Executive Summary : | This study aims to improve service continuity in retrial queueing systems by integrating standby servers and preventive maintenance strategies. The research will provide empirical evidence of the benefits and feasibility of these strategies, guiding decision-making for system designers and operators. The methodology involves a systematic approach to analyze and enhance service delivery through the integration of standby servers and maintenance strategies. The study will focus on real-world case studies in industries such as manufacturing and network management, demonstrating the practicality and effectiveness of the proposed approach. The findings will be used to guide decision-making for system designers and operators, ensuring the proposed strategies are both theoretically effective and practically viable. The study will also explore the potential applications of these strategies in industries such as manufacturing, telecommunications, and critical infrastructure. The hypothesis is that the integration of standby server mechanisms and optimized preventive maintenance schedules will lead to a significant increase in overall system reliability and availability, resulting in reduced downtime and improved service performance. |
