“…Recently, Mustajib and Irianto [10] propossed an integrated model for tolerance allocation and selection process in multi-stage processes. Meanwhile, the importance of determining tolerances for multiple quality characteristics products has been demonstrated by Lee and Tang [11], Chou and Chen [12], Huang et al [13], and Peng et al [14]. Furthermore, many researches [15][16][17] extended this work on assembly products with multiple quality characteristics based on statistical approach.…”

The existences of variances that are very difficult to be removed from manufacturing processes provide significance of tolerance to the product quality characteristics target of customer functional requirement. Furthermore, quality loss incurred due to deviation of quality characteristics of the target with a specified tolerance. This article discusses the development of concurrent engineering optimization model of tolerance design and manufacturing process selection on product with multiple quality characteristics by minimizing total costs in the system, namely total manufacturing cost and quality loss cost as functions of tolerance, also rework and scrap costs. The considered multiple quality characteristics have interrelated tolerance chain. The formulation of proposed model is using mixed integer non linear programming as the method of solution finding. In order to validate of the model, this study presents a numerical example. It was found that optimal solution are achieved from proposed model in the numerical example. Abstrak Rekayasa Simultan Sintesis Toleransi dan Pemilihan Proses untuk Produk dengan Multi-karakteristik Kualitas yang Mempertimbangkan Kapabilitas Proses.Keberadaan variansi yang sangat sulit untuk dihilangkan dalam proses manufaktur memberikan peran penting adanya toleransi terhadap target karakteristik kualitas produk yang menjadi kebutuhan fungsional bagi konsumen. Selanjutnya timbul kerugian kualitas yang disebabkan oleh penyimpangan karakteristik kualitas dari target dengan toleransi yang ditetapkan. Makalah ini membahas pengembangan model optimisasi rekayasa simultan desain toleransi dan pemilihan proses manufaktur pada produk dengan multi karakteristik kualitas untuk meminimasi total ongkos dalam sistem, yaitu total ongkos manufaktur dan ongkos kerugian kualitas yang merupakan fungsi dari toleransi serta ongkos rework dan ongkos scrap. Karakteristik kualitas produk yang diperhatikan dalam penelitian ini memiliki rantai toleransi yang saling berkaitan (interrelated chain). Formulasi model yang dikembangkan menggunakan mixed integer non linear programming sebagai metode pencarian solusi.

“…Under stable fabrication conditions, the processed dimensions often vary within certain controlled ranges. Tolerances are specified to control the actual dimensions of processed features within allowable variation zones for product functional requirements and manufacturing costs (Zhang, 1996;Ngoi and Teck, 1997;Lee and Tang, 2000;Fang and Wu, 2000;Huang et al, 2001;Huang and Gao, 2003;Chen et al, 2003). The contemporary practice of tolerance design has two sequential phases: Product tolerance design and process tolerance design (Ngoi and Teck, 1997).…”

“…Using this method, the research work has been carried out in product design and component process planning stages, respectively. Lee and Tang (Lee and Tang, 2000) presented an optimization model for controlling dimensional tolerances of components with multiple functional characteristics by minimizing the sum of manufacturing cost and quality loss. Jeang (1998) introduced a mathematical optimization model to integrate manufacturing cost and quality loss for tolerance charting balancing during machining process planning.…”

Design and development of high quality products are of utmost importance to any production plant. Product design consists of parameter design and tolerance design, which affect the product performances and the manufacturing costs, respectively. Most products involve more than one quality feature. Design and development of such products raise multi-response surface problems in which it is necessary to determine the optimal values of parameters and the tolerances for all responses simultaneously. In this research, an approach for simultaneous robust parameter and tolerance design is proposed to deal with multi-response problems. The proposed method employs quality loss concept and one-way multivariate analysis of variance. Two simulation studies are performed to validate the applicability of the proposed method. Research findings show that the proposed method performs better in quality improvement as well as in cost reduction than the existing methods. The variances of the responses are also lower than those of the other methods, that is, the proposed method results in a more robust approach to product design.
