  1. 1. Life Cycle Costing in Road Planning and Management : A Case Study on Collision-free Roads

    Författare :Jonas Wennström; Håkan Sundquist; Tommy Edeskär; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collision-free road; design; infrastructure; investment; life cycle costing; life cycle cost analysis; maintenance; management; operation; planning; road; sustainability;

    Sammanfattning : Construction of infrastructure does not only mean large capital investments but also future costs to operate and maintain these assets. Decision making in planning and design of roads will impact the need of future operation and maintenance activities. LÄS MER

  3. 2. A Microdata Analysis Approach to Transport Infrastructure Maintenance

    Författare :Kristin Svenson; Lars Rönnegård; Karin Edvardsson; Nasir Gharaibeh; Högskolan Dalarna; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Transport Infrastructure Asset Management; Transport Infrastructure Maintenance; Statistical Modeling; Microdata Analysis; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : Maintenance of transport infrastructure assets is widely advocated as the key in minimizing current and future costs of the transportation network. While effective maintenance decisions are often a result of engineering skills and practical knowledge, efficient decisions must also account for the net result over an asset's life-cycle. LÄS MER

  4. 3. Slab Frame Bridges : Structural Optimization Considering Investment Cost and Environmental Impacts

    Författare :Majid Solat Yavari; Costin Pacoste-Calmanovici; Raid Karoumi; Mario Plos; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slab frame bridge; Structural design; Cost optimization; Optimization of environmental impact; Life cycle assessment; Genetic algorithm; Pattern search method; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : This research encompasses the automated design and structural optimization of reinforced concrete slab frame bridges, considering investment costs and environmental impacts. The most important feature of this work is that it focusses on realistic and complete models of slab frame bridges rather than on optimization of only individual members or sections of a bridge.

    Sammanfattning : This dissertation is concerned with the planning processes in transportation and infrastructure investments and the aim is to improve risk assessment, risk valuation and risk management. Many of the results presented in this thesis are also applicable to a wider range of questions... LÄS MER

  7. 5. Life-Cycle Costing : Applications and Implementations in Bridge Investment and Management

    Författare :Mohammed Safi; Raid Karoumi; Håkan Sundquist; Jan-Eric Nilsson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Bridge; Cost; Life Cycle Cost Analysis; Procurement; Investment; Management;

    Sammanfattning : A well-maintained bridge infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements sustainably and cost-effectively is challenging. Bridge investment and management decisions generally involve selection from multiple alternatives. LÄS MER
