Role of Economic Assessment in Selecting among Mass Transit Construction Alternatives

摘要

In this report, a Leontief input-output model with dynamic capabilities is developed and applied to the assessment of the economic impact of mass transit construction, namely, the relationship of economic impact of mass transit and construction schedule alternatives. The model developed for this study, Core Sequential Interindustrial Model (CORSIM) has the additional feature of developing a dynamic picture, referred to as the impact chronology as opposed to the static summary provided by the regular input-output model. Chapter 2 of this report discusses computer modeling techniques; Chapter 3 develops the mathematical basis of CORSIM and illustrates its relevance to the economic impact of a construction project; Chapter 4 presents the application of CORSIM to construction scheduling; and Chapter 5 provides the conclusions and recommendations to the study.
