A Research On Real Estate Multiple Projects Development Decision Making Method With Resource Constraints

At present,the regional and cross-regional multi-project development task is already normal in China's real estate development enterprises,and a single real estate investment decision-making method in the past has been unable to meet the real needs of multi-project real estate development decision-making.Therefore,it is necessary to design a multi-project development decision-making method which can make multi-project primary selection and project porfolio selection and schedule arrangement under the constrained resources of real estate enterprises.Based on current concepts,combined with the characteristics and process of project portfolio management and project progress concept and method and real estate multi-project development decision-making,the paper designs a comprehensive real estate multi-project development decision-making process and methods,which can be divided into two parts.The first part is to carry out real estate multi-project development enterprise strategy development and project primary selection,applying a variety of internal and external environment analysis methods and multi-layer screening method to initially select project portfolio that aligns with the enterprise strategic development and business decision-making objectives.The second part is to add the constraints of enterprise resource restriction and external restriction after we have konwn the preliminary screening result of project information and business decision objectives,to build a mathematical model of optimal project portfolio selection and schedule,and use flexible Constraint Programming to solve the optimal selection of the project plan and the schedule.The numerical analysis proved the validity of the model and the flexibility of the algorithm.Finally,through a case study,this paper proves that this model can provide the appropriate decision-making process for different enterprise situation and enterprise strategy and calculate the optimal project portfolio and development schedule.In this paper,it provides multi-project decision-making method under the conditions of resource constraints to help enterprises choose projects from a number of projects and conduct project portfolio selection and scheduling.Through mathematical modeling and Constraint Programming algorithm,it can easily solve the optimal results for a variety of decision-making goals quickly,where there is a strong practical significance.At the same time,the proposal of real estate multi-project decision-making method makes up the combination of project portfolio management,resource constrained project scheduling problems,optimization algorithm and real estate multi-project development,and proposes a combination of real estate multi-project selection and scheduling model and provides a theoretical basis for further exploration of resource constrained real estate multi-project development.
