Abstract

In order to take up new challenges regarding the management of a wide range of parameters impacting the risk of accidents at rail crossings on the Belgian railway network, we have developed an innovative multicriteria decision making framework based upon the pairwise comparison PROMETHEE (Preference Ranking METHod for Enrichment and Evaluation). The framework allows the evaluation of a global risk index based upon a wide range of indicators thanks to a “two-steps” aggregation process including the definition of sensitivity parameters. Around 50 indicators are classified into three main clusters related to three specific risk sources, namely: the road network, the rail network and the town planning related aspects. These three clusters are then aggregated into the final risk index. Within the frame of the Belgian rail network, this index provides the responsible public body with an actual strategic investment handbook regarding the most risky locations. An user friendly excel tool has been developed in order to make that new decision framework easily understandable by the final users.

比利时铁路网安全措施投资管理的综合风险指数的发展

为了应对有关管理影响比利时铁路网络铁路道口事故风险的各种参数的新挑战，我们基于两两比较PROMETHEE(偏好排序法)开发了一种创新的多标准决策框架。该框架通过包括定义敏感性参数在内的“两步”汇总过程，可以根据广泛的指标评估全球风险指数。大约50个指标被分为与三个具体风险源相关的三个主要集群，即:公路网、铁路网和与城镇规划相关的方面。然后将这三个聚类汇总成最终的风险指数。在比利时铁路网络的框架内，该指数为负责任的公共机构提供了有关最危险地点的实际战略投资手册。一个用户友好的excel工具已被开发，以使新的决策框架易于理解的最终用户。
