This paper presents a systematic and sustainable approach to nonurban road network maintenance management based on the integration of multicriteria decision-making methods and methods of monitoring and control in the service of planning, implementation and monitoring and control as the basic management processes. This approach is based on the developed maintenance management model for nonurban road network, which consists of a weighting sub-model based on the AHP method, a priority road ranking sub-model based on TOPSIS method and a monitoring and control sub-model based on the combination of TOPSIS and Earned Value Analysis (EVA). The described model with all its supporting sub-models is tested on the case study of the regional road network of Herzegovina-Neretva County. The analysis of the obtained results shows the effectiveness of the presented approach to road maintenance management and the possibility of its practical application.
New Optimization Model for Road Network Maintenance Management
Procedia - Social and Behavioral Sciences, 2012
This paper presents a Multi-Objective Decision-Aid Tool (MODAT) tested with data from the Estradas de Portugal's Pavement Management System (PMS). Nowadays, the PMS used by the main Portuguese concessionaire (Estradas de Portugal, S.A.) uses a deterministic section-linked optimization model with the objective of minimizing the total expected discounted costs over the planning time-span while keeping the road pavements within given quality standards. The MODAT considers three different possible goals: minimization of agency costs (maintenance and rehabilitation costs); minimization of user costs; and maximization of the residual value of pavements. This new approach allows PMS to become interactive decision-aid tools, capable of providing road administrations with answers to "what-if" questions in short periods of time. The MODAT also uses the deterministic pavement performance model used in the AASHTO flexible pavement design method that allows closing of the gap between project and network management. The application of the MODAT is illustrated with a case study involving the main road network of Castelo Branco, a district of Portugal.
Study of Road Maintenance Program Priority, Using the Analytical Network Process
IOP Conference Series: Materials Science and Engineering, 2017
On the implementation of the maintenance roads works in Nias, there has been no standardized system, in terms of work priority order. The purpose of this study was to determine the priority of strategic road order, with Analytical Network Process (ANP), which is based on technical criteria as the basis for determining the priority policy for development or maintenance of roads in Nias. As the results, several criteria based on stake holder judgment, which can be used as the basis for maintenance priority program of road, respectively are: accessibility 30.87%; regional connectivity 25.33%; movement needs 17.90%, regional strategic development purposes 13,49%, and road condition 12:42 %.

RCM and AHP hybrid model for road network maintenance prioritization
The Baltic Journal of Road and Bridge Engineering, 2015
Category1 defects such as potholes significantly accelerate structural deterioration and pose imminent hazards on trunk road networks. Frequent occurrences of category1 defects have increased service disruptions on trunk road networks. Road maintenance agencies are now required to effectively prioritize trunk road network category1 defects maintenance works. However, existing road maintenance prioritization methods such as value engineering and traditional expert judgment methods have limitations. Value engineering is resource and time intensive thus best suited for project level prioritization and traditional expert judgments are subjective and lack audit trails. In an attempt to address the limitations of above methods, this study presents a Reliability Centered Maintenance and Analytical Hierarchy Process based hybrid model for trunk road network maintenance prioritization. The proposed hybrid model is used to establish failure diagnostic and Multi-criteria Decision Making respec...
Multicriteria Analysis Method for Pavement Maintenance Management
Transportation Research Record, 2002
Multi criteria analysis provides a systematic framework for breaking a problem into its constituent parts in order to understand the problem and consequently arrive at a decision. MCA provides a means to investigate a number of choices or alternatives, in light of conflicting priorities. By structuring a problem within the MCA framework, alternatives may be ranked according to pre-established preferences in order to achieve defined objectives. The paper describes a method developed for providing a multi-criteria analysis framework within HDM-4. This has been done in order to include other factors such as social benefits, environmental effects, safety impact, strategic importance of roads, etc., within a unified decision-making framework. The Analytic Hierarchy Process method has been selected for implementation in HDM-4 because it systematically transforms the analysis of competing objectives to a series of simple comparisons between the constituent elements. In particular, the approach does not require an explicit definition of trade-offs between the possible values of each attribute (i.e. it is not necessary to build utility functions), and it allows users understand the way in which outcomes are reached and how the weightings influence the outcomes.
Decision Support System to Urban Infrastructure Maintenance Management
Organization, Technology & Management in Construction, 2009
Life-cycle management of urban infrastructure projects is very complex process from both management and economic aspects. Focus of this research is on urban infrastructure maintenance phase of a life-cycle, especially on decision making in maintenance problems. Urban infrastructure maintenance management deals with complex decision making process. The reasons for a complexity are: lots of participants, multi- disciplinarity, huge quantity of information, limited budget, conflict goals and criteria. These facts indicate that decision making processes in urban infrastructure management undoubtedly belong to ill-defined problems. In order to cope with such complexity and to help project managers during decision making processes this research proposes an application of multicriteria methods. Multicriteria methodology proposed herein is applied on priority setting problem. It starts with goal analysis followed by definition of urban infrastructure elements and development of adequate criteria set. Evaluation of criteria importance (weights) is based on a set of experts’ opinions processed by AHP method. An assessment of maintenance conditions of urban infrastructure elements is provided trough monitoring process. The way of using proper forms and procedures for data collection is presented as well. All collected data are processed by PROMETHEE multicriteria methods. The main result of a multicriteria process is priority maintenance list for urban infrastructure elements. The methodology is tested on road infrastructure of town of Split.
District road maintenance priority using analytical hierarchy process
EXPLORING RESOURCES, PROCESS AND DESIGN FOR SUSTAINABLE URBAN DEVELOPMENT: Proceedings of the 5th International Conference on Engineering, Technology, and Industrial Application (ICETIA) 2018
The deterioration rate of district roads is the highest of all Indonesian road networks. Road maintenance budgetary constraint is faced by almost all of the district roads in Indonesia. Road maintenance prioritization should be a challenge in an attempt to optimize the use of the existing resources. Analytical hierarchy process (AHP) is widely used as an alternative method to determine the district road maintenance priority. The objective of the present study is to evaluate the district road maintenance priority using AHP. The research was conducted in Malang Regency and Pasuruan Regency. Four criteria were used for performing AHP, namely: road conditions, traffic, land use, and economics. The results showed that there were differences in the arrangement of the criteria in preparing road maintenance priorities. The road conditions criteria are the first priority in Pasuruan Regency, followed by traffic, economics, and land use. It is different from Malang Regency where road condition becomes the first criterion, followed by traffic, land use, and economics. AHP can be used to prioritize district road maintenance although there may be differences in the arrangement of criteria in preparing road maintenance priorities for each regency/district.
Sustainable Maintenance of low level road network
MATEC Web of Conferences, 2018
Main goal of Road Network Management System is to ensure safety and continuity of road traffic on road network with low intensity and lower technical requirements. This is achieved with pavement management system (main component of road network management system). Most countries developed custom Pavement management systems (PMS) based on deterministic or probabilistic approach. Local road administrators of low level road networks often lack the software equipment such as HDM-4, RoSy, Exor, etc. These and similar PMS Most PMS, however effective, are often cumbersome, demanding in regard to energy, know-how and software equipment. The majority of local road administrators of rural road networks thus resort to non-effective reactive maintenance strategies. This article describes an easy to use method, based on predetermined maintenance repair & rehabilitation standards. Secondly, a simple method, based on road user cost, is introduced that administrator can use to prepare a list of road section eligible for repair according to their repair priority.
Multicriteria Group Decision-Making Technique for a Low-Class Road Maintenance Program
Low-class roads substantially differ from main roads in terms of extensiveness, databank availability, and profitability, which stresses the need for an extraordinarily sophisticated decision-making mechanism for maintenance programs. However, road transportation decision-making administrators in third-world countries such as Iran are occasionally neither well educated in their area of activity nor especially eager to benefit from specialist advice. This usually leads to costly errors in the process of individual decision making. One way to obviate these grave errors could be to incorporate group decision-making techniques into the administrative agenda. The combined Conference-Delphi-analytic hierarchy process (AHP) model employed here to prioritize the low-class roads in Gilan for maintenance, improvement, and upgrading, profoundly incorporates specialist advice and could serve as a counteracting approach in this regard. The preliminary procedures including the Conference and the Delphi survey were employed to determine the list of the specialists for the AHP and the criteria which were then fed into the AHP. The results indicate a significant contrast between conventional individualistic decisions and those made through incorporating systematic specialist comments using our model.
Simplified Rapid Assessment Approach to Road Network Management
Transportation Research Record, 1996
A simplified approach, using limited network-specific data and the recently developed World Bank HDM Manager, was applied to the highway network of Peru to provide interim guidelines on appropriate standards and policies to be implemented, pending the results of a more elaborate study involving a full-scale road condition and traffic inventory. The design of the methodology is described, as is its application to define the best maintenance strategies for paved and unpaved road networks. The order of magnitude of the level of expenditures required is determined, and a tentative prioritization scheme for road activities is developed. Peru, with an area of 1.3 million km 2 and a population of 22 million, is emerging from a decade-long neglect of its road network combined with debilitated highway institutions. Whether the national road system (15 700 km) or the departmental and feeder road systems (14 500 and 39 800 km, respectively), the maintenance condition of the road network has been extremely poor during the past decade. The absence of appropriate planning tools and programming procedures, unreliable funding mechanisms, and weak institutional structures are at the root of the large amount of deferred maintenance that can be observed on the highway system. Over the past 3 years, the government has been serious about addressing this problem and has assigned the highest priority to the road subsector. The highway rehabilitation projects being implemented with the support of the World Bank and the Inter-American Development Bank point toward a comprehensive study to design appropriate strategies and a rational 5-year road expenditure program based on an updated road inventory and using the World Bank Highway Design and Maintenance Model (HDM-III) and the Expenditure Budgeting Model (EBM). Pending the results of these investigations, a simplified approach applying the recently developed HDM Manager was deemed useful for assisting Ministry of Transport officials in formulating better their maintenance standards and budgets in the short term (the next couple of years).
