- W2260622477 abstract "Infrastructure management is well established around the world. However, its main use is for strategic planning, typically to figure it out levels of funding required to achieve and sustain target levels of service to end users. Translating strategic planning into tactical and operational planning has not been so widely explored. Often there is a disconnection between long term analysis and annual programs of works. This paper explores the mechanisms for translating results from integer programming optimization into tactical programs of works. Space and time criteria along with treatment compatibility, are used to re-allocate treatments to minimize disruptions to users by clustering together neighbor projects to happen at the same time. A corridor of 1km wide along route 1 in New Brunswick was used to illustrate the method. The strategic analysis consisted of 20 years of treatment allocation for pavements, chip-sealed roads and bridges. It was found that treatments for a tactical plan of 15 years were re-allocated into groups at years 2, 3, 5, 7 and 10. Clusters at years 2 and 3 were separated by a distance superior to the maximum space opening criteria specified and therefore were not clustered into one group. Coordinated program of works resulted in suboptimal plans affecting more largely chip-sealed roads (33% away from optimal) and then pavements (17% away), bridges remained less affected with values for total bridge condition much closer (9% away) to optimal uncoordinated values of such objective." @default.
