Abstract

Presents a study which explored a relationship between production process focus and performance at the business unit level using the profit impact of marketing strategies (PIMS) database. The relationship between production process focus and financial performance for business units was partially supported using return‐on‐sales (ROS), and was not supported with return‐on‐assets and return‐on‐income. Indicates that the degree of production process focus is not directly related to a business unit′s performance. The implication is that the degree of production process focus must be recognized as part of a manufacturing strategy that is consistent with an overall business strategy.

Abstract

Discusses the variety of production control situations within process industries. Following a literature review, a typology is introduced which discriminates between two extreme types of process industries: batch/mix and process/flow businesses. Reviews the research in production and inventory control in each of the extreme types. Identifies a control framework for operations management in process/flow businesses. Notes that although detailed scheduling approaches for batch/mix businesses exist, a control framework for the latter is missing. Concludes that operations management in batch process industries needs considerable research attention.

Abstract

Purpose

Assembly line is a common production form and has been effectively used in many industries, but the imprecise processing time of each process makes production line balancing and capacity forecasting the most troublesome problems for production managers. In this paper, uncertain man-hours are represented as interval grey numbers, and the optimization problem of production line balance in the case of interval grey man-hours is studied to better evaluate the production line capacity.

Design/methodology/approach

First, this paper constructs the basic model of assembly line balance optimization for the single-product scenario, and on this basis constructs an assembly line balance optimization model under the multi-product scenario with the objective function of maximizing the weighted greyscale production line balance rate, second, this paper designs a simulated annealing algorithm to solve problem. A neighborhood search strategy is proposed, based on assembly line balance optimization, an assembly line capacity evaluation method with interval grey man-hour characteristics is designed.

Findings

This paper provides a production line balance optimization scheme with uncertain processing time for multi-product scenarios and designs a capacity evaluation method to provide managers with scientific management strategies so that decision-makers can scientifically solve the problems that the company's design production line is quite different from the actual production situation.

Originality/value

There are few literary studies on combining interval grey number with assembly line balance optimization. Therefore, this paper makes an important contribution in this regard.

Abstract

Purpose

A robust description of the material transformation system is fundamental for understanding its capabilities and thus for communicating, prioritising and changing the system. Deploying a previously developed configuration model the purpose of this paper is to test the industrial usability of the model as an instrument to gain a better understanding of the material transformation system through externalising the generic production capabilities of the system.

Design/methodology/approach

In a multiple case study approach and using a prior conceptual configuration model of the material transformation system in the process industries as a research instrument, company-generic production capabilities were investigated in three companies representing the mineral, food and steel industries.

Findings

The empirical results supported the utility of the model as an instrument in providing a coherent set of elements that define operations and thus serve as a platform to model company-generic production capabilities and serve as input to strategizing though implicating needed change to the material transformation system. The theoretical contribution was mainly the empirical validation of the previously developed conceptual model as a tool in knowledge formation of the capabilities of the system and to outline the concept of “production capabilities configuration”.

Research limitations/implications

Three sectors of the process industries were studied but it is recommended that the results should be replicated in complementary case studies or a survey of larger samples from the process industries. Those studies should not only be limited to increase the empirical knowledge base, but possibly to identify additional new variables, further refine the set of variables in the present model and investigate their relationships.

Practical implications

It is argued that the model can already be used as a tool to support both horizontal and vertical communication on production capabilities, thus facilitating, e.g. manufacturing strategy development.

Originality/value

The validated conceptual model supported by the empirical evidence is new knowledge to be used in the analysis of company-generic production capabilities in the process industries.

Abstract

Purpose

This paper focuses on the determination of the cost completion rate used to calculate the equivalent units of production in a continuous process costing system. The paper aims at two research questions. What procedures do companies utilize in practical terms? How should the completion level percentage be calculated conceptually?

Design/methodology/approach

The study is a qualitative exploratory survey. The companies targeted were those noted in “Melhores e Maiores,” a ranking of the best and biggest Brazilian companies. A total of 175 questionnaires were sent to pre‐selected enterprises, each with revenues of more than US$100 million per year, and 50 usable responses were returned.

Findings

A literature review of the theoretical procedures used for continuous process costing revealed no indication of an objective method for determining the completion level. The empirical research in the present study confirmed that, in practice, companies do not adopt the general procedures proposed by the theory. The best practices applied by the companies have been shown to be an adequate alternative, because the results are identical to those obtained with the proposed method.

Research limitations/implications

The study bears the usual limitations of a qualitative exploratory survey regarding its generalization to other companies.

Originality/value

The originality of the study is based on the assumption that cost accounting theory does not offer an objective solution for the computation of the completion level percentage and, consequently, that companies in continuous process production system do not adopt the theoretical concepts with respect to inventory evaluation of goods‐in‐process and finished goods.

Abstract

Purpose

While localized small-series production is a significant opportunity, various tensions challenge implementation in high-cost contexts. This paper explores how managers view and respond to different tensions in small-series production implementation by adopting a paradox-based perspective.

Design/methodology/approach

The paper presents a multiple case study addressing small-series production within EU's apparel industry, as key context to address managerial awareness, and responses to tensions regarding location and supply network configuration decisions. Seven cases were selected for variation in customization and implementation (early/established), ownership, location and company size, to identity commonalities.

Findings

The study highlights performing tensions related to sustainability, and risk, in addition to confirming traditional goal-related tensions predominantly impacting small volume production. With on-demand/custom production, tensions include costs in conflict with process scale, and several process-related tensions (flexibility, expansion/development, risk management). Identified multidimensional responses do not include location or structural decisions, instead focusing on synthesis, through product-operations efficiency, knowledge development and process innovation and supply chain collaboration. Temporal separation is found with customization, including reducing product/process complexity short-term with enhancing process development, which suggests latent learning tensions and limited awareness.

Research limitations/implications

Future research should address the extent to which tensions can be resolved or remain paradoxical, as well as dynamic decision-making and latent tensions.

Originality/value

The paper shows how paradox theory facilitates a deeper understanding of complex network configuration decisions, including reshoring/localization. The findings identify organizing tensions/elements and elaborate upon performing/performing-organizing tensions suggested with small-series production, location decisions and supply chain management.

Abstract

Overview All organisations are, in one sense or another, involved in operations; an activity implying transformation or transfer. The major portion of the body of knowledge concerning operations relates to production in manufacturing industry but, increasingly, similar problems are to be found confronting managers in service industry. It is only in the last decade or so that new technology, involving, in particular, the computer, has encouraged an integrated view to be taken of the total business. This has led to greater recognition being given to the strategic potential of the operations function. In order to provide greater insight into operations a number of classifications have been proposed. One of these, which places operations into categories termed factory, job shop, mass service and professional service, is examined. The elements of operations management are introduced under the headings of product, plant, process, procedures and people.

Abstract

Purpose

The purpose of this paper is to redesign the layout of production floor by considering lean manufacturing in order to eliminate the waste and using Block Layout Overview with Layout Planning (BLOCPLAN) algorithm to attain new layout of facilities in Indonesian home-food industry.

Design/methodology/approach

The common problems that might be appearing in home-food industry, especially in the developing countries like Indonesia are unstandardized production process and unorganized work environment which could produce the waste. One of many solutions to handle this problem is improving the work area (work station) in production floor by rearranging and designing standard operating procedure (SOP) by using lean manufacturing concept. The initial data to minimize the waste is motion time study (data) to identify production standard time. The next step is identifying the common waste(s). Meanwhile, the production floor layout used in this research is designed by using BLOCPLAN algorithm.

Findings

The recommendation of shop floor facility layout is based on identified waste, which is excess transportation. Subsequently, standard operational procedure (SOP) is developed to support the recommended facility layout as the reference for cookie production process so it can minimize the waste.

Research limitations/implications

Lean concept is one of method that is widely implemented to reduce the occurrence of defective products and waste that do not provide added value. Based on previous researches, it was found that the concept of lean manufacturing can be applied in various types of service and manufacturing industries, both large companies and small and medium enterprises. Home-food industry competition nowadays is getting intense. This condition makes the stakeholders (of home-food industry, especially in Indonesia) need high performance and productivity to keep their business stable in winning the competition. The new layout can reduce the disadvantages of actual condition.

Practical implications

This research is useful for small- and medium-sized enterprises (SMEs) in Indonesia especially for home-food industry. The BLOCPLAN layout (as the recommendation) has displacement moment with reduction of 40 percent.

Social implications

This research believed that it can help SMEs improve their productivity in producing cake and cookies in terms of better layout which can reduce worker movement and standardized working procedure. The design of the production facility layout is a method used to rearrange the production process area so that the distance between processes can be minimized. SOPs was provided as the direction and supervision of workers to work according to standards.

Originality/value

SOP design can support recommended layout as the reference on making the cake (product) to eliminate wastes, which are motion/movement (alternating in production process flow) and long waiting time due to process delays.

Abstract

Purpose

The materials planning (MP) environment sets the prerequisites for the MP process. Before and during production transfer and start-up (PTS) supply chain uncertainty of the MP environment increases, as the company goes from a known to an unknown situation. The purpose of this paper is to describe the impact of the MP environment on the MP process before and during PTS.

Design/methodology/approach

A conceptual framework describing the MP environment before and during PTS is developed and applied to one case of outsourcing from Sweden to China. The framework is based on a literature review and further evaluated by both researchers and managers.

Findings

A conceptual framework describing the dynamic MP environment before and during PTS has been developed compared to previously static MP environments descriptions. In addition, this framework proved to be useful in analysing the importance of various characteristics of the MP environment before and during PTS.

Practical implications

The study highlights the importance of a proactive approach to materials availability when transferring production. The conceptual framework developed here can be used as a checklist to identify the characteristics of the MP environment that are most important to ensuring materials availability.

Originality/value

The paper highlights the PTS when outsourcing, a substantial time frame with a large impact on success. This is an important contribution, given the focus of previous outsourcing research on strategic issues. Further, the paper demonstrates the differences between static and dynamic MP environments.
