Multi-agent systems can aid such companies in understanding the different behaviours presented within the context of a society constituted by autonomous entities. We propose a multi-agent simulator capable of emulating different profiles of consumers and equipment. Our approach differs from others in three fundamental aspects: i). it models parameters that are difficult to predict, which are calibrated using values provided by available records; ii). it can be applied to different simulation environments involving various degrees of scalability and heterogeneity of profiles both of individual behaviour and household appliances; iii). it simulates the complexity of the system, providing estimates through the simulation of the interaction between users and electrical appliances. The results obtained by the model were similar to the numbers provided by the literature, which suggests the validity of the proposed approach.","PeriodicalId":51296,"journal":{"name":"Journal of Simulation","volume":"17 1","pages":"17 - 31"},"PeriodicalIF":2.5,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17477778.2021.1931499","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41378975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, one of the significant long-term challenges is sustainability performance across its entire supply chain. However, this is not an easy task given the complexity involved, so decision support tools are fundamental instruments in understanding the entire supply chain from a sustainability performance perspective. Using simulation as a research method, this article proposes a hybrid and hierarchical performance assessment model, considering key sustainability indicators. The model is hybrid due to the use of different simulation methods– System Dynamics (SD), Discrete Event Simulation (DES), and Agent-based simulation (ABS). The model is applied to an aerospace manufacturer’s real case to assess the sustainability performance of alternative SC. Unlike existing contributions, this work addresses the make-to-order supply chain from a sustainability performance perspective and does not compromise the representation of the diverse manufacturing functions and resources.","PeriodicalId":51296,"journal":{"name":"Journal of Simulation","volume":"17 1","pages":"32 - 57"},"PeriodicalIF":2.5,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17477778.2021.1931500","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43522534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, an optimized injection-withdrawal schedule proposed using a simulation-optimization approach enriched with Iterated Local Search heuristic method.

In particular, multimedia traffic – composed of audio, video, and images – represents a challenging scenario requiring link optimisation techniques. The hub-and-spoke topology is frequently used to design more effective telecommunication networks. This work considers a hub-and-spoke network in which a large number of nodes are exchanging real-time multimedia data, and where the quantity of data sent from one node to another is a random variable. Given a fixed number of hubs, , the goal is to select the best location for these hubs in order to minimise the total expected cost of transmission. This scenario is modelled as an uncapacitated single-allocation -hub median problem under uncertainty conditions. Additionally, with the purpose of considering the effect of transmission delays on the video signal, service quality thresholds are assigned to every potential hub in the network. Since real-life networks tend to be large in size, we propose a simheuristic algorithm to cope with this stochastic and large-scale optimisation problem. A series of computational experiments illustrate these concepts and allow for testing the performance of our simheuristic approach. Finally, a statistical analysis of the obtained results is provided.","PeriodicalId":51296,"journal":{"name":"Journal of Simulation","volume":"16 1","pages":"480 - 493"},"PeriodicalIF":2.5,"publicationDate":"2021-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17477778.2020.1863754","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41327178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a solution for the analysed trade-off between a required quick provision of simulation results and a tolerable inaccuracy of the simulation results, the authors describe and evaluate the application of mesoscopic discrete-rate-based simulation models for two typical production and logistics planning tasks in the automotive industry. In terms of level of detail, mesoscopic simulation models fall between object-based discrete-event simulation models and flow-based continuous simulation models. Mesoscopic models mainly represent logistics flow processes on an aggregated level through piecewise-constant flow rates by applying the discrete-rate simulation paradigm instead of modelling individual flow objects. This leads to fast model building and computation.","PeriodicalId":51296,"journal":{"name":"Journal of Simulation","volume":"16 1","pages":"448 - 457"},"PeriodicalIF":2.5,"publicationDate":"2020-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17477778.2020.1841575","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47249891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this analogy, cells are considered as agents (e.g., companies or individual innovators) which are interacting with each other through a competitive interaction network; cancer represents the innovation and the creativity-innovation process is considered to be analogous to the necessary mutations needed within a cell to reach the cancerous state. In this process, agents move from doing business as usual to being creative and then finally innovative. The results show that in an industry with less frequent innovations, innovation emerges faster in structures with local connections. By moving towards more frequent innovations, structures with global and random connections show to be more effective. The outputs provide insights for policy-makers to assess different strategies to facilitate innovativeness for different types of industries. The model also provides a basis to further study the creativity-innovation process.","PeriodicalId":51296,"journal":{"name":"Journal of Simulation","volume":"16 1","pages":"437 - 447"},"PeriodicalIF":2.5,"publicationDate":"2020-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17477778.2020.1832869","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43714673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
