RutaRep: a computer package to design dispatching routes in the meat industry
2005
In this paper we present a computer program that has been developed to design the dispatching routes of a medium-sized meat company in Spain. We have modelled the real problem as a variant of the vehicle routing problem with Time Windows and implemented a number of heuristic algorithms based on the most advanced solution techniques for this problem. These algorithms have been embedded in a computer package that is intended to be used as a decision support system for the distribution manager. The program runs under Windows System and is straightforward to use. We also present some computational experiences based on real instances provided by the company. This experience shows important impro…
Tuning Decision Support Toolsfor Environmentally Friendly Manufacturing Approach Selection
2017
Awareness about the environmental performance of manufacturing approaches has arisen. Comparative analyses of different manufacturing approaches as well as decision support methods should be developed in the field of metal shaping processes. The present paper aims at tuning a decision support tool for identifying when mass conserving approaches (forming based) are actually preferable over machining processes for manufacturing aluminum based components. A full LCA is developed for comparing the environmental performance of forming and machining approaches as the batch size and geometry complexity hang. The impact of the used metric on the comparative results is analyzed. Results reveal that …
Improving OHS activities at company level with decision support software
2012
Abstract The paper presents the results of a project implemented at S.C. COMPA S.A., an automotive manufacturing company from Sibiu, Romania. The goal of the project was to develop a practical and sustainable solution for improving the work conditions in the company, by a proactive and systematic evaluation of compliance with national and European OHS legislation. To reach this objective an evaluation methodology was developed and a software system was implemented to support the decisions made by the company and OHS managers to improve work conditions and to grow safety level for the employees. The workplaces problems regarding risks assessment and control are revealed and managers can take…
A Graphical User Interface as a DSS Tool for GHG Emission Estimation from Water Resource Recovery Facilities
2017
A Grafical User Interface (GUI) for the greenhouse gas (GHG) emissions from WWTPs based on four models aimed at quantifying the gas emissions from the aerated tanks (i.e. CAS and MBR reactor), aerobic digesters, secondary clarifiers and anaerobic digesters have been englobed in a GUI in order to provide a valid decision support system (DSS) to the practitioners. The GUI allows to estimate such emissions for the different WWTP phases considered. The GUI has been developed on MATLAB platform and provides as output the GHG emissions in terms of CO2 and N2O fluxes.
Simulation Modeling Using Agents For Mass Customization
2004
Reconfigurable enterprises and production networks — virtual structures of manufacturing enterprises that coalesce and vanish in response to a dynamic marketplace — are one of the main enabler paradigm for mass customizable production. The design and coordination of production networks to changing market dynamics are challenging tasks. Simulation provides the ability to develop prototypes of such complex systems cost effectively and in shorter duration. This Chapter describes how simulation can be utilized in conjunction with multi agent system techniques to develop realistic prototypes of complex decision support systems for the design of coordination strategies in large-scale mass customi…
Workflow-Based Decision Support for Failure Mode and Effects Analysis
2010
Abstract To achieve high quality designs, processes, and services that meet or exceed industry standards, it is crucial to identify all potential failures throughout a system and work to minimize or prevent their occurrence or effects. This paper presents an innovative approach to Failure Mode and Effects Analysis (FMEA) that uses a Decision Support System (DSS) for supporting the FMEA processes. The DSS is powered by a workflow engine that guides the users through the processes by considering standard work templates or previous similar cases. It is also built as a framework for decision support tools so, beside its default one, different FMEA work instruments can be plugged-in and used thr…
Risk Accelerators in Disasters
2014
Published version of a chapter in the book: Advanced Information Systems Engineering. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-319-07881-6_2 Modern societies are increasingly threatened by disasters that require rapid response through ad-hoc collaboration among a variety of actors and organizations. The complexity within and across today's societal, economic and environmental systems defies accurate predictions and assessments of damages, humanitarian needs, and the impact of aid. Yet, decision-makers need to plan, manage and execute aid response under conditions of high uncertainty while being prepared for further disruptions and failures. This paper argues tha…
Including the environmental criteria when selecting a wastewater treatment plant
2014
Abstract Life Cycle Assessment (LCA) is a methodology to generate environmental impact estimates associated with the life cycle stages of a product or process. The approach facilitates a more comprehensive outlook of the end-of-pipe process impacts, in which wastewater treatment plants (WWTPs) are included. Here we describe the implementation of the LCA methodology within a knowledge-based Decision support system (DSS) in order to include the environmental criteria to the decision making process when selecting the most appropriate process flow diagrams for specific scenarios. A sample group of 22 actual operating facilities in Spain, corresponding to five different typologies were assessed …
A multi-agent system for managing adverse weather situations on the road network
2010
The development of traffic management and control strategies to improve traffic flows and road safety is necessary due to the high dynamism of traffic flows. The use of distributed intelligent systems can help the traffic organizations and the road operators to cope with possible incidents on the road network, especially when the incidents are related to adverse meteorological conditions. In that case, the probability of road accidents is increased due to the difficulty of driving under bad weather conditions. So, if the operators detect any meteorological incident, they must decide how to deal with it in order to improve traffic safety. In this paper we introduce a new multiagent system (M…
Assessment of the technical and economic potential of offshore wind energy via a GIS application: A case study for the Sicily Region according to Ita…
2015
This paper presents a technical and economic analysis of the possible exploitation of offshore wind resources using spatial analysis methods based on GIS tools. The study assessed the magnitude and distribution of the main constraints on installation of wind farms by taking into account the relevant technical factors and local laws on nature protection issues in a specific area, i.e., Sicily. Specific cost functions were defined for several components of the total cost of construction and maintenance of a wind farm. Several scenarios were implemented according to wind turbine size, hub height, total wind farm power, and distance from the coast, and the levelised production cost was assessed…
