Read the Chapter 9 Case Study "Facility Layout at Wheeled Coach Ambulance" and watch the video, then write a summary of at least 300 words using the accompanying discussion questions to guide your essay written in APA style, with a reference page and a cover page.https://www.mathxl.com/Student/MediaPopup.aspx?typ...Facility Layout at Wheeled CoachWhen President Bob Collins began his career at Wheeled Coach, theworld’s largest manufacturer of ambulances, there were only a handful ofemployees. Now the firm’s Florida plant has a workforce of 350. Thephysical plant has also expanded, with offices, R&D, final assembly,and wiring, cabinetry, and upholstery work cells in one large building.Growth has forced the painting work cell into a separate building,aluminum fabrication and body installation into another, inspection andshipping into a fourth, and warehousing into yet another. Like many growing companies, Wheeled Coach was not able to design itsfacility from scratch. And while management realizes thatmaterial-handling costs are a little higher than an ideal layout wouldprovide, Collins is pleased with the way the facility has evolved andemployees have adapted. The aluminum cutting work cell lies adjacent tobody fabrication, which, in turn, is located next to the body-installation work cell. And while the vehicle must be driven across astreet to one building for painting and then to another for finalassembly, at least the ambulance is on wheels. Collins is alsosatisfied with the flexibility shown in design of the work cells. Cellconstruction is quite modular and can accommodate changes in product mixand volume. Additionally, work cells are typically small and moveable,with many work benches and staging racks borne on wheels so that theycan be easily rearranged and products transported to the assembly line.Assembly-line balancing is one key problem facing Wheeled Coach andevery other repetitive manufacturer. Produced on a schedule calling forfour 10-hour work days per week, once an ambulance is on one of the sixfinal assembly lines, it must move forward each day to the nextworkstation. Balancing just enough workers and tasks at each of theseven workstations is a never-ending challenge. Too many workers end uprunning into each other; too few can’t finish an ambulance in 7 days.Constant shifting of design and mix and improved analysis has led tofrequent changes.Discussion Questions*1. Develop a layout model for Wheeled Coach. Include in your model eachstep in the process. Assigned the steps with predecessors. Use minutesas your time increment. Calculate a cycle time, theoretical time,balance the line using the longest task time rule and determine theefficiency from your simulated data. 2. What other analytical techniques are available to help a company like Wheeled Coach deal with layout problems?3. What suggestions would you make to Bob Collins about his layout?4. How would you measure the “efficiency” of this layout?
