The description for transportation lanes starts here, in the menu on the left side you'll also see the means of transport:

Have fun going through it.
And sorry, I won't create an example in our APO test system and debug it together with you so I can really prove this. Believe me or not, I don't give a shit.
Ziggy Stardust wrote:This statement completely betrays your utter ignorance of the issues we are talking about. A logistic network BY DEFINITION is more than just a one-way transfer of goods from point A to point B. Literally the entire science of supply chain management is based on the fact that logistics networks for any reasonably sized organization are FAR more complicated than simply "one-way trip from China to the USA", and that they need to efficiently move goods from multiple origins to multiple destinations over myriad distances within a finite period of time with finite resources.
You don't seem to know how SCM planning works:
First, you have a
demand in a
Location(from Sales Orders, Planned Independent Requirements, Scheduling Agreements etc.)
Then, if you don't have the products in stock, you create a
receipt to cover your demand (e.g. Purchase Requisition/ Order, Stock Transport Order), thereby taking the transport duration, goods receipt processing time etc. into account.
Afterwards, you do the
transport planning, which of course isn't trivial. But still, usually you plan a point-to-point transport which has nothing to do whatsoever with the travelling salesman problem.
Of course, when your network is complex enough, in the end you use heuristics or optimizers to plan the transports, which you probably mean with "they need to efficiently move goods from multiple origins to multiple destinations over myriad distances within a finite period of time with finite resources."
Ziggy Stardust wrote:Seriously, how fucking stupid can you be? You apparently don't even know the definition of "logistics network." Here, let's extend your own example. You have a Purchase Order with the vendor in China; where in China is the product produced? How is it transported to the airport or seaport where it will be transferred internationally to the USA? Where in the USA is it going, and how will it get there? Even in your moronic oversimplification you have glossed over a wide variety of pertinent details in logistics management.
This is utter bullshit. You simply maintain your transport duration between 2 locations, which of course has to take that into account. But the SCM system doesn't care about such details which are unimportant for the planning itself. Loading/unloading etc. is modelled
in the transport duration
The details are taken care of during
supply chain execution, not planning

Show me a single SCM planning software solution where the distance is used for actual supply network planning, and not just as descriptive field or STFU.

You just dodged it with another vague reference to software, which is utterly irrelevant (and unsubstantiated ... you have not produced any evidence in this thread that you have any relevant experience with the software, or how that software is relevant to what we are talking about, or that you have ever even SEEN this software ... we are not taking your dishonest word for it, shitstain).
So you cannot name a software suite which plans with distance instead of duration. Concession accepted.
Ziggy Stardust wrote:IS TRANSPORTING SOMETHING 2 HOURS BY AIRPLANE THE SAME AS TRANSPORTING SOMETHING 2 HORUS BY TRUCK? Yes or no, asshole. You are claiming duration is the ONLY variable necessary in planning transportation, despite the fact that multiple sources from academic journals in the field of question disagree with you. YOU need to justify your claims, I have already justified mine.
It's not the
only variable, you fucking idiot. As I already have stated, the second variable usually is
cost (when you use an optimizer for the planning).
For heuristics, things can look different depending on the exact algorithm used (e.g. by using pre-set priorities to determine the "best" transportation lane)
And you have justified jack shit, you have just googled some articles, which everybody can do. But you have no clue how such systems work in real life. Check at
http://www.help.sap.com, this should give you a clue (the sofware suit for SCM is called APO (Advanced Planner and Optimizer).
BabelHuber wrote:Okay, guess we have to uses buses instead of planes from now on, because 2 hours by bus is the same as 2 hours by plane!
Yes, because a bus can cover 1,600km in 2 hours
BabelHuber wrote:Are you really so stupid that you can't understand the massive difference between transporting something 2 hours by air versus 2 hours by bus?
You don't understand how planning systems work, so you come up with fucking bullshit like this. When I have a demand which can be covered by 2 locations:
Location A is 150km away (2 hours via bus)
Location B is 1200km away (2 hours via airplane)
Then the system selects a location (it would usually take the bus, this is cheaper). Afterwards, it doesn't give jack shit about what the means of transport is, except if you have a delay. In this case, you get an Alert.
Ziggy Stardust wrote:This is all utter gibberish, completely ignoring the point. Since you are apparently too stupid to understand this, PLANES TRAVEL FURTHER THAN BUSES IN THE SAME AMOUNT OF TIME. Why the hell do I need to spell this out for you? Transporting something 2 hours by plane is NOT the same as transporting something 2 hours by bus, because they travel MASSIVELY different distances within that same time frame, which effects how and when you decide to use one means of transport versus the other. If you are trying to transport something 2000 miles, a plane is more efficient than a truck. DISTANCE IS THE CRITICAL FACTOR. Just as all of the links I posted in my last posted showed. Again: I have presented my evidence, YOU NEED TO PRESENT YOURS. Your say-so won't do it.

Ziggy Stardust wrote:It's not nitpicking. If you really don't understand the difference between "cheap" and "efficient" you aren't qualified to talk about supply chain management. Period.
You are full of shit. You can use a
cost-based approach or
set priorities (depending on the algorith used for planning). This way you model your decisions period.
Since you don't get the difference between supply chain planning and transport planning, it would be better for you to shut the fuck up, you are mixing up things here.
Ziggy Stardust wrote:This is blatantly false. Air transport is cheaper than sea transport, for a variety of reasons. However, if you are trying to move large tonnage, sea transport is more efficient because ships can carry more than a plane. This is incredibly basic stuff, here, of which you are apparently utterly ignorant.
I have yet to see a company which prioritizes airfreight over sea transport
if the ship is fast enough.
You know, you wouldn't load a ship with 1% of the cargo it can carry and send it away, you would put a few containers on a ship which does the travel anyways in this case.
I take this for granted when talking about such topics, but you try to be a wise ass by stating that it is inefficient to load a ahip with a few containers and let it drive 99% empty. Everybody knows this, there is no reason whatsoever to even talk about such shit.
Ziggy Stardust wrote:You have clearly never seen a supply chain AT ALL, given the idiocy you have said in your thread. "DISTANCE DOESN'T MATTER IN SUPPLY CHAINS LOL".
Distance
technically does not matter for supply network planning, duration does (and cost). But as I said, I won't debug a system for you to prove it. If you don't believe me, believe whatever you want.
Ziggy Stardust wrote:So you seriously think the ONLY reasons there are thousands of cargo planes transporting pharmaceutical goods is that the companies are incompetent with their planning? I guess they should hire you

They actually
do hire me to enhance their SCM planning capabilities.
You don't seem to understand this, but planning fails all the time: You have unplanned machine downtimes, delays in the receipt of components you need for production, people get sick so there is no personal available to handle some machines on the shop floor etc.
The fact that you don't know this speaks volumes.

Look at help.sap.com if you don't believe me,
technically SCM systems don't work with distances, but with durations (and assigned costs/ priorities)
If you don't believe this, I don't give a shit.
