Abstract
Purpose
During design of reconfigurable manufacturing systems, manufacturing companies need to select and implement the right enablers of reconfigurability in accordance with the specific requirements being present in the manufacturing setting. Therefore, the purpose of this paper is to investigate enablers of reconfigurability in terms of their importance in industry, current level of implementation in industry, and significant differences in their implementation and criticality across different manufacturing settings.
Design/methodology/approach
A questionnaire survey is conducted, in order to provide generalizable empirical evidence across various industries and manufacturing types.
Findings
The findings indicate that the level of implementation of the reconfigurability enablers is rudimentary, while their criticality is perceived higher than the current level of implementation. Moreover, significant differences regarding implementation and criticality of mobility, scalability, and convertibility were found for companies with varying degrees of manual work, make-to-stock production, and varying production volume, industry type and organization size.
Research limitations/implications
Main limitations of the research cover the relatively small sample size and non-random sampling method applied, primarily limited to one country, which could be increased to further extent the findings reported in this paper.
Practical implications
The findings indicate that the importance and implementation of reconfigurability enablers is contingent on the manufacturing setting. Thus, the research presented in this paper provides valuable knowledge in regard to aiding a paradigm shift in industry and help companies design manufacturing systems with the right reconfigurability enablers.
Originality/value
This paper expands research on manufacturing system design for changeability and reconfigurability, by explicitly considering these as capabilities that can be enabled in various ways for various purposes in different manufacturing contexts.

Abstract
Purpose
The purpose of this paper is to present a decisions support tool that can be applied in initial stages of design, for evaluating the investment feasibility of changeable and reconfigurable manufacturing design concepts, based on future demand predictions and their uncertainties. A quantitative model is proposed, which evaluates the discounted value of capital and operating costs of changeable manufacturing design concepts, based on essential characteristics regarding their type and extent of changeability.
Design/methodology/approach
Quantitative empirical modeling is applied, where model conceptualization, validation, and implementation are central elements, using two Danish manufacturing companies as cases.
Findings
The applicability of the model is demonstrated in the two case companies, highlighting differences in type, extent, and level of feasible changeability, as a result of differences in product and production characteristics.
Research limitations/implications
Further studies of changeability implementation should be conducted across industrial fields in order to generalize findings.
Practical implications
There is currently limited support for the conceptual design phase of changeable and reconfigurable manufacturing, where critical decisions regarding type, extent, and level of changeability must be made, regardless of high degrees of uncertainty about future demand scenarios.
Originality/value
This paper expands previous research on design for changeability and reconfigurability, by explicitly considering changeability as a capability that can be enabled in various ways for various purposes in different industrial contexts. The proposed model and the case implementations provide important knowledge on the transition toward changeability in industry.

Abstract
Purpose
The purpose of this paper is to investigate how necessary changes in a manufacturing system can be determined based on a new product specification. It proposes a formal modelling approach, enhancing the utilization of changeability of a manufacturing system given a set of changes in a product.
Design/methodology/approach
To develop the proposed modelling approach, a design science research method is used to iteratively frame an issue, develop a solution and evaluate it in a relevant environment. Evaluation is carried out through a case study.
Findings
A stepwise method is introduced, facilitating the creation of a model describing the relations between product characteristics within a product family and the changeability of a manufacturing system. Limitations of each manufacturing system module are evaluated to determine permittable changes in the product domain. This establishes clear relations between product attributes and manufacturing capabilities. Through this, users receive feedback on which parts of the manufacturing system must change, depending on changes in product attributes.
Research limitations/implications
Testing has been carried out in an academic learning factory setting. Products and processes are thus less complicated than an industrial setting. The system used for validation is highly modular by design.
Practical implications
The proposed approach could be used during product development, when determining characteristics and variety of new products, evaluating the consequences of changing the solution space. This implies a shorter time-to-market and lower product costs.
Social implications
Faster product development and shorter time-to-market would give manufacturers increased agility to track market needs, and ultimately lead to greater fulfilment of customer requirements.
Originality/value
The current body of literature focus on modelling either products or manufacturing systems. Little literature addresses both, but does not touch on identifying changes within parts of the manufacturing system, nor supports the high changeability proposed in this research.

Abstract
Purpose
The purpose of this research is to identify the crucial barriers to the implementation of mass customization (MC) in Indian SMEs and to investigate the interactions among them so that important managerial implications could be formulated to facilitate the implementation of MC in SMEs.
Design/methodology/approach
The contextual relationships and hierarchies of the barriers are established through the interpretive structural modelling (ISM) approach, and MICMAC analysis has been used to classify the barriers into different groups. Further, structural equation modelling based on partial least squares (PLS-SEM) has been applied to statistically validate the ISM model using the data collected through a questionnaire-based survey of Indian organizations.
Findings
A portfolio of barriers, containing 16 items, has been identified from the literature review and a series of semi-structured interviews of practitioners. The study develops a structural model by establishing relationships and imposing directions among the barriers and classifies the barriers according to their driving and dependence power to serve as a roadmap for SMEs willing to implement MC into practice.
Practical implications
The study highlights the critical barriers which have a significant impact on other barriers and need to be handled at priority. Also, the present research renders insights to SMEs to better prioritize their efforts and resources to overcome these barriers.
Originality/value
This research happens to be first in the MC literature that investigates the key barriers responsible for hindering the implementation of MC in SMEs and develops a statistically validated contextual model showing hierarchies and relationships of the barriers.
