It is a research topic belonging to this study. Human resource management （HRM） can be described with performance focus and talent management. This study presents a new perspective in talent management. Firstly, Talent management may be described with fulfilling organizational positions by bets talents, because talents further performance of departments and performance of firm. Firm has departments, such as production department, marketing departments, finance department, and etc.. This study suggests simplex method for talent management for practitioners. It identifies research question and has two propositions that simplex may be used in talent management. Secondly, study depicts linear of American HRM It is based on a relationship among human resource （HR） systems, various HRM practices, and organizational performance. Linear proposition of study is that, HRM practices as a system have an impact on firm performance （goal function）.展开更多

There exist shortages in evaluating the value of the employees in an enterprise. Consequently, a lot of employees might be laid off. Hence, this paper puts forward a two-stage method for decision-making to carry out a selective plan of buyout, based on the fuzzy synthetic evaluation involing many factors impacting on human resource. Moreover, a positive analysis is also given.展开更多

Many companies which developed to a certain stage began to introduce performance management. But a lot of friends in human resources circles always hold a controversy on the effectiveness of performance management. In fact, there are problems on the methods and assessment scales. I personally think that a lot of companies use performance appraisal problem mainly occurs due to the presence misunderstanding the purpose of business resulting from the introduction of performance appraisal. For example： taking the wrong assessment methods, there is no breakdown of the work in advance, nor performed posts and responsibilities ; performance appraisal way to take a negative incentive, the employees complained of performance ; lack of strategic height of human resource management, performance appraisal that can not be linked with the actual situation. The following analysis of several performance evaluation methods and its influence is from the perspective of human resources. Each has its advantages and disadvantages, and also has different emphases. I want to share it with everyone and hope everyone can learn something from it.展开更多
