Abstract :
During the past two decades, some industries have been moving towards project-centered
systems in many modern countries. Therefore, managing simultaneous projects with
considering the limitations in resources, equipment and manpower is very crucial. In the real
world, project-based organizations are always facing with two main important features.
First, the construction projects are decentralized and their distances are long, and second,
there are several construction projects undertaken at different time periods. Therefore,
appropriate selection of projects with regard to the capabilities of the organization may lead
with increasing an expected profitability. This paper investigates the multi-period
decentralized multi construction-project and scheduling problem subject to resource
constraints, optimal resource pool location, deterioration and batch ordering of
nonrenewable resources altogether, for the first time in the literature. In order to describe the
problem under consideration in this paper and obtaining the optimal solutions, a mixed
integer linear programming model is developed. Finally, the impact of decision integration
on the profit profile of an organization is comprehensively investigated by solving numerical
examples and through developing some heuristic methods.
