A research on the article entitled "Product Lifecycle Management in Aviation Maintenance, Repair and Overhaul". This paper analyses the journal predicated on inputs which is covered in the course "Product Design and Development. Further, it points out briefly about Product Lifecycle Management (PLM) and the several stages of PLM over new product development process as well as the benefits associated with PLM over Aviation Maintenance, Repair and Overhaul (MRO) industry. Product Data Management (PDM) software in PLM are also talked about in this paper.
Summary of the article
The journal has three phases of debate, first period is release, second period is the about the experience of PLM and the ultimate phase is approximately PLM benefits in aviation MRO industry.
Phase 1: Your competition among the world in new product development leads to data sharing among the enterprise and customers i. e. from ideas, design, making, customer/assembly, service etc. to get over this PLM is proposed to have proper integration of customer, process, management and data to own control throughout the life span cycle amount of the product. Nowadays most of the business have used PLM in their design process to the maximum extent when compared to the other process in their product life.
Similarly in Aviation MRO industry, PLM has not yet modified to the extreme end compare to the look process in the aviation industry. The PLM in aviation MRO industry can be more worthy as the full total life period for an airplane is approximately moreover than 30 years.
Phase 2: PLM has been divided in to two management phases as shown in body 1. One is related to enterprise and other relates to product data (virtual venture). This content focus on the second phase which integrates computer aided design and developing through PDM. Product Data Management (PDM) system is the division of PLM, which communicate and gather the data from the initial process of concept development to the end life of the merchandise. PDM system organizes the computer aided design tools. PDM archives the client feedback, anatomist data and management data to include the information between your enterprise, customer, service industry and other end user of the product throughout its life.
Second period of PLM is further divided into four stages. First stage is concept development where the ideas from customer are sorted out and designed. Second phase is design. This specializes in describing, defining, producing the product design predicated on first phase and finally studying and simulation is carried out in design phase. The third stage is manufacturing and marketing where in fact the creation, sales and installation process are carried on to produce a new product. The ultimate period is servicing where maintain and support, removal or disposal i. e. customer support through MRO.
Figure 1: Different Stages of PLM
In basic PLM reduce marketing time, enhance the product quality in new product as well as in service, centralized product record, cost and misuse reduction. Many establishments have applied PLM as an effort and are typically found in design process. Relating to a review detailed in this article, it demonstrates the consumption of PLM and PDM in MRO are very inadequate when compared with design.
Phase 3: The adoption of PLM is in very high ratio in automotive and aeroplanes industry scheduled do life period and the impossibility in prototype; but in aviation service industry the percentage of PLM request implemented is deficient. PLM decrease the normal design and assemble period of aeroplanes in many plane industry. This lead to higher ratio of reduction in manufacturing process, however the percentage of decrease in life routine period is very less.
In aviation industry the income amount of the airplane is determined only based on the full total life period. It could be obtained only by proper maintenance and repair. From the article it pronounces that over 17000 commercial aircrafts are lively at present. The examination of budget in aviation MRO industry from the entire year 2005 to 2010 shows a massive increase. This upsurge in expense is due to inventories in the aviation MRO industry. The success of the aviation industry is determined by the life span of the aeroplanes. To have maximum income in airplane industry, they want safe operation, satisfactory maintenance for the parts. PLM in MRO will reduce enough time of maintenance, cost and also improve the total life amount of the airplane.
Maintenance is the procedure to achieve trustworthiness, safety and overall performance of the product. A couple of two types: one planned maintenance where the repair process is scheduled according to the time intervals and second some may be unscheduled maintenance and it suggests when there exists sudden breakdown. Previously the scheduled and unscheduled maintenance are known as precautionary maintenance. In addition to this, maintenance is further grouped into "On or OFF" aeroplanes maintenance. On maintenance signifies mended within the art without cancelling the transit. Off maintenance signifies the change of parts i. e. overhaul of parts. Here, the short-term part is changed till the repair process is carried out in the part.
The goal of PLM in aviation MRO industry is to acquire adequate reliability, security, proper data from OEM for overhaul and this will bring about cost reduction. To obtain product trustworthiness and safety in aircraft, both maintenance processes should be carried. For proper maintenance the major part of consideration is product and part manual from Original Equipment Manufacturer (OEM). To be able to minimize the issue of MRO the OEM has to provide the sufficient data's like ways of in depth data of the part, maintenance process, problem recognition method, tools required to overhaul and also 3D modeling drawing view of the part. These are accomplished by the PDM which will make use computer for safe data transfer from OEM to MRO and also by reviews from customer to OEM and MRO industry.
Case studies on different ways of how maintenance, repair and overhaul are carried out in different aviation MRO industry located in Singapore. They referred to the percentage of inaccuracy in their method of repair. They point out the repair work move procedure and the various ways of process they carried on for the repair of aviation part. The reason behind this inadequate quality of repair is examined below in this newspaper.
Journal relationship with "Product Design and Development"
The journal related to one of the primary area "Product Lifecycle Management (PLM)" which was covered under the lecture "PLM and Product Planning".
In addition to PLM "Product Data Management (PDM)" are also discussed in this specific article which is a part of PLM.
The information from the lecture about the tools PLM and PDM, offered the suggestions how to develop a fresh product with a competent lifecycle time i. e. from the procedure of idea creation to end life of the product or till recycling of the product and also effective data management system. These ideas are related to the service industry which is at the end period of lifecycle of something. This helps to identify the huge benefits and characteristic of PLM in aviation MRO industry.
Journal Analysis
The impact of Product Lifecycle Management (PLM) in aviation maintenance repair and overhaul (MRO) industry is examined in this specific article. They addresses the PLM benefits and requirement in MRO industry for effective and accurate quality in repair process. In addition they analyze the different maintenance process carried on in the aviation industry.
Figure 2: Current Situation Of Data Flow Without Adoption PLM in aviaton MRO industry.
In this informative article they analyzed that they repaired the high pressure blade and exterior cover panel. And yes it describes the demerits in their method without PLM. It shows the info flow from the OEM to MRO industry is inadequate as shown in the figure 2. Thus it leads to improper Maintenance, repair and overhaul of the part in aircraft. Product Data Management (PDM) system should be applied with PLM for proper flow of information between the OEM to customer, customer to MRO and also MRO to OEM and vice versa. Such opinions from customer end will improve the process in MRO in addition to design of aircraft. Thus the number 3 signifies the stream of data between various techniques in aviation industry. It shows the quality and benefits on adoption of PLM operating industry. Furthermore to service process PLM needs to be implemented in general management activities like Business Resource Planning (ERP) and supply chain management (SCM) in aviation industry to raise the total lifecycle time of the new product.
Figure 3: Implementaion of PLM with Product Data Management (PDM) in aviaton Industry.
The research study done on the aviation MRO industry in Singapore presents the work flow of the repair process carried out on various areas of aircraft. In such a, the original part classification data was assessed and computed by coordinate measurement system with the help of a reverse engineer. The measured data had not been too accurate in comparison with OEM data. This incorrect method is principally because of insufficient product data information. This method will lead to poor reliability and safety, life amount of the product is thus reduced and also overall life span of the airplane deteriorates. Further, it contributes to poor client satisfaction and very less profitability to the aviation industry.
The influencing factors that affect the MRO industry are inadequate data sharing between your OEM and MRO. To rectify the condition in aviation MRO industry, it must adopt PLM system offered with PDM. The writer suggests adopting the PLM process in MRO industry as the procedure implemented in design process shows impressive lead to that sector. Furthermore to design and service, PLM can be applied on various processes in the aviation industry that will clearly show a very important increase in the stability and protection of the aeroplanes. It also escalates the overall profitability of the merchandise. Furthermore, PLM provides regular and precise feedback between your OEM, MRO and customers and also between your companions in the business resulting in search engine optimization of the inventory and additional enhances the efficiency of maintenance by minimizing the non-value added responsibilities.
Conclusion
PLM activities in the aviation industry need to be analyzed more exactly and research must be transported in various procedure for plane and MRO industry to boost the industries' revenue and service. Furthermore to PDM, Collaborative Product Development (CFD), Concurrent Executive (CE) tools may also be used in future to boost the total life span of the aeroplanes and MRO industry.
