Balancing Systematic and Flexible Exploration of Networks
Social network analysis (SNA) has emerged as a powerful method for understanding the importance of relationships in networks. However, interactive exploration of networks is currently challenging because: (1) it is difficult to find patterns and comprehend the structure of networks with many nodes and links, and (2) current systems are often a medley of statistical methods and overwhelming visu...
متن کاملDynamic Load Balancing with Flexible Workers
We study the problem of dynamically allocating flexible workers to stations in tandem or serial manufacturing systems. Workers are trained to do a subset of consecutive tasks. We show that the optimal policy is often LBFS (last buffer first-served) or FBFS (first buffer first-served). These results generalize earlier results on the optimality of the pickand-run, expedite, and bucket brigade-typ...
متن کاملMass customization of shoes by automatically finding best-fitting shoes
How to meet the technological challenges of designing customized products? Typical customer products, such as shoes, seem to have a simple product structure and a quite low level of complexity. At least if one considers products, such as cars or airplanes. Modern truck factories customize and manufacture trucks, just in time and without being one truck similar to the other. How about shoes? Sho...
متن کاملCorrective shoes and inserts as treatment for flexible flatfoot in infants and children.
We performed a prospective study to determine whether flexible flatfoot in children can be influenced by treatment. One hundred and twenty-nine children who had been referred by pediatricians, and for whom the radiographic findings met the criteria for flatfoot, were randomly assigned to one of four groups: Group I, controls; Group II, treatment with corrective orthopaedic shoes; Group III, tre...
متن کاملA Line-Balancing Strategy for Designing Flexible Assembly Systems
We present a rough-cut analysis tool that quickly determines a few potential cost-effective designs at the initial design stage of flexible assembly systems (FASs) prior to a detailed analysis such as simulation. It uses quantitative methods for selecting and configuring the components of an FAS suitable for medium to high volumes of several similar products. The system is organized as a series...
