This paper addresses the implementation of financial cross functional links with the enterprise value-added chain including retrofitting activities at plant level when scheduling, planning and budgeting in short term planning in batch process industries. The main idea is achieving financial-supply chain integration into advanced planning and schedule (APS) enterprise systems (Badell & Puigjaner (2001 a). Discover a powerful tool for scheduling in ERM systems. Hydrocarbon Processing, 80(3), 160; Badell & Puigjaner (2001b). Advanced enterprise resource management systems. Computers & Chemical Engineering, 25, 517). The platform built combines a deterministic cash flow management model with an advanced schedule algorithm using a MILP formulation. The modelling framework created can support the budgeting activity of the entire enterprise functionality, being now the budget the core document for enterprise management. The benefits of this work are shown through a case study that illustrates the modelling framework, the information flows and procedures necessary to implement a financial/supply chain scheduling methodology for the use of financial managers during planning and budgeting activities in process industries.
