Abstract: Slums are informal areas that are illegally developed on property of the State with no physical planning. Accordingly, governments adopt various intervention strategies to replace or upgrade these slums. However, implementing these strategies is often faced by several planning and constructability challenges, because the slums areas that should be upgraded (1) are already occupied by resident families; and (2) are often characterized by unplanned and extremely crowded transportation networks. Accordingly, the construction period of these upgrade projects can result in significant social disruption to resident families and requires protracted timelines and additional budgets. The objective of this paper is to present a multi-objective optimization model that is capable of accelerating the delivery of urgent redevelopments while minimizing construction costs and socioeconomic disruptions to slum dwellers. An application example is presented to demonstrate the model capabilities and is followed by a discussion of formulation challenges.
