The LNG major needed to address one tactical and two operational challenges. One was to do with planning and scheduling, and the other two were to do with voyage management and terminal operations. They did not have an efficient tool to manage complex planning and scheduling that involved creation of production and delivery plans for all products. The planning and scheduling was needed to manage the supply chain, storage and loading facilities. It took them 75 days to prepare annual delivery plans using spreadsheets for data compilation and the more than 2-month timeframe was detrimental to their annual tactical plan execution.
