Taking decisions on assignment of tasks with path dependent learning curves
(2008-10)
Report de recerca
Accés obertPerformance in doing a task in the learning stage depends on the previous practice on other tasks –learning curve is path dependent. A mathematical program aimed to assign a set of tasks to a set of workers considering ... -
Technical note: relating to the parameter values given by Nelder and Mead in their algorithm
(Wiley Heyden, 2015-01-01)
Article
Accés obertThe popular Nelder and Mead (NM) algorithm has four parameters associated to the operations known as reflection, expansion, contraction and shrinkage. The authors set their values to 1, 2, 0.5 and 0.5, respectively, which ... -

Using a MILP model to establish a framework for an annualised hours agreement
(Elsevier, 2007-03)
Article
Accés obertProduction flexibility is essential for industrial companies that have to deal with seasonal demand. Human resources are one of the main sources of flexibility. Annualising working hours (i.e., the possibility of irregularly ... -
Using discrete-time mathematical programming to optimise the extraction rate of a durable non-renewabre resource with a single primary supplier
(Elsevier, 2017-09)
Article
Accés obertA non-linear discrete-time mathematical program model is proposed to determining the optimal extrac- tion policy for a single primary supplier of a durable non-renewable resource, such as gemstones or some metals. Karush, ... -
Using MILP to plan holidays and working hours under an annualised hours agreement
(2006-04-04T12:46:07Z)
Report de recerca
Accés obertAnnualising work hours (AH) is a means of achievement flexibility in the use of human resources to face the seasonal nature of demand. In Corominas et al. (1) two MILP models are used to solve the problem of planning staff ... -
Using optimal control to optimize the extraction rate of a durable non-renewable resource with a monopolistic primary supplier
(American Institute of Mathematical Sciences, 2022-01-01)
Article
Accés obertThe problem dealt with in this paper is that of optimizing the path of the extraction rate (and, consequently, the price) for the monopolistic owner of the primary sources of a totally or partially durable non-renewable ... -
