Abstract. The designing and marketing models of general catering customer service APP are made from business owners needs or from commissioned design company's thoughts. The ZMET and MEC technique are used to understand the consumers more properly. Consumers usually will not purchase a product for just the physical content or functionality of the product but will do so because of other reasons, such as what the product presents socially, how it affects their emotions and more In this context, it is necessary to identify the meaning better. This research attempts to understand how customer satisfaction in the context of the catering industry could be understood better by identifying product and company attributes. The catering company can then develop a unique style of their own, so consumers can better understand the ethos of the company, their culture and style. According to consumers' experience, we conclude 5 user expectations of catering customer service APP, including Fans Evaluation, Online-to-Offline Consistency, Timeliness, Smart Order, and Customized Logistics. In this paper, the results of these information show that the user expectations of catering customer services APP will become the effective scientific reference and different patterns of cognitive communities.
The advantages of applying Internet in E-manufacturing are lower cost, enhancing distances in remote monitoring and control, but it may have time delay problem and it could decrease system performance and stability. In order to keep network control system more stable and effective, a human-centered automation approach was proposed in the network control system. Experiments were designed to identify significant factors of these network control systems, and the task was to command a mobile robot to complete the maze exploration with five kinds of human-centered network control systems. Total elapsed time and subjective evaluation are performance indexes and defined as dependent variables. Furthermore, personal hobby and level of automation for the network control system are independent variables. According to ANOVA results, level of automation indeed has a significant impact on the network control performance. The manual control obtained highest performance in total elapsed time of completing the task. It also showed that it is feasible to apply human centered automation in E-manufacturing.
The workflow management system should be flexible enough to manage workflow changes caused by new partnerships, new technologies, and new strategies in collaborative design. Therefore, this paper attempts to introduce the version concept of configuration management into the workflow management system to handle this problem. In this study, the baseline is applied to record the sequence of tasks in a workflow and the version number of the baseline is given whenever the workflow is created. Whenever any change happens, the version number of the task or baseline will be modified accordingly. Both version numbers of the baseline and the tasks are checked while the workflow is being processed, so that the user could notice any differences in the tasks or workflow and decides whether to use the newly changed workflow or to keep the old version. A JADE development platform was applied to develop a prototype system and the architecture was based on Workflow Management Coalition. A scenario was shown in this paper to verify the feasibility of this study, and the result showed that users can choose whether to use the modified workflow baseline or not, for any running processes. This approach increases the workflow flexibility for collaborative design projects.
Technology nowadays is always changing very fast. Automated tools are used to face the advanced technology in the warehouse industry, such as automated guided vehicles (AGV). It becomes a common daily vehicle when working in the warehouse, especially on the shop floor. It means collaboration between AGVs is needed and has become important. This paper suggests how to avoid collisions between AGVs and how to avoid obstacles is a practical problem if two or more AGVs interact with each other. This is a common need that should be addressed. As a result, a more effective system design should be created and implemented. This paper used a three-tier internet of things (IoT) structure to avoid collisions and reduce path deviation to design an AGV collaboration system. The IoT was used to authorize AGVs to communicate with each other by transmitting position messages. In this situation, AGV would be aware of other AGV positions and would decide what to do next. According to the findings, two AGVs can avoid colliding by knowing each other's positions in any path scenario by recognizing obstacles through Light Detection and Ranging (LIDAR) detection. This paper designed an AGV collaboration system using the Robot Operating System (ROS) and conducted an experiment to test its practicality. The experiment simulated a warehouse intersection in the real world. This study used the statistical ANOVA method to identify motion planning parameters concerning final AGV position error values.
The scheduling problem of LED chip sorting workstation is a multiprocessor open shop scheduling problem. In practice, this problem is usually solved with finding a dispatching rule to achieve certain performance indexes. Experimental design was applied to find a proper rule, and dispatching rule, wafer quantity, wafer mix type, and bottleneck location were chosen as independent variables. Maximum make-span and average queuing time were selected as dependent variables. Five dispatching rules were considered in the dispatching rule factor. Experimental results showed that all independent variables are significant on all dependent variables. While make-span as the performance index, three dispatching rules common in applying LPT in bottleneck machines obtained better results. A dispatching rule with applying SPT in non-bottleneck machines has least average queuing time among those three, and this rule is recommended for practical application.
