摘要

Environmental performance criteria currently represent major decision factors in civil engineering projects, including pipeline construction. This paper presents a framework based on systems modelling and multicriteria decision analysis (MCDA) that captures different setups of pipeline installation techniques and the environmental impacts expected from different execution scenarios. A model is developed via SysML using the principles of systems modelling and engineering to capture the interactions of the pipeline as a product, the installation technique utilized, together with the environment. A TOPSIS-based MCDA module permits selecting the optimum alternative among construction alternatives. Open cut trenching and microtunneling are exemplified and a case study is provided where both techniques are evaluated in terms of environmental impacts. The contribution of this work is providing a structured and versatile framework that properly captures the interactions of different pipeline installation techniques and the environment, enabling the quantification of environmental impacts to a high degree of precision. The capacity to model different scenarios allows comparison and selection of the most suitable alternative.

7. Competing Recombinant Technologies for Environmental Innovation: Extending Arthur’s Model of Lock-in Abstract: This article presents a model of sequential decisions about investments in environmentally dirty and clean technologies, which extends the path-dependence framework of Arthur (1989). This allows us to evaluate if and how an economy locked into a dirty technology can be unlocked and move towards the clean technology. The main extension involves the inclusion of the effect of recombinant innovation of the two technologies. A mechanism of endogenous competition is described involving a positive externality of increasing returns to investment which are counterbalanced by recombinant innovation. We determine conditions under which lock-in can be avoided or escaped. A second extension is â€œsymmetry breakingâ€ of the system due to the introduction of an environmental policy that charges a price for polluting. A final extension adds a cost of environmental policy in the form of lower returns on investment implemented through a growth-depressing factor. We compare cumulative pollution under different scenarios, so that we can evaluate the combination of environmental regulation and recombinant innovation. [O] .
