Purpose For robot motion planning there exists a large number of different algorithms, each appropriate for a certain domain, and the right choice of planner depends on the specific use case. The purpose of this paper is to consider the application of bin picking and benchmark a set of motion planning algorithms to identify which are most suited in the given context. Design/methodology/approach The paper presents a selection of motion planning algorithms and defines benchmarks based on three different bin-picking scenarios. The evaluation is done based on a fixed set of tasks, which are planned and executed on a real and a simulated robot. Findings The benchmarking shows a clear difference between the planners and generally indicates that algorithms integrating optimization, despite longer planning time, perform better due to a faster execution. Originality/value The originality of this work lies in the selected set of planners and the specific choice of application. Most new planners are only compared to existing methods for specific applications chosen to demonstrate the advantages. However, with the specifics of another application, such as bin picking, it is not obvious which planner to choose.

Open Business Models

Purpose The purpose of this paper is to provide guidelines for practitioners in choosing the right response to potential threats by open business models. Design/methodology/approach The study focuses on identifying the dimensions of open business models. It consisted of 32 interviews with experts on open business models complemented by panel discussions with a selection of experts to validate the findings. Findings Five dimensions of open business models are identified: motivation, object, community, action and governance. Based on those dimensions, three responding strategies are proposed. Practical implications This paper offers insights for strategists and entrepreneurs who consider developing open business models or are attacked by competitors or other market players with open business models. Originality/value Complementing previous research, this paper highlights how the five dimensions of open business model can serve as a tool to design appropriate strategies when confronted with new forms of competition.

The Ideal

Purpose – The purpose of this paper is to evaluate expert systems (ES) for selection of material handling (MH) equipment on their use of information and generation of equipment, and provide guidelines that can enhance developing them in the future. Design/methodology/approach – Data envelopment analysis (DEA) is used to evaluate efficiency of ES on their use of information and generation of equipment. Characteristics of benchmark ES are identified to serve as guidelines in developing future ES. Findings – Results of DEA indicate that most ES use a large amount of information that does not commensurate with the number and variety of equipment they generate. Research limitations/implications – The ideal MH equipment for a situation is not known whether it is selected by ES or other procedures. Therefore, this study focusses on efficiency of ES in using information to generate MH equipment without regard to whether ES produce the right equipment for a situation or not. Practical implications – Developers of future ES should consider the efficiency of an ES in using information and generation of equipment, in addition to considering its functions and methodologies. They should utilize means similar to those employed by benchmark methodologies and other ones that can be thought of to economize information and generate more number and variety of equipment, and thus render ES more useful to facility designers and manufacturing managers. Originality/value – The paper presents the first evaluation of ES for selection of MH equipment. The evaluation performed should enhance development of future ES in this field, and can be extended to ES in other application domains.

Practical Implications

Purpose The Immigration Act (2014) at Part 3 established a new regime with private landlords incurring penalties (and potentially criminal liability from 1 November 2016) if they allow a person disqualified, by reason of migration status, to reside in a property as their only or main home. Known colloquially as the “right to rent”, the provisions restrict access to accommodation and impose onerous duties on landlords to check tenants’ migration status. The purpose of this paper is to consider how a change in the emphasis of regulation introduced by the provisions, resulted in the coalescence of opposition by landlords and renters in a way that historically would have been unthinkable. Design/methodology/approach Using the lens of Foucault’s governmentality, it is possible to see how Government sought to shift the locus of control from itself to the landlord, which through its legislative and policy stance resulted in such fierce opposition as evidenced by the first instance challenge to the provisions in R (Joint Council for the Welfare of Immigrants) v SS for the Home Department [2019] EWHC 452 (Admin). Findings The focus of regulation introduced by the provisions resulted in the coalescence of opposition by landlords and renters in a way that historically would have been unthinkable. Landlords and renters are usually thought of as being in opposition, but not so here. This may offer hope for more productive regulatory outcomes where both parties work together. It may also suggest that encroaching on the notion of private rights and interests in law could result in counterproductive consequences. Research limitations/implications Unlike Foucault’s notion of surveillance and control, governmentality shifts the emphasis from a hierarchical conception of government to practices including self (imposed) governance – with here, the landlord being required to act as a proxy for border agents. This suggests that there may exist boundaries beyond which, in a given context, it might be unwise for Government to step without adverse consequences. Foucault’s ideas provide a starting point, but do not give us all of the answers. Practical implications The coalescence of opposing actors can be a significant force to challenge government given the extent of their knowledge of the given context. It may also suggest a route to a more collaborative form of regulation. Originality/value A novel theoretical take on an issue of concern raised by practitioners and interest groups alike.

Purpose – This paper investigates the determinants of credit card use and misuse by student and young professionals. Critical to the research is the impact of materialism and knowledge on selection of the appropriate credit card. Design/methodology/approach – This study uses survey research and partial least squares to investigate credit card behaviors of students versus young professionals. Findings – In a comparative study of young professionals and students, it was found that consumer knowledge, as expected, leads to better consumer selection of credit cards. Materialism was also found to increase the motivation for more optimal consumer outcomes. For more experienced consumers, such as young professionals, it was found that despite them being more knowledgeable, they were more likely to select a credit card based on impulse. Originality/value – This paper examines how materialism may in fact encourage some consumers to make better decisions because they are more motivated to develop better knowledge. It also shows how better credit card selection may inhibit impulse purchasing.

PurposeWaqf (endowment) lands constitute as among the highest types of waqf (endowment) properties in Malaysia; yet it is still unable to reach its maximum potential due to various challenges such as capital, location, legal and administrative issues. Therefore, this study intends to explore these issues by focussing on the two states in Malaysia (Selangor and Perak) that have fertile lands but different management authorities.Design/methodology/approachThere were series of interviews that had been conducted with ten (10) key informants who are experts and practitioners in the areas of Shariah (Islamic law), farming, agribusiness, land management and waqf.FindingsFindings exhibit that constraints and challenges that had been highlighted in the previous literature still exist (although some improvements had been made), but there is emerging theme that the study intends to highlight which is on the needs to secure market for the agribusiness produce and the potential role of anchor company in the agribusiness. It is pertinent that for agribusiness to thrive, selecting the right anchor company that has the capacity to address the challenges is necessary. This study posits two anchor company models (Waqf Trustee-Anchor Company and Waqf Trustee-Anchor Company-Community Farmers) that can be applied for agribusiness on the waqf lands.Research limitations/implicationsThis study is based on the Malaysia's context influenced by specific country's features. Nevertheless, such findings can still be used as reference or benchmark by other endowment trustees in other countries especially for the Muslim countries as well as the non-Muslim countries that have significant Muslim populations.Social implicationsThe suggested models have potentials to improve the living condition of the B40 (below 40% household income) in Malaysia because the models encourage their participation in the agribusiness activities.Originality/valueThis study focusses on the agribusiness, which is rarely being given attention in previous literature in the context of endowment lands. Therefore, this article bridges the literature gap and at the same time attempts to provide suggestion to address the pertinent issue – the underutilised endowment lands.

Purpose The purpose of this paper is to evaluate the model of a rear pressure bulkhead with different design optimizations to meet the pressurized cabin requirements of an aircraft. Design/methodology/approach This paper presents the results of the static analysis of a dome-shaped rear pressure bulkhead model designed in Catia-v5. Numerical analysis of model meshed in hyper-mesh and solved using Opti-Struct for iterative design optimizations. Findings All the iterative models are analyzed at 9 Psi. Rear pressure bulkhead designed with L-section stringer shows better results than the model optimized with T-section stringer for the same thickness. The model optimized with L-shaped stinger also reduces the weight of the bulkhead without affecting the structural integrity. Practical implications It has been concluded in this paper that the selection of specific shapes of the stringers shows a significant influence on weight reduction. Originality/value This paper provides a topical, technical insight into the design and development of a rear pressure bulkhead. It also outlines the future development of dome-shaped rear pressure bulkhead.

PurposeThe quest to discover optimal conditions or amounts has been carried out in many scientific disciplines and practical fields. In astrophysics, biology, medicine, psychology and education, the quest has resulted in finding the right amount of something, a desirable middle between extremes, a balance between conditions or the optimal state of a system. The results are referred to as the Goldilocks principle, which is based on the idea of being “just right”. The aim of our study was to find out if there are any measures in information search that could be identified as Goldilocks ranges.Design/methodology/approachWe conducted a user experiment in which 68 participants carried out a time-unlimited, topical search task involving finding relevant websites on the basis of which the participants were supposed to prepare a presentation on a given topic. We examined aspects of their search behavior.FindingsWe found that information search Goldilocks ranges can be identified for a length of a search session, number of relevant results, number of queries submitted and number of search engine results pages (SERPs) visited. This preliminary study has resulted in indicating the following dominant ranges: Number of relevant documents found: 5–8; Time spent searching: 21–35 min; Number of queries submitted: 3–7; Number of SERPs viewed: 1–3.Originality/valueTill now, no one has studied Goldilocks ranges in information retrieval. The Goldilocks ranges have some practical implications for improving the effectiveness of web searching.

PurposeThe purpose of this paper is to demonstrate a “maintenance pathway” for ensuring a low false negative rate in closing investigations unlikely to lead to a clearance (detection).Design/methodology/approachA randomised controlled experiment testing solvability factors for non-domestic cases of minor violence.FindingsA random selection of 788 cases, of which 428 would have been screened out, were sent forward for full investigation. The number of cases actually detected was 22. A total of 19 of these were from the 360 recommended for allocation. This represents an improvement of accuracy over the original tests of the model three years earlier.Research limitations/implicationsThis study shows how the safety of an investigative triage tool can be checked on a continuous basis for accuracy in predicting the cases unlikely to be solved if referred for full investigations.Practical implicationsThis safety check pathway means that many more cases can be closed after preliminary investigations, thus saving substantial time for working on cases more likely to yield a detection if sufficient time is put into the cases.Social implicationsMore offenders may be caught and brought to justice by using triage with a safety backstop for accurate forecasting.Originality/valueThis is the first published study of a maintenance pathway based on a random selection of cases that would otherwise not have been investigated. If widely applied, it could yield far greater time for police to pursue high-harm, serious violence.

Purpose By examining my personal development and career trajectory, I hope to share some insights into life as an academic. My particular path has contained, as most paths do, twists and turns. As I look back, they all seem somehow related to each other, but they were not all planned. Design/methodology/approach I will discuss my life and career in chronological order, then reflect on my career and research philosophy. I will also discuss several of my most cited articles and how they emerged. Findings I emphasize research that is both academically rigorous and relevant to business. I also show that passion for a subject, even one that is risky and not encouraged by others, has resulted in lifelong interest and inspiration for me. While not appropriate for all because of the risk, I found it worth taking a chance, largely because I was highly inspired by the subject. Practical implications Research that is programmatic has benefits because it allows a scholar to own an area. Also, working with the right co-author teams – sometimes ones where different talents are distributed across the team is effective. Originality/value The story and opinions are mine alone.
