In this paper, we consider a scheduling problem simultaneously with rate-modifying activities and earliness and tardiness penalties on an unrelated parallel-machine setting. We assume that each machine has at most one rate-modifying activity to improve its production efficiency during the scheduling horizon and all the jobs have a common due-date. The objective is to determine jointly the optimal positions of rate-modifying activities, the optimal common due-date of all jobs, and the optimal schedule to minimize the sum of earliness and tardiness costs. We show that the problem can be optimally solved in polynomial time.

Max chart uses a single chart to control the process mean and variance. It performs with similar efficiency to joint and s charts. This study combined adaptive chart and Max chart to increase the detecting ability. A Markov chain approach was used to develop the statistical indicator and statistical design model of adaptive Max charts. This study designed adaptive Max charts to detect the mean shift and variance increase, and measured their performance for comparison with EWMA, CUSUM, and double-sampling charts. A comparison study revealed that the adaptive Max charts with variable parameter exhibited superior performance to detect the small shift than that of EWMA, CUSUM, and double sampling charts.

This article focuses on approach that provides visualization of machine–part clustering in cellular manufacturing system based on sequence of operation. We propose a novel cell formation approach, namely the growing hierarchical self-organizing map (GHSOM), for dealing with 14 benchmark problems from literature. The performance of the proposed algorithm is tested with the problem data sets and the results are compared using the group technology efficiency (GTE) and computational time with the existing traditional clustering algorithms. It is found that the proposed algorithm resulted in an increase in GTE in most of the problem data sets, and the outputs of cell formation are either superior or same as existing methods. The outputs of the experiments conducted in this research lead us to the conclusion that the GHSOM is a promising alternative cell formation algorithm owing to its adaptive architecture and the ability to expose the hierarchical structure of data.

This work considers scheduling problems minding the setup and removal times of jobs rather than processing times. For some production systems, setup times and removal times are so important to be considered independent of processing times. In general, jobs are performed according to the automatic machine processing in production systems, and the processing times are considered to be constant regardless of the process sequence. As the human factor can influence the setup and removal times, when the setup process is repetitive the setup times decreases. This fact is considered as learning effect in scheduling literature. In this study, a bi-criteria m-identical parallel machines scheduling problem with learning effects of setup and removal times is considered. The learning effect is proposed using a perceptron neural network algorithm. The objective function of the problem is minimization of the weighted sum of total earliness and tardiness. A mathematical programming model is developed for the problem, which is NP-hard. Results of computational tests show that the LINGO 9 software is effective in solving problems with up to 25 jobs and five machines. Therefore, for larger sized problems, a genetic algorithm for optimization is developed.

Estimating the variance of the sample mean is a classical problem of stochastic simulation. Traditional batch means estimators require specification of the simulation run length a priori. Dynamic batch means (DBM) is a new approach to implement the traditional batch means in fixed memory by dynamically changing both batch size and number of batches without the knowledge of the simulation run length. This article further improves the DBM by considering small storage requirements and fast computation. The proposed algorithm is useful when the simulation run length is random and extremely long in simulation models.

摘要 Greenwich and Jahr-Schaffrath(1995)提出一個製程能力弱度指標(process in capability index)稱為C pp 。指標C pp 是田口指標C pm 經由一個簡單的數學轉換而來。指標C pp 之優點爲其可以區分出製程的準確性(accuracy)與精確性（precision)，而且我們可以很容易得到指標C pp 的優良估計式。指標C pp 是一個簡易而且方便使用的績效評估工具。但是，因爲製程品質特性分佈之參數是未知而必須由樣本的資料來估計，其次才能得到指標的估計値，所以抽樣的誤差會導致指標估計値有很大的不確定性。因此只根據指標的估計値來判斷製程是否達到要求，會忽略了抽樣誤差因而不可靠。Cheng(1994)以及Pearn與Chen(1997)分別對指標C p 、C pm 及C pk 提供了一些可靠的方法評估製程的績效。本文則針對C pp 提供一個可靠的方法以評估製程的績效。

Lapping is a critical step of wafer manufacture. Some wafer quality characteristics, such as total thickness variation (TTV) and thickness, are largely determined by lapping. A lapping process has a collection of factors. In practice, some factors are seldom changed once been fixed; while some others are tuned online continuously. We classify the factors into online factors, offline factors, uncontrollable factors, and noises. In this work, we analyze the physical mechanism of lapping factors then conduct experiments to study the lapping process. Offline factors are optimized via the robust parameter design (RPD); online factors are optimized via the double exponential weighted moving average Run-to-Run control. Verifying experiments proved that the RPD and RtR control can help to improve the TTV and the batch-to-batch thickness variation, respectively.

Purpose: Magnetic Resonance Imaging is the most common tool used to diagnose supraspinatus muscle rupture or tear. However, discriminating the features between the rupture and the tear in MR images is difficult, and leads to low diagnostic accuracy. In this article, image enhancement techniques are performed on the original images to improve diagnostic performance. Methods: Three types of histogram-based image enhancement techniques are employed to enhance rotor cuff MR images: (1) histogram equalization; (2) weighted histogram separation (WHS); and (3) coupled WHS. The peak signal-to-noise ratio (PSNR) was used to evaluate the quality of the enhanced images. The experimental group comprises the enhanced images with the highest PSNR and the original MR images. The control group comprises only the original MR images. Both the control group and experimental group were randomly presented to three orthopedic physicians for performance evaluation. The accuracy rate and F-measure were applied to measure the average classification performance. The McNemar test was then employed to test the significance levels of the proposed enhancement techniques. Results: Experimental results showed the original MR image combined with the coupled WHS images (experimental group) outperforms the original MR image (control group) both in accuracy rate and F-measure. The McNemar test shows that the experimental group significantly outperforms the control group in terms of classifying the injury by type. Conclusion: A coupled WHS image enhancement technique was developed to assist the diagnosis of rotator cuff MR imaging by type. Experimental results showed that the proposed enhancement techniques improve the average diagnostic performance and facilitate the classification of the injury by type.

This study demonstrates optimization of sand casting process parameters using Taguchi's design of experiments method. The process parameters considered are moisture content, permeability, loss on ignition, compressive strength, volatile content, vent holes, pouring time, pouring temperature, and mold pressure. An attempt has been made to obtain optimal level of the process parameters in order to generate the optimum quality characteristics of the cast iron flywheel castings. An orthogonal array, the signal-to-noise ratio, and analysis of variance are used to analyze the effect of selected process parameters and their levels on the casting defects. The result indicates that the selected process parameters significantly affect the casting defects of cast iron flywheel castings. A confirmation run is used to verify the results, which indicates that this method is more efficient in determining the best casting parameters for flywheel castings.

This article investigates whether a glasses frame, which is symmetrically designed, can be used as an accessory to enhance an individual's facial attractiveness and the affective responses. We carry out a series of experiments using 16 prototypical glasses frame, each of which consists of different combinations of design features. The frames are fitted on one male and one female faces selected from the facial portraits of 200 university students. The participants rate the faces with and without wearing the glasses frames with the 7-point Likert scales on the included perceptual measures. The results show that wearing the glasses frames does generally improve facial symmetry. However, the facial attractiveness is not enhanced accordingly. Some designs such as the glasses frames with smaller rims have less impact on facial attractiveness than those with larger rims. To conclude, artificially improving the facial attractiveness requires more than just an enhancement of facial symmetry.
