Scheduling Model for Multiple Constrution Projects

From the end of 20th century, developed countries are making efforts to regenerate old downtown areas of their cities. Urban regeneration program can be simplified as the demolition of existing deteriorated buildings and the construction of multiple new facilities. To maximize the benefit of the construction program within the restricted time and the limited financial resources, each project needs to be carefully planned considering the incomes and the expenses of the whole construction program. In this study, 3 types of scheduling situations, that are smoothing periodic loan, reducing program duration, and matching cost to budget are proposed under the constraints of time and budget. And concept models to find out optimal arrangement of projects’ schedule for satisfying the goal of each scenario are presented.
