An Evaluation of System Efficiency of the Enterprises’ Logistics System Based on DEA
Abstract: The research of the logistics is a crisscross and comprehensive analysis of multilateral subjects,which is of strong attribution of systemility、quantitality and optimality,especially in the rational analysis and evaluation of comparative efficiency of the logistics system.Operations Research(OR) is just a subject which focuses on the attribution of systemility、quantitality and optimality.Thus ,here,OR takes a very important position.It's mentionable that the application of OR including its models and methods is often different with those classical models because of certain especial attribution of the logistics system,as should be noteworthy here.In this paper,a new field of OR ―― Date Envelopment Analysis ( DEA ) is recommended.DEA is usually used to evaluate the comparative efficiency of units in some parallel departments or denominations.In this paper it analyzes the characteristics of the enterprises’ logistics and identifies the factor scheme used for the evaluation of its efficiency. A model based on data envelopment analysis is used to evaluate the systems’ efficiency. It calculates the total efficiency、technological efficiency、 scale efficiency of all DMUs and their scale efficiency return situations.Some feasible ways for ineffective DMUs to make them effective is put forth. It also analyzes the relationship between system efficiency and resources utilization rate. Some useful advice on the development of the enterprises’ logistics system is achieved,which is valuable to make decision for some sections.
Key words: data envelopment analysis; logistics; evaluation; scale efficiency; resources utilization rate.
