Abstract:The aim of this project is to deliver a solution that models the tasks of the production planners at DS Smith Packaging B.V. located in Eerbeek, The Netherlands. In order to model the different tasks of the production planners, we use a modular approach. The solution consists of five modules: an order selection module, a cutting stock problem module, a corrugator scheduling module, a converting scheduling module, and a Pentek (buffer zone) module. For solving the corrugator scheduling problem we formulate three alternative approaches. The first approach uses a 1-Opt heuristic. This heuristic selects a random deckle solution and inserts it at another place. The second is a heuristic based on simulating annealing (SA) and the third heuristic is based on the adaptive search (AS). After each approach, we use an integrated corrugator and converting scheduling heuristic. Overall, this research has provided valuable insights that help DS Smith in improving their production planning and scheduling. This may lead to a decrease in waste and idle time of machines, and an increase in the on time delivery performance. This helps DS Smith in being more competitive in the market and to meet customer demands.
