Blades R Us is a growing manufacturing firm that produces high-pressure turbine blades. The company supplies these to airline companies as replacement parts for use in large commercial jet engines. The high-pressure turbine is the segment of the engine that undergoes the most stress and heat. This requires that these parts be replaced frequently, so Blades R Us operates a relatively large firm with constant demand for its products. It operates out of Philadelphia, Pennsylvania, with a workforce of approximately 1,000 employees. Its annual output is based on demand, yet at fill capacity, it has the ability to produce 100,000 blades a year. The company’s largest suppliers are casting houses, which take a rough shape of the final product to very demanding specifications given by Blades. Blades R Us then does the final detail work to bring it to Federal Aviation Administration regulations.
