SEAS develops decision support tools and services based on advanced evaluation methodology. Proven over years in areas from procurement to urban and conservation planning, our unique approach has helped clients optimize decisions and explain their choices.

Who we are

We are decision support experts and inventors of a unique decision engineering framework – LSP. Developed and refined in practice by leading experts in the evaluation field, LSP powers all of our software tools and ranking engines. Based in San Francisco, SEAS’ team brings decades of decision support, software development and explainable AI expertise to complex evaluation situations.

What we do

We help clients reach optimal decisions. Our tools capture complex human decision logic, and reapply this logic to selection decisions. SEAS provides a full spectrum of advanced decision support tools and consulting services to augment customers’ domain expertise with decision logic expertise.

LSP Methodology

Our unique evaluation methodology — LSP (Logic Scoring of Preference) — uses graded logic to precisely and completely express the needs of stakeholders. With hundreds of sophisticated criterion functions and the power to handle tradeoffs and exceptions, LSP methodology offers a proven advantage over other methods in use today.


We offer a decision engineering framework aligned with explainable AI principles. Our software tools are based on sophisticated mathematical foundations and practice-tuned LSP methodology, published in top peer-reviewed journals and books.
