Question

Can anyone assist me with the following problem posted below? I just need some simple use case diagrams made for all the systems at play as described, ill do my best to answer any questions you may have, thank you!

SYSTEM DETAILS:

The warehouse stores items for purchase by customers. To expedite order fulfillment, stock of most items is kept and a minimum reorder is made when stocks are below a set trigger quantity. Items ordered that are not in stock are special ordered for the customer. Each item stocked by the warehouse is tracked so that it may be located when needed. The warehouse may have items in three general areas: receiving room, stock room, or the order room. Stock received at the warehouse is initially processed in the receiving room. Stock is stored in the stock room. Like items should be store next to each other. Large items are placed on shelving while smaller items are placed in bins on the shelves. Shelves are numbered and each bin on a shelf are lettered.

When an order is placed a list of items to collect and bring to the order room. The order room has pallets and bins to organize and ship items to customers. A warehouse worker performs this task. The worker interacts with the system to initial the completion of the order.

Some items are uniquely identified. There are two methods, a unique serial number or rfid tag. Items with an rfid tag will have a serial number.

Ordering for items not in stock is currently done by the warehouse worker who is the one discovering an item is not in stock. The system should automatically create an order to suppliers for items not in stock when the sales office creates the customer order.

The customer is billed for each shipment (full or partial) when the shipment is made. The accounting department will access the system for shipments to get the invoice for a shipment. At this time the commission amount for a sales person is calculated. Commissions are paid weekly and are currently manually entered into the payroll system.

Accounting also queries the system weekly for inventory valuation. This process generates orders for any items at stock levels beneath the reorder trigger point.

Answer 1

Here we need to draw the usecase diagrams.

Usecase Diagram:

Usecase Diagram is diagram by which we can represent the user's interaction with the given system which shows the association between the user and different usecases.

While we go for Usecase diagram of the above mentioned system. We need to keep some of the points in our mind.

And they are as follows,

* To perform order fulfillement, stocks of the most items is kept. A minimum reorder is made when stocks are below to a set trigger quantity.

* Items ordered that are not in the stock are special orders to specific customers.

* Each item in the warehouse is got stocked is tracked so that it may be located when needed.

* Warehouse generally has three rooms namely,

i) Recieving Room

ii) Stock Room

iii) Order Room

* Like items should be stored next to each other.

* Large items should be kept in shelving, small items should be kept in bins on the shelves.

* The following usecase diagram has five actors,

i) Customer

ii) Sales Person

iii) Warehouse Manager

iv) Warehouse Worker

v) General Manager
