Many individuals nowadays find it difficult to envision their lives without computer systems. This circumstance demonstrates how crucial a functioning laptop plays in society because using laptops to "search and save data, create tables and graphs, edit images, music, video, and perform other tasks" makes people's lives simpler and more pleasant. The aggregate functionality of an informational system can be significantly impacted by the computer infrastructure. Choosing equipment with the right qualities without increasing expenses is a significant and difficult decision. This issue becomes prominent when selecting laptops and desktops, as a greater proportion of assessment criteria should be considered. In a "Multi-criteria decision-making (MCDM)" situation, the most preferred laptop needs to be selected from a range of available options. The laptop selection problem is analyzed in this study using strategies focused on "the Grey Relational Analysis (GRA) method." The rankings for the laptops are as follows: HP 17- ck1023TX is ranked 1, ASUS ROG Zephyrus M16 (2022) is ranked 2, MSI Raider GE78HX 13VH-088IN is ranked 3, ASUS ROG Strix SCAR 16 (2023) is ranked 4, Dell Alienware x17 R2 is ranked 5, HP ENVY 15-ep1087TX is ranked 6, ASUS ROG Zephyrus M16 is ranked 7, Acer Predator Helios 300 is ranked 8, and ALIENWARE m15R3 is ranked 9. The ranking order is as follows: "HP 17-ck1023TX > ASUS ROG Zephyrus M16 (2022) > MSI Raider GE78HX 13VH-088IN > ASUS ROG Strix SCAR 16 (2023) > Dell Alienware x17 R2 > HP ENVY 15-ep1087TX > ASUS ROG Zephyrus M16 > Acer Predator Helios 300 > ALIENWARE m15R3." According to the "Grey Relational Analysis (GRA) technique" used in this study, "HP 17-ck1023TX, ASUS ROG Zephyrus M16 (2022), and MSI Raider GE78HX 13VH-088IN" are the three most preferred laptops in recent times. The capacity of the SSD, RAM, graphics quality, and price of the laptop had a dominant effect on customers' preference when selecting the product.

INTRODUCTION Year after year, more people are using computers due to technical advancements. Meanwhile, new features and models for computers are continually being developed. Three basic categories can be used to assess computers: tablets, laptops, and desktop PCs [1]. Sales of desktop and personal computers have been declining, while sales of laptops and tablets have experienced temporary decreases followed by surges. It is evident how commonplace computer sales are when one considers that the average lifespan of a computer is five years. Every year, a commodity with such strong market demand introduces new qualities that require judgment to act upon. Due to the availability of various brands, models, and integrated features [2,3], this screening process is challenging. Nowadays, many individuals find it impossible to imagine their lives without computers. This circumstance demonstrates the crucial role that computers play in our daily lives, as they simplify and enhance tasks such as data search and storage, table and diagram creation, and image, audio, and video editing, among other things [4]. Individuals can communicate with millions of people around the world simultaneously, regardless of their location. The sizes and casings of individual computers are typically used for classification. One such type is the laptop, which is more popular due to its versatility, portability, and mobility. There are several laptops available on the market from various manufacturers, each with different capabilities [5]. However, they often resemble one another, making the selection of a functional laptop that meets the buyer's needs both crucial and challenging. In many technical, business, and other challenges, competing goals must be simultaneously
