Abstract
Title: Production Scheduling, a TOC approach.
Authors: Carl Andersson Alenbratt and Johan Knutsson.
Supervisors: Peter Berling, LTH and Anders Theander, SGSS.
Background: The problem of production scheduling is how to efficiently utilize available resources in order to both effectively and efficiently meet customer demand. In a modern manufacturing environment this is a very complex issue but it is at the same time absolutely fundamental for financial performance. The current production planning routine at the company is largely manual with the planning managers receiving only very basic support from the ERP system in place. SGSS feels that there may exist great improvement potential to unlock in this area.
Purpose: Investigate, model... (More)
Title: Production Scheduling, a TOC approach.
Authors: Carl Andersson Alenbratt and Johan Knutsson.

Background: The problem of production scheduling is how to efficiently utilize available resources in order to both effectively and efficiently meet customer demand. In a modern manufacturing environment this is a very complex issue but it is at the same time absolutely fundamental for financial performance. The current production planning routine at the company is largely manual with the planning managers receiving only very basic support from the ERP system in place. SGSS feels that there may exist great improvement potential to unlock in this area.
Purpose: Investigate, model and analyze the current scheduling routine and how it should be modified to improve production performance.
Methodology: The research design is a case study. The analysis procedure is influenced by the management philosophy “Theory of constraints” and this is mainly manifested through the identification and exploitation of the constrained resource in production. The actual analysis of how scheduling, with respect to the constrained resource, influences performance is primarily done using a simulation model over the production environment. The scrutinized decision parameters are batch size, sequence and planned lead time through production.
Conclusions: The simulation results indicated great improvement potential in how the planned lead times are currently set as well as showed that the batch size selection guidelines were neither necessary nor optimal in terms of performance. However, the grouping of similar products to achieve a set-up efficient sequence was, within reasonable bounds, not seen as crucial for meeting current throughput targets. Instead, more of the sequencing effort should be placed on keeping cycle times low.
Keywords: production scheduling, theory of constraints, batch size, lead times, simulation, service level, case study. (Less)
