Beverage manufacturers are facing various problems.

  • The tank used in the blending process cannot receive the next raw materials until the input raw materials have passed to the following process.
  • There is the constraint that, since the tank and filler are connected, once the tank is determined, the filler is also determined.
  • In the case of a tank for blending raw materials, which is equipped with an agitator propeller, not only the upper limit of capacity, but also the lower limit must be considered.
  • The operation must be split so as to enable as much bottle filling as possible using the amount that flows from the blending process.
  • The cleanup that goes along with the raw material switching in the blending process, and the bottle size switching in the filling process must be taken into consideration.

We will describe how to solve these problems with scheduler

67.00 Overview  
67.01 Master data settings and finite capacity scheduling

During operation, the master data required for scheduling can be automatically imported from a mission-critical system and so on.
However, to explain the registration method and the required information, we will describe the manual input method.
A production plan can be created by simply registering the raw materials and production equipment for the item for which the schedule is to be created.
 
67.02 Resource lock

Unlike processing equipment and assembly lines, tanks cannot receive the next raw materials until the input raw materials have passed to the following process.
This can be taken into account in the schedule with the resource lock function.
By using resource lock, time relationships among processes can be taken into consideration to ensure that other operations do not cause interruptions.
 
67.03 Constraint 01_ Next Resource

When filling with beverage, once the tank is determined, the filler is also determined.
Such a constraint is called a next resource constraint.
Highly accurate plans can be created when it is not possible to assign resources other than the set resources as the next resources and when it is not possible to move resources manually on a Gantt chart.
 
67.04 Constraint 02_ Tank Capacity and Batches

The tank capacity is an important constraint when creating a production plan.
Particularly in the case of a tank for blending raw materials, which is equipped with an agitator propeller, not only the upper limit of capacity, but also the lower limit must be considered.
With Asprova, you can easily carry out scheduling with constraints on the upper and lower limits for tank capacity.
 
67.05 Split Operations

Splitting the filling process operations so as to achieve filling at the optimum timing is best.
Here, we will split the operations based on the quantity to be flowed from the blending process, in other words based on the amount of reserved raw material.
An appropriate schedule can be created by further taking into account the reserved quantity for the batch size.
 
67.06 Setup and Maintenance (Cleanup)

The beverage production process involves setups when raw material and product are switched.
Schedules that take into consideration setups can be created by setting the setup times required when switching items.
 
67.07 Import Result and ATP

It is now possible to create a schedule by registering the scheduling requirements related to beverage production.
In other words, as work instructions can be created, let's look at a series of operation cycles.
As new orders are being added daily, let's create a schedule while reflecting the results from the production site.
 
67.08 APS

let's include customer order entry, inventory, and purchasing in the beverage production process plan.
With Asprova, you can achieve total optimization including customer order entry, inventory, and purchasing, besides production.
 
67.09 Plug-ins

Thus far, we have introduced standard functions and options.
Additionally, we will offer SDKs and plug-in samples that allow free development of features for industry-specific requirements.
For beverage production, a fragrance contamination prevention function sample is available, so let's take a look at it.
