Objectives/Scope: Please list the objectives and/or scope of the proposed paper. (25–75 words) The intent of this paper is to recognize and address the challenges that downstream companies face across their value chain including a history of having siloed businesses processes that have created ‘value leaks’. We propose an unified operations management approach that orchestrates all activities across the value chain as part of an enterprise digital transformation strategy. Business process can be deeply transformed when operations, supply chain and process optimization are connected in a collaborative environment. Methods, Procedures, Process: Briefly explain your overall approach, including your methods, procedures and process. (75–100 words) Refineries are at different stages in their digital transformation journey and have built their business workflows over many years across multiple point solutions. We propose a digital transformation strategy for operations across five key characteristics, that is: Results, Observations, Conclusions: Please describe the results, observations and conclusions of the proposed paper. (100–200 words) Across a refinery's value chain there are significant benefits that can be realized by approaching digital transformation across their operations enabling end-to-end value chain optimization including: Novel/Additive Information: Please explain how this paper will present novel (new) or additive information to the existing body of literature that can be of benefit to and/or add to the state of knowledge in the petroleum industry. (25–75 words) This paper is novel as it takes a wholistic look at a refinery operations value chain and eliminating existing value leaks end-to-end. It recognizes how existing systems have been built-up on outdated technology and siloed business process and proposes a path forward bringing operations, supply chain and process optimization together as a key element of a digital transformation strategy. The paper also explores how AI & prescriptive models pave the future for optimization.
