“…Total Productive Maintenance plays an essential role in Japanese philosophy, representing a concept in the field of maintenance and equipment management aimed at achieving the highest possible level of efficiency and production quality through optimal maintenance and management of production systems [28]. The main goal of TPM is: zero failures, zero defects, zero accidents [29].…”

Assessing the best set of maintenance guidelines for various types of failures is often a challenging and complex task. It requires understanding various factors such as safety aspects, environmental issues, energy savings, costs, budget constraints, system reliability, resource utilization, and more. Implementing the correct maintenance process is a critical step in production to increase reliability and improve the effectiveness and quality of the production system. Despite the significant importance of this issue, there are not many studies that analyse and develop procedures for selecting the optimal maintenance strategy. This paper presents the selection of the optimal maintenance strategy using multicriteria decision-making, specifically the Analytic Hierarchy Process (AHP), for a case study involving a company in the automotive industry. The defined alternatives are the four most commonly used machine maintenance strategies in the industry: corrective, preventive, condition- based maintenance, and total productive maintenance. The decision criteria considered in the analysis are: production quality, reliability, costs, and safety, along with their respective sub-criteria.

“…The extreme susceptibility of fully stabilized zirconia (FSZ) to thermal shock is a severe concern in electrochemical cells, which is resolved by using partially stabilized zirconia (PSZ) cells 9 . To utilize the potential of zirconia ceramics, its stabilization to retain the phase and enhanced properties due to transformation toughening many approaches to obtain stabilized zirconia powders have been researched 10 . Sol-gel 11 , spray pyrolysis 12 , precipitation routes 13 , and rapid combustion routes 14 are the most effective chemical techniques.…”

Cryo-milling was used to make calcia stabilized zirconia (CSZ) powders with 9 mol%, 12 mol%, and 15 mol% of calcia. Powder X-ray diffraction was done to examine the phase growth in prepared powders over the course of 80h of mechanical alloying (MA) in cryogenic environment at 300rpm. The calcined powders were hydraulically pressed into cylindrical shaped sensor elements in a uniaxial press and then sintered for 4h at 1400°C. The microstructure of sintered pellets were studied using Scanning Electron Microscope (SEM). Electrical Conductivity measurements of the prepared stabilized zirconia at various temperatures over a temperature range of 200°C to 500°C using a dualprobe impedance analyzer is carried out and the effects of composition and temperature on the grain boundary impedance of CSZ were analyzed. Conductivity is discussed in terms of ionic vacancies in the bulk due to calcium ion substitution and available grain boundary paths. Ionic Conductivity of prepared CSZ is compared for suitability in oxygen sensing applications.
