Today, we'll calculate the downtime costs associated with our equipment. Can anyone tell me how we start this calculation?
Is it based on the equipment cost?
Exactly! The downtime cost per hour is a percentage of the equipment cost. For example, if our equipment costs 900 rupees per hour and the downtime percentage is 3%, we multiply 900 by 3%.
So, that would be 27 rupees per hour?
Correct! Now, if this machine operates for 2000 hours a year, how do we calculate the yearly downtime cost?
Would it be 27 times 2000?
Exactly! That gives us 54,000 rupees for the first year. Remember, we use D= (P * C), where D is downtime cost, P is percentage, and C is equipment cost.
Can you explain C like a memory aid?
Sure! Think of 'D' for downtime as 'P' for percentage affecting 'C' for cost. Together they show us how much downtime will cost us!
Let’s summarize: We learned how to find downtime costs using the equipment cost and percentage of downtime. Great job, everyone!
Now that we know the yearly downtime costs, let’s talk about cumulative costs. Can someone explain how we might find these?
Is it just adding each year’s downtime costs together?
Yes! So for the second year at 108,000 rupees, we add this to the previous year’s cost. What do we get?
We would have 162,000 rupees after adding them?
Exactly! Now, why do we need to adjust for productivity?
Because if the machine isn’t working, it’s affecting our production rates?
Correct! If productivity drops to 0.98, we need additional costs to bring it back. This leads us to our productivity adjusted cost calculation. Who remembers the formula?
You divide the cumulative cost by productivity, right?
Exactly! This adjustment helps illustrate true costs affected by machine downtime.
To summarize, we learned how to calculate cumulative costs and make adjustments for productivity to understand the total cost implications. Awesome work today!
Now let’s explore the concept of obsolescence cost. What do you think this cost includes?
Does it involve keeping old equipment that isn't efficient anymore?
Right! It encompasses costs associated with reduced productivity and increased repairs due to age. How would we estimate this cost?
We calculate it as a percentage of the equipment cost, similar to downtime?
Exactly! If obsolescence is 0.05, then for the equipment cost of 900, we calculate a cost of 45 rupees per hour. Why does this matter?
It affects how competitive our production is?
Yes! Remember, lower productivity and higher costs can lead us to reconsider replacing older equipment.
In summary, obsolescence cost reflects costs accrued by retaining old equipment. Wonderful discussion!
Today, we’ll conclude by discussing economic life. Why is it important to know?
So we know when it’s time to replace the machine?
Correct! This involves identifying the lowest cost per operating hour. What’s one factor that affects this economic life?
Increasing maintenance and repair costs, right?
Absolutely! The trend can appear parabolic, showing decreasing costs initially followed by an increase after a minimum point. How should we act when we observe rising costs?
It’s best to replace the old machine before costs get too high!
Exactly! The best time is before significant losses appear. Any final thoughts on how often we should review equipment?
Regular assessments can help us stay ahead of costs!
Great contribution! To summarize, we learned that economic life indicates when to replace equipment to minimize costs. Excellent participation today!
Cost incurred when equipment is not operational, impacting productivity.
Total accumulated cost over time, critical for long-term profitability analysis.
Increased costs associated with using outdated machinery, affecting overall efficiency.
The optimal duration for utilizing a piece of equipment for the lowest cost impact.
To calculate downtime, just remember this line, Equipment Cost times the downtime percent, it's a simple design.
Imagine a factory where the old mill often stops, employees become dismayed. Each hour lost costs money, and managers need to plan for new machines to keep production relayed.
To remember economic life costs: D, C, O, and E --> Downtime, Cost, Obsolescence, and Economic Life!
Use 'C.O.D.E.' to recall Cumulative, Obsolescence, Downtime, and Economic life.
