Decision support for production localization : Process, activities and localization factors
- 2013
-
Konferensbidrag (refereegranskat)abstract
- Traditional production location decisions are mainly based upon economic factors while factors that facilitate decision makers in selecting the most suitable production location in terms of operations performance are rarely considered. Therefore, this paper presents a developed decision support for production localization that emphasises operational factors to be considered in the decision making. The research methodology combines a literature study with a multiple case study method. The findings are synthesised into a five phase decision process for making production localization decisions in practice. For each of these phases, key activities with related tools and expected output are developed.

- Decision are commonly based on the available or easily accessible information; this is also true for more complex assessments like production localization. Where to locate production is often a key strategic decisions that has great impact on a company’s profitability for a long time; insufficient business intelligence may therefore have grave consequences. Six production localization factor studies have been assessed to see if they are focusing on the same issues and if there are any gaps. A new approach for structuring localization factors and the localization process is then presented and assessed with regards to some previously identified critical issues.

In search for improved decision making on manufacturing footprint: A conceptual model for information handling
- 2011

Konferensbidrag (refereegranskat)abstract
- The footprint strategy of a manufacturing company is frequently highlighted as a key aspect to the company’s competitive advantage. However, research concerning international location decisions is limited. A comprehensive strategy has to function in a world with limited resources and continuous change of values. The purpose of this paper is to propose a conceptual model of the process for efficient production localisation decisions by integrating aspects influencing the design of the manufacturing footprint. Research on drivers for location of manufacturing emphasise input factors, market factors and technological knowhow as key factors. Looking at the entire industrial system, earlier research also illustrates the broad range of roles for the manufacturing plant within a company’s industrial system. Based upon this discussion of the motive for manufacturing location and the strategic role of the manufacturing plant, a conceptual model is introduced emphasising different levels that should be considered during the process of preparing a localisation decision. It serves as a base for more detailed studies on specific aspects, models and factors for manufacturing footprint analysis.

On the production location decision : A case study on process and criteria
- 2014
-
Ingår i: International Journal of Manufacturing Research. - 1750-0591. ; 9:1, s. 74-91
-
Tidskriftsartikel (refereegranskat)abstract
- The paper explores the process and criteria used in production location decisions, based on a literature overview and a case study in a Swedish manufacturing company with a global production network. The data collection comprised interviews with top management and project management as well as a document analysis. The findings indicate that the production location decision process is facilitated by following a stepwise process with an initial strategic analysis with a broad scope including also the selection of the future production system concept.

- Production control mechanisms have been broadly investigated by researchers, where each type of production control mechanism has different performance depending on the situation. However, the situation with high variety products in a divergent production line has been rarely studied. This paper presents a study on the applicability of four different production control mechanism; three different variants of POLCA as well as one type of CONWIP control in an automotive production company with high variety of products and divergent line. ExtendSim simulation software has been used for discrete event simulation in order to analyse the production line and compare strategies. The main criteria for comparing the performance were throughput, shop floor throughput time and level of work in process (WIP). The study shows that m-CONWIP (as a variant of CONWIP) is recommended in this situation, as it leads to more reduction in WIP amount and throughput time, while throughput value does not drop.

Production control mechanisms and POLCA performance in a divergent production line
- 2012

Tidskriftsartikel (refereegranskat)abstract
- Production control mechanism is a critical element in today’s production situation, where production systems compete on quick response and resource efficiency. The purpose of a production control mechanism is to define the best time to release material and orders. POLCA as a simple production control mechanism that in one hand tries to reduce throughput time and on the other hand helps manager to control work-in-process inventory. In addition to reviewing the history of the production control mechanism and looking into some of them, the paper classify production control mechanisms in different categories and studies more specifically a POLCA system performance in a divergent production line situation with long changeover time in the supplier cell (the shared cell which has to supply different routes). It is concluded that the best form of POLCA in a divergent production line is to push material in the first stage without any limit and then control and limit it in the second stage.

Production control mechanisms in a convergent production line

- One of the critical elements that managers face in manufacturing companies is to find an appropriate Production Control Mechanism (PCM) for their shop floor. There are many different PCMs and each of them has different performance depending on the situation. A convergent production line is a situation that rarely has been studied from this perspective. This study compares three kind of PCM that are identified as suitable for such a complex production line: POLCA, CONWIP and m-CONWIP. Extendsim simulation software was employed for discrete event simulation in order to compare performance of the considered PCMs in a convergent production line producing one type of product. The results indicate that the studied PCMs show distinct different performance in the various configurations of the convergent production line. The simulation shows (a bit surprisingly) that POLCA has the best performance in the considered situation and m-CONWIP has the worst performance. However, in an even more complex situation with more product types, the performance of POLCA would be under question. The study complements previous studies on PCM applicability and configuration, and has a strong industrial implication for the increased emphasis on decision support for operations management in a resource efficient production setting.
