Background and Objectives: Hospital bed utilization is influenced by various factors, which may be categorized into patient-related, physician-related, and administration-related issues. It could be argued that the causes of inappropriate hospital bed utilization would be perceived differently by the clinicians and the patients. Given the unique role of clinical practitioners in quality of car...

This paper presents a novel, multi-objective mixed-integer nonlinear programming (MINLP) model for a cell formation problem (CFP) with alternative means. Due to existing contradiction among objectives, three are considered: 1) Minimizing the total cost consisting of; intercellular movements, purchasing, operation, and maintenance; 2) maximizing the utilization of machines in the system; 3) mini...

in order to implement the cellular manufacturing system in practice, some essential factors should be taken into account. in this paper, a new mathematical model for cellular manufacturing system considering different production factors including alternative process routings and machine reliability with stochastic arrival and service times in a dynamic environment is proposed. also because of t...

hospital information system (his) should ideally allow different forms of data to be stored and used for decision making by clinicians and managers alike. this system has been developed since the early 1980's, and many hospitals gradually converted from an unrelated system into an integrated one. in successful implementation of his plans, the role of human factors, either individually or as a g...

This paper deals with the service performance analysis and improvement using discrete event simulation has been used. The simulation of the health care has been done by arena master development 14-version software. The performance measurement for this study are patients output, service rate, service efficiency and it is directly related to waiting time of patients in each service station, work ...

The use of renewable energy sources is often suggested to be a good solution for climate change and the dependency to fossil fuel. Biogas utilization is a one of these promising options that can mitigate these problems since biogas is produced by the fermentation of waste, so is rich in methane and has the same characteristics as natural gas. Biogas has increasingly been noticed in different co...
