Due to the professionalism and particularity of the power equipment, a reasonable inventory equipment quota forecasting and purchasing plan can guarantee the electrical power construction and maintenance work smoothly. Furthermore, an accurate quota forecasting can also save a large volume of liquid funds for the power companies. This paper establishes a reasonable spare parts demand forecasting and...
At present, optimization modeling has become a powerful tool to tackle emergency logistics problems. A multi-objective material supply model in an emergent disaster is first constructed in the paper. The differential evolution (DE) algorithm with constraint handling methods, specialized for the material supply model, is then presented. Finally, a simulation experiment is performed and our results...
Students' goal orientations impact their self-regulation, engagement, and achievement in post-secondary STEM courses. But, how students' goal orientations change across a semester and the impacts of these changes have not been extensively studied. Study purposes were to investigate goal orientation change across the semester, associations of goal change with achievement and self-regulation, and associations...
The primary goal of this mini-workshop is to assist participants in creating Inquiry Based Learning Activities (IBLAs) that promote better conceptual understanding for their students. This is part of more general goal of transforming engineering classrooms into more interactive formats that promote student engagement and lead to improved student outcomes. Specifically the workshop will introduce participants...
Removing material by grinding in damage areas is one task manage for hydraulics equipment maintenance. These operations are currently carried out manually and are difficult in the long run. EDF R&D analyzes the need and demonstrates the feasibility of mechanizing the machining operations done in the workshops. EDF R&D experience of hard material high speed machining with a 6-axis anthropomorphic...
The Drum Tower, Office of the President and Zhan Yuan Garden were selected as examples to investigate the present existence status and corresponding effectiveness of protection measures (especially chemical aspects). A new strategy of using sol-gel technique hybrided with chitosan was pertinently brought forward. The application prospect is analyzed. Results show that most of the construction and...
The use of Electrical Hazardous Area Classification drawings as a basis for communicating the degree and extent of explosive hazards within industrial facilities is explored. Existing occupational health and safety regulations are referenced to determine a link between operational activities and the use of electrical hazardous area classification drawings as a tool for hazard assessment and management...
The new manufacturing technologies of the world are increasingly demanding the design and redesign of new alternative products and processes that can be useful and low cost term. The alternative solution and methodology to innovate in manufacturing processes of incremental sheet metal forming is shown in this paper. Through the methodology Product design specification (PDS) as a practical and effective...
Under the new technical condition, the promotion of equipment complexity and high-tech features makes a significant increase in the workload of equipment support. Commands of support organizations become more complex. In order to meet these demands, the equipment support system has gradually evolved to the network structure. Network-centric equipment support system will become the development trend...
Public lighting's primary purpose is nighttime visibility for security and safety. How to meet so many requirements of so many stakeholders? The key to developing a good plan is to relate lighting to functions of public spaces, because street lighting is more than a technical requirement, a security need, or a design element. It can be thought of and utilized in terms of how the type, placement, and...
Construction and maintenance of road infrastructure is a major source of emissions and energy usage. Procuring green roads, however, is neither commonplace nor trivial to implement. New ways to enhance the green procurement of roads are therefore needed, and can potentially involve life cycle assessment and green labelling methods. Considering the complexity of the pavement industry sector with its...
The overall purpose of this project is to test the impact and potential benefits of Virtual and Augmented Reality technologies (AR&VR) to improve maintenance operation in industrial equipment. The main function for a Flapper valve of a Fuller-Kinyon type M pump is to prevent that the air generated to convey the bulk material through a conveying pipe flows inside of the material chute through the...
Technological innovations has always played an important role in economic growth and industrial productivity, but they have also potential to influence service industry. In particular, they can offer support to the process of servitization in manufacturing companies. This article presents a study regarding the prospective value that different technological innovations can offer to maintenance service...
In this paper, a ODBOM structure for oil-well construction process is designed by analyzing model and features of the ODBOM, and combining multi-layered and level-sorted BOM structure. Such design enables the construction of ODBOM tree, moreover simplifies both basic data preparation and data maintenance algorithm. In application, according to ODBOM consistency requirement, a consistency maintenance...
The purchase and storage of a real inventory plays an important role in carrying out the main manufacturing processes in an industrial enterprise. To optimize its level, with adhering to the rules of reducing the maintenance costs and carrying out production in uninterrupted manner, is a major challenge for manufacturing entities. The volume of stored maintenance part inventories is largely due to...
With today's highly reliable components, we are often unable to obtain a reasonable amount of test data under normal use condition. For this reason, accelerated tests method is the reasonable procedure to be applied. It is used to determine the reliability of a product in a short period of time by accelerating the use environment. Application of the method of accelerated tests can save cost that we...
Increasingly biomaterials for the repair of abdominal wall defects are used. The aim of this study was to evaluate adhesion formation of prosthetic meshes after intraabdominal implantation to repair a surgical defect in the anterior abdominal wall. This anatomical defect was repaired by one of the three types of previously sterilized meshes: 1) fibroin 2) fibroin with polyethylene glycol and 3) commercial...
The aggressive demand that production equipment experiences when the production rates increases and less time is available for equipment maintenance activities, turns critical equipment maintenance into a challenge. It is then when improvements to existing processes, data collection (tools and techniques), and failure root cause analysis become critical for machinery support. This paper presents the...
EXPRESS is a database tool the Air Force (AF) uses to prioritize depot maintenance of reparable spare parts based on warfighter need. Many studies have examined individual portions of EXPRESS, though few examine it as an entire system. This effort proposes a modeling approach for examining overall system behavior of EXPRESS using discrete event simulation. The emphasis of the model is to be flexible...
The planning of mechanized tunneling projects requires the consideration of complex constraints and project objectives. Process simulation provides a tool to virtually evaluate different concepts in changing environmental conditions. The consideration of uncertain influences is an essential task within the development of a holistic simulation model. Some aspects (e.g. technical disturbances) can be...
