Assume that there are three projects with the same work ,and the priority weights have been put forward .There is only one critical path in each project . The data we have known are shown in Table 1. Table 1 Data of the Three Projects Project Priority weight w tE Cost loss(human yuan/day) Workload (person*day) 1 10 100 100 2 8 150 80 3 12 80 120 The steps of Geic Algorithm to solve the model are as follow: Step1: An integer string is adopted .Encode with [0,1,2] for there are three projects .The length of the chromosome is 16 ,the total number of human resource to be allocated . Step 2: The initial population size is 50. Step 3: Doing geic operation .Adopt Roulette Wheel and Elitist tactic to determined selection operator .The offspring can be yielded by uniform crossover .The mutation operator can be determined by uniform mutation .We assume that the mutation probability equal to . Step 4: Adopt the maximum population size is 100 when terminated. After the puter simulation, we can obtain the Pareto results with different importance weights of the two objective functions, as shown in Table 2 : Table 2 The Solution Result of the Model R1* R2* R3* F1(Hundred Yuan) F2(Day) α=1,β=0 6 5 5 α=,β= 7 5 4 α=,β= 8 4 4 建筑大學(xué)畢業(yè)設(shè)計外文文獻及譯文 9 α=,β= 10 3 3 0 From table 2 we can learn that , when α and β change ,the result is different .However we can obtain a series of Pareto results. 6. CONCLUSION Human resource allocation in multiproject environment is a plicated problem .This paper analyzes the importance of project’s priority in resource allocation and establishes a human resource allocation model based on priority and cost of projects .Finally, geic Algorithm is adopted to solve the model. During the construction process of the allocation model, we have put forward some hypotheses in order to simplify the problem .However, when the enterprises practically allocate the resources, hey will face more plexity, which is the focus of our future study. 建筑大學(xué)畢業(yè)設(shè)計外文文獻及譯文 10 中文翻譯： 在項目優(yōu)先權(quán)和成本的基礎(chǔ)上對多項目中人力資源配置的研究 林 晶晶 ，周 國華 中國 西南 交通 大學(xué)經(jīng)濟和管理 學(xué)院， 610031 摘要 本文提出項目優(yōu)先次序 的 影響因素， 為多項目環(huán)境配置 人力資源引入一個多目標(biāo)優(yōu)化模型。 c refers to the plexity of the project, including the technology and management。建筑大學(xué)畢業(yè)設(shè)計外文文獻及譯文 1 中文 3550 字 外文 原文 Study on Human Resource Allocation in MultiProject Based on the Priority and the Cost of Projects Lin Jingjing , Zhou Guohua SchoolofEconomics and management, Southwest Jiao tong University ,610031 ,China AbstractThis paper put forward the affecting factors of project’s priority. which is introduced into a multiobjective optimization model for human resource allocation in multiproject 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 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 liter
