A scenario optimisation procedure to plan annualised working hours under demand uncertainty
Corominas Subias, Albert; Lusa García, Amaia; Muñoz, Norberto (2006-03)
Report de recerca
Accés obertAnnualising working hours (i.e., the possibility of irregularly distributing the total number of working hours over the course of a year) enables to adapt production capacity to fluctuations in demand. The demand, which ... -
A support tool for working time bargaining by considering individual time accounts and annual leave
Pastor Moreno, Rafael; Corominas Subias, Albert; Olivella Nadal, Jordi (2010-01-01)
Article
Accés restringit per política de l'editorialWorking time accounts (WTAs) are employer-oriented flexibility systems that have been applied in industry but could be used far more. Their use is limited by the complexity of planning them, assessing their financial ... -

An exact procedure to plan holidays and working time under annualised hours considering cross-trained workers with different efficiencies
Lusa García, Amaia; Corominas Subias, Albert; Pastor Moreno, Rafael (Taylor & Francis, 2008-04)
Article
Accés obertAnnualising working hours (AH) is a means of achieving flexibility in the use of human resources to face the seasonal nature of demand. Some existing planning procedures are able to minimise costs due to overtime and ... -
Annualised Hours: A Real Flexibility Tool
Corominas Subias, Albert; Lusa García, Amaia; Pastor Moreno, Rafael (Operational Research Society, 2005-03)
Article
Accés obertAnnualising working hours (AH) is a mean to face the seasonal nature of the demand. AH provides much flexibility to the production system, so the company is allowed to plan the staff working time more efficiently. However, ... -
