Power systems industry is faced with a new challenge that includes massive integration of electric vehicles in the power grid. Thus, it requires deep investigation of Electric vehicle's integration in the already developed grid control and operational structures, such as the microgrid concept. This paper is focused on the design and operation of a microgrid with the development of specific control functionalities to incorporate EV models for smart charging with vehicle-to-grid (V2G) implementation under normal and islanded modes. The modeling is done in Simulink to simulate the behavior of a MG for islanded modes under-voltage unbalanced conditions. It is found that EVs have different responses depending on the different droop parameters. It is seen that EVs have different responses depending on the droop parameters, where some EVs decrease the power being drawn from the grid.

An uncertain market demand for electrified vehicles leads to the establishment of scalable production systems. Their capacity can be extended step by step depending on the market development. A challenging aspect within this environment is the re-ramp-up of the production system after the implementation or adaption of production facilities. This paper demonstrates how virtual commissioning can be used to shorten and improve the commissioning phase of new production facilities and thereby ensure the re-ramp-up of production systems in time. Despite high cost and time saving potential, the development of a virtual model and the commissioning in the simulation environment causes a lot of effort. The paper identifies basic requirements as well as other factors of influence on virtual commissioning and provides an evaluation model which can be used by production engineers. The focus is to identify projects with a high potential and support the decision for or against using virtual commissioning within the expansion of a scalable production system.

This paper studies the production planning problem through the linear programming method. The study examines that it is an efficient method of operation research in the field of industrial engineering. Using the data of a Chinese company Z, which is a famous food company, the study analyzes the empirical results and obtains the following evidences. Firstly, the linear programming theory is very consistent with the actual production situation in China. Secondly, the real data of the company Z is used to derive the gross margin of one-unit product especially via the opportunity cost principle. Finally, one-period decision problem can be easily solved by the linear programming method and the results are reasonable and robust. In addition, the multi-period decision problem can be easily extended from one-period decision problem.

The turnover rate of courier employees remains high in China. The purpose of this study is to analyze the impact of personality traits, social support and group identification on courier turnover intention. Data were collected from 869 couriers, recruited from twelve representative express companies in China. SPSS 17.0 was used to explore the relationships among the proposed variables based on the hypothesized model. The results showed that personality traits are positively related to group identification while negatively related to turnover intention. Moreover, group identification is negatively related to couriers' turnover intention and plays a mediating role between personality traits and turnover intention. In addition, we found that social support moderate the relationship between personality traits and group identification. Personality traits of a person are difficult to change, but managers can reduce employees' turnover intention by providing social support.

The cellular manufacturing layout as the production management effects to increase the performance of the systems. The research area is to study the machines and parts clusters to allocate to layout locations under uncertainty. The layouts need to design to capture the realistic probability of demands. This paper, we addresses the discrete random probability of demands in cellular manufacturing system under multiple routes of parts. The objective is to minimize the expected total moving times of the material movement flow for the production lines. We formulate the dynamic programming model as a finite horizons. We investigate the model using the random data. Numerical examples are solved and presents the results of the sensitivity analysis. Finally, the model considers the demand fluctuation makes decision of the machine layout flexibility for high efficiency of the layout optimization problem.

Paper consumption in Peru has increased in recent years due to constant demand from companies. For example, approximately 90% of all the financial institutions still maintain a traditional paper-based work system, including the printing, storage, and inquiries of physical account opening documentation. Therefore, to reduce the number of physical documents handled, this study proposes a four-stage digitalization model. First, the necessary requirements are elicited. Then, the second stage identifies the main problem and defines improvement objectives. Next, the following tools are executed: change management, business and technology management, and a new digitalization process. Finally, the results obtained are verified against the expected results. The proposed model will be validated through a case study, wherein 35% reduction in unnecessary operating costs, 90% decrease in document inquiries, and 100% cut in documentation-related expenses were reported.

For the accuracy and timeliness of material distribution on the shop floor in uncertain environments, this paper constructs a dynamic material distribution method based on intelligent logistics technology under real-time monitoring of workshop. Based on the application of intelligent logistics technology, the real-time production progress monitored is taken as the basis to dynamically adjust the material delivery time window. A mathematical model is established to minimize the path cost, time window penalty cost and vehicle use cost, and a hybrid heuristic algorithm is designed to solve the problem. Finally, the effectiveness of the method is verified by an example of an automobile body production line. Compared with the traditional algorithm, the improved hybrid algorithm has more efficient optimization capability.

Focused on value-adding activities, Lean Manufacturing (LM) is already widely known and used in the productive environment. On the other hand, the new technologies from Forth Industrial Revolution are promising trends in industry. This work aimed to study the possibility of integration between the concepts of Industry 4.0 and Lean Manufacturing. After observing and categorizing the principles, attributes, technologies and guiding concepts of LM and Industry 4.0, a relationship matrix was developed by this study, associating each of the five LM principles with the attributes of Industry 4.0. It was identified 22 synergy points, which are also represented in the five proposed diagrams. These diagrams were developed to represent, in a visual way, the relationship of each LM principle and attributes 4.0, approaching organizational challenges, Lean tools, and technologies 4.0. As a result, it was proposed that LM and Industry 4.0 can work together and collaborate mutually from a holistic integration perspective.

Existing risk control systems seeking to evaluate and alleviate the negative outcomes of industrial production crises typically fail to consider the role of human factors, such as managers' interpersonal emotion management. Yet, literature in applied psychology shows that leaders elicit very different reactions from others as a function of leaders' abilities to regulate their emotions and those of people around them, particularly in times of crisis. Unfortunately, these two research communities tend to work in silos. Consequently, this research aims at developing a decision-making meta-model for addressing production crises that relies on both management science and applied psychology. A practical production crisis decision model is developed that couples the formalized decision making framework of a Markov Decision Process (MDP) with empirical data on interpersonal emotion management. This model is applied to cases of production crises or disruptions where managers use different levels of Interpersonal Emotion Management (IEM).
