The objective is to reduce consumer waiting time costs, FAPs' quality loss costs, and logistics-related costs. We proposed a customized heuristic algorithm to solve the model and determined through numerical testing that the logistics plan with the optimal departure time is better than the fixed departure time logistics plan. Furthermore, comprehensive sensitivity analyses demonstrate that adjusting key cost parameters within feasible thresholds can offset their individual impacts on total cost, thereby maintaining cost stability. Logistics efficiency can only be constantly improved to lower time penalty costs, since it is more difficult to reduce costs connected to customer time satisfaction by coordinating other expenditures.</p></div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"349 3","pages":"1957 - 1984"},"PeriodicalIF":4.5,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145160662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The performance of a transport system will depend heavily on users behavior and decisions. Generally, users have individual objectives, such as seeking to minimize their own travel time. These decisions can affect the performance of the entire system, making it inefficient. A measure that allows to quantify the inefficiency of the system in the face of non-cooperative behavior is the price of anarchy. Our objective is to investigate the price of anarchy in the common-lines problem. In this approach, users choose which lines to use based on the best strategy for them. While Wardrop equilibrium has been studied for the common-lines problem, no contributions have been made toward the social optimum. In this work, we propose two optimization problems to obtain this optimum on simple networks, using strategy flow and line flow formulations. In addition, we prove that both optimization problems are equivalent, and we obtain a characterization of the social optimum flows. These contributions allow us to obtain results about the behavior of the price of anarchy in simple networks as demand increases.</p></div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"349 3","pages":"1785 - 1815"},"PeriodicalIF":4.5,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main aim of this research is to show that introducing temperature as a time-dependent variable in route design offers a more accurate approximation of energy consumption in a refrigerated fleet that is primarily influenced by the internal–external temperature differential. Results show that considering time-dependent temperature variations provides more accurate refrigeration consumption estimates, with differences up to 16% compared to average temperature models. Refrigeration accounts for about 44% of total energy consumption, with product load and infiltration contributing 80% and 17%, respectively.

In each period, decisions are constrained by limits on the releases and the level of the four reservoirs, among others. The approach is a revisit of our previous work on simplicial approximate stochastic dynamic programming, in which the so-called cost-to-go or value functions are approximated over grid points chosen as vertices of simplices. The latter are constructed by first partitioning the reservoir level space into simplices and then iteratively subdividing existing simplices until a desired approximation error or a fixed number of grid points is reached. For each simplex, the approximation error is given by the difference between an upper and a lower bound. This scheme requires storing the list of created simplices in memory. In each iteration, the list is searched to find the existing simplex with the highest approximation error. This may be time-consuming as the number of existing simplices may be very large. In the new proposal, we avoid creating a long list of simplices by combining the original simplicial scheme with Monte Carlo simulation, similar to an exploration strategy in reinforcement learning. We benchmark the new method against its ancestor and an internal software package developed and used by an industrial partner, based on operational metrics and the concept of super-efficiency in data envelopment analysis. The Monte Carlo simplex-based scheme (the new method) outperforms the former method on all metrics considered. In addition, we compare the computational efficiency of both methods for different grid sizes. The average CPU time (over 15 replications) of the Monte Carlo simplicial approach varies between 78% and 98% of that of the simplicial method. As the grid sizes increase above 3,000 points, the simplicial method becomes intractable, in contrast to the Monte Carlo version, which confirms the advantage of the latter. Lastly, to further justify the Monte Carlo simplicial method, we create an artificial system by duplicating each component of the original system. In contrast to the new proposal, under the simplicial approach, the problem is tractable only for relatively modest size grids (up to 1,500 points), for which the average CPU time under the Monte Carlo approach varies between 2% and 5% of that of its simplicial counterpart.</p></div>","PeriodicalId":8215,"journal":{"name":"Annals of Operations Research","volume":"351 1","pages":"333 - 364"},"PeriodicalIF":4.5,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
