In general, it describes how multiple jobs or workloads are processed within a limited set of resources to achieve certain manufacturing objectives, such as minimizing the makespan or weighted tardiness. Nevertheless, as the demand for customized and versatile products increased, these systems became more flexible by incorporating flexible manufacturing processes. As a result, it is possible to vary either the machine operations or the product route within highly automated and connected material handling systems. Therefore, the scheduling process is more complex as it involves solving the routing problem within different alternatives and sharing redundant resources between multiple production processes, thereby increasing workload and bottlenecks within the system. Thus, it is imperative to address the scheduling problem while taking into account the physical constraints caused by shared machines and product routing. This paper proposes a Mixed Integer Linear Programming algorithm to solve the flow-shop scheduling problem and minimize the makespan while balancing the machine usage to limit emergent behaviours due to over-utilization. The robustness of the approach is then verified in the case of delays which alter the processing time on machines. Experiments on a limited instance of a flexible manufacturing system confirm the effectiveness of the solution, with a small increase in completion time even for high-magnitude delays.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125828528","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}

Sometimes, the outcomes that are undesired by decision makers (DMs) or third parties may be obtained. The inverse graph model for conflict resolution (GMCR) is presented to help the DMs or third parties reach to an expected equilibrium. However, in some complex conflicts, different DMs would have distinct behavioral patterns (named combinatorial behaviors), which is beyond the existing inverse GMCR studies. This paper aims to extend inverse GMCR to achieve the desired equilibrium under combinatorial behavior by optimizing the preferences. The combinatorial behavior is first introduced, and then combinatorial equilibrium is formally defined. After that, an inverse preference optimization model with two DMs under combinatorial behavior is developed that is solved by the genetic algorithm (GA). Finally, the Iran nuclear dispute is applied to explain how the proposed approach can be employed in practice.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130543915","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}

Therefore, universities must integrate the development of Digital Twins into their educational program to enable future engineers to overcome the challenges concomitant with Digital Twins. While a theoretical basis for Digital Twins is crucial e.g., hardware-software integration, Internet of Things (IoT) or simulation models, a practical combination of these heterogeneous components is also necessary to introduce the Digital Twin as a whole concept. With Model-Based Systems Engineering (MBSE) an approach was introduced to grasp complexity by using system models e.g., through SysML diagrams. Digital Twins are an example for advanced systems shaped by high complexity. The usage of system models is therefore likely. With this contribution, a concept is presented to combine system models and Digital Twins to create a prototype for academic education and the conduction of student projects.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114069731","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}

Hershey","doi":"10.1109/SoSE59841.2023.10178551","DOIUrl":"https://doi.org/10.1109/SoSE59841.2023.10178551","url":null,"abstract":"This paper focuses on effectively communicating within distributed and disaggregated multi-domain battlespace operational system of systems (SoS) environments. To do so, the individual participating communications systems must be adaptive in response to ever-changing on-mission events such as, network congestion (e.g., degraded comms links and excessive network traffic), enemy interference (e.g., jamming, cyber-attacks), line of sight degradation (e.g., weather conditions). These challenges cause traditional communications systems networks to drop packets, which they presently do according to pre-specified Quality of Service (QoS) policies. However, these QoS policies alone do not actually mitigate the congestion problem because the impacted streams employ reliable communications protocols, such as TCP, that require dropped packets to be retransmitted over the same route. This approach can make the congestion problem even worse and waste the valuable bandwidth. The approach presented here introduces the novel System of Systems (SoS) for Distributed Disaggregated Communications via Reinforcement Learning (RL) and Backpressure (D2CRaB) to overcome the above stated limitations. D2CRaB does so in two ways: (1) by bridging route selection and congestion control via a new backpressure scheme and (2) by leveraging RL to enable the dynamic and continuous adaptation to changing network conditions. These new advancements, greatly extend the available bandwidth of the original congested communications system to that available of other communications systems within the multi-domain SoS. By so doing, congestion can be relieved, and packet drops can be greatly reduced.","PeriodicalId":181642,"journal":{"name":"2023 18th Annual System of Systems Engineering Conference (SoSe)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115013389","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}
