Buy Existing Paper - The Rotomoto Company


The Rotomoto Company is being faced with a challenge of deciding the best press machine it should purchase on the basis of purchase costs, customer specifications, and operational costs and which is to be used to produce small rotor motors. Based on the sales information that is available, two press machines are available in the market, both of which claim to produced small rotors with a taper of 8 units and each with limits of +/-2 units. Moreover, the production rates and purchase costs of both machines are similar. Each of these machines has also been independently tested for 160 production hours and 10 samples taken representing 5% of hourly production at the beginning of each hour. The Rotomoto Company needs to identify the most cost-effective and efficient machine to invest in. In order to provide a comprehensive recommendation to the manager, a complete statistical process control analysis has been performed based on the available rotor motor data while assuming that non-conforming motors represent a $4 per unit scrap cost. Different descriptive and numerical analysis including data and process analysis were conducted to support the inferences, decisions, and recommendations made. The analysis examined the effects of equipment type and date. Capability analyses were also performed and the information represented in control charts. To establish whether differences in mean and variability exist between the two machines, an appropriate hypothesis test procedure was used. A number of tools associated with statistical process control including control charts, histograms, box plots, and times series were used to present the information obtained from the analysis that was done. The findings obtained are presented in this report, which concludes by providing a recommendation to the Rotomoto Company detailing the most cost-effective and efficient machine that the company should invest in.The Rotomoto Company
