In the current paper, we propose new models of inverse DEA problems when input prices are available. We consider not only the technical and cost efficiency simultaneously but also the income level of production units. In comparison with the existing model including basic inverse and cost-revenue based models, we have more flexibility in terms of determining simultaneously input and output levels in our models. We utilise proposed models for the efficiency analysis and further post input-output and planning study of hospitals in Mashhad, Iran. Primary results show the need for equipment, namely, active bed in the expansion planning.","PeriodicalId":38619,"journal":{"name":"International Journal of Mathematics in Operational Research","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136079150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
