The objectives of the model were the minimum cost loss due to the delay of the time limit of the projects and the minimum delay of the project with the highest priority .The

In multi-project environment ,the share are competition of resources such as capital , time and human resources often occur .Therefore , its critical to schedule projects in order to satisfy th

EFFECTS OF PROJECTS PRIORITY ON HUMAN RESOUCE ALLOCATION AND THE AFFECTING FACTORS OF PROJECTS PRIORITY Resource sharin
11、g 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. Only after that,
12、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 the strategic influe
13、nce 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 project, including the
14、technology and management； s refers to the influence of the project on enterprise .The bigger the values of the three categories, the higher the priority is. 3. HUMAN RESOURCE ALLOCATION MODEL IN MULTI-PROJECT 毕业设计外文文献及译文 -3- ENVIRONMENT 3.1 Problem Description According to the constraint theory, th
15、e 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 times and priority. To
16、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 by hiring or any other
17、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 that the independent r
18、esources 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 some period, there occu
19、r 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 .
20、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 Qi ,while i=1,2, N. (2) The priority weights of multi-project have been determined ,which are
