An innovative approach to the study of the model of a medical institution

The majority of municipal medical institutions are not working effectively enough. Long waiting in the queue to see a doctor is one of the most significant problem of the organization in the field of healthcare. The SADT (Structured Analysis and Design Technique) methodology was used to find out the problems of functioning of the medical center. Functional diagrams of the subject area were constructed, which helped to understand how individual business processes of the organization that need to be optimized are implemented. A simulation model of the medical center "Detstvo+" in the GPSS World programming language has been developed. it is an open Queuing network consisting of 5 large nodes that are Queuing systems, which allows us to imagine the process of functioning of the medical center. The model was optimized according to the efficiency criterion of this system: while maintaining the volume of the incoming flow of applications, the number of rejections is kept to a minimum, while it is necessary to reduce the length of queues for doctor appointments. This model can also be used by institutions with a similar organizational structure to improve their systems and make management decisions.

Effect of Buffer Size Variation on Remanufacturing Environment

A remanufacturing is an independent institution in which a variety of activities such as disassembly, inspection, disposing, refurbishing, repairing, remanufacturing, transportation and reassembly are performed. We propose an approach that uses an open queuing network, decomposition principle and expansion methodology to analyze the remanufacturing system and use Taguchi method to find out how much the buffer sizes affect on performance. The objective function values, throughput and total cost, are calculated for each experiment. Main effects plots show how each factor affects the response characteristic.
