A branch and bound algorithm for the response time variability problem
(Editorial Board, 2012-06-22)
Article
Restricted access - publisher's policyThe response time variability problem (RTVP) is an NP-hard scheduling problem that has been studied intensively recently and has a wide range of real-world applications in mixed-model assembly lines, multithreaded computer ... -
A detailed workforce planning model including non-linear dependence of the capacity on the size of the staff and cash management
(2010-01)
Research report
Open AccessThis paper introduces an original planning model which integrates production, human resources and cash management decisions, taking into account the consequences that decisions in one area may have on other areas and ... -
A framework for designing a supply chain distribution network
(Taylor & Francis, 2018-10-08)
Article
Open AccessBased on the analysis of the pertinent literature, we propose a framework to serve as a guide in designing a distribution network as a component of a supply chain (SC). It consists of three steps that are common to goods ... -
A model for designing a procurement-inventory system as a defence against a recurring epidemic
(2021-05-06)
Article
Open AccessThe COVID-19 pandemic has caused a general shortage of personal protection products and therapeutic devices, which has highlighted the need for each country to have its own production resources and not depend solely on ... -
A multistage graph-based procedure for solving a just-in-time flexible job-shop scheduling problem with machine and time-dependent processing costs
(2018-04-01)
Article
Open AccessThis paper deals with a new flexible job-shop scheduling problem in which the objective function to be minimised is the sum of the earliness and tardiness costs of the jobs and the costs of the operations required to perform ... -
A multistage scenario optimisation procedure to plan annualised working hours under demand uncertainty.
(Elsevier, 2008-06)
Article
Open AccessThe annualisation of working hours (i.e., the irregular distribution of the total number of working hours over the course of a year) makes it possible to adapt production capacity to fluctuations in demand. The required ... -

A remark about "A comment on consecutive-2-out-of-n systems"
(Elsevier, 2002-02)
Article
Open AccessDeǐneko and Woeginger (Oper. Res. Lett. 28 (2001) 169) present a proof that a result of Du and Hwang (Math. Oper. Res. 11 (1986) 187) about the optimum arrangement of the items in a consecutive-2-out-of-n cycle system is ... -
A scenario optimisation procedure to plan annualised working hours under demand uncertainty
(2006-03)
Research report
Open AccessAnnualising 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
(2010-01-01)
Article
Restricted access - publisher's policyWorking 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 ... -
Affectation de véhicules aux routes dans un système de transport multi-école
(Universitat Politècnica de Catalunya. Centre de Càlcul, 1990)
Article
Open AccessEste artículo describe una parte del sistema TRESCA para la organización del transporte escolar en Andorra. Una vez determinadas las rutas a ofrecer, conviene asignarles los vehículos para minimizar los costes. El algoritmo ... -
An exact procedure to plan holidays and working time under annualised hours considering cross-trained workers with different efficiencies
(Taylor & Francis, 2008-04)
Article
Open AccessAnnualising 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
(Operational Research Society, 2005-03)
Article
Open AccessAnnualising 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, ... -

Open AccessEl problema del reparto proporcional ha sido estudiado principalmente en relación con el reparto de escaños en una cámara de representantes, pero tiene muchas otras aplicaciones, una de las cuales es la resolución del ... -
Application of genetic algorithms to assembly sequence planning with limited resources
(IEEE Computer Society Conference Publishing Services (CPS), 1999-07-24)
Part of book or chapter of book
Restricted access - publisher's policyHeuristic procedures based on priority rules are quite frequently used to solve the multiple resource-constrained project-scheduling problem (RCPSP), i.e. task programming with limited resources. The rules are based on the ... -
Assessing the impact on optimal production capacities in a closed-loop logistics system of the assumption that returns are stochastically independent of sales
(School of Industrial and Aeronautic Engineering of Terrassa (ETSEIAT). Universitat Politècnica de Catalunya (UPC), 2011-09)
Article
Open AccessPurpose: This paper is concerned with a reverse logistic system where returns are stochastically dependents on sales. The aim of the paper is to assess the influence on optimal production capacities when is assumed that ... -
