The device under test (DUT) is fixed in the fixture of the motion platform. According to the desired measuring items, the corresponding required measuring probes from different vendors are installed into a probe fetching-fixture by a probe-changing-mechanism. The probe fetching-fixture can rotate in three directions, such as pitch, roll, and yaw. Combining with the digital image guiding device the probes can align and measure the specific point or area of the DUT. In this way the CCMC can measure more than one parameter of the DUT at the same point or perform a variety of measurements with only one floor area of traditional measuring equipment.","PeriodicalId":181408,"journal":{"name":"IEEE International Conference on Automation Science and Engineering, 2005.","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124285070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the nonholonomic chained form and reference model, a nonautonomous system can be obtained and, then, it can be brought to the autonomous form with adequate input signal or feedback controls. Using the Routh-Hurwitz criterion or proper choice of the eigenvalues (of the closed-loop system) it is possible to find conditions that globally stabilize the system. These results are significant to associate linear and geometric control tools with a class of nonlinear systems. It is shown that it is expandable to a n-dimensional two input chained form nonholonomic systems. The simulation of an unicycle control is presented as an application example. Future research include generalization of the method to other forms of nonholonomic systems in R/sup n/ with some uncertainties.","PeriodicalId":181408,"journal":{"name":"IEEE International Conference on Automation Science and Engineering, 2005.","volume":"218 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129802761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this supply network, each retailer faces a random demand of a single product and the supply lead-time from the supplier to distribution centers is random. The problem consists in selecting distribution centers to open in order to minimize inventory and safety stock costs at distribution centers, ordering costs and transportation costs across the network, and fixed facility location costs. The introduction of inventory costs and safety stock costs leads to difficult NP-hard non-linear combinatorial problem. A Lagrangian relaxation approach is proposed to generate efficient solutions and determine tight lower bounds. Numerical results show the efficiency of the proposed method.","PeriodicalId":181408,"journal":{"name":"IEEE International Conference on Automation Science and Engineering, 2005.","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125293485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One kit consists of six or seven components. Production planning in semiconductor testing is complex due to dependant resources requirement and intricate {product, tester, kit, component} qualification relationships. We formulate a multi-period production planning problem employing mixed integer programming (MIP) technique. We consider multiple matching ratios of jointly used testers and kits, allow kit reconfiguration and optimize capacity allocation at the level of kit components. We also conduct weight coefficient analysis to enable multiobjective optimization.

Sensor activation graphs captures, in an intuitive way, the relations between binary sensors, the physical entities that activate them, and the actuators of the system. Models expressed as sensor activation graphs are in most cases significantly simpler than corresponding automata or Petri net models. The presented formalism support two levels of detail, one that gives the general view on the order of sensor activation, and one with full control semantics that incorporates guard conditions on transitions. In addition, an algorithm for converting sensor activation graphs into a number of small deterministic finite state automata is presented.","PeriodicalId":181408,"journal":{"name":"IEEE International Conference on Automation Science and Engineering, 2005.","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130449445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In later 2003, Intel experienced capacity degradation mainly due to the introduction of multiple-chip products (MCP) with re-entrant workflows. We timely re-engineered our factory and generated new methodologies to achieve breakthrough operational excellence. We extended theory of constraints (TOC) to solve the problem of multiple bottlenecks, and developed the dynamic capacity model that captures variability of re-entrant manufacturing systems. Protective capacity (PC) and other parameters at constrained and near-constrained stations are regularly tracked and adjusted to accurately reflect line execution variability in terms of equipment, staff, and WIP. With the implementation and continuous improvement of these methodologies, we increase the factory output by 200% without major capital investment (avoiding millions of capital spending), we maintain 100% volume pass and line item pass for 41 weeks and still counting, and we achieve 30% unit cost cut and brought down subcon price by 26%, which results in over a dozen of millions of dollar cash saving for Intel.","PeriodicalId":181408,"journal":{"name":"IEEE International Conference on Automation Science and Engineering, 2005.","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133452701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We model this strategic decision problem as a mixed integer nonlinear program (MINLP) with the assumption that the good flow is unidirectional, which means the production and distribution networks admit no reverse flow. The proposed model optimizes the overall supply chain costs by taking into account the production cost, the inventory holding cost at the various stages and the transportation cost between the stages.
