Optimism bias tends to impact human decision making in various supply chain setting. We analyze how optimism bias would change the procurement strategy of the buyer. We demonstrate how behavioral bias of the buyer can impact the procurement strategy. Our main finding is that the optimism bias leads to booking larger capacity from a wider vendor base.

The automotive industry is facing intensified challenges due to shortened product life cycles, increasing individualization, an uncertain demand, and pressure to innovate caused by e-mobility. Currently, there is no suitable technology for the economic production of deep drawn parts in low quantities. Due to tooling lead time and costs, deep drawing is only economical in high quantities. To ensure profitability along common annual quantities, the literature shows various approaches, e.g. sheet metal forming by AM tools. Therefore, the aim of this paper is to summarize current approaches presented in the literature and evaluate those using criteria, e.g. tooling costs, sustainability, and product flexibility.

Modern constructions are typically monitored with geodesic monitoring systems. One the most important challenges for these systems is represented by the complexity of developing new instance from the ones already set up. The solution introduced herein is based on a service oriented architecture, which in turn relies on an enterprise service bus as its principal component. The monitoring system consists of three principal components: measurement system, data cleaning and integration, and the deformation analysis tool. By employing the herein proposed approach these three components become loosely coupled. Herein, the focus lies on the component performing data cleaning and integration, consisting of three principal chains of services linked either serially or sequentially. The first chain manages the files containing the observations recorded by the tachymeters which perform the object monitoring. The second chain manages the data sent by the humidity and temperature sensors. The third chain performs preliminary analysis functions, and also makes the results public on a website. Error management at bus level is performed by a fourth chain in the ESB: it manages the issues of language level error handling and improves the transparency. Due to the loose coupling characteristics of the system, the components can be developed in parallel. Together with the improved flexibility and the greater reusability, this is a key aspect of a service oriented architecture.

The paper takes the high school students as the research object, discusses the factors influencing the self-directed learning of such a special group, selects 306 high school students from Yunnan Province and Xiamen City, studies the relation between the students' parenting style, the teacher-student relationship and the students' self-directed learning by means of questionnaire survey, explores the mediating effect of the core self-evaluations therein, and conducts the data analysis with softwares SPSS22.0 and AMOS22.0.The results of the study confirm the psychological mechanism that the parenting style and the teacher-student relationship do have an influence on the self-directed learning of high school students and that the core self-evaluations plays a partial role in mediation of their relation, which have proposed some suggestions on the high school students' self-directed learning.

In sugar production, the vacuum pans used for crystallisation constitute one of most important systems and replacement costs are a significant capital expenditure. The maintenance strategy for pans is currently conducted on a time-based approach. This paper proposes a condition-based maintenance (CBM) model for pans, which is applied to a real multi-component pan operating in an Australian sugar mill. The maintenance policy is formulated as a Markov Decision Process (MDP) and solved via approximate dynamic programming. The results show a 10% saving on total maintenance costs compared to the time-based maintenance strategy.

In interbank networks, creditor banks tend to gain appreciation in asset value by borrowing liquid assets to debtor banks. Meanwhile, funds shortage leads debtor banks competing for the liquid asset, which forms a typical resource competing coupling relationship that affects the whole system. Existing research on interbank risk contagion mainly under the hypothesis that systemic risk in interbank network has accumulated to the threshold, so the behavior of banks in the accumulate process is regarded as static. it ignores the active behavior that derived from resource competing between banks. Therefore, this paper proposes a novel coupling relationship based on resource competing between banks, which takes the liquid assets as constraint, aimed to find proper ways to allocation liquid assets of creditor banks. We further study the influence of resource competing on the risk contagion of interbank network. Then, a network resource optimizing strategy is proposed to control the risk under different initial conditions.

A green mixed fleet vehicle routing with realistic energy consumption and partial recharges problem (GMFVRP-REC-PR) is addressed in this paper. This problem involves a fixed number of electric vehicles and internal combustion vehicles to serve a set of customers. The realistic energy consumption which depends on several variables is utilized to calculate the electricity consumption of an electric vehicle and fuel consumption of an internal combustion vehicle. Partial recharging policy is included into the problem to represent the real life scenario. The objective of this problem is to minimize the total travelled distance and the total emission produced by internal combustion vehicles. This is a new variant of problem which is developed from a mixed fleet of electric and internal combustion vehicles, full recharging policy, and operational cost minimization. A mixed integer programming model is then developed to address this problem and commercial software is utilized to solve the model.

This study proposes an ergonomics-based approach for those who are living in small housings (known as flats) in Indonesia. With regard to human capability and limitation, this research shows how the basic needs of human beings are captured and analyzed, followed by proposed designs of facilities and standard living in small housings. Ninety samples were involved during the study through in-depth interview and face-to-face questionnaire. The results show that there were some proposed of modification of critical facilities (such as multifunction ironing work station, bed furniture, and clothesline) and validated through usability testing. Overall, it is hoped that the proposed designs will support biopsychosocial needs and sustainability.

The degradation of mechanical systems is a typical phenomenon accompanying most systems. When considering dependability, safety and cost-effectiveness, the degradation may result in serious consequences. Direct advancing degradation in all technical systems is not easy to observe. In order to do so, related information is used, e.g. the study of diagnostic and operation measures-signals. This article presents a study of the deterioration of a mining head with multi-tool knives. There is a dataset containing the records of the drilling head behaviour in standard operation. The records contain typical operation characteristics such as moment and power for both sharp and blunt knives. Degradation modelling of the studied mining head knives is performed with stochastic continuous diffusion processes. They are Pearson type, Gauss-Markov type and Levy type processes. The achieved results are expected to be used for the observation of i) the first passage time of degradation critical value), ii) the prediction of residual useful life, and iii) the rationalization of in field operation and maintenance.
