Abstract：The selection and scheduling of interrelated alternatives has many applications in engineering, management, operations research and other important fields but is still insufficiently developed, unlike the well-developed methods available for mutually-exclusive or independent alternatives. Such methods will be presented for evaluating, selecting, sequencing and scheduling interrelated alternatives for developing transportation systems, while dealing with uncertainties and financing considerations. Application-specific methods for evaluating various systems are combined with general algorithms for selecting and scheduling improvements. Applications will be discussed for road network improvements (e.g. widened links, new links and expanded intersections), public transportation systems, inland waterways and airports.
