There was a need for the development of an innovative production system for the Fusion prototype stretcher at Stryker Medical. As an extension of the existing production system, time studies were conducted on the current line in order to obtain valuable information about the new and old product and process. Through the use of facilities design, predetermined time systems, simulation, line balancing, statistical analyses, and personal experience with the prototype, an original production system was developed. This production system strives for efficient utilization of floor space, improved material flow, a balanced production line and distribution of work, as well as optimal efficiency at a reduced operational cost. Line balancing tables, precedence diagrams, and AutoCAD layouts were developed. In addition, an ergonomic assessment was conducted on the current system to ensure that a safe and suitable work environment could be developed for line workers.
Five different scenarios were developed using ProModel simulation software for the Fusion stretcher line. From these scenarios it was determined that Stryker will be able to produce well above the projected demand of 4 stretchers per day with only two employees. The ergonomic assessment that was conducted suggests that the current and proposed work environments are suitable because of the low to medium risk score. To accommodate workers, suitable fixtures and tooling will be needed to prevent injuries that could lead to muscular skeletal disorders.
