Calculation to estimate number of optimum manpower requirement

I have been tasked to come up with scientific procedure to calculate the optimum number of manpower required to maintain refining facilities. Can anyone suggest any references, formulas, or book that I can refer to?



Thanks,

First, you should have some knowledge of work measurement. If you don't, get one. Since your question is about 'optimum' requirement, it is fair to assume your estimate must be based on engineered standard. Don't have engineered standards, get one or lower the bar to a rough estimate or ?<br>Once you have decided what exactly you want in terms of accuracy of the estimate, proceed by developing rate for each activity at the refining facility - time consuming and no short cuts. <br>Your estimate then breaks down to how many people are required for each activity in the refinery? The sum of all the people required is your requirement.<br>

I was recently hired as a production engineer for a factory which design and produce office and shop furniture, mainly made of steel.
There is per today no procedures for calculation of direct cost in the production. One of my duties will be to create and implement a system for calculation of the cost of each component in the production. By breaking down each finnished product to simple componets. I will then try to see how much each operation (such as welding, drilling, bending, shearing etc.)will cost for each component.

My question is: Is there any standard system for calculating the cost of operations such as cost per mm TIG welding on a given type of profile? If there is, does this standards differ between industrial work and fine finnish?

Can anyone give me a tip or atleast give me an idea about litterature about the subject? [sig][/sig]
