Can AI play a role here by predictively analysing the customer order patterns? Can a grocery order be auto-triggered?

We have a 3 way powered recommendation engine that uses content filtering, collaborative
and past order history based recommendations to suggest the most effective and nearest 
matching products to the users.

Content based filtering suggests, how products with similar tags are selected and suggested 
to the user. Care is taken to ensure that tags for multiple products are properly analysed 
before recommending anything. Collaborative and past order based recommendations are quite 
similar apart from a few points. Users with a similar order history or similar likes or dislikes
are suggested near alike products.

Using the apriori algorithm, we can determine patterns and trends in an user’s past orders based
on pruning frequency and candidate items to improve joining efficiency. This algorithm can also 
be used to determine recurring orders and send push  notifications to the user for the same.

Can Kiranas play a role in quicker deliveries? If yes, how can it work at scale?

As per the basic flow of the system, first the customer places an order and we get the coordinates of 
the customer via device location and then scans all the nearest shops and delivery agents in a 5km radius.

Then we will assign the order to the nearest shop and the delivery agent based upon a distance matrix as
shown above. The shop is selected based on the availability of the product and the number of pending 
orders in the shop. 

A job is pushed using RabbitMQ and the shopkeeper gets an alert message and has a 2 minute window 
to accept the order failing which the order will be passed on to the next available shop. After the 
job is acknowledged it is popped from the queue. Next the delivery agent will receive a job through 
RabbitMQ. The delivery agent also has to accept the job within 2 minutes or else it will be passed 
on to the next agent.

Accordingly a final decision is made and the product is delivered

In Tier-1 cities, our societies are now digitised, courtesy the likes of Mygate. Can this prove to be a fundamental block in achieving higher speed of deliveries? (Relay deliveries)

We have also incorporated a feature which plays a fundamental role in relay deliveries.  We will 
ensure that products ordered at same time from nearby localities are ordered to the customers via the 
same delivery agent therefore keeping the max possible delivery agents available for further orders.

Suppose customer 1 and customer 2 from nearby localities order products at the same time, their 
orders will be delivered via the nearest same delivery agent. This facilitates relay deliveries and 
ensures max possible delivery agents are available for further orders.
