A community electrification project: combination of microgrids and household systems fed by wind, PV or micro-hydro energies according to micro-scale resource evaluation and social constraints
(2014-12)
Article
Open AccessWhen electrifying isolated rural communities, usually standardized solutions have been implemented using the same technology at all the points. However these solutions are not always appropriate to the community and its ... -
A heuristic method to design autonomous village electrification projects with renewable energies
(2014-08-14)
Article
Restricted access - publisher's policySystems relying on renewable energies demonstrated to be a reliable and sustainable option to electrify isolated communities autonomously. Hybrid systems that combine different energy resources and distribution microgrids ... -
A meta-heuristic method to design off-grid community electrification projects with renewable energies
(2015)
Article
Open AccessThe design of off-grid electrification projects considering hybrid systems and distribution microgrids is a complex task that requires the use of decision support tools. Most of existing tools focus on the design of hybrid ... -
A MILP model to design hybrid wind-photovoltaic isolated rural electrification projects in developing countries
(Elsevier, 2013-04-16)
Article
Restricted access - publisher's policyElectrification systems based on the use of renewable energy sources are a suitable option for providing electricity to isolated communities autonomously. Wind and hybrid wind–photovoltaic (PV) systems are increasingly ... -
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 novel algorithm for isolated electrification projects
(2015-05-04)
External research report
Open AccessIn this report it is proposed a metaheuristic procedure to support the design of stand - alone commun ity electrification projects. In particular, the solution returned by the procedure ... -

A step-by-step guide to assist logistics managers in defining efficient re-shelving solutions for retail store deliveries
(2018-01-01)
Article
Open AccessPurpose City logistics is a challenge in many cities. Literature works focus on the analysis of large or local-scale solutions to increase the efficiency of freight transport. However, store deliveries from the perspective ... -
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 ... -
A survey of the parallel assembly lines balancing problem
(2020-12)
Article
Restricted access - publisher's policyAssembly lines are mass production systems which are significant in the industrial production of both standard and customised products. Currently, industrial companies offer several products and it is common for an assembly ... -
Ad-hoc heuristic for design of wind-photovoltaic electrification systems, including management constraints
(2020-12)
Article
Restricted access - publisher's policyIsolated electrification systems based on renewable energy are a suitable option for providing many rural communities in developing countries with access to electricity. In particular, the design of wind-photovoltaic systems ... -
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 ... -
Analysis of urban freight distribution measures
(2015-10-29)
External research report
Open AccessUrban Freight Distribution (UFD) represents a very important activity in terms of cities economy, but can also be a problem for the daily life of citizens, due to traffic, noise and environmental contamination. ... -
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, ... -
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 ... -
