Currently, the passive part of space station platform's docking device has been finalized, emphasizing need for a mechanism that enables on-orbit assembly large payloads using in-situ resources. This paper presents design compact, high-precision dual-component loads. First, we propose parametric active and sides, accompanied by constraint equations capture mechanism. Next, progressive positioning method, beginning with coarse correction followed fine correction, is proposed. The calibration performance are analyzed to initially deviations achieve high-accuracy electrical hydraulic connectors subsequently. Static analysis both single dual components reveals positive correlation between load-carrying capacity diameter. During prototype testing, maximum positional were measured 0.12 mm in X-direction, 0.5 Y-direction, 0.07 Z-direction. angular deviation was 0.04° when operated together. Finally, impact axial radial conditions orbit verify loading requirements satisfied. work offers theoretical technical insights future development mechanisms

Unreliable energy supply disrupts productivity and escalates costs in manufacturing enterprises, highlighting the need for robust resilience strategies. Existing multi-criteria decision-making (MCDM) methods, such as analytic hierarchy process (AHP), best–worst method (BWM), unaugmented TOPSIS, often lack advanced risk prioritization objective criteria weighting, limiting their effectiveness addressing complex, multidimensional challenges. This study proposes an integrated framework that combines Failure Mode Effects Analysis (FMEA) prioritization, CRITIC-method weighting based on 4A's dimensions—availability, accessibility, affordability, acceptability—and fuzzy-TOPSIS strategy ranking. The bridges theoretical rigor with operational applicability, unique challenges faced by enterprises. Validated through a real-world case sensitivity analysis, it identifies actionable strategies, flexible scheduling, demonstrating consistent rankings across comparative analyses fuzzy VIKOR, WASPAS, MARCOS. sector-specific approach advances both academic understanding industrial practice providing scalable, tool enhancing resilience. presents integrating FMEA, CRITIC-method, within to address It prioritizes risk, provides ranks strategies under uncertainty. study, effective demonstrates adaptability, confirming robustness via analyses.
