Help with X-Ray Machine Cost Calculation

AI Thread Summary
The discussion revolves around calculating costs related to an x-ray machine setup for processing employees. The user is confused about distinguishing between waiting costs, service costs, and fixed costs, despite having the necessary data. They mention that 20 scientists arrive per hour while the x-ray station can handle 45 per hour, leading to excess capacity. The total cost per employee is $65 per hour, with machine costs at $50,000 and operator wages at $30,000 annually. The conversation highlights the need for clarity on cost categorization rather than the mathematical solution itself.

I have to solve this exercise and i stuck any help?
we have 20 scietists arrive per hour and the x-ray station can process 45 employees per hour. the company spends a total of $65 per hour per employee. X-ray machines cost $50.000 and the wages and fringe benefits of operators amount to $30.000 per year. how many machines will we buy? my question is not how to solve the problem (i have a programm to do that) , but i have a hard time to understand which is the waiting cost and which tha service cost and we also have a fixd cost to... help please!

Your rate constant is 20 is events per hour for scientists, so your mean waiting time between arrivals is 0.05 hour (it's always better to keep everything in terms of the same time unit). Can you take it from there?

I'm looking for the waiting cost and the service cost.. It's already given in the topic the numbers but I'm not sure which is which because there is also a fixed cost included .. I'm looking for the data of the problem not the solution.. i hope i was clear!

We generally don't answer these types of questions. This is a math/science forum, not an accounting/business forum. Since you already claim to know the math, you can see you have excess capacity which is costing money. Perhaps someone else will help calculate the costs for you. And please, no more of the "!"

Thread 'Deductive proof in logic formal systems'

I was reading documentation about the soundness and completeness of logic formal systems. Consider the following $$\vdash_S \phi$$ where ##S## is the proof-system making part the formal system and ##\phi## is a wff (well formed formula) of the formal language. Note the blank on left of the turnstile symbol ##\vdash_S##, as far as I can tell it actually represents the empty set. So what does it mean ? I guess it actually means ##\phi## is a theorem of the formal system, i.e. there is a...
