PENGEMBANGAN SOP (STANDART OPERATING PROSEDURES) PELAPORAN GANGGUAN DENGAN METODE GAP ANALYSIS

PT.XYZ Pekanbaru sector was formed through the decision of the board of directors number 001.k/023/DIR/1996 dated February 7, 1996. It can be seen that one of PT.PLN's service activities is receiving reports of disturbances from service units. In reporting the disturbances received by the Operations and Maintenance Department (OPHAR), there were still several problems with disturbances from each service unit (UL), namely (ULPTG) Teluk Lembu, (PLTA) Koto Panjang, and (PLTG/MG) Duri, in reporting disturbance, the information provided is not detailed so that the information received is not in accordance with the needs of the operation and selection department, there is no schedule for sending disturbance reports, disturbance reports are past schedule when there is a disturbance and long delivery times, and there is no evaluation report and recommendation report from the unit. services as well as the absence of a chronology of disturbance validation reports. By conducting a gap analysis, we will compare the current conditions with the ideal conditions expected by the OPHAR department regarding the current SOP for reporting disturbances. From the results of the gap analysis, it can be concluded that there are 2 (two) SOP procedures that have gaps because they are not in accordance with the company's EAM standards.

Model-Centric Fulfillment Operations and Maintenance Automation

As networks have evolved, there has been an evolution in how they are managed as well. This evolution has seen a move from manual configuration via command line interface (CLI) to script-based automation and eventually to a template-based approach with workflow to coordinate multiple templates and scripts. The next step in this evolution is the introduction of models to provide a more dynamic capability than is in place today. This chapter will discuss three major layers of modelling that should be considered during implementation of this approach: device models focused on the configuration of the hardware itself; service models focused on the customer or network facing services that leverage the hardware level configuration; and operational models focused on people, processes, and tools involved in application of device and service models. This includes the orchestration of activities with other tools, such as operational support systems (OSS) and business support systems (BSS).

Managing Fast-Track Construction Project in Qatar: Challenges and Opportunities

Fast-track construction projects are becoming increasingly prevalent in the construction industry, particularly where completion time is essential. A high adoption rate in some of the United Arab Emirate countries and the lack of a conceptual understanding of the challenges inherent in such may jeopardize the future sustainability of the construction sector. To make an informed decision about adopting a fast-track construction method, it is necessary to first identify the opportunities and challenges associated with it. Therefore, this study examines the critical challenges impeding the performance of Qatar’s fast-track construction projects. The research findings were analysed and triangulated using a real-life project as a case study and several data sources. The results of the research identified four critical categories of barriers: design and coordination-related, scope or change orders-related, material and equipment-related, and contractual-related barriers. In addition, strategies such as accurate information, constructability assessment, early involvement of operations and maintenance personnel, and the use of an effective change control system were identified for addressing the identified challenges. The findings are beneficial to professionals who are currently operating or planning to undertake construction projects in Qatar or other United Arab Emirate countries. This study recommends that project managers be more attentive to key barriers in order to improve the performance of fast-track projects and to meet clients’ objectives.

Improving Building Energy Footprint and Asset Performance Using Digital Twin Technology

This article presents a novel architecture by integrating the existing asset management theory with building simulation technology for effective maintenance strategies and operational control schemes. Building performance, value and energy usage collectively define the criteria for optimization. Building assets are partially or fully connected with building Internet of Things (IoT) and their real time conditions are accessible at all times. An asset’s value is derived from the functional contributions of that asset to the overall business objective of the system that it is part of. The architecture consists of digital twin, analytics and Business Value Model (BVM) engines and in-between gateways for data exchange. The paper provides illustrative examples for how the platform can serve operations and maintenance (O&M) objectives of existing and new buildings.

Success Factors of an Enterprise-Wide Digital Twin Strategy

While many companies have embarked on their digital transformation journeys implementing different forms of "Digital Twins" to cover specific business processes and challenges, their main challenge has been integrating these disparate Digital Twin projects into one single combined view to create significant new value and competitive advantage for the business. To be effective, the Digital Twin needs to be capable of supporting the entire asset lifecycle from the early phases of a capital project to operations and maintenance up to asset retirement, leveraging the same data in a platform able to support the end-to-end process. This paper looks at several approaches, which large owner operators at different levels of organizational information management maturity have used to build their Enterprise Scale Digital Twin strategies. It uses the lessons learned to highlight the successes and failures of these strategies and recommended approaches going forward. The results observed, identify that whilst there is a reasonably standard roadmap for approaching the development of Digital Twins most customers begin at different points along that journey. It also highlights that the end goal may not be the same across an Enterprise and that by taking the development of a Digital Twin as a series of incremental steps, independent of the starting point, serves to accelerate the journey by driving an increase in the organizational maturity in terms of People, Process and Technology and an improvement in data quality. One of the key components in any strategy was the ability to manage the information standard for the Digital Twin at an Enterprise level, for both greenfield and brownfield organizations and assets. The paper concludes the benefits of technical and commercial scalability and the requirements to get a solid manageable and trustworthy core of information should be at the heart of any Enterprise-wide Digital Twin strategy. This is contrary to the common approach of building a single detailed Proof of Concept (PoC) addressing as many use cases as possible and then templatizing that as an approach to repeat around the Enterprise, which often leads to failure on additional deployments where the maturity and challenges are different.

Review on the Thermal Performance on the Basis of Different Types of Material used in Ball Bearings

Bearing is a movable object, so frictional forces must be overcome in terms of moving the Bearing. To decrease the friction force on the movable methodology, different kinds of bearings have been used. The bearing gets its characterized by the fact that it is used to support a rotating axle or shaft. Because rolling bearings utilize balls or rollers, they are referred to as "rolling components." one can measure bearing expected lifespan depending on the material exhaustion if one can understand the operations and maintenance of loads and speeds. These computations should be based on the assumption that now the bearing is appropriately installed, lubricated, and moreover treated. It is unable to account for the impact of detrimental operating environment. Damaged bearing has a significant economic and industrial implications. Numerous substance are used in the bearing sector to several bearing elements. To achieve maximum bearing performance and durability, the products are deposited to obtain intended characteristics.
