Improving the on-time delivery in manufacturing cells (English)
Abstract [en]

Purpose: On-time delivery is a concept that refers to the ability to deliver at agreed time. Several studies has shown that on-time delivery to customers is one of the most important competitive tools used by manufacturing enterprises. Internal on-time delivery is the ability to deliver between and within a company’s different sections at the right moment but is however a concept that is seldom being mentioned in research studies. The internal on-time delivery affects the external and is therefore an interesting subject to study. The purpose of this study is to increase the knowledge of how internal on-time delivery in make-to-order environments can be improved. Two research questions have been answered in order to fulfill the purpose:

1.      Which causes may affect the internal on-time delivery in make-to-order environments?

2.      How can the internal on-time delivery increase in make-to-order environments?

Methodology: A study with a qualitative approach has been used to fulfill the purpose and to answer the research questions. Common theories has been used in order to achieve a necessary knowledge about the subject. Theories about different tools for improvement has been used to answer the second question. Empirical data has been collected through a single case study in a manufacturing cell. The case study consisted of observations, interviews and a time study. The empirical data that has been collected describes the surveyed manufacturing cell, its product and its process.

Results: The first question has been answered with the use of collected empirical data and common theories. The found causes that affect the internal on-time delivery in make-to-order environments are: Enterprise resource planning systems does not portray real conditions, Priority control of manufacturing sequences is not being followed, Temporary bottlenecks occurs depending on mixed order entries, Cell layout can limit the control of the flow.

These causes has together with theories about different tools for improvement been used to answer the second question. Eight different types of improvements has been mentioned in the case. A few of these methods are: Enterprise resource planning should portray real conditions, The priority control of the manufacturing sequence should be followed, Resources capacity may need to be increased.

Discussion: It would be interesting if further research studies was made to gain more knowledge about causes that may affect the on-time delivery in make-to-order environments. It may be possible for manufacturing enterprises to use this studies structure to improve their own internal on-time delivery in make-to-order environments.
