A manufacturing firm produces two machine parts, using lathes, milling machines and grinding machines. For lathe operations, part 1 takes 10 minutes for each unit, and part II takes 5 minutes per unit. The firm has a total lathe time of 2500 minutes per week. For milling operations, part 1 takes 4 minutes, and Part II takes 10 minutes per unit. There is a total of 2000 minutes available on the milling machines. For grinding, part 1 takes 1 minute...

LG Company produces three types of parts for automatic vacuum machines. It purchases castings of the parts from a local foundry and then finishes the part on drilling, shaping and polishing machines. The selling prices of parts A, B, and C respectively are Php 80, Php 100 and Php140. All parts made can be sold. Castings for parts A, B and C respectively cost Php50, Php60 and Php100. The shop possesses only one of each type of machine. Cost per...

A plastic injection molding (PIM) machine for Lego figures makes two different parts (yellow bodies and red hats). One of each part goes into a final assembly, and the takt time for the assembly station is the same as the production cycle time = 30 sec/assembly. The cycle time for the PIM machine is 180 seconds to make 18 parts. The setup time to switch between molds on the PIM machine is 12 minutes. To manage inventory, a Kanban system...

Problem 7-15 Chec The Goodparts Company produces a component that is subsequently used in the aerospace industry. The component consists of three parts (A, B, and C) that are purchased from outside and cost 35, 30, and 10 cents per piece, respectively. Parts A and B are assembled first on assembly line 1, which produces 110 components per hour. Part C undergoes a drilling operation before being finally assembled with the...

Problems 1-10 Now you have another piece of information - Table 1. It was either obtained by measuring times to complete each operation, or based on experience with similar operations. For simplicity, setup and cycle times are assumed the same for both 1 and 10.000 parts. To simplify calculations, and without loss of generality, the following is assumed: - The material cost per one part is assumed to be the same, so we neglect it for comparison purposes - Tool...

Elroy had been with Barnes Machine Company a year since finishing a BS in industrial engineering (IE). Barnes had been in business for over 50 years, but the company had only recently moved from Detroit to Gainesville, Georgia. The public reason for the move was the economics of the old facility. Privately, based on comments he had heard, Elroy believed a shift to nonunion labor was a larger motive. Elroy’s boss is the production supervisor, Mr. Hill. Because the plant...

1. The process is performed by several resources. 2. Resources are shared across assembly lines (i.e., workers must multitask and perform multiple activities for every flow unit.) 3. The resource that limits hourly production is not the same resource that limits the process lead-time. From 2002 to 2009, Honda’s 1800cc cruiser-style motorcycle, the VTX1800, was assembled in Marysville, Ohio from four major subassemblies. The following is a simplified explanation of the assembly process. All resources are indicated in bold. •...
