防破拆设备安全性与可拆解性的冲突量化研究

为保证安全性,保险柜、防盗门、银行自动柜员机(automated teller machine, ATM)等设备均进行防破拆设计,在提高安全性的同时,减弱了自身可拆解性,降低了其回收利用价值。文章以拆解工具和拆解时间为指标,依据相关规范对常规破拆工具进行等级划分,分别在非法拆解和回收拆解下测得拆解时间。采用层次分析法(analytic hierarchy process, AHP)分析拆解工具和时间的指标权重,提出量化公式来评价防破拆设备的安全性和可拆解性,并以安全性、可拆解性和指标权重建立冲突量化评价公式,对冲突实现了量化处理。基于ATM保险柜门实物结构,对全钢制结构和水泥夹层结构方案进行冲突量化对比分析,结果表明,水泥夹层外壳的防破拆设计冲突较小,为新品设计提供了方向。

The anti-dismantling design of safety deposit box, security door, and automated teller machine (ATM) have been carried out for security. However, while improving the security, the dismant-lability of the equipment will be weakened and the recycling value will be reduced. Considering the dismantling tools and time, the conventional dismantling tools were graded according to the relevant standards; the dismantling time was measured using illegal dismantling modes and recycling dismant-ling modes. The weight index of dismantling tools and time was analyzed based on analytic hierarchy process (AHP). The quantitative formula was proposed for evaluating the performance of the security and the dismantlability of the equipment. The quantitative formula based on dismantling tools and dis-mantling time was proposed for evaluating the conflict between security and dismantlability, so as to complete the quantification of conflict. Furthermore, considering the ATM safe door, the conflict of two structures, i.e. steel plate and steel-cement-steel, was quantified. The results show that the anti-dismantling design of the structure of steel-cement-steel has less conflict, which provides a direction for new product design.
