Weight restriction by OD pair or route

[Former Member]

All,

We have a requirement that the weight loaded on a rail car going to a specific location (plant/shipping point) cannot exceed certain weight (e.g. 160,000LB) due to the rail track restriction. The rail car resource however is a regular one whose capacity is the usual one (e.g. 185,000 LB) therefore resource master cannot be updated nor can we use an incompatibility given the possible types of incompatibility provided. Is there a way we can ensure rail cars exceeding this weight are not assigned to an RCU (or a freight order) if they are destined from a certain location to a certain location? We are using default routes so if it's possible to do at a route level that will work too as we can configure unique route for this case.

Best Regards

Hi,

Are you working on TM 9.1 version since there are couple of useful functionalities on rail scenarios applicable from this version

Hi Indraneel,

Yes we are using TM 9.1.

Hi,

One way which I suppose us to use conditions concept using BRF plus whereby based on shipping conditions and other parameters like routes ID/location ID  etc you can use weight as a parameter and specify the weight as a restriction there.

Thanks Indraneel, could you please advise what condition type do we use and where this condition comes into play in RCU/FO processing.

Hi,

One of the way is  to use condition type /scmtms/tor_def_MTR where you can use the data access defination for condition field-/scmtms/for_TOT_WEI whereby the weight i.e the capacity  that the FO can carry can be restricted based on various means of transport.In the DAD condition field you can add more fields like locations etc and then assign this condition in the MTR determination field in the SPRO node of freight order type.

Via this way the system will determine the valid means of transport based on the total weight of the freight order and without using the updation of resource capacity.

Indraneel,

I think you are suggesting we determine a different means of transport using a condition. Let's say we define a new means of transport and determine it for this particular route. When the user later assigns a rail car resource that has heavier load and belongs to another means of transport what is the system behavior - do we get a warning or error or does the system overwrite the means of transport with the one that's on the rail car resource?

Hi,

In the project which I was working we had 2 alternatives:

a) In the FO type definition, we assign a planning profile. And in this planning profile, we  can use a incompatibility setting. A rail car unit is also a transportation unit technically. So in this

incompatibility setting, check if you can use incompatibility type definition of type 'RCU  unit - * '. Incompatibility area can be 01 ( complete VSR).  This way, when a RCU is assigned to FO,

incompatibility setting will be checked.

b) If we  are using optimizer for planning, we can also use the BADI to influence the inputs to optimizer.

The BADI is /SCMTMS/PLN_PRE_PROC  and enhancement spot is /SCMTMS/PLN_OPT .This BADI can be  used to restrict the inputs i.e RCU  passed to optimizer planning.
