Advanced Planning and Scheduling (APS) systems are argued to provide a number of positive effects when implemented in manufacturing firms, e.g. in terms of planning performance, cost performance, supply chain visibility. The purpose of this paper is to analyse the effects from implementing and using APS systems for supply chain planning, in terms of both experienced benefits and problems, and type of planning context.
Our research is based on a multiple case study, where 5 manufacturing firms that recently have implemented APS systems to support tactical planning processes (e.g. sales and operations planning and multi-site master planning), have been studied. Case data (interviews, meetings, performance data, etc.) have been collected during four years. Pattern matching and logical models are used in the cross-case analysis.
The results show differences in APS effects depending on what type of implementation focus and APS use that have been employed. Results also show that the supply chain context (organisation, individuals, technology) affects the APS effects.
These results can be used on the one hand in further research to establish a typology of different ways to implement and use APS systems, and on the other by managers in choosing the right APS approach depending on what effects that they are striving for.
There are few accounts in academic research on the practical use of APS systems and their effects on the planning process and performance. This research provides such results.
