It is commonly observed that pedestrians behave quite differently when walking in dense crowd. Some people explore routes towards their destinations. Meanwhile, some people deliberately follow others, leading to lane formation. Based on these observations, two roles are included in the proposed model: leader and follower. The motion behaviors of leader and follower are modeled separately. Leaders' behaviors are learned from real crowd motion data using state-action pairs while followers' behaviors are calculated based on specific targets that are obtained dynamically during the simulation. The proposed role-dependent data-driven model is trained on crowd video data in one dataset and is then applied to two other different datasets to test its generality and effectiveness. The simulation results demonstrate that the proposed role-dependent data-driven model is capable of simulating crowd behaviors in crowded scenes realistically and reproducing collective crowd behaviors such as lane formation.","PeriodicalId":325258,"journal":{"name":"Proceedings of the 2016 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132435821","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}

While an interest to evaluate economically effective policies is increasing worldwide, testing hypothesized policies with a real society is highly risky. To overcome this difficulty, we present an agent-based social simulation model based on the low fertility trap hypotheses, which includes human network, social heterogeneity, demographic condition, and economic activity. We aim to 1) analyze the interaction between economic state transitions and demographic events in terms of ageing, low fertility, and economic instability and 2) use the social simulation model to support political decision making based on real case study data from South Korea. An initial designed experiment shows that ageing and low fertility are mutually related to individual economic capability. Low fertility is also found to be a consequence of creating an economic buffer against consumption and well-being of people in a society, especially with a high number of elderly. This current study is the first phase of the hybrid simulation model integrating the statistical-based micro simulation and system dynamics simulation approaches in our on-going work to create the hybrid demographic simulation model using South Korean case study to better understand social phenomena and to provide economic solutions during crises.","PeriodicalId":325258,"journal":{"name":"Proceedings of the 2016 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"44 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127569314","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}

Accurate simulation of dynamically varying behavior of large components in these domains requires the DES engines to be scalable and adaptive in order to complete simulations in a reasonable time. This paper takes a step towards development of such a simulation engine by redesigning ROSS, a parallel DES engine in MPI, in Charm++, a parallel programming framework based on the concept of message-driven migratable objects managed by an adaptive runtime system. In this paper, we first show that the programming model of Charm++ is highly suitable for implementing a PDES engine such as ROSS. Next, the design and implementation of the Charm++ version of ROSS is described and its benefits are discussed. Finally, we demonstrate the performance benefits of the Charm++ version of ROSS over its MPI counterpart on IBM's Blue Gene/Q supercomputers. We obtain up to 40% higher event rate for the PHOLD benchmark on two million processes, and improve the strong-scaling of the dragonfly network model to 524, 288 processes with up to 5x speed up at lower process counts.","PeriodicalId":325258,"journal":{"name":"Proceedings of the 2016 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116837157","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}

Currently, relational databases are often used for this task in simulation applications. In contrast, our approach combines novel wait-free nested hash map techniques with traditional graphs which results in a schema-less, in-memory, highly efficient data management. Our GraphPool stores static and dynamic parts of a simulation model, distributes changes caused by the simulation and logs the simulation run. Even more, the GraphPool supports sophisticated query types of traditional relational databases. As a consequence, our GraphPool overcomes the associated drawbacks of relational database technology for sophisticated 3D simulation applications. Our GraphPool has several advantages compared to other state-of-the-art decentralized methods, such as persistence for simulation state over time, object identification, standardized interfaces for software components as well as a consistent world model for the overall simulation system. We tested our approach in a synthetic benchmark scenario but also in real-world use cases. The results show that it outperforms state-of-the-art relational databases by several orders of magnitude.","PeriodicalId":325258,"journal":{"name":"Proceedings of the 2016 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114954028","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}

Healthcare executives are, and will be, in an inevitable need of evidence-based artifacts for decision making. The paper addresses issues in the context of discharge planning for elderly patients with application to hip fracture care in Ireland. A hybrid approach is embraced that integrates simulation modeling with machine learning in an attempt to improve the validity of the simulation model outputs. In terms of simulation modeling, a discrete event simulation model is used to model the elderly patient's journey through the care scheme of hip fracture. In tandem with the simulation model, predictive models are used to guide the simulation model. Specifically, the predictive models are used to make predictions on the inpatient length of stay and discharge destination of simulation-generated patients. On a population basis, the simulation model provides demand predictions for healthcare resources related to discharge destinations, with a focus on long-stay care such as nursing homes. Our results suggest that there may be a need to reconsider the geographic distribution of nursing homes within particular areas in Ireland in order to keep abreast of the foreseen shift in demographics. Furthermore, the incorporation of machine learning within simulation modeling is claimed to improve the predictive power of the simulation model.","PeriodicalId":325258,"journal":{"name":"Proceedings of the 2016 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134108069","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}

These repetitions are amplified further when a parameter study is conducted where the same model is repeatedly executed with varying parameters, especially when performing multiple runs to increase statistical confidence. Inevitably, such repetitions result in the execution of identical computations, with identical code, identical input, and hence identical output. Performing computations redundantly wastes resources and the execution time of a parameter study could be reduced if the redundancies were avoided. To this end, the idea of memoization was proposed decades ago. However, until today memoization is either performed manually or automated memoization approaches are used that can only handle pure functions. This means that only the function parameters and the return value may be input and output of the function whereas side effects are not allowed. In order to expand the scope of automated memoization to a larger class of programs, we propose an approach able to reliably detect the full input and output of a function, including reading and writing objects through arbitrarily indirect pointers with some preconditions. We show the feasibility of our approach and derive simple performance approximations enabling rough predictions of the expected benefit. By means of a simple case study performing an OFDM network simulation, we demonstrate the practical suitability of our approach, speeding up the execution of the whole parameter study by a factor of 75, while only doubling memory consumption.","PeriodicalId":325258,"journal":{"name":"Proceedings of the 2016 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123762861","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}

By quantitatively profiling the run time characteristics of computer programs, the principal processing needs of commonly used programs became well understood and computer architects can focus their design solutions toward those needs. The DESMetrics project is established to follow this quantitative model by profiling the execution of Discrete Event Simulation (DES) models in order to focus optimization efforts within DES execution frameworks (and especially parallel DES engines). In particular, the DESMetrics project is designed to capture the run time characteristics of event execution in DES models. Because DES models tend to have fine grained computational processing requirements, the DESMetrics project focuses on the event dependencies and their exchange between the objects in the simulation. For now, we assume that optimization of the actual event processing is well served by conventional compiler and architecture solutions. Although, as will become clear later in Section 6, the possibility of identifying scheduling blocks of events that could potentially be schedule together can be achieved - at least within a single simulation object.","PeriodicalId":325258,"journal":{"name":"Proceedings of the 2016 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134199050","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}
