ABSTRACT

Traditionally, the managers in a distribution center (DC) roughly evaluate the performance

variations via the traditional decision support information (i.e., broken-line graphs of the

employee performance) to determine whether an employee should be rewarded or trained.

Since the performance variations of employees might include some involuntary performance

variations, the employee performance trend might not be accurately identified if the DC

managers rely only on the traditional decision support information. In order to provide

improved decision support information without involuntary performance variations, this

study develops an integrated model for employee performance estimation and trend analysis

which includes the shop-floor data processing, performance trend analysis and trend index

visualization modules. The proposed model can be used to estimate the employee

performance and analyze the performance trend under the condition that the external

variations have been removed. Based on the proposed model, this study also establishes a

web-based system to generate the performance trend analysis diagram. According to the

diagram, the DC managers can efficiently and easily acquire the employee performance

trend at a specific time interval and for a long time. A real-word case was used to evaluate

applicability of the proposed model and platform. Furthermore, the effect of the external

variations and the advantages of the performance trend analysis diagram were investigated.

As a whole, by using the proposed model, the DC manager can comprehensively identify

whether an employee should be rewarded or trained based on the traditional and improved

decision support information.
