CAD-MBSE Interoperability for the Checking of Design Requirements Based on Assemblability Indicators

A mechanical product is the result of collaboration between different domains. In this paper we focus on the collaborative work that brings together the system engineer and the designer in the realization process of a mechanical system. A design solution, conceived in the CAD environment, is considered valid if all the specification requirements, defined in the MBSE (Model Based System Engineering) domain, are met. Thus, the preliminary study of these requirements has a major influence on the choice and validation of the design solution. In this paper a methodology for handling the requirements has been detailed. These requirements are classified into two main categories. The first one deals with the product performance and the second addresses the process performance in order to generate the best assembly sequence. Depending on the response of the designed solution to these requirements, it becomes easy to decide not only whether the design solution can be validated or not but also to choose the most optimal assembly sequence that ensures the best operation quality. A validation example of a speed reducer is used to demonstrate the added value of the proposed approach.

DIGITAL FABRICATION AS A LEARNING MEDIA FOR LIGHTWEIGHT STRUCTURE WITH CASE STUDY OF SHELL STRUCTURE

The lightweight structure system is an effort to optimize the structure to distribute the load efficiently. Unfortunately, students often have difficulty imagining the learning outcomes application in the real world when studying light structural systems. However, the use of the scalar model can still explain several essential aspects of a lightweight structural system, one of which is the effect of connection and formation of material components on the structural capability. Therefore, this paper aims to bridge the learning process by utilizing digital devices from the concept stage of structural modeling with the help of software (Rhinoceros, Grasshopper, and Kangaroo) to the realization process using laser cutting. The method used is a semi-experimental method that applies Hooke's law principle, which produces a shell structure system with a digital fabrication approach that utilizes a lightweight material, namely, corrugated paper board, as the primary material. This paper concludes that digital technology and digital fabrication processes can help students understand the concept of lightweight structures because they can use computer simulations, cut them using laser cutting, and assemble them in the field in a series of simultaneous processes.

Recovery Factor Improvement; A Success Story of Improving 10% of RF in Greater Natih Reservoirs, North of Oman

Recovery Factor Improvement (RFI) is a process to check the hydrocarbon production efficiency by incorporating the actual static and dynamic field data, as well as the way how the field being operated. This has been a common process within Shell's portfolio since 2018 (Ref; Muggeridge et al., 2013 & Smalley et al., 2009). The approach has been developed to stimulate the identification of new opportunities to increase the recovery from the existing fields and to aid the maturation of these opportunities into the Opportunity Realization Process. There are four (4) factors that affected overall reservoir recovery factor, they are: Pressure efficiency; related to which pressure can be reduced in the reservoir as dictated by the relevant facilities and wells.Drainage Efficiency; the proportion of the in-place hydrocarbon that is pressure-connected directly to at least one producing well on a production timescale.The "secondary pay" efficiency; takes into account the volumes of poorer quality rock in which the gas remains at pressure above the lowest pressure just outside the wellbore (Pf) when the reservoir is abandoned.Cut-off Efficiency; the proportion of hydrocarbon that is lost due to non-production of the tail.This approach was applied in the dry gas Natih Reservoir fields in the PDO concession area. Before the implementation of RFI, the average recovery factor for Natih was around 70%. This was considered low for a homogenous-dry gas reservoir. The targeted Natih fields were benchmarked against each other with a total of 11 fields with similar reservoir properties. Post the benchmarking exercise, the expected field recovery factor is approximately ~90-93%. The team managed to map out the opportunities to achieve the targeted RF and identified the road map activities. The activities are mainly related to: production optimization: retubing, re-stimulation reduce drainage: infill drilling, horizontal well reduce the field intake through compression The outcome of the mapping was then further analyzed through integrated framework to be matured as a firm-project. The new proposed activities are expected to add around 9% additional recovery to the existing fields. There will be a remaining activities which will be studied in the future, example infill wells and intelligent completions. These will close the gap to TQ and add other addition RF of 11-13%. As conclusion, the RFI was seen as a structured approach to better understanding the field recovery factor based on the integrated surface and subsurface data with a robust analysis to trigger opportunity identification linked to RFI elements. It is similar concept as sweating the asset by generating limit diagram for each recovery mechanism & the road map to achieve the maximum limit. This paper will highlight the Natih Fields RFI analysis, highlighting the key learning and challenges.

Design Support Needs to Realize More Effective and Resource-Efficient Offerings: A Comparison Among Large Companies and Small and Medium Enterprises

In an economic paradigm where companies think that more is better and resources are considered infinite, waste, pollution, and environmental degradation are often the result. This can, in turn, be addressed by companies focusing on offerings that are both effective and resource efficient. However, this type of offerings can be more uncertain and complex due to multiple factors such as multiple actors and conflicting objectives taking place at once. Dedicated design support for the relatively new offerings will be helpful for designers in industry. Large and small companies could benefit from the dedicated design support to successfully realize these types of offerings. However, the type of support they might need is not clear. Differences and similarities among large and small companies could guide researchers in providing more reliable support. Therefore, the aim of this research is to present differences and similarities of design support needs among large companies and small and medium enterprises. This is carried out through semi-structured interviews and follow-up meetings. The results show that differences include a formal product realization process for large companies and an informal or no process for smaller ones. Similarities point at design support for better communication and management of their offerings with regard to lead time as well as lifecycle and strategic thinking for decision making. The conclusions highlight the importance for researchers to provide design support that purposefully addresses specific needs.

The Process of Designing the Post-Mining Land Reclamation Investment Using Process Maps. Case Study

In the present day, Europe is moving away from fossil fuels. This is due to the need to reduce CO2 emissions released to the atmosphere. As a result of this process, especially in Upper Silesia, Poland, there will be more areas requiring measures after the closing of mines. Reclamation of post-mining areas is a very difficult task, as there is no universal method of planning the recultivation. During mining operations, we observed many forms of environmental degradation. The article presents the use of one of the newer and increasingly used modeling methods in recultivation processes—the process map. Analysis of the investment is presented, based on the example of the recultivation of a pit after closing the hard coal mine. The main purpose of the analysis was to shorten the designing time of the construction and realization process. Two maps of processes were made, and a map of the existing and desired processes, as well as the benefits from this, are shown. This article presents only one of the stages of the recultivation process—the investment project process—, treating it as an example for optimizing the entire project related to recultivation.

Accountability of the 2020 Village Fund Allocation Management (Alokasi Dana Kampung) in Arul Pertik Village, Central Aceh Regency, Indonesia

In Indonesia, the central government provides Village Fund Allocation (VFA) to improve welfares in villages. This process, with its regulation, is known as alokasi dana kampung in Aceh province. However, irrespective of this implementation, the community's welfare is still not met, leading to the inability to meet management accountability. This study was carried out in Arul Pertik Village, using the qualitative method with a descriptive approach. The result showed that the VFA management team is open to accepting suggestions and advice during the planning and implementation process. VFA management in Arul Pertik tends to respect community participation, as seen from the number of participants in the development and implementation of the physical realization process. This is also in addition to the accountability report (LPJ), irrespective of the technical obstacles in the report. In conclusion, although the Management of Village Fund Allocation is quite good, it needs more extra guidance and supervision from the local government and the community. Keywords: Accountability; Village fund allocation; Village Fund Management, Arul Pertik Village.

Data Shepherding in Nanotechnology. The Exposure Field Campaign Template

In this paper, we demonstrate the realization process of a pragmatic approach on developing a template for capturing field monitoring data in nanomanufacturing processes. The template serves the fundamental principles which make data scientifically Findable, Accessible, Interoperable and Reusable (FAIR principles), as well as encouraging individuals to reuse it. In our case, the data shepherds’ (the guider of data) template creation workflow consists of the following steps: (1) Identify relevant stakeholders, (2) Distribute questionnaires to capture a general description of the data to be generated, (3) Understand the needs and requirements of each stakeholder, (4) Interactive simple communication with the stakeholders for variables/descriptors selection, and (5) Design of the template and annotation of descriptors. We provide an annotated template for capturing exposure field campaign monitoring data, and increase their interoperability, while comparing it with existing templates. This paper enables the data creators of exposure field campaign data to store data in a FAIR way and helps the scientific community, such as data shepherds, by avoiding extensive steps for template creation and by utilizing the pragmatic structure and/or the template proposed herein, in the case of a nanotechnology project (Anticipating Safety Issues at the Design of Nano Product Development, ASINA).
