Cablesplice, Inc.'s manufacturing process consists of five steps: making con- ductors, adding insulation, adding sheathing, irradiation, and printing and coil cuttingUnits are measured in meters. In 970,000 meters of cable, 700 defects were found in the conductors, and 75,000 defects were found in the insulation. In 440,000 meters of cable, 8,930 defects were found in the sheathing, and no defects were found in the remaining two steps. (a) Find DPU and the dpmo, and (b) the sigma level for each process step.

Quasi-Tech Corporation produces specially machined parts. The parts are produced in batches in one continuous manufacturing process. Each part is custom produced and requires special engineering design activity (based on customer specifications). Once the design is completed, the equipment can be set up for batch production. Once the batch is completed, a sample is taken and inspected to see if the parts are within the tolerances allowed. Thus, the manufacturing process has four activities: engineering, setups, machining, and inspecting. Costs have been assigned to each activity using direct tracing and resource drivers as follows: Activity Expected Cost Activity Driver Activity Capacity Engineering $1,000,000 Engineering hours 5,000 hours Setups 900,000 Setups 200 setups Machining 2,000,000 Machine hours 25,000 machine hours Inspection 800,000 Inspection hours 2,500 inspection hours Quasi-Tech produces two models: Model C and Model D.

The product undergoes the following manufacturing processes: PROCESS CAPACITY/UNIT COST/UNIT EFFICIENCY Kneading 200kg/hr P800,000 85% Cutting 60kg/hr 600,000 90 Drying 500kg/hr 1,200,000 100 Seasoning 75kg/hr 100,000 100 Packaging 2,400packs/hr 250,000 95 If the company is operating at 25 days/month @ 24-hour operation, how much money is needed for the procurement of the machines? How many factory workers are needed in a 2-shift operation if kneading requires 2 operators, cutting - 2, drying - 1, seasoning - 1 and packaging - 3?
Great Valley Income Tax Advice GV is a small accounting firm supporting wealthy individuals in their preparation of annual income tax statements. Every December, GV sends out a short survey to their customers, asking for the information required for preparing the tax statements. Based on 50 years of experience, GV categorizes their cases into the following groups: Group 1 (new customers, easy): 15 percent of casesGroup 2 (new customers, complex): 5 percent of casesGroup 3 (repeat customers, easy): 50 percent of casesGroup 4 (repeat customers, complex): 30 percent of casesHere, “easy” versus “complex” refers to the complexity of the customer’s earning situation. In order to prepare the income tax statement, GV needs to complete the following set of activities. Processing times (and even which activities need to be carried out) depend on which group a tax statement falls into. All of the following processing times are expressed in minutes per income tax statement. The activities are…

ABC Manufacturing is evaluating the desirability of implementing process improvements and is seeking your help in determining whether it should proceed with the proposed improvements. One area of focus is how the improvements will affect processing time (manufacturing cycle time efficiency). Estimated activities and associated times for these activities under both the current process and after process improvements are as follows: Process Activity Current Process After Process Improvements Wait time 4 hours 1 hour Inspection 40 minutes 5 minutes Moving 80 minutes 20 minutes Processing (manufacturing) 2 hours 75 minutes Required: 1. Determine the manufacturing (production) lead time (in minutes) for each of the two decision alternatives. 2. Determine the manufacturing cycle efficiency (MCE) for each decision alternative.
An organization is considering three process configuration options. There are two different intermittent processes, as well as a repetitive focus. The smaller intermittent process has fixed costsof $30000 per month, and variable costs of $9 per unit. The larger intermittent process has fixed costs of $11000 per month and variable costs of $2 per unit. A repetitive focus plant has fixed costs of $48000 and variable costs of $1 per unit.a. If the company produced 22000 units, what would be its cost under each of the threechoices?b. Which process offers the lowest cost to produce 39000 units? What is that cost?
A company that operated 10 hours a day manufactures two products on three sequential processes. The following table summarizes the data for the problem: Which of the following is the most appropriate representation for variables x and y for the given situation? a.) x is the # of units of Product 1 to be procured; y is the # of units of Product 2 to be procured. b.) x is the # of units of Product 1 to be produced; y is the # of units of Product 2 to be produced. c.) x is the # of units of Product 1 to be stored; y is the # of units of Product 2 to be stored d.) x is the # of units of Product 1 to be delivered; y is the # of units of Product 2 to be delivered.

The Trim-Look Company makes several lines of skirts,dresses, and sport coats. Recently, a consultant suggested thatthe company reevaluate its South Islander line and allocateits resources to products that would maximize contributionto profits and to overhead. Each product requires the samepolyester fabric and must pass through the cutting and sewingdepartments. The following data were collected for the studya. How much would you be willing to pay for an extra hourof cutting time? For an extra hour of sewing time? Foran extra yard of material? Explain your response to eachquestion.b.

A local bakery is renowned for its elaborately cecorated sheet cakes. Consider the following process information: One baker is ivailable to prepare the cake batter (measuring and mixing ingredients and then adding it to baking pans). On average, this takes 10 minutes to prepare two cakes, ie. to make enough batter for 2 cakes and to add the batter to 2 cake pans. Move time to add and remove them from the oven is neglig bile, it takes 32 minutes to bake cakes - the bakery has two ovens, each able to hold 2 cakes. The one pastry chef on staff puts on an amazing show that draws a crowd all day-each cake is decorated in 6 minutes. The bakery operates 8 hours per day. Answer each of the following questions: a. What is the cycle time (in minutes per cake) of each stage - preparing, baking, and decorating? b. What is the dally process capacity? Explain. c.
