Comparison between rule- and optimization-based workload control concepts: a simulation optimization approach
Stefan Haeussler,Pia Netzer +1 more
36
TL;DR: Two of the most widely used and considered best performing periodic order release models out of both streams are compared: the LUMS (rule based) and the clearing function model (optimisation based).

Order release planning with predictive lead times: a machine learning approach
TL;DR: A flow time estimation procedure to set lead times dynamically using an artificial neural network is presented and it is shown that the proposed model using artificial neural networks outperforms the other tested approaches, especially for scenarios with high utilisation and high variability in processing times.

A two-level optimisation-simulation method for production planning and scheduling: the industrial case of a human–robot collaborative assembly line
Miguel Vieira,Samuel Moniz,Bruno Gonçalves,Tânia Pinto-Varela,Ana Paula Barbosa-Póvoa,Pedro Neto +5 more
TL;DR: A novel optimisation-simulation methodology based on the Recursive Optimisation-Simulation Approach (ROSA) methodology is developed to provide effective decision-support for integrated production decisions.

Comparison of two optimization based order release models with fixed and variable lead times.
TL;DR: It is shown that the clearing function model outperforms the input output control model in all scenarios by yielding lower inventory levels with shorter shop floor throughput times and the IOC model narrows the gap when using near optimal parameters especially for a scenario with deterministic demand.

Rule Based Workload Control in Semiconductor Manufacturing Revisited
Philipp Neuner,Stefan Haeussler +1 more
TL;DR: An essential task in manufacturing planning and control is to determine when to release orders to the shop floor, and a prominent approach is the workload control (WLC) concept.

Order review and release in make-to-order flow shops: analysis and design of new methods
TL;DR: Simulation results demonstrate that performance in pure flow shops can be strongly improved by applying the right combination of workload measures, load balancing, and order dispatching, and show that shortest processing time dispatching is highly effective in flow shops as it avoids starvation of stations.

Load-Oriented Manufacturing Control
Hans-Peter Wiendahl
- 19 Dec 1994
TL;DR: In this paper, a general, realistic model of the manufacturing process is presented, along with a Load-Oriented Order Release (LOOR) and a schedule-oriented capacity planning and control.

Theory and practice of load-oriented manufacturing control
TL;DR: Load-oriented manufacturing control is a new solution for job shops and its successful implementation in a plastic leaves factory as mentioned in this paper, where the idea is to limit and balance work-in-process inventory on a level as low as possible in order to accomplish a high workcentre utilization as well as a rapid and in-time flow of orders.

The influence of shop characteristics on workload control
TL;DR: In this paper, a simulation study indicates that the relative performance of the traditional workload control methods changes completely with for instance the presence or absence of a dominant flow direction in the shop.
