Application of multicriterional analysis on the selection of the location for disposal of communal waste

Abstract This paper presents the application of the promethee methods and geometrical representation of multicriterional analysis ( gaia ) on an actual example of the selection of the location for the disposal of communal waste in the region Gorenjska in Slovenia. In addition to the model presentation the paper deals with the application of the method in the function of decision making on investments which is necessary to make the actual existing locations environmentally acceptable.

GIS - based DSS for priority setting in humanitarian mine - action

Mine contamination is one of the main obstacles to economic recovery and other types of progress in mine‐affected countries. Therefore, the primary goal of humanitarian demining operations is to clear all suspected minefields and restore them so as to make them available for their previous use. The customary financial shortfall results in the need for priority setting in the mine removal process. This paper describes and investigates a new approach to priority setting within mine action, with the introduction of a hierarchic GIS‐based decision support system (DSS). The proposed DSS is aimed at determining the objective priorities required to reduce the risks stemming from mine contamination. DSS is based on a combination of GIS analysis and a multicriteria method in order to enable efficacious mine action management, namely setting humanitarian demining priorities in order to optimally reduce the risk caused by mines. GIS is outlined as a powerful tool for the generation of aggregated information used in multicriteria analysis, as is the link between hierarchic decision levels in the proposed DSS. The results of a demonstration of the proposed GIS‐based DSS on mine‐affected water resources in Croatia are supplied.

Application of multicriterional analysis to the ranking and evaluation of the investment programmes in the ready mixed concrete industry

Abstract With the objective of providing a cement market, the cement industry in Yugoslavia is making plans to invest in the ready-mixed (RM) concrete industry. The realization of the RM concrete plants network is to be effected by integrating the existing plants and by constructing new ones. Such an extensive investment program presents numerous solutions. These have to meet the requirements dictated by various criteria. Multicriteria analysis is a realistic approach to this complex problem which includes some conflicting criteria. We have found that the PROMETHEE method is well adapted to this problem, since its flexibility enables the decision-maker to express his preferences more precisely, and results can be easily obtained by a stability problem. In this paper, the problem is formulated, the criteria are estimated and quantified, and location planning is obtained by using the PROMETHEE methodology. The obtained solutions are discussed and the computational results are given.

An evaluation of multicriteria analysis for DSS in public policy decision

Abstract The definition of the routes for the future Adriatic highway along the Adriatic coast has given rise to a great number of discussions, dilemmas, conflicting interests and attitudes, considering the two alternatives of the route, i.e. the coastal and the continental one. Since the ‘classical’ methods (primarily feasibility studies), have yielded almost the same results for both alternatives, the government (the road management authorities) have decided upon the application of multicriteria analysis for finding the optimal alternative of the highway route. Applying multicriteria analysis, i.e. the PROMETHEE method and the program package GAIA, it was attempted to ‘model’ a very complex structure of the problem and by engaging a team of experts to make as objective as possible the evaluation procedure and the weight pondering of each group of criteria which were evidently in conflict. The influence exerted by parameters of each criterion weight on the obtained solution was estimated by different scenarios of weight pondering, and by an analysis of the stability of criterion weights. The paper also presents further development of the methodology used for deciding on alternative solutions of the highway route according to the DSS concept. Consequently, further phases include the integration of the data bases, model bases and the dialogue generator with the graphic interpretation of the results.

Decision Support System for emergency management on motorway networks

This article presents an approach to problems of emergency management on motorways using a Decision Support System (DSS). The advantages of this approach in comparison with conventional operational methods are acceptable data management costs provided by spatial data already stored in a Geographical Information System (GIS), generation of new data using various spatial functions as well as transparency for all emergency services. DSS deploys GIS in conjunction with other decision models thus becoming a powerful tool for the coordination of all participants in a decision-making process during emergency situations giving them a more cooperative surrounding. For the purpose of more efficient emergency management on motorways, the main idea is to provide an organisational support by combining GIS with decision models in order to provide an effective spatial DSS concept.

Application of multicriterional analysis to the problem of reinforcement improvements in concrete works

Abstract The paper present the methodology for selecting the most suitable (optimal) solution out of several possible alternatives for the development of reinforcement works. The selection was performed according to several different technical and nontechnical criteria employing the Electre method. It also presents the procedure for establishing alternative solutions using system analysis.

Systemic Approach to the Integration of Motorway Networks into European Emergency Number 112

In recent years, the world has focused on the protection of critical infrastructures, especially in the field of transportation, which is particularly critical considering traffic accidents. This paper presents the procedure for categorisation of the efficiency level of an existing motorway emergency system, as well as presenting the most important basis for the design of a new emergency management system based on Information and Communication Technology (ICT) tools, geographic information systems and systems for operative procedures. The whole motorway emergency management system should be improved with eCall technology. Using the systemic approach and taking into account the available emergency services, such as police, medical emergency services and fire brigades, a procedure for making the optimal schedule is proposed. For each emergency service, the fastest-route principle is defined, taking into account available road networks, traffic intensity, road closures caused by accident, etc.

The Application of Goal Programming for Determination of Optimal Concrete Mixes

Most optimization problems can be mathematically formulated as the problem of bound extremes with linear or non-linear relations. With linear relations linear programming (LP) models can be used and these have been successfully used to solve a great number of practical problems. Determination of the optimal mix for obtaining afinishedproduct with the required properties and quality is one of those problems by what is known in literature as the mix model.The model is based on the fact that in some mixes the quantity of one or two ingredients can vary independently within the given constraints assuring that the quality of the finished product will satisfy the given requirements. Using these constraints it is possible to determine such ratios between ingredients to ensure optimal cost efficiency or optimal economic or technical-technological solutions to produce the final product (Bonacci O., Mladineo N., 1981).
