A system dynamics based model for medical equipment maintenance procedure planning in developing countries

摘要: Clinical Engineering (CE) department activities include acquisition, maintenance of medical instrumentation, health technology assessment, informatics, and risk management. In this work the authors focus on in developing countries where there is a lack acquisition planning, budgeting critical equipment breakdown. past decade has been an explosion use system dynamics modeling healthcare. paper based model for designed; it incorporates 8 key variables that influence progress maintenance. This shows effect changing variable others. intended to maximize quality minimize cost time developed causal loop diagram, which cause diagram. iThink software used development model, together with vensim The results show are defect rate, breakdown cost. conclusion determines decision acquiring new equipment. type number be acquired determined according available budget.
