Quality procurement is tied with efficient and highly accurate collection of data needed to purchasing the right material at the right quality from right suppliers. Supply chain management (SCM) consists of complex networks of distributed actors in which the problem of identifying the appropriate suppliers based on specific criteria is strategically important. However, implementation of an autonomous assessment that can incorporate dynamics and uncertainty of the whole supply chain during the assessment period is not addressed in most of the previous research activities. In this paper, a review of the use and development of Agent-based Modeling and Simulation (ABMS) approach in the supplier selection problem domain is provided. The main focus of this paper is to extract and analyze significant issues related to modeling and simulating supplier selection networks using Multi Agent System (MAS) approach. Related research domain is evaluated and synthesized considering six different perspectives. The review also sheds light on the weak points of current research in this area. Also, it illuminates a number of key issues which need to be considered in advancing an agent-based assessment model for future applications in supplier selection problem.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124384360","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}

The realization of this task can benefit from a platform assisting the easier task of determining small identifiable parameter subsets. Then, these subsets get enlarged on an iterative basis until a maximal identifiable parameter set is obtained. Moreover, the employment of mutual combinations of many candidates of mathematical tools and algorithmic variants for the underlying interrelated computational subtasks within Parameter Estimation (PE) needs to be examined. This work demonstrates the developer-oriented software DecTrees employed for establishing such a platform. It provides a compact generic implementation of Decision Trees (DTs). The main elements are represented via context-free C++ components describing nodes and conditioned edges. By extending these white-boxes with a context, meaningful applicative decision systems are established. This is the case with the software InteractiveMenus useful for simplifying the configuration of complicated computational tasks. The advantages are emphasized with a realistic IA application.

Awajan","doi":"10.1109/EUROSIM.2013.90","DOIUrl":"https://doi.org/10.1109/EUROSIM.2013.90","url":null,"abstract":"In Amman, the capital city of Jordan, the transportation system is very poor and lacks organization. The only available transportation is busses and taxis. Busses do not follow time schedules and do not have designated bus stops, while taxis are available in large numbers and are more flexible than busses. This results in a high demand on taxis by customers, but unfortunately, there are no taxi parkings, central offices or a booking system for the large number of taxis. Instead taxi drivers orbit the streets of Amman looking for customers randomly and at the same time customers have to walk to main streets to find a taxi. This creates many problems, such as congestion caused by the taxis, increase in oil consumption and time wasting caused by random movement of taxis. This study proposes an automated taxi booking and scheduling system for the taxis available in Amman. The system provides a convenient, assured and safe booking for both taxi drivers and registered customers through mobile devices. The automated taxi booking system was tested and validated under different simulation scenarios. The simulation results show that the automated taxi booking and scheduling system has a clear impact on saving time and oil consumption for taxis.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126118001","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}

With a complex room model which was developed in Dymola-Modelica environment we made several open loop and closed loop experiments using a very efficient combination of Matlab-Simulink and Dymola-Modelica environments. Namely Dymola-Modelica is superior for 'physical modelling'. On the other hand Matlab-Simulink is superior for the design of control schemes but also for more sophisticated analyse and design experimentations: linearization, optimization, control design. The model itself is not described (see references), so the emphasise is given to the experimenting possibilities using the room model. On the bases of open loop analyse of the model simple control algorithms (proportional and proportional-integral) for indoor temperature were developed and tested for the reference and disturbance elimination modes. The results confirm the usefulness of the model and the whole experimental environment as well. Finally both used environments are briefly discussed and some ideas for the future work are given.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121516265","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}

Various methods have been investigated to satisfactorily solve the underlying mathematically, numerically, and computationally challenging partial differential equations. This paper proposes a flexible conceptual framework to formulate and solve the dynamic pantograph-catenary interaction problem by arbitrary approximation onsets and solvers. The proposed framework architecture greatly simplifies the comparison of different solution onsets as it separates physical problem definition, problem approximation and representation, as well as the generic solving task. First, the catenary-pantograph interaction problem is defined in a generic manner. Then, pre-processing steps cast the problem into a finite-dimensional system of ordinary differential equations with algebraic constraints. These are solved in time by suitable solvers and the results are post-processed. This tool chain is demonstrated by comparing selected numeric test results from a Finite Difference and a Fourier approximation onset.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121668764","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 article describes the 3D real time neutronic module, COX-SIMU, developed by EDF engineers and integrated in the simulator by the CORYS T.E.S.S Company. For the calculation of the 3D power distribution, COX-SIMU solves the neutron diffusion equations with 2 energy groups (transient and steady states). A full 3D distribution is needed due to the specifications of the EPRTM reactor internal instrumentation which requires knowledge of the detailed flux distribution for the Protection System. COX-SIMU includes thermal-hydraulical and thermal conduction modules to take into account the water moderator and fuel feedback on neutronic reactions. A simple model based on exponential functions is used for the calculation of the Residual Heat. COX-SIMU is fully validated against the industrial EDF neutronic code COCCINELLE with fine mesh discretization. The modularity and flexibility of COX-SIMU allow its integration in any Pressurized Water Reactor simulators. Thus, COX-SIMU is also integrated in the EPRTM TAISHAN Simulator.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114780558","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}

Algebraic events are an integral part of those models. Their detection in general requires numerical root-finding. This method can be optimized. We show that state-of-the art simulators force unnecessary evaluations during root-finding: The calculation of a residual function is always preceded by the solution of the complete DAE for the active time step. Models are usually composed of hierarchical elements. Therefore, it is quite common, that not the whole DAE needs to be computed for a single event function, although some dependencies exist. By the application of the well known method of causalisation those dependencies can be detected. We show how a subset of the solution algorithm, called a sparse causalisation can be derived from a usual causalisation for a given event variable. When solving the sparse causalisation, the event variable is computed correctly, i.e. it holds the same result as after a complete solution. Depending on the internal structure of the model, the application of sparse causalisation can significantly reduce the amount of work necessary to detect an event.","PeriodicalId":386945,"journal":{"name":"2013 8th EUROSIM Congress on Modelling and Simulation","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124411308","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}
