Abstract
The paper presents a novel approach to real-time performance evaluation and prediction of mobile devices using an advanced methodological framework. This framework integrates the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) with entropy weighting and time series modeling to achieve highly precise performance status identification and adjustment strategies. By applying principal component analysis (PCA) for dimensionality reduction and feature engineering, the study constructs device performance profiles that gauge real-time operational conditions. The approach facilitates not only immediate performance assessment but also reliable long-term performance forecasting, significantly enhancing user experience and business value.
Introduction
The advent of highly industrialized and automated systems underscores the necessity of precise real-time device performance monitoring, particularly in mobile devices. Operational efficiency and reliability of these devices are influenced by computational resources, battery life, environmental conditions, and network parameters. Traditional evaluation methods fall short due to their uniform treatment of devices within the same model, overlooking individual performance degradation.
This paper introduces a sophisticated real-time perception model grounded in performance indicators, emphasizing the use of dimensionality reduction techniques for accurate evaluation. The framework developed meticulously assesses performance dynamics to aid production adjustments and optimize user experience. The methodology encompasses feature extraction processes, multi-level evaluation models with objective weighting, and time-series prediction models to monitor device health and performance trends effectively.

Methodology
TOPSIS and Entropy-Based Multi-Level Evaluation
The study leverages TOPSIS for ideal solution proximity ranking, employing normalization and distance calculations to derive comprehensive performance assessment scores without dimensional bias.
A key innovation is the application of entropy weight methods, quantifying feature influence based on distribution variability to objectively determine their impact within evaluation models, fostering precise real-time device performance assessments.
Hull Moving Average (HMA) for Smoothing
Given the high volatility of short-term device data, the Hull Moving Average algorithm offers superior smoothing capabilities by reducing lag and increasing sensitivity, crucial for attaining accurate performance state perceptions.
