Description

产品使用质量或性能的判定方法及设备 技术领域
本发明涉及产品性能判定技术领域,特别是涉及产品使用质量或性能的判定方法及设备,即产品在使用过程中可能会对用户安全和健康等方面产生影响的产品使用性能是否合格的判定方法及设备。
背景技术
现有的认证技术规范中对产品是否满足某一标准要求通常采用符合性判定方法,即某一检测结果是否在某一个值或者某一区间范围内。
该方法的弊端在于以下几个方面:
弊端1,生产制造技术不断更新,现有的产品性能测试及判定方法可能无法支持使有最新生产制造技术制造的产品,以往判定方法存在局限性,容易跟不上生产制造技术的发展;
弊端2,检测标准的时效性和适用性,如果检测标准落后于技术发展,新的生产制造技术突破了检测标准还能带来比较好的结果,就会影响认证结果的准确性,给企业和社会造成损失。
弊端3,判定标准的单一性。产品性能符合性能测试的判定标准比较单一,仅以单一数值为判定界限,需要对测量误差进行精准控制和计算,测量误差过大会很容易引起结果判定的偏颇,影响结论的客观公正性。
弊端4,判定方法的片面性和绝对性。性能方面的符合性测试主要针对产品固有属性是否满足特定的要求,而这个要求主要基于产品的物理性能,对目标用户是否适用尚不可知。使用传统方法不能准确判定产品使用质量或性能是否适用于其目标用户并满足目标用户的要求。目前,大部分产品的检测判定指标未经过实际使用人群的测试 验证,可能来源于已有的生产制造经验或者几个厂家之间的协商一致。

附图说明
图1为本发明一个实施例中产品使用质量或性能判定方法的步骤流程示意图。
图2为本发明一个实施例中提供的电子设备的实体结构示意图。
具体实施方式
下面结合附图和实施例,对本发明的具体实施方式作进一步详细描述。以下实例用于说明本发明,但不用来限制本发明的范围。
为了对弥补标准判定存在的各种问题,本发明给出了一种产品使用质量或性能的判定方法及相应设备。
一种产品使用质量或性能的判定方法,如图1所示,包括:获取使用前测试数据和使用后测试数据,计算体验因子效应量;对所述使用前测试数据和使用后测试数据进行方差分析或t检验,获得体验因子在规定置信水平的显著性水平p值;将所述体验因子显著性水平p值与显著性水平α值进行比较并结合体验因子效应量得出差异显著性结果。
在本技术方案中,获取使用前测试数据和使用后测试数据,可以有效得到产品使用前后的真实数据,通过方差分析或t检验,对比得到使用前后的差异性,求取体验因子显著值,并将其与显著性水平进行比较,由此判断用户使用产品的影响效果,将该影响效果与常规的标准判定结果相结合,能更加准确判定产品使用质量或性能,解决单一标准判定产生的各种局限性问题。比如,针对生产制造技术不断更 新,现有性能测试方法无法准确判定该产品是否满足用户使用质量或性能要求的问题,通过本技术方案采集用户使用前后的数据,通过对比用户使用前后的实际数据情况,获取产品使用质量或性能是否合格,如果合格,可以辅助标准检测;如果不合格,可以建议产品性能检测采用更先进设备,提出更高的要求而避免被误判。又比如:针对检测标准时效性问题,通过本技术方案的判断,可以验证现有产品使用质量或性能标准要求是否具备足够先进性,同时能促进标准的更替。又比如:对判断标准单一,结果不公正的问题,本技术方案给出用户使用产品前后的测试数据,并最终确认产品使用质量或性能是否良好,从而增加了产品使用质量或性能判断的另一个维度,提高了判断结论的公平、公正性。又比如:针对判定方法的绝对性,缺乏用户真实使用情况的判断依据,本技术方案的测试数据来源于用户真实使用的测试数据,更贴近使用场景,在判定方法中增加了用户使用效果或影响的结论,为产品推向市场后的使用效果提供更准确的判断依据。
该产品使用质量或性能的判定方法,可以通过如下步骤展开,如图1所示:
首先,根据置信水平及统计检验力等确定样本量;
一个实施例中给出样本量的计算公式:N=Z2×(P×(1-P))/E,其中,Z为置信区间、n为样本容量、d为抽样误差范围、σ为标准差,一般取0.5。E:样本均值的标准差乘以z值,即总的误差p:目标总体占总体的比例。
通常置信水平为95%,由此确定样本量即可。在其他的实施例中,还可以根据实际测试目的和要求更换置信水平。
然后,获取样本量产生的所有使用前测试数据和使用后测试数据,计算体验因子效应量;
体验因子效应量即体验因子的效应量。效应量是指由于因素引起的差别,是衡量处理效应大小的指标。在本行业存在多种方法计算效 应量,比如采用Excel计算效应量。
以疲劳为例,关于疲劳的界定,可以参考现有对疲劳的判定方法,也可以根据经验值直接确定。另外,只要保证第一次测试和第二次测试之间存在足够的时间,在该时间内,使用者的使用状态发生变化,都可以理解为第一次测试为疲劳前测试,第二次测试为疲劳后测试。
需要说明的是,在本技术方案中,采集测试数据的步骤可以包括在整个判定方法中,也可以独立于本技术方案中的判定方法,在执行获取步骤时,可以直接读取已存储的数据。数据为选择目标用户后诱发任务获取的数据。对于诱发任务的设定方法为:诱发任务及其时间长短的设定可以依据现有的测评数据经验以及测评结果,也可以参考行业公认的测试内容和测试时间长短。诱发任务需获得行业公认或者具有实验数据依据。目标用户作为被试者,选择的方式为:通常建立专门的可追踪样本库,也可采用方便随机抽样进行选取。样本量的确定需要根据置信水平、检验力等并利用相关公式来进行计算,也可以根据以往实验经验来确定。
当采集测试数据包括在整个判定方法中时,由于使用者存在个体差异,这种差异将通过实验设计以及数据处理等处理方法来进行平衡或消除。
随后,将使用前测试数据和使用后测试数据进行单因素方差分析或t检验,获取体验因子显著性水平p值;
在其他的实施例中,也可以根据需要进行双因素方差分析或多因素方差分析或t检验。方差分析或t检验可采用现有程序直接计算。
然后,根据规定的置信水平和体验因子效应量,将体验因子(疲劳因子)显著性水平p值与显著性水平α值进行比较得出显著性结果。
显著性结果包括:不合格、合格和优异,在一些情况下合格和优异仅是程度的不同而已。
在进行比较时,需要考虑正向影响比较,还是负向影响比较。比 较和得出显著性结果的方法为:
如果被试者诱发任务后的总体测试结果明显比测试前差,则直接判定该产品不符合要求。具体判定标准如下:
(1)对于给使用者带来不良负向影响的检测判定
在保证产品使用质量或性能符合规定的客观要求的基础上,利用目标用户群体的使用体验来进行判定,通过使用前后的用户测试数据比较结果来进行产品使用质量或性能判定。
如果测试任务后,用户的测试后数据比测试前数据更高,且在一定置信水平(如95%,其他实施例中也可以设置为80%、90%或99%等)其数值显著高于测试前数据表现情况(p<0.05),则判定为不合格;
如果p>0.05,则说明测试前后状态没有发生大的变化,未给用户带来不良影响,则判定为合格;
如果诱发任务后,用户测试后数值比测试前数值更低,且在一定置信水平(如95%,也可以设置为80%、90%或99%等)其数值显著低于测试前数据值情况(p<0.05),说明该产品对用户具有显著更好的影响,则判定为优异。
(2)对于给用户带来正向影响的检测判定
在保证产品使用质量或性能符合规定的客观要求的基础上,利用目标用户群体的使用体验来进行判定,通过使用前后的用户测试数据比较结果来进行产品使用质量或性能判定。。
如果测试任务后,用户测试后数据数值比测试前数据数值更低,且在一定置信水平(如95%,也可以设置为80%、90%或99%等)内显著低于测试前的数据数值(p<0.05),则判定为不合格;
如果p>0.05,则说明前后状态没有发生质的变化,未给用户带来影响,则判定为一般,没有发生变化,未给用户带来价值,也可判定为不合格;
如果测试任务后的用户测试结果比测试前数据数值更高,且在一定置信水平(如95%,也可以设置为80%、90%或99%等)内显著高于测试前的数值(p<0.05),则说明该产品对用户具有好的影响,则判定为合格。
