ObjectiveTo develop a method for constructing a modularized support system of medical supplies for military operations other than war (MOOTW) and to evaluate its feasibility. MethodsThe existing disease/injury spectrum and the consumption information of medical supplies in MOOTW were collected. The medical supplies demand in MOOTW was divided into general demand, special demand, and supplement demand according to the principles of modularity, systems analysis, logical analysis and cluster analysis. And a modularized support system for medical supplies was subsequently designed. ResultsIn accordance with the medical support missions and the analysis of loss due to noneffective, we constructed a modularized support system of medical supplies, which consisting of 32 basic modules in 4 categories. The catalogues of medical supplies for 7 common MOOTW missions were proposed based on the analysis of the consumption rules of medical supplies in MOOTW. The decision-making system for modularized support of medical supplies in MOOTW was designed in line with actual requirement of medical supply support in MOOTW. ConclusionSimulating test has demonstrated that the proposed decision-making system for modularized support of medical supplies in MOOTW can improve the flexibility, adaptability, and reliability of medical supply, and it is a new approach to implement precise medical supply support.
