Abstract
Purpose
The after-sale service industry is estimated to contribute over 8 percent to the US GDP. For use in this considerably large service management industry, this article provides verification in the application of decision tree-based machine learning algorithms for optimal maintenance decision-making. The motivation for this research arose from discussions held with a large agricultural equipment manufacturing company interested in increasing the uptime of their expensive machinery and in helping their dealer network.
Design/methodology/approach
We propose a general strategy for the design of predictive maintenance systems using machine learning techniques. Then, we present a case study where multiple machine learning algorithms are applied to a particular example situation for an illustration of the proposed strategy and evaluation of its performance.
Findings
We found progressive improvements using such machine learning techniques in terms of accuracy in predictions of failure, demonstrating that the proposed strategy is successful.
Research limitations/implications
This approach is scalable to a wide variety of applications to aid in failure prediction. These approaches are generalizable to many systems irrespective of the underlying physics. Even though we focus on decision tree-based machine learning techniques in this study, the general design strategy proposed can be used with all other supervised learning techniques like neural networks, boosting algorithms, support vector machines, and statistical methods.
Practical implications
This approach is applicable to many different types of systems that require maintenance and repair decision-making. A case is provided for a cloud data storage provider. The methods described in the case can be used in any number of systems and industrial applications, making this a very scalable case for industry practitioners. This scalability is possible as the machine learning techniques learn the correspondence between machine conditions and outcome state irrespective of the underlying physics governing the systems.
Social implications
Sustainable systems and operations require allocating and utilizing resources efficiently and effectively. This approach can help asset managers decide how to sustainably allocate resources by increasing uptime and utilization for expensive equipment.
Originality/value
This is a novel application and case study for decision tree-based machine learning that will aid researchers in developing tools and techniques in this area as well as those working in the artificial intelligence and service management space.

This study examines whether managerial capability fit between line managers, middle managers and top-level managers enhances effectiveness.
Abstract
Purpose
This study examines whether managerial capability fit between line managers, middle managers and top-level managers enhances effectiveness.
Design/methodology/approach
Effectiveness data and managerial capability ratings from more than 1,600 manager–supervisor dyads were collected in the United States and Germany. Polynomial regression was used to study the relation between manager–supervisor fit and managerial effectiveness.
Findings
Our results indicate that the fit of managerial capabilities between a manager and his/her supervisor predicts the effectiveness of this manager. The most effective managers show particularly high managerial capabilities that are in line with predominantly high managerial capabilities of their supervisors. Two aspects are important: the manager–supervisor fit and the absolute capability level that both possess. The results further indicate that the importance of the manager–supervisor fit varies across lower, middle and top-level management dyads.
Research limitations/implications
This study contributes by advancing research on managerial capability fit conditions between managers and their supervisors as a central element in viewing and managing effectiveness.
Practical implications
This article informs managers, supervisors and HR professionals about pitfalls in organizations that degrade effectiveness.
Originality/value
This article shows how the alignment between managers and their supervisors relates to effectiveness in a large-scale study across different hierarchical levels.

This research fills a gap in process science by defining and explaining entropy and the increase of entropy in processes.
Abstract
Purpose
This research fills a gap in process science by defining and explaining entropy and the increase of entropy in processes.
Design/methodology/approach
This is a theoretical treatment that begins with a conceptual understanding of entropy in thermodynamics and information theory and extends it to the study of degradation and improvement in a transformation process.
Findings
A transformation process with three inputs: demand volume, throughput and product design, utilizes a system composed of processors, stores, configuration, human actors, stored data and controllers to provide a product. Elements of the system are aligned with the inputs and each other with a purpose to raise standard of living. Lack of alignment is entropy. Primary causes of increased entropy are changes in inputs and disordering of the system components. Secondary causes result from changes made to cope with the primary causes. Improvement and innovation reduce entropy by providing better alignments and new ways of aligning resources.
Originality/value
This is the first detailed theoretical treatment of entropy in a process science context.

Abstract
Purpose
Using a case study for electrical power equipment, the purpose of this paper is to investigate the importance of dependence between series-connected system components in maintenance decisions.
Design/methodology/approach
A continuous-time Markov decision model is formulated to find a minimum cost maintenance policy for a circuit breaker as an independent component while considering a downstream transformer as a dependent component. Maintenance of the dependent component is included implicitly in terms of the costs associated with certain state-action pairs. For policy and cost comparisons, a separate model is also formulated that considers only the circuit breaker as the independent component. After uniformizing the continuous-time models to discrete time, standard methods are used to solve for the average-cost-optimal policies of each model.
Findings
The optimal maintenance policy and its cost differ significantly depending on whether or not the dependent component is considered.
Research limitations/implications
Data used are from manufacturer databases; additional model validation could be conducted if applied to an electric utility asset fleet within their generation, transmission, and/or distribution system. This model and methodology are already being applied in other contexts such as industrial machinery and equipment, jet engines, amusement park rides, etc.
Practical implications
The outcome of this model can be utilized by asset and operations managers to make maintenance decisions based on prediction rather than more traditional time- or condition-based maintenance methodologies. This model is being developed for use as a module in a larger maintenance information system, specifically linking condition monitor data from the field to a predictive maintenance model. Similar methods are being applied to other applications outside the electrical equipment case detailed herein.
Originality/value
This model provides a structured approach for managers to decide how to best allocate their resources across a network of inter-connected equipment. Work in this area has not fully considered the importance of dependency on systems maintenance, particularly in applications with highly variable repair and replacement costs.

Abstract
Purpose
The purpose of this paper is to review cotemporary maintenance programs and analyze factory production data for an SF6 gas filled circuit breaker population. Various maintenance techniques and studies are reviewed to understand the reliability of circuit breaker models and the impact manufacturing can have on long term maintenance considerations.
Design/methodology/approach
Production and field event data were analyzed using statistical analysis tools. The population data were formatted so that a recurrent event analysis could be conducted to establish the mean cumulative function (MCF) by model and product family (class). Average Field Two‐year Recorded Event Rate (AFTRER) is introduced and compared to commonly used Field Incident Rate (FIR) and Mean‐Time between Failure (MTBF) measures.
Findings
Common managerial operating questions can be answered as exhibited for the provided circuit breaker population. This includes the longevity of field issues, the anticipated life cycle of a model or class, and AFTRER for models or classes of interest. These statistical analysis tools are used to make critical production quality and asset management observations and aid in decision‐making.
Research limitations/implications
Due to limitations in existing database systems, the cost of events and explanatory variables related to event rates were not included in the analyses. There remains much work to be done in terms of the installation and retro‐fitting of breakers with conditions monitors in the field.
Practical implications
A framework to analyze maintenance data from fleet of similar assets using recurrent event data analysis is provided. The methods illustrated here would be useful for quality and asset managers to make operating decisions. This includes resource allocation decisions across a network of equipment.
Social implications
Data analyzed are for power circuit breakers which are a critical element in the operation and reliability of the US power grid.
Originality/value
Using recurrent event data analysis to review and develop solutions to production quality and asset management problems including a comparison of AFTRER to FIR and MTBF measures.

The purpose of this paper is to provide insight into the relative importance of task, relations, and change capabilities of managers at low, middle, and top hierarchical levels.
Abstract
Purpose
The purpose of this paper is to provide insight into the relative importance of task, relations, and change capabilities of managers at low, middle, and top hierarchical levels.
Design/methodology/approach
Data were gathered from performance reviews and evaluations from human resources personnel for 2,307 managers in one large company in a high-tech industry. Separate regressions for each management level were performed with standardized regression coefficients allowing comparisons across the different regressions.
Findings
Significant differences were observed in the effectiveness of managers using task, relations, and change capabilities. At top management, change-oriented capabilities become 2 to 3 times more important than at the lowest level. Task-oriented capabilities become significantly less important at the top level. Relations-oriented capabilities are important at all levels.
Research limitations/implications
Studies with participants from multiple industries and longitudinal studies could benefit research by further validating the findings and offering new insights on other situational factors, which change over time.
Practical implications
Managers, who have been successful in lower and middle positions, may not necessarily be effective top managers.
Originality/value
Few studies have explored differences in managerial capabilities at different hierarchical levels in organizations. The study offers a clear rationale to consider when conducting any analysis of different levels of management by practitioners or researchers.

Abstract
Purpose
The purpose of this paper is to emphasize the need to engender a positive attitude toward business analytics in order for firms to more effectively transform into data-driven businesses, and for business schools to better prepare future managers.
Design/methodology/approach
This paper develops and validates a measurement instrument that captures the attitude toward business statistics, the foundation of business analytics. A multi-stage approach is implemented and the validation is conducted with a sample of 311 students from a business school.
Findings
The instrument has strong psychometric properties. It is designed so that it can be easily extrapolated to professional contexts and extended to the entire domain of business analytics.
Research limitations/implications
As the advent of a data-driven business world will impact the way organizations function and the way individuals think, work, communicate and interact, it is crucial to engage a transdisciplinary dialogue among domains that have the expertise to help train and transform current and future professionals.
Practical implications
The contribution provides educators and organizations with a means to measure and monitor attitudes toward statistics, the most anxiogenic component of business analytics. This is a first step in monitoring and developing an analytics mindset in both managers and students.
Originality/value
By demonstrating how the advent of the data-driven business era is transforming the DNA and functioning of organizations, this paper highlights the key importance of changing managers’ and all employees’ (to a lesser extent) mindset and way of thinking.
