The Production Management Improvement Model of Small and Medium-sized Permanent Magnetic Materials Manufacturing Companies

An integrated production planning and control model based on MRPⅡand JIT is put forward through analyzing the characteristics of magnetic materials manufacturing companies. Master Production Schedule with limited capacity and operational plan in workshop level based on the basic data of flow chart are formulated by this model which applied JIT idea and based on customer order demand. Push production is adapted during execution phase combined with process flow cards. The model is helpful to reduce inventory,keep certain flexbility of production and improve continuity and equilibrium of manufacturing process.

Recent advances in wave-driven triboelectric nanogenerators:from manufacturing to applications

The ocean is the largest reservoir of renewable energy on earth,in which wave energy occupies an important position due to its high energy density and extensive distribution.As a cutting-edge technology,wave-driven triboelectric nanogenerators(W-TENGs)demonstrate substantial potential for ocean energy conversion and utilization.This paper provides a comprehensive review of W-TENGs,from materials manufacturing and structural fabrications to marine applications.It highlights the versatility in materials selection for W-TENGs and the potential for unique treatments to enhance output performance.With the development of materials science,researchers can manufacture materials with various properties as needed.The structural design and fabrication of W-TENGs is the pillar of converting wave energy to electrical energy.The flexible combination of TENG's multiple working modes and advanced manufacturing methods make W-TENGs'structures rich and diverse.Advanced technologies,such as three-dimensional printing,make manufacturing and upgrading W-TENGs more convenient and efficient.This paper summarizes their structures and elucidates their features and manufacturing processes.It should be noted that all efforts made in materials and structures are aimed at W-TENGs,having a bright application prospect.The latest studies on W-TENGs for effective application in the marine field are reviewed,and their feasibility and practical value are evaluated.Finally,based on a systematic review,the existing challenges at this stage are pointed out.More importantly,strategies to address these challenges and directions for future research efforts are also discussed.This review aims to clarify the recent advances in standardization and scale-up of W-TENGs to promote richer innovation and practice in the future.

The Values ＆ Benefits of Umicore＇s Process Excellence Model

We will highlight the values Umicore's unique Process Excellence Model is based upon and how these do correlate with the overall culture of Umicore. Besides, we are going to explain about the benefits for the target industries that come along with our approach. Here, we will not mainly focus on the usually mentioned cost saving potential, but how also other aspects do create substantial value for the industries.

Non-asbestos Friction Materials Manufacturing in China--Present Situation and Future Prosperity

In the "Industrial Policy of the Motor Industry" which was published on Feb. 19, 1994, the Chinese Government focuses more attention on the development of auto parts industry aiming to adjust the industrial set-ups of auto parts industry, and foster and develop a number of backbone enterprises and striving for a greater progress in production scale, product development and production engineering in the end of the 9th Five-Year-Plan.CATARC has been authorized by the MMI to compose the contemplation and framework of the development of some key auto parts for the 9th Five-Year-Plan. The key auto parts are classified into 25 categories which are listed below:EFI system, spark plug, valve, tappet, piston & piston ring, bearing bush, turbo charger, diesel engine high-pressure pump, aluminium radiator, filters, diaphragm spring clutch, constant velocity universal joint, vacuum servo booster & master cylinder, non-asbestos friction materials, brake tube, brake hose, steering gear, steering ball joint, shock

Managing obsolescence of embedded hardware and software in secure and trusted systems

Obsolescence of integrated systems which contain hardware and software is a problem that affects multiple industries and can occur for many reasons,including technological,economic,organizational,and social factors.It is especially acute in products and systems that have long life cycles,where a high rate of technological innovation of the subcomponents result in a mismatch in life cycles between the components and the systems.While several approaches for obsolescence forecasting exist,they often require data that may not be available.This paper describes an approach using non-probabilistic scenarios coupled with decision analysis to investigate how particular scenarios influence priority setting for products and systems.Scenarios are generated from a list of emergent and future conditions related to obsolescence.The key result is an identification of the most and least disruptive scenarios to the decision maker’s priorities.An example is presented related to the selection of technologies for energy islanding,which demonstrates the methodology using six obsolescence scenarios.The paper should be of broad interest to scholars and practitioners engaged with enterprise risk management and similar challenges of large-scale systems.
