Even though this integration leads to significant benefits to the decision process, it brings several implications that deserve a deep and detailed analysis with regard to some analytical aspects of the mathematical modeling of the method. Integrating the information obtained by these two different protocols causes significant modifications in the space of weights that may have noteworthy impacts on the results. Hence, this paper focuses its efforts on tackling and investigating such aspects of the FITradeoff method. We analyze properties and analytical aspects of FITradeoff in depth, in order to investigate how the information of holistic judgments can be inserted into the mathematical model of FITradeoff and to determine the potential implications of such integration, such as defining preference relationships and identifying potentially optimal alternatives. In addition, a new heuristic to reduce the number of questions in the elicitation by decomposition of FITradeoff is proposed. We also address situations of inconsistencies that may arise due to the conflicting information provided by decomposition and holistic judgments, as well as ways to solve such inconsistencies.","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"16 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140812303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are several variants that include new constraints to the classical problem that make it more realistic. In this work, we study the variant that considers interconnected facilities, that is, the distances between each pair of facilities are less than or equal to a certain threshold <math>\u0000 <semantics>\u0000 <mi>r</mi>\u0000 <annotation>$r$</annotation>\u0000 </semantics></math>. This optimization problem, usually known as the median location problem with interconnected facilities, consists of locating a set of interconnected facilities to minimize the distance between those interconnected facilities and the demand points. The large variety of real-world applications that fit into this model makes it attractive to design an algorithm able to solve the problem efficiently. To this end, a procedure based on the variable neighborhood search methodology is designed and implemented by using problem-dependent neighborhoods. Experimental results show that our proposal is able to reach most of the optimal solutions when they are known. Additionally, it outperforms previous state-of-the-art methods in those instances where the optima are unknown. These results are further confirmed by conducting nonparametrical statistical tests.","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"32 1","pages":"69-89"},"PeriodicalIF":3.1,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/itor.13468","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140666008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the global population has relocated from rural to urban areas. The ecological impact of agriculture is a rising concern. Furthermore, food insecurity, particularly food availability, remains a significant issue. Satisfying rising food demand with minimal environmental impact is a significant barrier to more sustainable food production. In this article, we study a sustainable location for urban farming that optimally balances economic and environmental objectives. We formulate the problem as a multi-objective linear program that considers maximizing the ecological benefit and crop production yield and minimizing transportation cost, sensor cost, and CO2 emissions. The proposed mathematical model is then solved using a two-phase method. The first phase uses several multi-objective optimization (MOO) methods (weighted sum, epsilon-constraint, augmented epsilon) to generate a pool of compromise solutions. The second phase uses multi-criteria decision-making (MCDM) methods (MARCOS, VIKOR, and Possibility Degree) to rank compromise solutions. We performed a sensitivity analysis first by studying the effect of different criteria weights (balanced, environmentally, and economically oriented) and then by investigating the rank reversal. Furthermore, we developed a thorough validity test that examines the impact of the dynamic elements of rank reversal by changing the importance of the model's input parameters. To provide a fusion ranking of the MCDM rankings, we devised an aggregated ranking approach using the half-quadratic (HQ) method.","PeriodicalId":49176,"journal":{"name":"International Transactions in Operational Research","volume":"32 2","pages":"769-801"},"PeriodicalIF":3.1,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/itor.13460","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140600077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
