The increasing needs for efficient traffic management strategies and for efficient, reliable and safe traffic infrastructures is changing the point of view on mathematical models from bare simulation tools to sophisticated design and optimization tools. Moreover the attention is rapidly moving the focus from centralized supervision strategies, to decentralized control strategies. In this paper we present a modular microscopic mathematical model for heterogeneous vehicular traffic on road networks, able to describe vehicles interactions with the network infrastructure (roads, traffic lights, etc.) and with other vehicles according to the well known potential fields approach. The modeling tool is able to capture different vehicles interactions and traffic phenomena such as queues, overtaking and car crashes. The obtained modeling tool has a strong control-oriented and optimization-oriented characterization and appears promising for traffic supervision and control design and for addressing optimization problems when designing the traffic infrastructure.","PeriodicalId":236208,"journal":{"name":"2011 IEEE International Conference on Automation Science and Engineering","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124101398","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}

They are characterized by long processing times with batching requirements. The problem is further complicated by stringent limitations on waiting times before furnace processing and the heterogeneous tool configuration. A novel integer programming model of allocating furnace tools to process steps over time for achieving production targets is first formulated. The formulation adopts difference equations to describe flows of wafers-in-process (WIPs) and availability of individual tools. Waiting time limitation is captured by an inequality for every time slot that the number of wafers processed in the next time slots within the limitation must be no less than the available WIPs of the current time slot. Constraints on batching decision couple among constraints of wafer flow, tool availability and bounds of batch size. After converting all the constraints to linear forms, an optimization tool suite is then applied to solving test problems derived from a real fab with a stopping criterion of no more than 5% difference from optimality. Comparisons with a currently practiced heuristic show that the near optimal furnace allocations lead to 18.5% more processing in average and 39.6% shorter average waiting time in certain cases than those of the heuristic. Computation times are all within 30 seconds over a personal computer with a Intel P8700@2.53 GHz CPU. Such computation efficiency indicates a strong potential for applications to dynamic allocations in a fab.","PeriodicalId":236208,"journal":{"name":"2011 IEEE International Conference on Automation Science and Engineering","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127867930","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}

It is almost impossible to solve the problem via an analytical study, while experimental studies usually are very costly and time consuming. To overcome these difficulties, this paper proposes a simulation based approach to evaluate and optimize the energy consumption of a manufacturing facility, and we use a typical welding shop as an example. To achieve long term low energy consumption, we face a two-level optimization problem: the building design and daily production scheduling. In the proposed approach, we use EnergyPlus for integrated energy usage estimation and we apply Ordinal Optimization (OO) method and Genetic Algorithms (GA) for optimization of building design and production scheduling, respectively. Numerical examples and results are provided. The optimization concept and the modeling framework could be used for manufacturing facility design and production scheduling to minimize the total energy consumption while maintaining production throughput.","PeriodicalId":236208,"journal":{"name":"2011 IEEE International Conference on Automation Science and Engineering","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131851451","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}
