How should the workload be calculated?

2008-01-20View Original

Thread Content

Suppose a plant has a capacity of 100,000 tons and requires an investment of 200 million; for a plant with the same production capacity but a smaller size, the investment is 15 million. I would like to ask whether, in terms of design, the workload involved in designing such a smaller plant is only 1/10 of that for a larger plant?

It can’t be calculated in this way; the small device mentioned by the original poster might be a pilot-scale device. When scaling up such a device, it cannot be assessed solely based on size and production capacity – factors such as the actual manufacturing process, energy consumption, and equipment also need to be taken into consideration

The workload is roughly the same, as the workload for each involved specialty is more or less equivalent; it’s just that on a smaller scale, the calculation complexity for each specialty is lower, and there are fewer drawings for some specialties (such as structural drawings).

To be more precise, the job responsibilities are the same, because even though it’s a small entity, it has all the necessary components – all the specialized functions that are required. But the workload is different. For volumes of 100,000 tons and 10,000 tons, the process routes need not be identical; even if they are exactly the same, the supporting infrastructure required differs significantly. The workload is certainly not 1/10 of what it would be in such cases – it depends on the specific circumstances. Generally speaking, the workload for a smaller scale facility is only about 1/3 to 1/2 of that. The project timeline remains largely unchanged.

The workload and job responsibilities are basically the same; none of the necessary specialties is missing. Moreover, it’s completely the same process; the manufacturing procedures, piping, and so on are all identical. It only takes into account some computational issues, and there are significant differences in areas such as civil engineering and structural design. So, the workload and job responsibilities are basically the same. The effort required to calculate 1+1 and 3+3 is the same; it’s the same type of calculation, with only different numbers being used. It’s the same principle: loveliness:

It seems to be closely related to the amount of investment; every time the price of a contract is discussed, those older people calculate the investment amount for that project, and then use a formula to determine the price based on the complexity of the manufacturing process and other factors.

The workload is basically the same; it’s just on a smaller scale, but everything that’s necessary still needs to be included.

Ugh, what kind of question is that? How could there be such a big difference?

The workload is not calculated in that way; in fact, whether on a large scale or a small scale, its structure remains basically the same. It’s only the size of the equipment and the area of land required that change, and the difference in workload isn’t that significant.

I’m also really curious about how the workload in the company is calculated; I’m interested :lol

It’s definitely not right to do it this way; it’s not something that can be achieved by drawing analogies. You can refer to the relevant engineering design fee standards.

Estimate the number of man-days required, as well as how many drawings are needed – that constitutes the basic workload.
