Coupling system design and project planning: discussion on a bijective link between system and project structures

Abstract This article discusses the architecture of an integrated model able to support the coupling between a system design process and a project planning process. The project planning process is in charge of defining, planning and controlling the system design project. A benchmarking analysis carried out with fifteen companies belonging to the world competitiveness cluster, Aerospace Valley, has highlighted a lack of models, processes and tools for aiding the interactions between the two environments. We define the coupling as the establishment of links between entities of the two domains while preserving their original semantic, thus allowing information to be collected. The proposed coupling is recursive. It enables systems to be decomposed into subsystems when designers consider complexity to be too high, and can also decompose projects into sub-projects. The coupling enables systematically links to be drawn between project entities and system entities. In this paper, we discuss the different possibilities of linking system and project structures during the design and the planning processes. Firstly, after presenting the results of the industrial analysis, the different entities are defined and the various coupling modes are discussed.

Performance evaluation of disaster monitoring systems

Understanding the performance of disaster monitoring systems is a key to understanding their success; therefore, various qualitative and quantitative measures and metrics can be applied in the characterization and analysis of such systems. Through evaluation studies, problems that impede a disaster monitoring system performance can be identified. The results can be used for system design, control, and capacity planning. Previous studies address technical performance analysis metrics for analyzing monitoring systems leaving out human and organizational dimensions of such systems. Thus, the primary objective of this study is to identify and describe a set of metrics that may be employed to evaluate such systems. This study may be valuable to researchers and practitioners involved in disaster and emergency response studies in planning the transportation of vital first-aid supplies and emergency personnel to disaster-affected areas and in improving chances of survival after a disaster.

Study of operational parameters improvement of natural-gas cogeneration plant in public buildings in Thailand

This paper presents two case studies of performance improvement alternatives. The first one is the 52.5MWe cogeneration plant at the Suvarnabhumi Airport, and the second is the 9.9MWe cogeneration plant of the government office building complex. Both plants are located in Bangkok. Performance improvements assume changing system design and operational plans during on-peak and off-peak periods with applying chilled water storage for more flexible operation. Such analysis gives opportunity for improvement of plant efficiency, primary energy saving, emission reduction and economical benefits. In case study 1, the selection of new prime mover results in overall efficiency improvement from 48% to 61%, 24% increase of primary energy saving, and 27% improvement of CO2 emission reduction. Significant amount of primary energy is saved 1451TJ/a and CO2 emission reduction is 129,271tCO2/a. The profit is increased to 24.80 Million US$/a and the payback period is 4.77 years. In case study 2, the application of chilled water storage leads to maximum profit of 2.63 Million US$/a. The results show that the selection of plant components should be made very carefully in the design stage, as well as that permanent control and optimization of plant operation in the exploitation phase is essential. Economic aspects of cogeneration plants are more sensitive to changeable input parameters than classical separate heat and power generation since cogeneration plants are more complex in the aspects of process configuration and products costs/values (electricity, steam, hot water, and chilled water). Having in mind the future development of the natural gas distribution network in Thailand, it can be estimated that the potential of power generation in public buildings is around 1.3GWe. Comparing the Thailand total primary energy supply for commercial buildings, it means reduction of about 9.1%.

Modern Product Design Platform in Distributed Resource Environment

The resources that product design relies on are more distributed than ever along with the varying of the global design environment. More and more resources outside of enterprises are needed during the product design process. The Modern Product Design platform supporting the product design under the circumstance of distributed resources will meet the requirement of the enterprise's product design and development under such conditions, and will simplify the implementation of the IT support system for integration of design resources outside of enterprises. In this paper the characteristics and supporting technologies of product modern design platform, which supporting the distributed design resource circumstance and centering on the enterprise, are studied. The building method of the platform is presented and a prototype of the product design platform is developed. Three subsystems are included in the platform; they are product requirements analysis system, product design planning system and design knowledge management system. Many design tasks can be supported on the platform, such as product requirement analysis, concept design, detail design, and experiment. The distributing, implementing, tracking and managing of product design lifecycle tasks can also be supported on the platform. The distributed design resources could be sealed as application components to provide design services. Design work flow model and knowledge flow model are built and controlled on the design platform. The design knowledge is managed based on the Six-Dimension Knowledge Classification.

Sustainable energy planning based on a stand-alone hybrid renewableenergy/hydrogen power system: Application in Karpathos island, Greece

This study presents the sustainable planning of a renewables-based energy system, which aims to fulfil the electric needs of the island by replacing the existing diesel generators with new wind farms, photovoltaic installations and hydrogen production systems. Electric system design and least cost planning analysis were concluded using historic data from both demand and supply sides. An optimal “sustainable island” scheme should ensure 100% use of renewable energy resources for power generation, while hydrogen production is ideal for covering storage and transportation needs. Due to its morphology and scale, Karpathos applies perfectly for wind and solar energy systems, due to increased solar resource (about 1790 kWh/m 2.year of global irradiation) and high wind potential (average of 9 m/s in specific locations). Therefore, this case study examines an increase in RES penetration up to 20% in the electric energy mixture, a hydrogen production plan just for the needs of transport and a more aggressive, 100% renewables scheme that ensures a self-fulfilling energy system based on indigenous renewable resources.

An integrated information system for product design planning

In recent years, new product development (NPD) has become more and more competitive and globalized, and the planning phase is absolutely critical for the success of a NPD project. Quality function deployment (QFD) has been recognized as one of the most important approaches for NPD. Nevertheless, the issues of product design scheduling and costing have not been explicitly addressed in the deployment process. On the other hand, the design structure matrix (DSM), a popular representation and analysis technique, has led to its increasing use in a variety of contexts, including product development, project management and system engineering. In this paper, we develop a novel framework which integrates QFD and DSM to support product design planning, including product architecture/components deployment, design scheduling and costing. A knowledge-based database is developed to support the proposed framework. The details are presented and a prototype product design planning system is implemented with a practical application in the semiconductor industry, system-on-a-chip product design planning, to validate the completeness and benefits of the proposed approach.

Strategic Manufacturing Planning Systems and Their Linkage to Planning System Success

ABSTRACTAcademics and practitioners alike are focusing more attention on manufacturing strategy after having recognized the important role it plays in shaping the success of industrial firms. Even though research in this area has increased in the last decade, the focus of much of that work has been on the content rather than the process of the manufacturing strategy. Consequently, this study attempts to understand the important elements of the strategic manufacturing planning process and its effectiveness. Borrowing from the extant literature in the fields of strategic management and information systems, we propose a research model that relates strategic manufacturing planning system design to planning system success. Using structured questionnaires, empirical data is collected from over 200 manufacturing executives to test the model hypotheses. Planning process in manufacturing was found to be a bottom‐up approach from a corporate or business perspective, which differs from the top‐down planning process prevalent in strategic information systems planning process. Findings also indicate that greater planning system success in manufacturing is associated with a planning system that combines some “rational” elements (formality, comprehensiveness, control focus, longer horizon) with others that lend adaptability (wider participation and more intense interaction). But the strategic manufacturing planning system is more than just a collection of independent planning characteristics. Instead, it can be viewed as a gestalt planning system whereby planning characteristics move together in affecting overall planning system success.

The earliest Pleistocene(?) Orange River fan-delta: an example of successful exploration delivery aided by applied Quaternary research in diamond placer sedimentology and palaeontology

Understanding how complex, highly variable sedimentary systems interact in time and space to release, transport and concentrate diamonds is the basis for successful exploration strategies for placer diamond deposits. De Beers’ and Namdeb's West Coast operations are widely involved in a variety of applied scientific research to unravel the complex interactions of Cainozoic fluvial, marine and aeolian systems that have contributed to the formation of the most spectacular gem diamond placer in the world. Geological models produced not only provide the basis for exploration target selection but also high-resolution orebody characterisation, a prerequisite for high confidence geostatistical evaluation, mining system design and mine planning. This paper draws on some of the many applied research projects that have contributed to De Beers’ and Namdeb's placer exploration success that continues to deliver new mineral resources on the West Coast. The history of the Orange River has, and continues to be intensively studied both on- and offshore as the principal conduit for diamond introduction to the continental margin. Use of the “Jago” submersible has introduced a new dimension to offshore sedimentological studies on the continental shelf through direct seafloor observation, which helped us to identify the latest deep-water offshore development—the late Pliocene/early Pleistocene Orange River fan-delta.

Quality system design and information planning

The different steps in the development of a new quality management system resemble the phases known within information planning. However, there is one substantial difference: the methods of information planning are in an adult stage and have been supported by computerized aids for years because of their affinity with information technology. This article illustrates the way in which existing similarities between quality control and information control can lead to a model for mutual support. A general model has been designed from information planning, which can serve as an aid in developing quality management systems. Moreover, it goes into the application of the ideas described in an existing organization.

Design planning for high-performance ASICs

Design planning is emerging as a solution to some of the most difficult challenges of the deep-submicron VLSI design era. Reducing design turnaround time for extremely large designs with ever-increasing clock speeds, while ensuring first-pass implementation success, is exhausting the capabilities of traditional design tools. To solve this problem, we have designed and implemented a hierarchical design planning system that consists of a tightly integrated set of design and analysis tools. The integrated run-time environment, with its rich set of hierarchical, timing-driven design planning and implementation functions, provides an advanced platform for realizing a variety of ASIC and custom methodologies. One of the system's particular strengths is its tight integration with an incremental, static timing engine that assists in achieving timing closure in high-performance designs. The design planner is in production use at IBM internal and at external ASIC design centers.

Computer System Performance Evaluation Using Queueing Network Models

This paper reviews recent developments in the use of practical queueing­ based tools, particularly queueing network models, to study the performance of computer systems. We emphasize those research results that have been responsible for the successful transfer of this technology-the widespread use of these tools in computer system design, sizing, and capacity planning by people whose expertise lies in these application areas, rather than in modeling or mathematics. Queueing theory as a discipline dates from the 1920s. Almost without exception, the results of the early decades concern models of single conges­ tion points. These results encompass a wide variety of specific assumptions about the arrival process, the service process, the scheduling discipline, the queue size limitation, etc. Applications of these single resource models are found in many areas, particularly operations research, management science, and industrial engineering. In computer system engineering, these models have met with great success when used by skilled practitioners for the one-time analysis of subsystems, e.g. a specific communication network

Development of SUPKIT-II: Computer Aided Fault Tree Analysis System

A computer aided reliability analysis system, in which an interactive graphic terminal can be used, to construct, modify, analyze, and store fault trees is developed. The system, SUPKIT-n, a computer aided fault tree analysis system has functions for fault tree automated construction (PREP) and fault tree graphics (GRAPH). The former automatically generates a fault tree by a hierachical structure based on system configuration and specifications, and/or from failure information, while the latter indicates, modifies, and evaluates the fault tree through CAD/CAM terminals. Therefore, PREP decreases man-hours and mistake occurrences in constructing fault trees and GRAPH enables users to evaluate system reliability and to compare system design plans easily and quickly.

Strategic Planning Systems Design and Operation

In the design and operation of strategic planning systems, it is assumed that the people involved have a financial incentive to make good plans and then to see that those plans are well implemented. The traditional financial incentive used to motivate managers' behaviors in the desired direction is the so‐called incentive compensation or annual bonus. Thus, when strategic planning systems are broadened to explicitly take this factor into account, they become strategic management systems.
