A recent Institute for Operations Research and the Management Sciences (INFORMS) Project is to preserve the origin of Operations research. To do that, INFORMS initiated Oral History project where they interviewed various individuals about the history of OR. One of the first individuals interviewed was Benjamin Lev.

== Selected contributions ==
=== Inventory Control Models ===
Classical inventory models assume fixed parameters. Lev and co-authors relaxed those requirements by allowing finite horizon models, price changes, holding cost changes, fixed costs changes. This work resulted in several publications in major journals. 
=== Transportation Problems ===
Classical transportation problems attempt to minimize distribution cost. It is counter intuitive that shipping more goods will result in lower distribution cost. Lev and co-authors worked on More-for-Less transportation problems as well as Fixed Charge Transportation problems. This effort resulted in several publications in major Operations Research journals.
=== DEA and Fuzzy ===
Since 2010 Lev has shifted much of his focus to DEA; Fuzzy; Multi-criteria Group Decision; Bi-level multi-objective problems. Lev and co-authors applied those techniques to numerous real-life problems mainly in China, such as water resources, banking, industrial parks, layouts, power dispatching, hospital scheduling, construction projects, portfolio selection and many others. Those research projects were published in several scientific journals.
