Sharing delay costs in stochastic scheduling problems with delays
(Springer, 2020)
[Abstract]: An important problem in project management is determining ways to distribute amongst activities the costs that are incurred when a project is delayed because some activities end later than expected. In this ...
ProjectManagement: an R Package for Managing Projects
(R Foundation for Statistical Computing, 2020)
[Abstract]:Project management is an important body of knowledge and practices that comprises the planning, organisation and control of resources to achieve one or more pre-determined objectives. In this paper, we introduce ...
New results on egalitarian values for games with a priori unions
(Taylor and Francis, 2023)
[Abstract]: Several extensions of the equal division value and the equal surplus division value to the family of games with a priori unions have been proposed by Alonso-Meijide et al. [On egalitarian values for cooperative ...
Necessary players and values
(Springer, 2022)
[Abstract]: In this paper we introduce the Γ value, a new value for cooperative games with transferable utility. We also provide an axiomatic characterization of the Γ value based on a property concerning the so-called ...
Considerations on the programmed functional life (one generation) of a green artificial reef in terms of the sustainability of the modified ecosystem
(Elsevier. Cell Press, 2023-04)
[Abstract] The installation of artificial reefs serves to enhance marine ecosystems, although it also modifies them. These changes do not have to be irreversible, since it is possible to treat the functional life of an ...
On the Reliability of Machine Learning Models for Survival Analysis When Cure Is a Possibility
(MDPI, 2023-10-02)
[Abstract]: In classical survival analysis, it is assumed that all the individuals will experience the event of interest. However, if there is a proportion of subjects who will never experience the event, then a standard ...
Small area estimation of expenditure means and ratios under a unit-level bivariate linear mixed model
(Taylor and Francis Group, 2022)
[Abstract]: Under a unit-level bivariate linear mixed model, this paper introduces small area predictors of expenditure means and ratios, and derives approximations and estimators of the corresponding mean squared errors. ...
Small area prediction of proportions and counts under a spatial Poisson mixed model
(Springer Nature, 2023-10-31)
[Abstract]: This paper introduces an area-level Poisson mixed model with SAR(1) spatially correlated random effects. Small area predictors of proportions and counts are derived from the new model and the corresponding mean ...
A Product-Limit Estimator of the Conditional Survival Function When Cure Status Is Partially Known
(Wiley, 2021-03-01)
[Abstract] We introduce a nonparametric estimator of the conditional survival function in the mixture cure model for right-censored data when cure status is partially known. The estimator is developed for the setting of a ...
An Adaptive Large Neighbourhood Search algorithm for a real-world Home Care Scheduling Problem with time windows and dynamic breaks
(Elsevier Ltd, 2023-11)
[Abstract]: This paper presents a Home Care Scheduling Problem (from now on HCSP) based on a real case of a care company for elderly and dependent people located in the North of Spain. The problem incorporates many of the ...
