a)
To determine: The upper and lower control limits for the control chart and graph the data.
Introduction: A process is said to be operating in “statistical control” when all the variations in the process that are due to assignable causes have been identified and removed. In other words, the only variations are due to natural causes. In such a state, the process is said to be in “statistical control”

- Is it hard to improve efficiency in a process? Why or why not? Give an example of how to improve the efficiency of a process. Please provide a reference in APA formarrow_forwardSimplex Method Three types of paints are manufactured in one machine; Interior paint, Exterior paint and Paint for metal structures. The preparation time for each type of paint is 2, 3 and 4 minutes respectively and the processing time is 3, 2 and 1 minute. The profit contributed by each product is 12, 10 and 15 dollars respectively. The machine availability is 100 minutes and 200 minutes for machine setup. 1. Determine the optimum number of types of paints to be manufactured. 2. Determine the optimal utility value.arrow_forwardThe company LED S.A DE C.V. produces 2 devices for lamps, devices 1 and 2 that require metal parts and electrical parts. The manager wants to determine how many units of each product should be manufactured to maximize the profit for each unit, device 1 requires 2 metal parts and 4 electrical parts, device 2 requires 4 metal parts and 2 electrical parts, the company has 24 units of each material available for batch production, device 1 generates $4 profit and device 2 generates $6 profit. a) Formulate PL model. b) Solve by the graphical method and determine what is the resulting maximum profit.

The goal is to locate at a minimum-cost site, where cost is measured by the annual fixed plus variable costs of production. Hyundai Motors has gathered the following data: Site Annualized Fixed Cost Variable Cost per Battery Produced A $11,000,000 $2,600 B C $2,000 $1,100 $20,000,000 $25,000,000 The firm knows it will produce between 0 and 60,000 batteries at the new plant each year, but, thus far, that is the extent of its knowledge about production plans. a) The value of volume, V, of production above which site C is recommended = batteries (round your response up to the next whole number).arrow_forwardHyundai Motors is considering three sites-A, B, and C-at which to locate a factory to build its new electric car batteries.
