The multicriteria decision-making methodology is utilized to assess different portable hard disk drive alternatives, according to the purchaser/retailer/wholesaler liking with respect to various attributes. The hard disk drive comes under various types and has a number of attributes connected with it such as storage capacity, size, data transfer speed and physical dimensions. The modern market caters to a wide variety of customer needs. Therefore, it becomes the need of the hour to present a simple technique to select the best alternative for purchaser/retailer/wholesaler to satisfy their combined needs. Among the multicriteria decision-making methods, the more simple and widely used technique weighted aggregated sum product assessment is utilized in this work. The data of different hard disk drives were collected that were available in the Indian market and 24 different models of five brands were considered in decision-making. The equal weights method and objective weights method, that is standard deviation method, are utilized to allocate weights of significance to the criteria. The ranks obtained with simple additive weighting, weighted product method and weighted aggregated sum product assessment are presented, and final ranks are considered with weighted aggregated sum product assessment method because it is an amalgamation of the simple additive weighting and weighted product method. The result reveals that Western Digital comes out to be the first choice as a brand because the top three models belong to them with both equal and objective weights. While utilizing these techniques, a consumer can purchase the best hard disk drive and it is also very advantageous for merchants and sellers to aid users in procuring their gadgets while manufacture of hard disk drive can produce their product with unique technological features aimed at particular users. Furthermore, the subjective weights can be considered to select the best alternative.

基于加权聚合总和产品评估法的便携式硬盘驱动器选择：以印度市场为例

根据购买者/零售商/批发商对各种属性的喜好，使用多标准决策方法来评估不同的便携式硬盘驱动器替代品。硬盘驱动器有多种类型，并具有许多与之相关的属性，例如存储容量、大小、数据传输速度和物理尺寸。现代市场迎合了广泛的客户需求。因此，现在需要展示一种简单的技术来为购买者/零售商/批发商选择最佳替代品以满足他们的综合需求。在多标准决策方法中，这项工作使用了更简单和广泛使用的加权聚合总和产品评估技术。收集了印度市场上可用的不同硬盘驱动器的数据，并在决策中考虑了五个品牌的 24 种不同型号。等权重法和客观权重法，即标准差法，用于为标准分配显着性权重。给出了简单相加加权法、加权乘积法和加权总和乘积评估法获得的排名，最终排名采用加权总和乘积评估法，因为它是简单相加加权法和加权乘积法的合并。结果显示，西部数据之所以成为首选品牌，是因为前三款机型均属于它们，权重相等且客观。在利用这些技术的同时，消费者可以买到最好的硬盘驱动器，对于商家和销售商来说，帮助用户购买他们的小工具也是非常有利的，而硬盘驱动器的制造可以针对特定用户生产具有独特技术特征的产品。此外，可以考虑主观权重来选择最佳替代方案。
