Specifically, demand forecasts are often provided by the customers and regularly updated as the related customer information improves. In this paper, we investigate the influence of forecast updates on the production planning method of Material Requirements Planning (MRP). A simulation study was carried out to assess how updates in information affect the setting of planning parameters in a rolling horizon MRP planned production system. An intuitive result is that information updates lead to disturbances in the production orders for the MRP standard, and, therefore, an extension for MRP to mitigate these effects is developed. A large numerical simulation experiment shows that the MRP safety stock exploitation heuristic, that has been developed, leads to significantly improved results as far as inventory and backorder costs are concerned. An interesting result is that the fixed-order-quantity lotsizing policy performs—in most instances—better than the fixed-order-period lotsizing policy, when periodic forecast updates occur. In addition, the simulation study shows that underestimating demand is marginally more costly than overestimating it, based on the comparative analysis of all instances. Furthermore, the results indicate that the MRP safety stock exploitation heuristic can mitigate the negative effects of biased forecasts.</div></div>","PeriodicalId":49518,"journal":{"name":"Simulation Modelling Practice and Theory","volume":"142 ","pages":"Article 103115"},"PeriodicalIF":3.5,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143761236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current research employing social force models typically simulates pedestrian behaviour based on interaction forces under specific visibility conditions. However, these studies often inadequately capture the dynamic effects of visibility changes on pedestrian interaction forces. Based on the nucleus force theory, this study developed an improved social force model (NSFM), incorporating environmental visibility parameters, establishing corresponding pedestrian movement rules. Additionally, we investigated the interaction between pedestrians and walls to determine the optimal parameters. The model’s accuracy was then validated by comparing its simulations under specific visibility conditions from previous visibility-based evacuation experiments and results from other models. Furthermore, we conducted simulations under different visibility conditions, the results show that reduced visibility intensifies wall-following behaviour and herd effects, leading to more detour behaviour, slower movement velocity, and longer evacuation times. As visibility increases, the impact on evacuation gradually diminishes. Finally, we investigated the impact of the number and location of exits and discovered that increasing the number substantially reduces evacuation time, while changes in exit locations can notably affect evacuation efficiency. The numerical simulation results demonstrate that the NSFM has significant potential for simulating pedestrian evacuation behaviour and processes under different visibility conditions, providing a scientific basis for designing more effective evacuation strategies in the future.</div></div>","PeriodicalId":49518,"journal":{"name":"Simulation Modelling Practice and Theory","volume":"142 ","pages":"Article 103117"},"PeriodicalIF":3.5,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenge, the present study proposes a novel Spreadsheet-based Pluviation Parametric Optimizer (SPPO), which is purposely developed for the systematized, controlled, and optimal reconstitution of cohesionless soils. A cohesive integration of a Mechatronic-Assisted Air Pluviation System (MAPS) and the Taguchi-VIKOR-based Multi-response Optimization (TV-MRO) algorithm, devised through SPPO, is utilized to achieve the aforementioned optimal reconstitution. To verify the competence of the decision support framework offered by SPPO, the reconstitution of a poorly graded quartz sand (D<sub>50</sub>=0.22 mm) considering five modelled reconstitution scenarios was conducted. For each modelled reconstitution scenario, SPPO identified an optimal pluviation setting, which was further validated by a confirmatory experiment and a devised optimality criterion. Additionally, it was revealed that the height of fall is the most influential parameter in optimal reconstitution, followed by diffuser ratio and sieve porosity. Overall, it is anticipated that the adoption of SPPO can be effective in reconstituting cohesionless soils with much less reconstitution effort, time, and resource deployment compared to conventional reconstitution methodologies.</div></div>","PeriodicalId":49518,"journal":{"name":"Simulation Modelling Practice and Theory","volume":"142 ","pages":"Article 103116"},"PeriodicalIF":3.5,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments involved individual and group navigation in angled corridor with widths of 1.5, 2.0, 2.5, and 3.0 m, with participants departing from various positions. Data from individual navigation in a 2.0 m corridor were used for model development, while data from other widths and group navigation validated the model. The TSFM represents pedestrians as spherocylinders, where movement is driven by force components and turning by torque components. Unlike traditional models with fixed turning axes and constant angular speeds, the TSFM integrates spatially variable turning start and end positions, angular speed and speed profiles, and turning axis distributions into its forces and torque calculations. Validation results show the TSFM significantly outperforms classic social force models (SFMs). It reduces the trajectory mean squared error from 0.45 m<sup>2</sup> to 0.03 m<sup>2</sup>, and decreases travel time errors from >15 % to <5 %.
