The objective was to minimize the total weighted tardiness (TWT) on parallel batch processing machines which have incompatible job families, dynamic job arrivals, and constraints on the sequence-dependent setup time and the qualification-run requirements of advanced process control. Since the problem is NP-hard, an ant colony optimization (ACO) algorithm was used to achieve a satisfactory solution in a reasonable computation time. Extensive simulation experiments had been studied to demonstrate the effectiveness of the proposed method. The simulation results showed that the proposed ACO algorithm is superior to a modified Apparent Tardiness Cost-Batched Apparent Tardiness Cost rule adapted to dynamic job arrivals for minimizing the TWT. More machines or the bigger capacity, better improvement of the TWT is achieved. In addition, more machines, jobs or recipes require longer computation time, while bigger capacity requires less computation time.","PeriodicalId":386046,"journal":{"name":"2009 IEEE International Conference on Automation Science and Engineering","volume":"22 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":"126024677","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}

When the supply base of a manufacturer is dispersed globally, the purchaser must decide what item and quantity to order from each supplier, when to order and where to ship. The scenario considered in this paper assumes that suppliers have limited manufacturing capacity, and that demand over a finite planning horizon at each plant of the manufacturing network is known. A cost-effective procurement strategy for the multiperiod horizon needs to be determined. This work develops an analytical model for strategic supplier selection wherein the capacity constraints of each potential supplier, inbound logistics cost variations between truckload and less-than-truckload, and inventory costs are considered. We present a three-stage analytical approach for the solution: in stage one, we solve a carrier selection problem followed by an associated inventory cost estimation in stage two. Total landed cost based supplier selection model is developed in the final stage.","PeriodicalId":386046,"journal":{"name":"2009 IEEE International Conference on Automation Science and Engineering","volume":"34 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":"125097478","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 concentrate only on the portion of the pipe directly controlled by them or at best by their customers and suppliers. This is a myopic view. Supply chains are in fact complex interacting networks linking industries, economies and other organizations, which in turn interact with the landscape and climate. We should identify and study these interactions in order to understand the complexity of operations, to acquire domain knowledge and expertise for building analytics towards excellence in strategy and execution, and to also mitigate the risks involved. For most manufacturing companies their product quality and performance are dealt with by well established manufacturing processes. Companies are now also assessed by the level of secure services provided before, during and after the sale of sustainable products by meeting social, environmental and economic needs. Customers make comparisons based on Total Cost of Ownership rather than Cost of Acquisition. Furthermore the demographics and hence the consumerism of the world will be changing. According to Goldman Sachs, two billion people may join the global middle class by 2030. These new consumer markets should develop economically in a sustainable way. Hence “green” awareness, compliance and regulations around societal, economic concerns will assume great importance. A tangible product, the services associated with it, and the relationship between the two over time constitute the three dimensions that together fully define a “service product”. We look at this rather complex and important problem and suggest a framework for analysis and design of GIMSN.","PeriodicalId":386046,"journal":{"name":"2009 IEEE International Conference on Automation Science and Engineering","volume":"28 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":"115496344","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 of the principal causes of this high cost is the large amount of “paperworkz” — the administrative expenses incurred for each medical procedure. While the debate continues about whether the country would be better off with a single-payer medical system or the current private insurance approach, there are a number of ways to reduce the administrative costs without excessive risk. These costs are essentially about getting information in the right form, to the right place, at the right time — a challenge that is by no means unique to the healthcare industry. This presentation identifies some of the approaches that have been successful in the manufacturing sector to make the sharing of information — interoperability — more efficient. Manufacturing technology has been developing and improving for decades. Principles like lean manufacturing, paperless design, ISO 9000 performance practices and Taguchi methods are a given for today's major manufacturers. With trends toward global manufacturing and outsourcing, practices have now evolved to Internetbased communication of engineering designs, inventory levels, purchase orders, and a wide variety of other logistical, financial and technical data. Supporting all this, a suite of standards has been developed, deployed, and winnowed down to some that really help, leaving others that seemed promising but failed to meet expectations by the wayside.","PeriodicalId":386046,"journal":{"name":"2009 IEEE International Conference on Automation Science and Engineering","volume":"2 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":"122217797","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}

This paper addresses the problem of the modeling and management of ITS at the operational level considering the impact that the new Information and Communication Technologies (ICT) tools can have on management and control of these systems. An effective ITS model at the operational level should focus on evaluating performance indices describing activities, resources and concurrency, by integrating information and financial flows. To this aim, ITS are regarded as discrete event systems and are modeled in a Petri net framework. We consider as a case study the ferry terminal of Trieste (Italy) that is described and simulated in different operative conditions characterized by different types of ICT solutions and information. The simulation results show that ICT have a huge potential for efficient real time management and operation of ITS, as well as an effective impact on the infrastructures.","PeriodicalId":386046,"journal":{"name":"2009 IEEE International Conference on Automation Science and Engineering","volume":"18 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":"132417752","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}
