Modeling a belt worker

Hello Everyone.

I am currently employed at UPS ( United Parcel Service). My job there, however quite simple mentally, is the opposite with physicality.
After work is done around 8:30 AM I attend university Full-time. with the long hours, i would like to make my job at UPS a little less exhausting, by the use of strategy, as I am pretty much in peak condition for the job....

So while I was going for a quick jog this evening, I began to ponder a "mathematical" approach ( and i now use the term loosley ) for a maximization of efficiency. As I began to think about what would need to be involved as far as factors and variables, I became overwhelemed, so to speak. The idea of any simple relationship usable in the situation, seemed, with every step, to fly away from my fingertips at sonic speed.

So, to all you higher math buffs and mathematicians, have you ever run across an example of this type of situation in a format that could be of any assitance,.....I 'm guessing probably not , but just wanted to throw it out there....

thanks for humoring me

If they don't they should be spanked.

You need to start with listing the variables that you feel influence your problem. Then you need to determine a formula (function) of the particluar variables.

Then, provided you can go about performing simple calculus for finding maximums & minimums etc. However, this will likely be very difficult if you have many variables.

Proper lifting techniques comes first (ergonomics); then, you might find some efficiencies in how you place the packages for loading and unloading; i'll be your attitude plays a huge part in this. Thus, just the desire to increase efficiency and to begin thinking about how to make improvements is the first step toward making that happen. I'm betting that you will make remarkable progress and will ultimately find huge efficiencies that you can implement. Best of luck.

This is probably why the company doesn't bother teaching various loading techniques.......Since I have been there, I have assesed that memory of regular deliveries ( knowing where and when ...[text shortened]... imesaver, but the knowledege is only gained by expeirience..... so no real strategy there...😳

Efficiency, by definition, is a mathematical statement. It's a ratio of two variables. For example,

If you are trying to load the truck fastest so you can take longer breaks, then your equation is

efficiency = L/T

where T is the Time it took to Load the truck,
and L is how many trucks got Loaded in the Time

If you maximize that efficiency, then you maximize the number of trucks Loaded in a given Time. Note that T/L will not work; I tried that, and realized that maximizing that efficiency means more Time per truck Loaded! That's no what we want. So, it's L/T we want to maximize.

Now you have more numbers to play with, generated by the science. Look at them and see which hypothesis produced the lowest average Time. If you want, you can even do a statistical analysis of Confidence Level to determine if any of the Times are Significantly (by definition) lower or not.

Let's suppose that Not-talking provides a great boost in Efficiency during actual box-loading time. Pull it out of one of the variables we already have, and assign another variable to the Remainder.

E = L/T

L = N*R/T

That is, the trucks Loaded per unit time (which is what L is; it has a Time denominator of 1) is equal to the Not-talking time value (maybe 5.5 minutes if Not-talking, and 6 minutes if allowing yourself to chat) times some other factors we're keeping constant because we're not changing anything except the experimental variable. One variable at a time. They keep adding up and adding up...maybe we discover it takes less time if we carefully wash, massage, lotion and scent our feet in the morning according to a well defined regimen. We'll call that the F variable for Feet.

L = N*F*R/T

I am confusing my self now. I'd have to test to make sure the equations actually describe the observed values fairly well I guess. If not, try to modify the equation.

Those are my thoughts.

They way I see it, the problem, if kept simple will not be very accurate. I am looking for some non-intuitive strategies, and mathematics seems to be good at demystifying these scenarios.

Here are some variables that I percieve to be major factors, just for fun,

Belt speed is constant

thanks

I have read your posts, and your methods of extrapolating the data to find the functions are interesting. Your outline of the procedure to follow is informative, but unfortunately its just not practical in this situatuion....See,... the job seems to be designed to do very little else, other than load the boxes in the 3.5-4 hrs provided......

You said you wanted to make yourself a more efficient worker. As I said, efficiency is a ratio of two variables. Which ratio are we talking about here?

Load trucks fastest?
Load trucks with least wasted space?
Load trucks while expending the least energy?
