SOLUTION TO THE MULTIOBJECTIVE MODEL USING GENETIC ALGORITHM The multiobjective optimization problem is quite mon .Generally ,each objective should be optimized in order to get the prehensive objective optimized .Therefore the weight of each subobjective should be considered .Reference [8] proposed an improved ant colony algorithm to solve this problem .Supposed that the weights of the two optimizing objectives are α and β ,where α+β=1 .Then the prehensive goal is F* ,where F*=αF1+βF2. The Principle of Geic Algorithm Geic Algorithm roots from the concepts of natural selection and geics .It’s a random search technique for global optimization in a plex search space .Because of the parallel nature and less restrictions ,it has the key features of great currency ,fast convergence and easy calculation .Meanwhile ,its search scope is not limited ,so it’s an effective method to solve the resource balancing problem ,as in [9]. The main steps of GA in this paper are as follow: (1) Encoding An integer string is short, direct and efficient .According to the characteristics of the model, the human resource can be assigned to be a code object .The string length equals to the total number of human resources allocated.

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 Geic 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—Geic Algorithm, Human Resource Allocation, Multiproject’s project’s priority . 1. INTRODUCTION More and more enterprises are facing the challenge of multiproject management, which has been the focus among researches on project management. In multiproject environment ,the share are petition 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 proble
