Decision Support Systems for Truck Route Modelling (D-TRM)
No full textSince the 1970‟s Decision Support Systems (DSS) have become popular following the development in computer technology. A DSS aims to support in the solving of specific problems with both human and computer techniques. The purpose of this research was to design and develop a DSS for application involved with the cost calculations and revenue calculations of contracted timber haulage in Ireland
Decision Support Systems: Advances In
No full textThis book helps the reader understand the power of informed decision making by covering a broad range of DSS (Decision Support Systems) applications in the fields of medical, environmental, transport and business. The expertise of the chapter writers spans an equally extensive spectrum of researchers from around the globe including universities in Canada, Mexico, Brazil and the United States, to institutes and universities in Italy, Germany, Poland, France, United Kingdom, Romania, Turkey and Ireland to as far east as Malaysia and Singapore and as far north as Finland. Decision Support Systems are not a new technology but they have evolved and developed with the ever demanding necessity to analyse a large number of options for decision makers (DM) for specific situations, where there is an increasing level of uncertainty about the problem at hand and where there is a high impact relative to the correct decisions to be made. DSS's offer decision makers a more stable solution to solving the semi-structured and unstructured problem

Decision Support Using Simulation for Customer-Driven Manufacturing System Design and Operations Planning
No full textManufacturing, engineering and production management decisions involve the consideration of multiple parameters. These often complex, interdependent factors and variables are too many for the human mind to cope with at one time. Agile production needs a management and evaluation tool for production changes, manufacturing system development, configuration and operations planning. A decision support system based on manufacturing simulation is one suitable solution. Discrete Event Simulation (DES) has mainly been used as a production system analysis tool to evaluate new production system concepts, layout and control logic. Recent development has enhanced DES models for use in the day-to-day operational production planning of manufacturing facilities. These "as built" models provide manufacturers with the ability to evaluate the capacity of the system for new orders, unforeseen events such as equipment downtime, and changes in operations. After a simulation model has been built, experiments are performed by changing the input parameters and predicting the response. Experimentation is normally carried out by asking "what-if" questions and using the model to predict the likely outcome. A simulation-based Decision Support System (DSS) can be used to augment the tasks of planners and schedulers to run production more efficiently. This chapter sheds light on development challenges and current development efforts to solve these challenges for this data and model-driven DSS. The major challenges are: 1) data integration, 2) automated simulation model creation and updates, and 3) visualisation of results for interactive and effective decision making

How technology can improve the efficiency of excavator-based cable harvesting for potential biomass extraction - A woody productivity resource and cost analysis for Ireland
No full textTwo cable logging systems were reviewed to compare the efficiency of potential biomass extraction from remote forest sites in Ireland based on productive machine hour (PMH) and unit cost of operation (€/m3). Three operational scenarios (SC) were analysed where SC I was a three man crew operation (choker setter, the carriage operator and unhooking chokers). SC II was a variation of this with a two man crew operation. SC III was operating radio controlled chokers there was a two man crew (choker setter and carriage operator). The study aims to assess how operations in Ireland perform against previous known cable studies to determine whether the cost of timber extraction on remote forest sites inaccessible for mechanised felling, has a future given the increased demand for wood fibre in Ireland, both from the sawmilling industries and the wood for energy sector. The volume per PMH was recorded at 17.97 for SC I, 15.09 for SC II and 20.58 m3 for SC III. The difference in productivity versus SC III remote controlled chokers is 5.49 m3/PMH for SC II crew and 2.61 m3/PMH for SC I. The decrease in total volume extracted from SCs I and II versus SC III was recorded at 15.69 m3 (15%) and 32.97 m3 (36%) product respectively. In value terms, the unit cost (€/m3) varied from 6.29 (SC I) to 6.43 (SC II) to 4.57 (SC III). When looking at the production unit costs of normal wood energy supply chains in Ireland, the figures are similar ranging from 3.17 €/m3 to 8.01 €/m3. The value of the end product of course will always determine which market the eventually goes to but given that cable log wood fibre has been unthinned and unmaintained then the biomass
sector may be an ever increasing demand point in the search for increased woody biomass
given that the unit costs can be competitive with other wood energy supply chains.Science Foundation IrelandNational Council for Forest Research and Development in Ireland (COFORD

We have the pleasure of presenting you with this explanatory dictionary-glossary of in-forest biomass processing related terminology. The explained terms are divided into five categories as follows: description of stand and raw material, logging, processing, haulage and units. In each of these fi elds, the terms are presented in alphabetical order. Where synonyms are identified, an explanation is given of the preferred term and the term which, in the authors’ opinion, is obsolete and inadequate, refers to the priority term. The interpretation of some terms is supported with illustrations in the figure section.European Commission - Seventh Framework Programme (FP7
