Abstract:
This paper provides a new sight of dynamic data envelopment analysis (DDEA) In dependence of investment activities or link factors. However dynamic DEA proposed by F¨are and Grosskpf regards the connectivity between two assessment periods , some link factors that bear consecutiveness between two assessment periods (namely, link factors) have not been noted. Then in this paper we aim to clarifythose link factors in details and based on them, we develop a new DDEA framework. To do this all factors that may affect on a DMU’s process in anassessment period are studied. These factors may be from another assessment period, i.e. be carry-over.Then based on these factors, a new DDEA framework is developed and then the important concept of efficiency measure of DMUs is developed in this new DDEA framework
