||As the world’s high degree of urbanization, greenhouse gas emission by vehicles, home appliances and industrial production is increasing year by year and according to the UNEP (United Nations Environment Programme) report urban carbon-dioxide emissions accounted for 80% of total global emissions. In order to encourage the alternative energy development, Taiwan government actively promotes the subsidy for alternative energy implementation, thus making the solar energy industry booming in recent years.|
Based on the government procurement competition mechanism, the procurement competition needs to be transparent and fair. Faced with competition in the industry, companies must reduce costs and improve quality while also required to enhance the customer satisfaction. Therefore, a good engineering project control becomes the most important factor to enhance a company's competitive ability. Particularly, when professional management is getting more and more important nowadays, solar energy system’s building construction is not only limited to technology and equipment level, but also the enterprise configuration of internal human resources and outsourcing. Moreover, how to minimize cost and how to use efficient way to make the project work on schedule are the important issues for policy makers.
This study is based on a domestic solar systems engineering project, and focuses on the distribution and configuration of the limited internal and external resources of multiple projects in progress. It uses the Critical Chain Project Management in the Theory of Constraints to break through limitations. VBA programming is used to find the minimum cost of human resource conflict in the project scheduling, furthermore Arena simulation system is utilized to establish the best configuration of human resources deployment to provide decision-making mechanism. The simulation result is verified that it can really help to provide a decision-making reference to project managers to obtain the ideal scheduling and resource allocation.
