Abstract----This paper put forward the a ffecting factors of

project’s priority. 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 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.

Index Terms—Genetic Algorithm, Human Resource

Allocation, Multi-project’s project’s priority .

1.INTRODUCTION

More and more enterprises are facing the challenge 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 , it’s

critical to schedule projects in order to

satisfy the different 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 the time and cost of projects and to increase the

benefits .Some literatures have discussed the resource allocation

problem in multi-project environment with resources

constrained. Reference [1] designed an iterative algorithm and

proposed a mathematical model of the resource-constrained

multi-project scheduling .Based on work breakdown structure

(WBS) and Dantzig-Wolfe decomposition method ,a feasible

multi-project planning method was illustrated , as in [2] .

References [3,4] discussed the resource-constrained project

scheduling based on Branch Delimitation method .Reference [5]

put forward the framework of human resource allocation in

multi-project in Long-term ,medium-term and short-term as well

as research and development(R&D) environment .Based on GPSS

language, simulation model of resou rces allocation was built to

get the project’s duration time and resources distribution, as in

[6]. Reference [7] solved the engineering project’s resources

optimization problem using Genetic Algorithms. These

literatures reasonably optimized resources allocation in multi-project, but all had the same prerequisite that

the project’s importance is the same to each other .This

paper will analyze the effects of project’s 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 PROJECT’S PRIORITY

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. 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 project’s priority into

three categories ,as the project’s benefits ,the complexity of

project management and technology , and the strategic influence

on the enterprise’s 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 project’s priority weight; I refers to the

benefits of the project; c refers to the complexity of the project,

including the 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 ENVIRONMENT

3.1Problem Description

According to the 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 times and priority.

To simplify the problem, we suppose that that three exist

several parallel projects and a shared resources storehouse, and
