Enhancing Erp System’S Functionality With Discrete Event Simulation, Young Moon, Dinar Phatak

Mechanical and Aerospace Engineering - All Scholarship

Purpose – To develop a methodology to augment enterprise resource planning (ERP) systems with the discrete event simulation’s inherent ability to handle the uncertainties.

Design/methodology/approach – The ERP system still contains and uses the material requirements planning (MRP) logic as its central planning function. As a result, the ERP system inherits a number of shortcomings associated with the MRP system, including unrealistic lead-time determination. The developed methodology employs bi-directional feedback between the non-stochastic ERP system and the discrete event simulation model until a set of converged lead times is determined.

Findings – An example of determining realistic production lead-time data …
