1、山东建筑大学毕业设计外文文献及译文外文文献：Study on Human Resource Allocation in Multi-Project Based on the Priority and the Cost of ProjectsLin Jingjing , Zhou GuohuaSchoolofEconomics and management, Southwest Jiao tong University ,610031 ,China Abstract-This paper put forward the affecting factors of projects priority
2、. which is introduced into a multi-objective optimization model for human resource allocation in multi-project environment . 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 .Then
3、a Genetic Algorithm to solve the model was introduced. Finally, a numerical example was used to testify the feasibility of the model and the algorithm.

4、hallenge of multi-project management, which has been the focus among researches on project management. 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 the di
5、fferent resource demands and to shorten the projects duration time with resources constrained ,as in 1.For many enterprises ,the human resources are the most precious asset .So enterprises should reasonably and effectively allocate each resource , especially the human resource ,in order to shorten t

Reference 1 designed an iterative algorithm and proposed a mathematical model of the resource-constrained multi-project
7、scheduling .Based on work breakdown structure (WBS) and Dantzig-Wolfe decomposition method ,a feasible multi-project planning method was illustrated , as in 2 .

These literatures reasonably optimized resources allocation in multi-project, but all had the same prerequisite that the projects importance is the same to each other .This paper will analyze the effects of
10、projects priority on human resource allocation ,which is to be introduced into a mathematical model ;finally ,a Genetic Algorithm is used to solve the model. 2. EFFECTS OF PROJECTS PRIORITY ON HUMAN RESOUCE ALLOCATION AND THE AFFECTING FACTORS OF PROJECTS PRIORITYResource sharing is one of the main
11、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, can the projects with
12、 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 influence on the enterprises
13、 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 technology and manageme
14、nt; 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 ENVIRONMENT3.1 Problem DescriptionAccording to the constraint theory, the enterprise should strictly differentiate
15、 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 simplify the problem, we suppose that that
16、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 ways during a certain period .when resource conflict among parallel projects occurs, we may allocate the human resource to multi-project according to projects priorit
