1. Brief description

The Supplier (push) object is a kind of inexhaustible source of products and materials.

2. Procedure and control description

Supplier (push) does not require or waits for external orders.

It acts as a source object where required quantity of parts (Number Parts in input) are produced at given time interval (Cycle time in input) through the simulation.

Supplier (Push) without any variation:

Every 1 hour once Product A is produced and transferred to next successor object.

Total of 20 parts is created / produced at the supplier push object without any external orders flowing in from the PPS.

All parts are transported using carriers. With a packaging size of 5, each carrier carries 5 parts from the supplier to the successor object.

The supplier push object continuously pushes the created parts, regardless of the successor or downstream object’s functional status.

Figure 1 - Without any variation

Supplier (Push) with variation in number of parts:

With a 10% variation in production, the output ranges from 18 to 22 parts per hour. The packaging size acts as a rounding factor.

Since each carrier must hold 5 parts, the order quantity is rounded accordingly. For example, when 22 parts are produced, the order is rounded up to 25 parts.

Similarly, when 18 parts are produced, the order is rounded up to 20 parts.

Supplier (Push) with variation in order interval:

With variation in cycle time, orders will not be trigger every one hour. Based on randomization , orders could be triggered in interval which ranges from 30min to 1 hr 30 min.
