Product agile customization design is an effective technological measure to win the customers and improve development efficiency. It needs designer to determine product structure quickly according to customer’s customized requirements. In this paper, a novel design method of product agile customization is presented by integrating rough set (RS) theory and artificial neural network (ANN) in the design process. In the method, design demands are reduced so as to form effective decision conditions by applying RS, and on that basis ANN models between design demands of different design stages and corresponding product structures are established so as to determine product structural styles quickly by applying ANN. Finally, this method is applied to the general schematic design process of a roll plate machine’s customization, and its validity is verified.

In this study, three artificial neural network (ANN) models are developed with back propagation (BP) optimization algorithms to predict various lightning damage modes in carbon/epoxy laminates. The proposed ANN models use three input variables associated with lightning waveform parameters (i.e., the peak current amplitude, rising time, and decaying time) to predict fiber damage, matrix damage, and through-thickness damage in the composites. The data used for training and testing the networks was actual lightning damage data collected from peer-reviewed published literature. Various BP training algorithms and network architecture configurations (i.e., data splitting, the number of neurons in a hidden layer, and the number of hidden layers) have been tested to improve the performance of the neural networks. Among the various BP algorithms considered, the Bayesian regularization back propagation (BRBP) showed the overall best performance in lightning damage prediction. When using the BRBP algorithm, as expected, the greater the fraction of the collected data that is allocated to the training dataset, the better the network is trained. In addition, the optimal ANN architecture was found to have a single hidden layer with 20 neurons. The ANN models proposed in this work may prove useful in preliminary assessments of lightning damage and reduce the number of expensive experimental lightning tests.

For hospitals’ admission management, the ability to predict length of stay (LOS) as early as in the preadmission stage might be helpful to monitor the quality of inpatient care. This study is to develop artificial neural network (ANN) models to predict LOS for inpatients with one of the three primary diagnoses: coronary atherosclerosis (CAS), heart failure (HF), and acute myocardial infarction (AMI) in a cardiovascular unit in a Christian hospital in Taipei, Taiwan. A total of 2,377 cardiology patients discharged between October 1, 2010, and December 31, 2011, were analyzed. Using ANN or linear regression model was able to predict correctly for 88.07% to 89.95% CAS patients at the predischarge stage and for 88.31% to 91.53% at the preadmission stage. For AMI or HF patients, the accuracy ranged from 64.12% to 66.78% at the predischarge stage and 63.69% to 67.47% at the preadmission stage when a tolerance of 2 days was allowed.

Abstract This paper proposes a method, namely MDKS (Kennard-Stone algorithm based on Mahalanobis distance), to divide the data into training and testing subsets for developing artificial neural network (ANN) models. This method is a modified version of the Kennard-Stone (KS) algorithm. With this method, better data splitting, in terms of data representation and enhanced performance of developed ANN models, can be achieved. Compared with standard KS algorithm and another improved KS algorithm (data division based on joint x - y distances (SPXY) method), the proposed method has also shown a better performance. Therefore, the proposed technique can be used as an advantageous alternative to other existing methods of data splitting for developing ANN models. Care should be taken when dealing with large amount of dataset since they may increase the computational load for MDKS due to its variance-covariance matrix calculations.

Data mining menjadi topik hangat yang sangat bermanfaat di era saat ini. Sistem Artificial Neural Network (ANN) dan rough set yang merupakan metode data mining dapat digabungkan yang selanjutnya disebut sebagai metode Rough Neural Network (RNN). Siste, roughset dalam RNN berfungsi untuk mereduksi atribut untuk optimalisasi informasi sedangkan ANN berfungsi untuk membentuk jaringan dari kumpulan data reduksi tersebut. Metode ini dapat digunakan di berbagai bidang misalnya bisnis yakni dalam mengidentifikasi kepuasan konsumen. Perlindungan hak maupun kewajiban dalam bisnis adalah hal penting di negara maju, contohnya New York yang telah membentuk Departement of Consumen Affairs (DCA). Ribuan mediasi tercatat telah dilakukan oleh DCA New York sehingga pendekatan struktur terhadap kepuasan konsumen merupakan hal penting dalam meninjau apakah layanan mediasi yang dilakukan telah baik. Oleh karena itu, tujuan penelitian ini adalah mengimplementasikan metode RNN pada suatu dataset komplain konsumen terhadap pelayanan mediasi DCA New York. Hasil penelitian pada proses awal, rough set menunjukkan bahwa atribut yang efektif untuk menghasilkan kepuasan konsumen yang optimal adalah atribut Business State, Complaint Result, Duration of Mediation, dan Complaint Type. Eror yang dihasilkan pada jaringan tiruan kepuasan konsumen (Satisfaction) sebesar 345,828 dengan langkah yang dilalui untuk mencapai model yang mungkin adalah sebanyak 65137 langkah. Model RNN menunjukkan selisih eror yang kecil antara data latih dan data tes, artinya model RNN konsisten dalam memprediksi kepuasan konsumen untuk kedepannya.
