The formulation of the JSP is based on the assumption that for each part type or job there is only one process plan that prescribes the sequence of operations and the machine on which each operation has to be performed. Flexible job shop scheduling problem (FJSP) is an extension of the JSP, which allows an operation to be processed by any machine from a given set. Since FJSP requires an additional decision of machine allocation during scheduling, therefore it is much more complex problem than JSP. To solve such NP-hard problems, heuristic approaches are commonly preferred over the traditional mathematical techniques. This paper proposes a particle swarm optimization (PSO) based heuristic for solving the FJSP for minimum makespan time criterion. The performance of the proposed PSO is evaluated by comparing its results with the results obtained using ILOG Solver, a constraint-programming tool. The comparison of the results proves the effectiveness of the proposed PSO for solving FJSP instances.","PeriodicalId":386046,"journal":{"name":"2009 IEEE International Conference on Automation Science and Engineering","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130093419","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}

Appropriate control is typically enabled by the use of micromanipulators; however, manual execution of biomanipulations is difficult, requiring extensive operator training (up to one year) and meticulous work under fatiguing conditions. Automation can be an alternative to improve such operations. In this case, challenges such as interface design, system integration, acquisition of feedback data, and the design of control systems have to be dealt with. This paper concentrates in the later challenge and proposes a new strategy for fast and precise control of the micromanipulation robot. Here, problems related to tool position drift are dealt with using continuous system recalibration. In addition, speed limitations imposed by the vision system are eliminated by the definition of a guaranteed region of interest (gROI) for micropipette localizations. The final system combines the use of mapping functions and visual servoing to achieve a 60% speedup in positioning speed and an 85% reduction in the pipette positioning error. The design and evaluation of this new positioning system is described here, including detail explanations of its modules and their interconnections.","PeriodicalId":386046,"journal":{"name":"2009 IEEE International Conference on Automation Science and Engineering","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125776235","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}

Radio Frequency Identification (RFID) technology has gained prominence as a solution to this approach. However, issues such as presence of metals and frequency interference hamper its performance and value derived out of its implementation in many environments. To analyze the true value of an RFID system we formulate a Partially Observable Markov Decision Process (POMDP) model for RFID directed search to detect misplaced items. A forklift operator (FLO) in a warehouse assigned to locate a misplaced item is guided by the imperfect variations in the strength of the signal received from the RFID tag (active or passive). The POMDP considers five possible FLO actions, five RFID observations in scenarios with different reader-tag signal strength distributions. The results indicate that the POMDP can provide shortest path to locate the tag when RFID signal strength is high . As the signal strength decreases, the signals received (observations) become more dispersed, and the number of steps to reach the tag increases considerably. The expected reward (roughly reduction in search effort) from a 20-step POMDP with high signal strength was 18 times higher than for the low strength (i.e., poor/dispersed observations) model. While even a poorly designed RFID system provides marginal benefits in environments devoid of a sophisticated warehouse management system (WMS), the results show that with the use of WMS (i.e., situations involving strong prior knowledge) adopting a poorly designed RFID system may actually cost the firm more than without it.","PeriodicalId":386046,"journal":{"name":"2009 IEEE International Conference on Automation Science and Engineering","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116626237","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 have developed a CAOS system called OrthoSYS, driven by geometric reasoning algorithms to visualize tumor size, shape, and plan for resection according to the tumor's spread, starting from a 3D model reconstructed from CT images. Anatomical landmarks on bone are automatically identified and labeled, useful for registering patient model with virtual model during surgery and also as a reference for tumor resection and prosthesis positioning. The thickness of bone stock remaining after tumor resection is automatically analyzed to choose the best modular stem and fix the prosthesis. A method for prosthesis components selection using fuzzy logic has been developed to assist the surgeons. The medial axis of the long bones and anatomical landmarks are used for positioning the prosthesis in virtual planning and verification in the intraoperative stage. A set of anatomical metrics have been developed to measure the effectiveness of the prosthetic replacement of bone.","PeriodicalId":386046,"journal":{"name":"2009 IEEE International Conference on Automation Science and Engineering","volume":"186 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113992561","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}
