Location Capacity

Requirements | Location Capacity Detail | Related Topics

For a plan produced by any Transportation Management System (TMS) to be operationally feasible, it must have the ability to recognize location resource limitations and account for these constraints while planning pickups and deliveries to and from these locations.

Location capacity allows you to define different types of constraints for a particular location. These constraints limit the amount of work you can do for a specific activity during a time frame (bucket). The system captures the location constraints and reports constraint violations after a shipment is built.

When the Check Location Capacity parameter is set to TRUE, location capacity constraints are honored and the start times chosen so as to minimize the total sum of penalties (below and above target penalties) across all the buckets that the shipment hits. If maximum capacity penalties are violated, the bulk plan fails and does not allow violating the max cap constraints. The shipment start times considered in optimization are dependent on two parameters: Location Capacity Optimizer Time Span and Location Capacity Optimizer Time Step.

An example of where a capacity constraint could be used is when a distribution center has a finite number of dock doors. In this instance, you have a constraint on the amount of shipments you can receive but also possibly on equipment and/or labor to unload the merchandise.

Location Capacity ID uniquely identifies the capacity constraint's name for a location.

In order to set a location time constraint, you need to create a capacity Calendar. The purpose of the capacity calendar is to describe what activities can take place during periods of the day. Multiple activities that have different capacities are allowed to occur simultaneously. For instance, a capacity calendar at a distribution center can be set up to both PICK UP and RECEIVE during the hours 8am to 5pm daily. Below is an example of a capacity calendar that is cyclical:

On "Day 1" the RECEIVE activity is the only activity that can take place between the hours of 9 a.m. to 5 p.m. Notice"Day 3" is repeated in the calendar since the PICKUP and RECEIVE activities can happen together throughout the day. On "Day 5", the same activity is listed twice. By breaking up the day into time blocks, you are giving greater capacity flexibility to an activity throughout the day.

While a capacity calendar is closely related to the business calendar, they should not be combined. When creating a capacity calendar, keep in mind the business calendar of the location. For example, do not set activities to occur when the location is closed. Also,when creating a capacity calendar for a location, OTM will not recognize the "Don't Perform" and "Override" portion of the business calendar.

The relationship between the capacity calendar and a location is established in the location manager roles tab by attaching a Location Capacity Group to the location.

The Active check box turns the location capacity on or off.

Select the Domain Name in which you want to create the Location Capacity. Only domains to which you have access privileges display.

Location Capacity Detail

Location capacity detail recognizes that certain activities have different capacity limitations. The Location Capacity Detail grid relates an activity to a capacity limitation factor and defines how the capacity should be used during a bucket of time.

From the drop down list, select the activity that has a capacity constraint for the location in the Activity ID.

The Capacity Type is the limiting factor for the Activity selected.

The Capacity Allocation Rule wants to know how a shipment at a stop consumes the capacities at your location during a time bucket. There are three ways to distribute your capacity:

The Time Duration Bucket needs to be set up for each Activity instance. A time bucket is a measurement of time that varies for each specific instance.
