“…In this kind of operation, there has been much development with regard to some aspects of maintenance effectiveness, which manifests itself as a critical analysis in order to optimally identify and correct the effects of equipment degradation. Therefore, using this methodology also contributes to operational safety and the prevention of accidents (Scott et al, 1992;Ashar and Bagchi, 1999;Jerng et al, 2011;Contri et al, 2012) Finally, one last issue to consider regarding the literature on Maintenance Effectiveness is the current trend of constructing, enhancing and applying new tools and technologies so as to optimize maintenance. One of the main developments in this matter is the incorporation of Information and Computation Technologies for the sake of maintenance effectiveness.…”

Increasing human dependence on engineering systems has recently made maintenance a higher priority. Thus, it becomes essential to study the many developments in this field, paying attention to some proposed models that do not appear to be effective in real applications. In this paper, we present a literature review on "maintenance effectiveness", here defined as the level to which a maintenance policy fulfills its pre-defined objectives or optimizes general maintenance actions, hence improving the productive activities of an organization. Some insights into the research so far developed -such as the relationship between interest in studying maintenance effectiveness in a sector and the severity of catastrophic failures in that sector -and possible future trends -such as the focus on case studies rather than more theoretical papers -are presented. We also found that there are still gaps in the literature that, if explored, will open new routes in potentially promising directions.

“…If the new position of the worst frog is better than its previous position after (1) and (2) are calculated, then it replaces the position of the worst frog and the worst position is recalculated. Otherwise, substitute for and repeat the worst position of the frog updating calculations in (3) and (2). If the frog in the worst position still cannot obtain a better position, then a frog with a new position is stochastically produced to replace the frog in the worst position .…”

“…It includes inspection, testing, diagnosis, disassembly, assembly, cleaning, repair, and replacement. Key equipment of radioactive installation that provides base functions must be maintained during installation lifetime [1][2][3]. In radioactive installation, most maintenance activities are conducted in a radioactive environment that is unsuitable for humans; in such cases, remote handling maintenance (RHM) is necessary [4].…”

Assembly sequence planning (ASP) of remote handling maintenance in radioactive environment is a combinatorial optimization problem. This study proposes an improved shuffled frog leaping algorithm (SFLA) for the combinatorial optimization problem of ASP. An ASP experiment is conducted to verify the feasibility and stability of the improved SFLA. Simultaneously, the improved SFLA is compared with SFLA, genetic algorithm, particle swarm optimization, and adaptive mutation particle swarm optimization in terms of efficiency and capability of locating the best global assembly sequence. Experiment results show that the proposed algorithm exhibits outstanding performance in solving the ASP problem. The application of the proposed algorithm should increase the level of ASP in a radioactive environment.

Remote handling maintenance (RHM) is the act of monitoring and maintaining equipment in a safety zone away from the site by applying a manipulator (robot) or special equipment inside the nuclear device to reduce the exposure dose and labor intensity for personnel. RHM technology is an important and indispensable tool for maintaining radioactive parts for large-scale scientific facilities. Bolt assemble/disassemble is an operation of RHM. This paper research on bolt assemble/disassemble operation in hot cell RHM to get some the proposals for bolt design and auxiliary tooling development in RHM. Four comparing experiments including the ball hexagonal head and hexagonal head, different length of clamping handle of pneumatic wrench, with block leg and without block leg, the rigid handle and the flexible handle were conducted. Significant conclusions were obtained for bolts disassembling and reassembling, which provide a basis for auxiliary tooling development for RHM.
