Client Arrival and Demand Generation

Client Arrival Module

• The process begins with a "create" module that generates client arrivals, which occur uniformly between 3 to 7 hours.

• A variable named "total number of clients" is introduced to keep track of the cumulative count as new clients arrive.

Demand Generation

• An "asing" module is utilized to generate demand for each client, set uniformly between 50 and 100 units.

• The system allows for decimal values in demand rather than restricting it to integers.

Inventory Check and Demand Fulfillment

Checking Inventory

• A decision-making module checks if inventory meets or exceeds the client's demand, determining whether fulfillment is possible.

Handling Sufficient Inventory

• If inventory suffices (true), it updates the inventory by subtracting the fulfilled demand.

• It then checks if the remaining inventory falls below a reorder point, triggering production if necessary.

Handling Insufficient Inventory

• If there isn't enough inventory (false), the client is removed from consideration using a disposal method.

Lost Clients and Statistics Tracking

Managing Lost Demand

• When demand cannot be fully satisfied, a variable tracks lost clients, incrementing by one for each unsatisfied request.

• Another variable records the quantity lost (demand minus available inventory), resetting available inventory to zero after fulfilling what was possible.
