• Horizons for TLB<br />

The most important horizons for TLB are the planning horizon and the<br />

pull-in horizon. The TLB planning horizon defines which distribution orders<br />

are taken into account for the TLB run, and the TLB pull-in horizon<br />

defines which orders might be scheduled forward and is maintained in the<br />

transportation lane itself. Looking from the earliest order, other distribution<br />

orders <strong>with</strong>in the TLB pull horizon are combined as shown in figure<br />

TLB Run<br />

With the new TLB algorithm the days of coverage at the target location (a<br />

setting in the locationproduct master) can be used as well to influence the<br />

decision whether a deployment order is moved forward and combined <strong>with</strong><br />

another order or not.<br />

• Capacity Restrictions for TLB<br />

Capacity constraints are only considered as defined in the TLB-profile.<br />

Other capacity restrictions – e.g. the capacity of the transport resource –<br />

are ignored during the TLB run. If transport resources are a capacity constraint,<br />

these have to be considered in the distribution planning resp. the<br />

deployment run. The relevant capacity restriction in the TLB profile is<br />

the minimum of the three following constraints: the maximum volume,<br />

the maximum weight and the maximum number of pallets. A lower limit<br />

exists as well to inhibit uneconomical transport orders. The volume and the<br />

weight limits are checked using the volume and the weight properties in<br />

the ‘attributes’-view of the product master. The standard parameters are<br />
