. Shin and Kang [34] proposed a dispatching algorithm focused on rework processes named greedy rework probability with due-dates (GRPD). Choi and Seo [13] addressed finite-capacity planning (medium-term schedules) issues in a LCD flow line and presented capacity-filtering algorithms for generating a finite-capacity loading-profile from an infinite-capacity loading profile.…”

“…In addition, Huang pointed out the following four factors which influence Taiwan's TFT-LCD industry strategy in the competitive environment (Lin et al 2006): government policy, human resources, capital investment, and bridging institution. Also Shin and Kang (2010) proposed a rework-based dispatching algorithm to improve the productivity for module process in TFT-LCD manufacture. Also, Chen et al (2008) proffered a statistical process control (SPC) method to evaluate the LCD industry performance, while Hsieh (2008) proposed a method incorporating fuzzy adaptive resonance theory and a stepwise regression approach for the clustering analysis on the abnormal position defect status in TFT-LCD process to increase the production performance.…”

This study proposes a genetic algorithm (GA)-based Material Handling Strategy Function (MHSF) method to increase the productivity of a TFT-LCD array fabrication to improve the traditional FIFO method in TFT-LCD fabrication by the reduction of the material handling for a Rail Guided Vehicle (RGV), because costs of material handling count up to about 50% of production costs. In this article, the MHSF is provided to help material handling commands choice, where a novel GA approach is used to adapt the weights of affecting factors in the function. Finally, to evaluate the performance of the proposed method, experiments using the data from a major TFT-LCD manufacturing plant in Taiwan have been carried out, and the results indicate that it can indeed reduce fabrication time and increase productivity.

“…Shin and Leon (2004) developed two algorithms based on the MULTIFIT method and tabu search to solve the parallel machine-scheduling problem with family setup times and due dates in TFT-LCD module factories. Shin and Kang (2010) proposed a dispatching algorithm for rework processes in TFT-LCD module factories, and measured its performance by six diagnostic indicators. Wang et al (2007) considered a variety of important factors of resource planning to propose a genetic algorithm to solve the resource portfolio problem in semiconductor testing markers.…”

The thin flim transistor liquid crystal display (TFT-LCD) module factories are in charge of the last process of the TFT-LCD supply chain, i.e., assembling LCD panels (produced from the former process in the supply chain) as well as electronic components into TFT-LCD panels or the finished products using TFT-LCD panels. Since the variation of machine processes and production techniques at the former process of the supply chain results in a variety of qualities of LCD panels, the finished products assembled with those LCD panels of different qualities are also of different qualities, according to which they are classified into different grades. This paper models the material allocation system for a TFT-LCD module factory based on the make-to-stock (MTS) production, in which one of the main designs is to allow the flexibility that the finished products of higher grades are able to be downgraded to respond to the drastic variation of customer requirements for each grade of finished products. The system is modelled in detail by an integer programming approach that takes into account not only downgraded products but also the customer requirements for the quality qualification rate and the lower bound of * A preliminary version of this work was presented at non-dot-defect rate of products, to maximize the total profit of the product portfolio. The model is evaluated by conducting an experimental study for a numerical example, which turns out that the proposed system looks promising as it determines a feasible product portfolio that decreases both the inventory of LCD panels and the volume of unqualified products while maintaining a high profit.Keywords: TFT-LCD; material allocation; downgraded product; quality qualification rate; lower bound of non-dot-defect rate.
