To consider the problem of outsourcing warranty repairs to outside vendors when items have priorities in service.
Abstract
Purpose
To consider the problem of outsourcing warranty repairs to outside vendors when items have priorities in service.
Design/methodology/approach
The repair allocation problem is formulated as a convex minimum‐cost network flow problem and solve it by the successive shortest path algorithm. The computation issues involved with the problem are also discussed.
Findings
Examples are provided to illustrate the cost benefits achieved due to the priority structure.
Research limitations/implications
The research uses a closed static allocation model. Future research efforts can expand our model by considering a dynamic allocation method or an open population model.
Practical implications
The paper can be a valuable resource to warranty managers who make decisions regarding the negotiations of warranty contracts and the allocation of items to outside repair vendors.
Originality/value
A warranty manager can apply our results to receive insight on the value of giving priority in service to special customers. In addition, resource allocation problems with an objective structure similar to our application can be efficiently solved using our algorithm.

Abstract
Purpose
The purpose of this paper is to review the literature on maintenance management and suggest possible gaps from the point of view of researchers and practitioners.
Design/methodology/approach
The paper systematically categorizes the published literature and then analyzes and reviews it methodically.
Findings
The paper finds that important issues in maintenance management range from various optimization models, maintenance techniques, scheduling, and information systems etc. Within each category, gaps have been identified. A new shift in maintenance paradigm is also highlighted.
Practical implications
Literature on classification of maintenance management has so far been very limited. This paper reviews a large number of papers in this field and suggests a classification in to various areas and sub areas. Subsequently, various emerging trends in the field of maintenance management are identified to help researchers specifying gaps in the literature and direct research efforts suitably.
Originality/value
The paper contains a comprehensive listing of publications on the field in question and their classification according to various attributes. The paper will be useful to researchers, maintenance professionals and others concerned with maintenance to understand the importance of maintenance management

Abstract
Purpose
Cross operation is a common operation method in the building construction process nowadays. Due to the crossover, each other's operations are disturbed, and risks also interact. This superimposed relationship of risks is worthy of attention. The study aims to develop a model for analyzing cross-working risks. This model can quantify the correlation of various risk factors.
Design/methodology/approach
The concept of cross operation and the cross types involved are clarified. The risk factors were extracted from cross-operation accidents. The association rule mining (ARM) was used to analyze the results of various cross-types accidents. With the help of visualization tools, the intensity distribution and correlation path of the relationship between each factor were obtained. A complete cross-operation risk analysis model was established.
Findings
The application of ARM method proves that there are obvious risk correlation deviations in different types of cross operations. A high-frequency risk common to all cross operations is on-site safety inspection and process supervision, but the subsequent problems are different. Cutting off the high-lift risk chain timely according to the results obtained by ARM can reduce or eliminate the danger of high-frequency risk factors.
Originality/value
This is the first systematic analysis of cross-work risk in the construction. The study determined the priority of risk management. The results contribute to targeted cross-work control to reduce accidents caused by cross-work.

This study aims to focus on the possibility of promoting saving behaviors in children by activating a future time perspective (TP) in their thinking.
Abstract
Purpose
This study aims to focus on the possibility of promoting saving behaviors in children by activating a future time perspective (TP) in their thinking.
Design/methodology/approach
An experimental study of 8- to 11-year-old children (N = 212) was conducted in which future and present hedonistic TPs were induced.
Findings
The results suggest that inducing a future TP can modify children’s financial behavior, making them more inclined to save their money. However, the induction of a present hedonistic TP had no significant effect on children’s financial decisions.
Originality/value
This study improves current theoretical knowledge concerning the effectiveness of psychological interventions in fostering saving behaviors in children and answers the question posed of how the economically desirable behavior of saving may be enhanced in children. Thus, inducing a future TP in children by showing them the benefits of focusing on the future might constitute a useful means of strengthening children’s saving abilities.
