Purpose: Understanding how the structure affects logistical performance and food security is critical in the supply chains of perishable foods (PFSC). This research proposes a system dynamics model to analyze the effects of structures: lean, agile, flexible, responsive and resilient, in the overall performance and of each agent of the PFSC.Design/methodology/approach: Using a system dynamics model and design of experiments it is studied how the different structures and their combination, affect the behavior of inventory, transportation, responsiveness, efficiency, availability and quality-safety of the fresh fruits supply chain and each echelon.Findings: The studies of supply chains have been done for each structure in an independent way; investigations are scarce in supply chains of perishable foods. The structures modeled in this research do not show the better performance in all the metrics of the chain, neither in all agents for each structure. The above implies the presence of trade-offs.Research limitations/implications: The results show the need to investigate mixed structures with the FPSC´s own characteristics; the model can be applied in other supply chains of perishable foods.Practical implications: Management by combining structures in the FFSC, improves logistics performance and contributes to food security.Social implications: The agents of the FFSC can apply the structures found in this study, to improve their logistics performance and the food security.Originality/value: The dynamics of individual and combined structures were identified, which constitutes a contribution to the discussion in the literature of such problems for FFSC. The model includes six echelons: farmers, wholesalers, agro-industry, third-party logistics operators and retailers. The dynamic contemplates deterioration rate to model perishability and others losses.

This article presents two case studies using system dynamics to analyze the sustainability of military workforce supply chains. The first case is about multi-period force expansion. An analytical expression is presented to relate the expansion target, training capacity, and expansion period. The system dynamics model forecasts the personnel level achievable against the expansion target for varying input of training capacities. This can be used to inform military force planners about the required training capacity and timeframe to achieve the expansion. The second case examines the sustainability of the deployment of a volunteer-based Army reserve unit. The soldiers’ behavior changes due to their deployment experiences (in terms of willingness to deploy) are modeled and their impact on personnel availability is simulated. The second system dynamics model predicts the personnel level sustainability against the required number of soldiers to deploy. It provides insights regarding the required size of the pool of soldiers to support a deployed Army reserve unit, and promotes policy exploration to boost soldiers’ willingness to deploy. In conclusion, this work demonstrates the applicability of system dynamics to assist decision makers in “raising, training, and sustaining” military workforce supply chains.
