Methods and apparatuses for recommending substitutions made during order fulfillment processes

The system of claim 7, wherein the overall substitution score is determined using the formula:

• Sub_score(i_a, i_aj, cust)=λ*rel_score((i_a, i_aj)+(1−λ)*pref_score(item_attr(i_aj), cust_attr(cust))
• where:
• Sub_score=overall substitution score
• rel_score=relevance score
• pref_score=preference score
• λ=score parameter
• item_attr=item attribute
• cust_attr=customer attribute

A method comprising:

• obtaining item attribute data that corresponds to a characteristic of an item ordered by a customer on an e-commerce platform and a common characteristic of a plurality of substitution items;
• obtaining customer attribute data identifying preferences of the customer;
• determining a preference score for each substitution item in the plurality of substitution items based on the item attribute data and the customer attribute data, the preference score indicating a likelihood that the customer will accept one of the plurality of substitution items as a replacement for the item ordered by the customer;
• and
• ranking each substitution item in the plurality of substitution items based on the preference scores.
