Multi-Criteria Flow-Shop Scheduling Optimization, Raviteja Arikati Jun 2017

Multi-Criteria Flow-Shop Scheduling Optimization, Raviteja Arikati

Industrial and Manufacturing Engineering

A flow-shop is a type of manufacturing job shop where similar jobs follow a similar, linear sequence through the shop. Every day, flow-shops receive several different orders and it is up to the scheduler to plan the daily schedule. This schedule should be designed to prevent bottlenecks in the shop, to have on-time delivery of products, and satisfy several other requirements. Often, schedulers perform subjective scheduling and utilize simple heuristics or just intuition to schedule the jobs. With computer-based scheduling, schedulers can now create schedules and determine quantitatively what sorts of schedules work best. Currently, much of the computer-based schedules …
