The problem is formulated as multi-objective mathematical program. The objectives driving the reallocation of beds could be conflicting in nature. The number of needed beds in each department is found to be highly related to length of stay (LOS) of a patient. Some described it as a random variable following a power law distribution. Hence, determining the number of the reallocated beds in each department could be treated stochastically because it depends on the fluctuation of the LOS. The complexity of the problem is taking care of by formulating the problem as multi-objective stochastic transportation problem and finding a compromise solution using a linear fuzzy function on the deterministic equivalent. The program is polynomial time solvable. The approach is illustrated through a bi-objective bed rearrangement problem, treating the possibility of increasing the admissions and the bed occupation, with real data from a hospital.</p>","PeriodicalId":45876,"journal":{"name":"Journal of Multi-Criteria Decision Analysis","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2020-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/mcda.1725","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44487329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HGDM is a decision-making problem with a large number of decision makers (DMs) or experts organized in a hierarchical structure. For this problem, a practical solution approach based on pairwise comparisons is developed. For evaluating the projects in organizations, specifically for the IT projects, a hierarchy of many DMs make project proposals and assess proposed projects using various sets of criteria. The proposed HGDM approach is applied to the evaluation and prioritization of IT projects. A problem with 22 DMs and experts in a three-level hierarchy, 29 criteria and 15 projects is solved using the proposed HGDM approach. The HGDM approach can deal with more complex real-life problems such as problems where more than 500 projects, 100 DMs and experts, and 100 criteria exist.

Occupational Health and Safety Assessment Series (OHSAS) 18,001:2007 is a good alternative to strengthen the implementation performance of the ISM Code. An integrated ISM-OHSAS safety system can potentially construct a more powerful and practical OHSMS by redesigning safety procedures in ships as a workplace.
