Presentation Transcript

Slide 1

Item Design and Process Selection Based on slides for Chase Acquilano and Jacobs, Operations Management, McGraw-Hill

Slide 2

What is a Product? An item is a bundle of : Goods Services Experiences Ongoing Relationships An item has: Tangible characteristics Intangible qualities Examples Automobile Airplane trip Diamond Ring Restaurant Meal Dishwasher College Education Tax Preparation Basketball Game

Slide 3

Product Design Issues Value examination/esteem building Obtain better execution at lower cost Two Design Approaches: Over the Wall Approach versus Simultaneous Engineering Complexity of outline Implications?? Unwavering quality How would it be able to be expanded? Institutionalization Advantages & inconveniences? Secluded outline Advantages & inconveniences? Ecological Implications

Slide 4

Exercise Pick a few items and show a few issues that should be considered in its plan and fabricate Include stylish, manufacturability, after-deals benefit issues among others Deliverable List and present to the class

Slide 5

Process Selection

Slide 6

Process Structures Continuous Processing Repetitive (sequential construction systems) Manufacturing cells Batch handling Job Shops Projects "persistent or semi-ceaseless" "irregular"

Slide 7

Example: Job Shop

Slide 8

Example: Batch Processing

Slide 9

Example: Assembly Line Processing

Slide 10

Example: Continuous Processing

Slide 11

Manufacturing

Slide 12

Break-Even Analysis Some administrative inquiries: How much would it be advisable for us to create to make back the initial investment? For a particular volume, would it be advisable for us to make the item ourselves, or outsource? For machine choices An and B, at what volumes would it be a good idea for us to utilize machine An and at what volumes, machine B?

Slide 13

Break-Even Analysis (illustration) Sale Price = $300 Option 1: Purchase = $200 * Demand Option 2: Lathe = $80,000 + $75 * Demand Option 3: Machine focus = $200,000 + $15 * Demand Purchase versus Machine? Machine versus Machining Center?

Slide 14

Calculations Purchase versus Lathe: $200 * Demand = $80,000 + $75 * Demand ($200 * Demand) - ($75 * Demand) = $80,000 $125 * Demand = $80,000 Demand = $80,000/$125 = 640 units so – under 640 units, buy; 640 of more prominent, utilize Lathe versus Machine Center: $80,000 + $75 *Demand = $200,000 + $15 * Demand Demand = $120,000/$60 = 2,000 units so – less that 2000 units utilize the Lathe; at least 2000 utilize the machining focus

Slide 15

Break Even Analysis Example You are beginning another business and your settled expenses are evaluated to be $500,000. Your item offers for $100 and costs you $50 to make. What is the breakeven point? On the off chance that you offer 15,000 units, what will be your benefit? Reply: Break Even Value is 10,000 and Profit is $250,000

Slide 16

Break Even Analysis Formulas Total Revenue = Total Cost P x = F + V x infers: BEP(x) = F/[P-V] Profit = TR-TC = (P-V) x – F Breakeven between two machines: F 1 + V 1 x and F 2 + V 2 x - expect F 2 > F 1 & V 2 < V 1 (F 2 – F 1)/(V 1 – V 2 ) Note: F = Fixed Cost; P = Price; V = Variable Cost

Slide 17

Break Even Analysis Example In your business you are thinking about two machines. Machine 1 costs $500,000 and has a variable for every unit cost of $50 per thing. Machine 2 has a settled cost of $200,000 and has a variable for each unit cost of $80 per thing. What is the make back the initial investment volume for the two machines. In the event that a companion instructs you to utilize Machine 2 if the volume is 5,000 things, would she say she is correct or off-base? Reply: Break Even Value is 10,000
