EFFECTS OF PROJECTS PRIORITY ON HUMAN RESOUCE ALLOCATION AND THE AFFECTING FACTORS OF PROJECTS PRIORI

11、TY Resource sharing is one of the main characteristics of multi-project management .The allocation of shared resources relates to the efficiency and rationality of the use of resources .When resource conflict occurs ,the resource demand of the project with highest priority should be satisfied first.

12、 Only after that, can the projects with lower priority be considered. Based on the idea of project classification management ,this paper classifies the affecting factors of projects priority into three categories ,as the projects benefits ,the complexity of project management and technology , and th

13、e strategic influence on the enterprises future development . The priority weight of the project is the function of the above three categories, as shown in (1). W=f(I,c,s) (1) Where w refers to projects priority weight； I refers to the benefits of the project； c refers to the complexity of the proje

14、ct, including the technology and management； s refers to the influence of the project on enterprise .The bigger the 建筑大学毕业设计外文文献及译文 -3- values of the three categories, the higher the priority is. 3. HUMAN RESOURCE ALLOCATION MODEL IN MULTI-PROJECT ENVIRONMENT 3.1 Problem Description According to the

15、 constraint theory, the enterprise should strictly differentiate the bottleneck resources and the non-bottleneck resources to solve the constraint problem of bottleneck resources .This paper will stress on the limited critical human resources being allocated to multi-project with definite duration t

16、imes and priority. To simplify the problem, we suppose that that three exist several parallel projects and a shared resources storehouse, and the enterprises operation only involves one kind of critical human resources. The supply of the critical human resource is limited, which cannot be obtained b

17、y hiring or any other ways during a certain period .when resource conflict among parallel projects occurs, we may allocate the human resource to multi-project according to projects priorities .The allocation of non-critical independent human resources is not considered in this paper, which supposes

18、that the independent resources that each project needs can be satisfied. Engineering projects usually need massive critical skilled human resources in some critical chain ,which cannot be substituted by the other kind of human resources .When the critical chains of projects at the same time during s

19、ome period, there occur resource conflict and competition .The paper also supposes that the corresponding network planning of various projects have already been established ,and the peaks of each projects resources demand have been optimized .The delay of the critical chain will affect the whole projects duration time . 3.2 Model Hypotheses The following hypotheses help us to establish a mathematical model: (1) The number of mutually independent projects involved in resource allocation problem in multi-project is N. Each project is indicated with
