Demonstration and evaluation model of key instrument procurement in blood collection and supply institutions: based on fuzzy evaluation method

Abstract

Objective To establish the indicator and fuzzy evaluation model for the procurement demonstration of key instruments and equipment, in order to provide a scientific and reliable method for the procurement demonstration of equipment in blood centers. Methods Through literature review and Delphi method, the procurement evaluation indexes of key instruments and equipment in blood centers were established. The weights of each index were calculated using analytic hierarchy process (AHP) by sending questionnaires to experts. According to the established indicator and fuzzy comprehensive evaluation method, a scoring model of procurement demonstration of key instruments and equipment was constructed. The blood screening total laboratory automation was analyzed and verified using the established demonstration model. Results A total of 4 first-level evaluation indicators and 16 second-level evaluation indicators were established. The weights of urgency, social benefit, economic benefit and technical condition were 0.496, 0.300, 0.051 and 0.153, respectively. For the blood screening assembly line system to be procured, the evaluation value was 0.629, and it passed the procurement demonstration. Conclusion The quantitative and scientific evaluation of the procurement evaluation can be carried out by establishing the evaluation index and fuzzy comprehensive evaluation method for the key instruments and equipment of blood centers.
