Branzei, R., Gutiérrez, E., Llorca, N., Sánchez-Soriano, J. (2021) «Does it make sense to analyse a two-sided market as a multi-choice game?», Annals of Operations Research, 301 (1-2):17–40

Rodica M. Brǎnzei (Alexandru Ioan Cuza University, Iasi, Romania), Elisabeth Gutiérrez, Natividad Llorca and Joaquín Sánchez (Operations Research Center, University Miguel Hernández of Elche) 
Abstract: In this paper, we introduce the model of multi-choice two-sided market games related to two-sided market situations. Associated with them we study whether the disaggregate management of the individual units of […]

Estañ, T., Llorca, N., Martínez, R., Sánchez-Soriano, J. (2021) «On how to allocate the fixed cost of transport systems», Annals of Operations Research, 301(1-2):81-105

Teresa Estañ, Natividad Llorca, Joaquín Sánchez (Operations Research Center, University Miguel Hernández of Elche) and Ricardo Martínez (Departamento de Teoría e Historia Económica, Universidad de Granada)
Abstract: In this study, we consider different cities located along a tram line. Each city may have one or several stations and information is available about the flow of passengers […]

Sanchez-Soriano, J. (2021) «Families of sequential priority rules and random arrival rules with withdrawal limits», Mathematical Social Sciences, 113:136–148

Joaquín Sánchez (Operations Research Center, University Miguel Hernández of Elche) 
Abstract: This paper deals with extensions of the family of sequential priority rules and the random arrival rule for bankruptcy problems when withdrawal limits are fixed by an arbitrator. We assume two approaches to limit withdrawals. The first is based on the principle that agents can […]

Estañ, T., Llorca, N., Martínez, R., Sánchez-Soriano, J. (2021) «On the Difficulty of Budget Allocation in Claims Problems with Indivisible Items and Prices», Group Decision and Negotiation, 30 (5):1133–1159

Teresa Estañ, Natividad Llorca, Joaquín Sánchez (Operations Research Center, University Miguel Hernández of Elche) and Ricardo Martínez (Departmento de Teoría e Historia Económica, Universidad de Granada)
Abstract: In this paper we study the class of claims problems where the amount to be divided is perfectly divisible and claims are made on indivisible units of several items. […]

Martínez, R., Sánchez-Soriano, J. (2021) «Mathematical indices for the influence of risk factors on the lethality of a disease», Journal of Mathematical Biology, 83 (6-7):74

Ricardo Martínez (Departmento de Teoría e Historia Económica, Universidad de Granada) and Joaquín Sánchez (Operations Research Center, University Miguel Hernández of Elche)
Abstract: We develop a theoretical model to measure the relative relevance of different pathologies of the lethality of a disease in society. This approach allows a ranking of diseases to be determined, which can […]

Acosta, R.K., Algaba, E., Sánchez-Soriano, J. (2021) "Multi-issue bankruptcy problems with crossed claims", Annals of Operations Research,

Rick Kevin Acosta, Joaquín Sánchez (R.I. Center of Operations Research (CIO), Miguel Hernández University of Elche) and Encarnación Algaba (Department of Applied Mathematics II and IMUS, University of Seville)
Abstract: In this paper, we introduce a novel model of multi-issue bankruptcy problem inspired from a real problem of abatement of emissions of different pollutants in which […]

Sainz-Pardo, J.L., Valero, J. (2021) «COVID-19 and other viruses: Holding back its spreading by massive testing», Expert Systems with Applications, 186:115710

José Luis Sainz-Pardo and José Valero (Operations Research Center, University Miguel Hernández of Elche)
Abstract: The experience of Singapore and South Korea makes it clear that under certain circumstances massive testing is an effective way for containing the advance of the COVID-19. In this paper, we propose a modified SEIR model which takes into account tracing […]

Sainz-Pardo, J.L. (2021) «Linear regression strategy for differential evolution», GECCO 2021 Companion – Proceedings of the 2021 Genetic and Evolutionary Computation Conference Companion, 19–20

José Luis Sainz-Pardo (Operations Research Center, University Miguel Hernández of Elche)
Abstract: A new Differential Evolution algorithm is proposed which incorporates a linear regression strategy to find the best single-objective optimization solution. Furthermore, this algorithm contemplates directional information and classical chromosome conservation strategies. Its main motivation is to be used in problems in which it is […]

Ruiz, J.L., Sirvent, I. (2021) «Searching for alternatives to the closest targets: Identifying new directions for improvement while controlling additional efforts», Journal of the Operational Research Society, 72 (12):2770–2782

José Luis Ruiz and Inmaculada Sirvent (Operations Research Center, University Miguel Hernández of Elche)
Abstract: Setting the closest targets is an appropriate approach for planning. Closest targets minimize the gap between actual performances and best practices, so they are the ones that require the least effort from organizations for their achievement. However, this paper shows that, […]
