Data Envelopment Analysis (DEA) is one of the best-known efficiency evaluation methods due to its advantages in selection of weights. Many research papers have extensively discussed the issue of weight restrictions, rather than those implied in the model itself. However, this often leads to a failure to represent the relations of certain weights, as well as(More)

The Theory of Constraints (TOC) Simplified Drum-Buffer-Rope (SDBR) system works effectively in typical job shop environments. However, according to the experiences implementing SDBR(More)
Data envelopment analysis (DEA) is a representative method to estimate efficient frontiers and derive efficiency. However, in a situation with weight restrictions on individual input–output pairs, its suitability has been questioned. Therefore, the main purpose of this paper is to develop a mathematical method, which we call the input-oriented ratio-based(More)
Assembly planning attempts to arrange product assembly sequences on the basis of the input of product description, similar assembly plans and assembly constraints. Assembly planning is frequently viewed as a creative thinking process, which requires extensive assembly planning experience. Assembly product modeling with mechanical connection functions has(More)
This study presents a novel Adaptive resonance theory-Counterpropagation neural network (ART-CPN) for solving forecasting problems. The network is based on the ART concept and the CPN learning algorithm for constructing the neural network. The vigilance parameter is used to automatically generate the nodes of the cluster layer for the CPN learning process.(More)
Because of the unreasonable and unnecessary weight restriction assumption, a barely noticeable deficiency in pseudo-inefficiency occurs at times when applying a CCR model. The CCR was the first model designed for Data Envelopment Analysis (DEA); it remains its most popular model. To detect this type of unobvious deficiency, this study compared the(More)
The corporate competitive environment is being liberalized and globalized, therefore product life cycle is shortening. Markets are undertaking globalization and because of rapid changes in recent years, companies need to act more responsively to the market and customer demand as well as strengthen information exchange and communication systems in order to(More)
Even though having gained further insight into dispatching problems involving wafer fabrication, previous research cannot optimize the three global performances (Throughput, Cycle Time and Work-InProcess) simultaneously. To overcome the conflicts among these three performance factors, we present a dispatching decision method for the wafer fabrication(More)
