Computer Simulation of Patient Flow in Obstetrical-Gynecology Clinics

Article Abstract:

Management's plan to combine two clinics is analyzed by computer simulation based upon present patient flow data and specific planned operational changes. The specific areas examined or tested are provider staff size-ratio, effect of new provider type, facility size-composition requirement, patient scheduling methodology, personnel utilization, staff arrival-departure effects, patient waiting time, and direct labor unit costs. Procedure duration and patient arrival time are gathered using log sheets for 2,000 patients; direct observation supplements logged data loss. The simulation system is GPSS. Model results contribute substantially to all eight target areas. The planned combining of the two clinics is postponed until adequate space is available. (Reprinted by Permission of Publisher.)

The Use of Admissions Simulation to Stabilize Ancillary Workloads

Article Abstract:

As part of the planning of a new hospital, an analysis was performed to determine the number of procedures that would be performed in each of nineteen ancillary departments on a day of the week basis. Because the planned occupancy was not the maximum possible, attempts were made using simulation to smooth the daily ancillary loads by varying the admission day of elective, urgent inpatient and outpatient loads. The methodology, sample outputs, and main conclusions are presented. (Reprinted by Permission of Publisher.)

Simulation of Speech Intonation by Legendre Orthogonal Polynomials

Article Abstract:

A method of fitting and synthesizing speech intonation by means of legendre orthogonal polynomials has been proposed and simulated. When applied to pitch curves and intensity curves, the fitting error was small. Using the fitting coefficients, the intonation of different types of spoken Chinese sentences was synthesized satisfactorily. Diagrams of intonation curves, graphs illustrating pitch channel performance, and a block diagram of intonation synthesis are included.
