Analysis of intensive support equipment based on cost-efficiency

Because of the phenomenon that various support equipment reduce the security system deployment and economy, this paper analyzed the cost and efficiency of intensive security equipment that made by some similar function equipment. The measurement costs were taken into account in the cost model. To sort out the parameter values of the initial support devices, make them dimensionless, and select parameters that they are cost-related and do not have multiple collinearity. The remaining parameters were used to construct the life cycle cost estimation model of support device. In terms of efficiency, the calculation methods of the utilization rate and the satisfaction rate were given, and allocative efficiency is taken as the evaluation index. The cost-efficiency model is established to determine whether the intensification is feasible. Finally, an example is given to compare the equipment cost-efficiency ratio between initial support devices and intensive security equipment so as to evaluate whether the intensive support equipment can reduce the support scale and improve the economy after meeting the demand of security.
