An effectiveness evaluation method for the mobility capability of a certain type of equipment is proposed to address the uncertainty and imprecision of evaluation indicators that affect the results. The subjective-objective weighting method， entropy weighting method， and cloud model are applied to comprehensively assess the mobility effectiveness of the equipment. An evaluation model for mobility effectiveness is developed， and the basic steps of the evaluation process are discussed. The evaluation results are expressed in the form of a cloud-based membership function. The method provides an intuitive evaluation of the equipment’s mobility effectiveness. Case study results demonstrate that this method can effectively assess the mobility efficiency of the equipment and support decision-making in mobility planning.
