Talk:Material handling

Proposed Major Change to Article
I have created an expanded version of this article (see https://en.wikipedia.org/wiki/User:Mgkay/Material_handling) and would like to propose it as the new base article for the topic, from which others can expand it. I am an academic and have taught and done research in material handling for many years. I have tried to make it concise and comprehensive and have included citations for everything in the article. Please let me know your comments regarding the change. Michael G. Kay 19:01, 21 September 2015 (UTC) — Preceding unsigned comment added by Mgkay (talk • contribs)

OR equation
I made the addition in bold below, but my actual feeling is that this is all too OR to remain here.

A rough guide to determine how much can be spent for automated equipment that would replace one material handler is to consider that, with benefits, the median moving machine operator costs a company $45,432 per year. Assuming a real interest rate of 1.7% and a service life of 5 years with no adoption/adaptation cost, no learning cost, no training cost, and no operating cost for equipment with no salvage value, a company should be willing to pay up to

$$\$45\,432\left (\frac{1-1.017^{-5}}{0.017} \right )=\$45\,432(4.75)=\$219\,019 $$

to purchase automated equipment to replace one worker.

All the equation illustrates is a technical handling of an interest rate discount over five years, plus a bunch of numbers "conservatively" plucked.

But I incline to more over less, so I'll leave it for the next editor to decide. &mdash; MaxEnt 01:19, 5 January 2022 (UTC)
