This comparative research study explores the efficacy of two parallel systems, Model A employing a hot standby configuration and Model B utilizing a cold standby setup, each comprising three units operating based on demand. The investigation focuses on evaluating the reliability and cost-effectiveness of these systems, employing metrics such as Mean Time to System Failure, availability at full and reduced capacity, repairer busy periods, downtime, and profit analysis using Semi-Markov and regenerative point techniques. Results reveal that Model B (cold standby) outperforms Model A (hot standby) across multiple parameters, including Mean Time to System Failure, availability, repairer busy periods, downtime, and profitability. Specifically, Model B demonstrates higher values for Mean Time to System Failure, Availability at full and reduced capacity, Busy period for repairmen, and Profit in Rs. Consequently, it is inferred that Model B proves to be more reliable and efficient than Model A. These findings underscore the potential advantages of employing cold standby configurations in similar machinery setups, offering insights to enhance system performance and minimize downtime, thus suggesting avenues for optimizing cold standby parallel systems based on the study's outcomes.

“…The air interface of 5G should be a wireless channel with multiple standards and unified standards, which can solve all contemporary access problems and flexibly adapt to various mobile services. Therefore, the traditional network functions of mobile communication systems no longer exist 6 . The first three mature technologies (such as subcarrier orthogonality, access cyclic prefix, and proper spatial distance) ensure multiuser and multiaccess 7–9 .…”

Summary With the changes of the times and the rapid development of the mobile Internet and the Internet of Things, network communications are facing increasingly severe challenges. Due to the user exclusivity of the orthogonal resources of the existing orthogonal multiple access technology, it is difficult for the number of accessible users and the spectral efficiency to meet the application requirements of network communications. 5G technology will meet the diverse business needs of people in various scenarios such as life, work, leisure, and transportation. This paper analyzes the 5G‐oriented non‐orthogonal multiple access (NOMA) technology and designs and implements a NOMA technology simulation platform laboratory based on 5G technology. The entire simulation experiment adopts a modular design concept so that it can be modified and extended in the future network communication. In this paper, the user pairing scheme and power allocation algorithm of NOMA technology are studied in depth. For the user pairing scheme, this paper adopts two schemes: traversal search pairing scheme and grouping pairing scheme. For the same algorithm for power allocation, this paper studies two suboptimal power allocation algorithms including fixed power allocation and partial transmission power allocation. Simulation experiments show that the average cell throughput and cell edge user throughput of NOMA are slightly lower than when the traversal search pairing scheme is adopted: the average cell throughput has decreased by approximately 4%, and the cell edge user throughput has decreased by approximately 1.6%. The packet pairing scheme is a compromise between complexity and throughput performance. For different power allocation factor values, the overall throughput performance of some transmission power allocation algorithms is better than the flower pollination algorithm (FPA).

“…Ding and Lisnianski (2008) considered performance rates and corresponding state probabilities of MSS incorporating fuzzy values. Further, in order to develop a complex system, some researchers (Nagiya and Ram, 2013; Ram and Nagiya, 2016) provided methods to evaluate reliability characteristics and performance of satellite communication system and mobile communication system respectively. Ram (2013) gave a survey on system reliability approaches.…”

Purpose The purpose of this paper is to evaluate the reliability indices such as reliability, mean time to failure and sensitivity analysis. Design/methodology/approach A non-repairable multi-state complex system with two subsystems, namely, S1 and S2, is studied. The subsystems S1 and S2 are multi-state weighted r-out-of-n: G and s-out-of-m: G systems, respectively. Every component of the sub-system S1 consists of linear (f, l, k): G system, and the sub-system S2 consists of circular (f, l, k): G system. The subsystems are connected in series arrangement and components of these subsystems are arranged in parallel. Findings Markov stochastic process has been applied to obtain probability of components of the subsystems and various results discuss such as reliability, mean time to failure and sensitivity analysis with the help of the universal generating function. Originality/value In this work, reliability measures of the purpose system can be enhanced under the high profit.
