Abstract
Agent-based modeling has proven effective in increasing the understanding of complex systems, including social-economical systems. Agoal of modeling complex systems is to distill the system into simple agents with phenotypes guided by simple rules. The model then displays the emergent behavior of these agents interacting with each other and their environment. An agent-based model of innovation and its place in a global economy or ecosystem is presented. The model utilizes simple agents to represent innovating entities such as large corporations and small companies. The results produced by this model reveal the dynamics of innovation and its role in a global economy. The results indicate a large need for partnership in innovation for those entities working within rapidly changing domains. Domains, such as high technology, have constantly changing market expectations, which force innovating entities to seek external sources of assistance to meet these expectations in a timely enough fashion so as to incur benefit.

Abstract
Decision making in Flexible Manufacturing Systems (FMS) is difficult because of their high complexity level. The operational level of FMS is concerned with the detailed decision making required for real‐time operation. This applies to various control problems such as selection of a transportation path to move parts between stations. Describes a prototype knowledge‐based system for selection of a transport path in real‐time control of FMS. The knowledge‐based system is evaluated with an empirical approach.

Abstract
Many researchers in cybernetics remain sceptical about the practical applications of expert systems to industrial problems. Apart from the much publicised medical expert systems, little information is available about the use of these systems in such fields as safety and reliability. It was therefore encouraging to see the report in ESRA (European Safety and Reliability Association) Newsletter Vol. 5, No. 1, 1988, pp. 14, of experience with expert systems to perform safety studies. Work carried out in 1985 by Électricité de France (EDF) showed that an important step forward towards automating reliability systems could be taken by using expert systems.

Abstract
Purpose
With the current global downturn, companies must develop new and innovative approaches to ensure that economic sustainability is achieved. The purpose of this paper is to propose a Fit Manufacturing Framework (FMF), the adoption of which can help manufacturing companies to become economically sustainable and operate effectively in a global competitive market. This contribution extends the previous work by the authors and provides an evolution on the initial work through enhancing the development of Fit manufacture through developing a more robust framework and a more comprehensive functional testing of the framework.
Design/methodology/approach
The proposed FMF provides a new manufacturing management perspective and a new manufacturing management strategy for creating economically sustainable manufacturing organisations. It builds upon the principles of existing manufacturing paradigms, along with innovative management concepts, to set up the conditions necessary for sustainability. A pilot application of the framework in three SMEs shows positive initial results when assessed against four Measures of Performance.
Findings
Manufacturing strategies such as Lean and Agility allow companies to deliver bottom‐line savings in production terms, although their effectiveness depends upon the volume and demand profile of their products. The trend towards mass customisation requires companies to provide personalised products and services at mass production prices. This now places a further burden on companies and therefore a holistic manufacturing framework must be developed in order to ensure that the factory of the future is able to meet this new demand. This paper proposes a Fit manufacturing paradigm which integrates the manufacturing efficiencies achieved through Lean and Agility with the need to break into new markets through effective marketing and product innovation strategies to achieve long term economic sustainability. The small‐scale application of the approach in a case company shows the initial results to be positive when measured against key MOPs developed within this paper.
Originality/value
The development of a Fit paradigm aimed at tackling directly the issues of economic sustainability is proposed and is considered by the authors as one of a kind. Fit will also provide a framework for the implementation of sustainable manufacturing operations within organisations.

Abstract
Purpose
The purpose of this paper is to identify the qualitative characteristics that can make manufacturing small to medium‐sized enterprises (SMEs) more robust and hence become economically sustainable in this globally competitive environment. The characteristics identified will form the foundations for defining a new manufacturing management perspective to both academics and industrialists.
Design/methodology/approach
Through a comprehensive case study approach the authors initially analyse the developmental cycle of the subject company and then identify the key characteristics which enabled the company to become economically sustainable and survive in the changing environment in which it operates. The paper opens with a brief academic analysis of sustainability literature available, before developing the case study.
Findings
Traditional business improvement strategies, such as Lean and Agility, which many companies initially follow in an attempt to become more robust and economically stable, allow companies to deliver bottom‐line savings in production terms although their effectiveness depends upon the volume and demand profile of their products. Through the case study outlined in this paper however, a combined approach towards the application of Lean is outlined as a primary means of reducing operating costs alongside the simultaneous implementation of product innovation strategies which allows the company to break into new markets as a means to achieving long‐term economic sustainability and making it more robust to market changes. The development of a business within a business is described as an effective mechanism towards achieving business sustainability.
Research limitations/implications
The paper proposes a novel approach to achieving economic sustainability within a business and can be of benefit to the wider industrial and academic community. The development of work around a single company has its obvious limitations and it is crucial that further work, with a range of companies in the area of business sustainability, is key to developing a comprehensive set of sustainability characteristics.
Practical implications
The paper proposes a set of qualitative characteristics for the development of an economically sustainable manufacturing company. The development of a comprehensive case study with a subject company also directs and enables other companies of similar size and style to apply a similar approach and to achieve economic sustainability in an efficient and effective manner, through reducing production costs, minimising company failure and increasing business efficiency and effectiveness.
Originality/value
The development of a set of sustainability characteristics aimed at tackling directly the issues of economic sustainability is proposed and is considered by the authors as one of a kind. The case study approach also provides for a framework towards the implementation of sustainable manufacturing operations within SMEs.

Abstract
Purpose
This paper presents a review of the existing state-of-the-art literature on machine learning (ML) in logistics and supply chain management (LSCM) by analyzing the current literature, contemporary concepts, data and gaps and suggesting potential topics for future research.
Design/methodology/approach
A systematic/structured literature review in the subject discipline and a bibliometric analysis were organized. Information regarding industry involvement, geographic location, research design and methods, data analysis techniques, university, affiliation, publishers, authors, year of publications is documented. A wide collection of eight databases from 1994 to 2019 were explored using the keywords “Machine Learning” and “Logistics“, “Transportation” and “Supply Chain” in the title and/or abstract. A total of 110 articles were found, and information on a chain of variables was gathered.
Findings
Over the last few decades, the application of emerging technologies has attracted significant interest all around the world. Analysis of the collected data shows that only nine literature reviews have been published in this area. Further, key findings show that 53.8 per cent of publications were closely clustered on transportation and manufacturing industries and 54.7 per cent were centred on mathematical models and simulations. Neural network is applied in 22 papers as their exclusive algorithms. Finally, the main focuses of the current literature are on prediction and optimization, where detection is contributed by only seven articles.
Research limitations/implications
This review is limited to examining only academic sources available from Scopus, Elsevier, Web of Science, Emerald, JSTOR, SAGE, Springer, Taylor and Francis and Wiley which contain the words “Machine Learning” and “Logistics“, “Transportation” and “Supply Chain” in the title and/or abstract.
Originality/value
This paper provides a systematic insight into research trends in ML in both logistics and the supply chain.

The purpose of this paper is to propose a system dynamic simulated process model for maintenance work management incorporating the Fourth Industrial Revolution (4IR) technologies.
Abstract
Purpose
The purpose of this paper is to propose a system dynamic simulated process model for maintenance work management incorporating the Fourth Industrial Revolution (4IR) technologies.
Design/methodology/approach
The extant literature in physical assets maintenance depicts that poor maintenance management is predominantly because of a lack of a clearly defined maintenance work management process model, resulting in poor management of maintenance work. This paper solves this complex phenomenon using a combination of conceptual process modeling and system dynamics simulation incorporating 4IR technologies. A process for maintenance work management and its control actions on scheduled maintenance tasks versus unscheduled maintenance tasks is modeled, replicating real-world scenarios with a digital lens (4IR technologies) for predictive maintenance strategy.
Findings
A process for maintenance work management is thus modeled and simulated as a dynamic system. Post-model validation, this study reveals that the real-world maintenance work management process can be replicated using system dynamics modeling. The impact analysis of 4IR technologies on maintenance work management systems reveals that the implementation of 4IR technologies intensifies asset performance with an overall gain of 27.46%, yielding the best maintenance index. This study further reveals that the benefits of 4IR technologies positively impact equipment defect predictability before failure, thereby yielding a predictive maintenance strategy.
Research limitations/implications
The study focused on maintenance work management system without the consideration of other subsystems such as cost of maintenance, production dynamics, and supply chain management.
Practical implications
The maintenance real-world quantitative data is retrieved from two maintenance departments from company A, for a period of 24 months, representing years 2017 and 2018. The maintenance quantitative data retrieved represent six various types of equipment used at underground Mines. The maintenance management qualitative data (Organizational documents) in maintenance management are retrieved from company A and company B. Company A is a global mining industry, and company B is a global manufacturing industry. The reliability of the data used in the model validation have practical implications on how maintenance work management system behaves with the benefit of 4IR technologies' implementation.
Social implications
This research study yields an overall benefit in asset management, thereby intensifying asset performance. The expected learnings are intended to benefit future research in the physical asset management field of study and most important to the industry practitioners in physical asset management.
Originality/value
This paper provides for a model in which maintenance work and its dynamics is systematically managed. Uncontrollable corrective maintenance work increases the complexity of the overall maintenance work management. The use of a system dynamic model and simulation incorporating 4IR technologies adds value on the maintenance work management effectiveness.

Abstract
Purpose
This paper aims to provide a process-driven scientific data quality (DQ) monitoring framework by information product map (IP-Map) in identifying the root causes of poor DQ issues so as to assure the quality of scientific data.
Design/methodology/approach
First, a general scientific data life cycle model is constructed based on eight classical models and 37 researchers’ experience. Then, the IP-Map is constructed to visualize the scientific data manufacturing process. After that, the potential deficiencies that may arise and DQ issues are examined from the aspects of process and data stakeholders. Finally, the corresponding strategies for improving scientific DQ are put forward.
Findings
The scientific data manufacturing process and data stakeholders’ responsibilities could be clearly visualized by the IP-Map. The proposed process-driven framework is helpful in clarifying the root causes of DQ vulnerabilities in scientific data.
Research limitations/implications
As for the implications for researchers, the process-driven framework proposed in this paper provides a better understanding of scientific DQ issues during implementing a research project as well as providing a useful method to analyse those DQ issues based on IP-Map approach from the aspects of process and data stakeholders.
Practical implications
The process-driven framework is beneficial for the research institutions, scientific data management centres and researchers to better manage the scientific data manufacturing process and solve the scientific DQ issues.
Originality/value
This research proposes a general scientific data life cycle model and further provides a process-driven scientific DQ monitoring framework for identifying the root causes of poor data issues from the aspects of process and stakeholders which have been ignored by existing information technology-driven solutions. This study is likely to lead to an improved approach to assuring the scientific DQ and is applicable in different research fields.
