Considerable attention has been given to load adjustment and mission abort strategies, aimed at striking a balance between advancing success mitigating system failure risk. Existing studies predominantly center on optimizing loading policies without factoring in potential constraints governing decisions. In practice, however, there are instances where aborting the is not viable during specific stages. For example, submarines may be prohibited from missions surfacing for rescue operations due confidentiality reasons. This paper investigates joint optimization of condition-based dynamic while considering limitations missions. Specifically, dynamically modified based progress condition, terminated permissible stages ensure safety. An example an integrated minesweeper vehicle used illustrate proposed model obtained results.

This paper proposes an integrated framework for maintenance, spare parts ordering, and quality control planning within a multi-state production system that is subject to two competing modes of failure: hard failure soft failure. Hard failures occur suddenly without any prior warning, whereas develop following the onset defect. The product significantly influenced by state system, as defective typically leads increase in non-conforming products. To address this, periodic inspections are conducted detect defects early, preventive replacements (PR) scheduled upon identification state, which acts crucial indicator. Corrective (CR) become necessary when either or occurs. timeliness these contingent part availability; thus, we implement hybrid ordering policy enhance responsiveness. PR CR executed promptly time-based ordered spares accessible, while condition-based order triggered event shortages orders. determine optimal inspection interval point, analyze renewal scenarios with objective minimizing expected cost rate. We propose optimization algorithm simulation procedure validate effectiveness our through numerical experiments. results highlight significant potential approach reducing unit losses related products effectively
