The main components of SM cloud are designed, and its research topics are summarized. Then, SM's key technologies are studied. 3D technologies for apparel customization, like 3D modeling, 3D fitting mirror and 3D customization, are developed to improve the customization precision and user experience. Information based collaborative management is realized to share, communicate,and handle the information efficiently among all groups and individuals of SM cloud. Suppliers' evaluation mechanism is designed to support the optimal decisions making. Next, SM cloud is constructed in five layers for high-end apparel customization.By using SM cloud based crowd-sourcing, social resources can be allocated rationally and utilized efficiently, consumer can customize the product in any processes like innovation, design,making, marketing and service, and traditional apparel enterprise can be upgraded into SM mode for keeping it competitive in the future customization markets.展开更多

Quality function deployment (QFD) is a widely used management technique for understanding the voice of the customer (VOC), however, QFD depends heavily on human subject judgment during extracting customer requirements and determination of the importance weights of customer requirements. QFD pro-cess and related problems are so complicated that it is not easily used. In this paper, based on a general data structure of product family, generic bill of material (GBOM), association rules analysis was introduced to construct the classification mechanism between customer requirements and product architecture. The new method can map customer requirements to the items of product family architecture respectively, accomplish the mapping process from customer domain to physical domain directly, and decrease mutual process between customer and designer, improve the product design quality, and thus furthest satisfy customer needs. Finally, an example of customer requirements mapping of the elevator cabin was used to illustrate the proposed method.展开更多

Fig.1 Relationships among optimization methods for MCThe methods for MC relate to both of product and process, also customized quanti ty and deepness. The methods for MC are integrated by the work in the paper, whi ch can help to understand and use MC better. The optimization and standardization of product is the key for MC. Increasing op timization breadth in product family can help to decrease the customization quan tity in every section of production process. Increasing optimization deepness in products family can help to move the CODCP backward in production process. At the same time, the optimization and standardization of product is the key to reduce cost of customized product. The optimization of the integration of pr oduct and process is the key to reduce lead time of customized product.展开更多

This is particularly critical when a commercial customized tracheostomy tube cannot be readily obtained. Study Design: Case presentation. Methods/Results: A 73-year-old female was seen in our clinic for management of a recurrent invasive paraganglioma of the thyroid. She underwent a total laryngopharyngectomy, cervical esophagectomy, and anterolateral thigh free flap reconstruction followed by post-operative radiation. In follow-up, the patient presented with dyspnea related to two areas of stenosis, one at the level of her stoma and one at the distal trachea. The patient was therefore taken to the operating room urgently for dilation and placement of a tracheostomy tube. Available tracheostomy tubes were tried and ill fitting as each tube narrowed the patient’s stoma or abutted her distal granulation tissue. To custom create a tracheostomy tube, we used a standard rib shearer to shorten a #6 uncuffed tracheostomy tube by 2 cm. The edges were further smoothed and beveled using sand paper and a diamond burr drill. The finished product was a wide diameter tube with a custom length suited to our patient. Conclusions: Although a simple solution, the use of a rib shearer provides a quick and feasible solution to creating custom length tracheostomy tubes in situations where custom length tubes are needed yet unavailable.展开更多
