劉智明 Unknown Date (has links)
東柏林圍牆倒塌,金磚四國崛起,使得第三世界國家的經濟能力大幅提升,對能源及石化產品的需求也日益增加,促使全球對石化產業之投資大幅暴增且投資規模也較前期更大。為能加速獲利,業主經常要求統包工程公司能縮短1/3之工期。因此,統包工程公司需不斷研發及創新,並使用有別於傳統模式之作業方法,才可達成此縮短工期之目標。 近年由於電腦軟硬體進步神速及網際網路之普及化,提供了一個資訊交換的新環境。許多跨國作業、同步工程之應用系統紛紛被提出,但仍無法有效解決當前之問題,反而形成許多自動化孤島之資訊作業。 本研究主要目的在於探討如何利用先進資訊科技技術與國際共通的資訊標準規範,建立製程工廠統包工程所需之「建廠資訊生命週期管理」系統,將重要資訊予以電子化、結構化及標準化。透過電腦網路通訊及資料庫技術,使建廠過程能提供優良資訊品質,供參與建廠人員能透過此透明化之系統,使資訊得以整合與共享,確保資訊品質之完整、正確及一致性。 建廠工程之作業有許多不同的階段,本研究擬針對「建廠資訊生命週期管理」系統提出完整之規劃架構,但因本系統相當龐大,無法於短時間內完成全部之系統雛型,故,本著「Think Big, Start Small, Scale Fast」之理念,本研究將先對產製最多資訊之設計階段先行建立系統雛型,作為示範性之先導開發工作。本研究所獲得之主要結論如下: 一、 導入標準資訊規範是正確途徑 二、 為縮短建廠時間,需建立資訊整合與共享環境 三、 要提升統包工程公司之競爭力,需建立全球化作業平台 四、 要提升資訊品質需將文件中心轉變為資訊中心 關鍵字: 資訊生命週期管理、製程工廠、統包工程、圖形交換標準 建廠資訊交換標準、建廠工程活動、資訊品質、標準資訊規範 / The 3rd world economy has been largely improved resulting from the collapse of the Eastern Berlin wall and the rise of the Brics. Since then, the investment in the petroleum/chemical industries is increased triggered from a strong demand of the energy and petroleum/ chemical products. To expedite the profit return, the clients will usually request the turnkey project company to condense the plant’s engineering time to at least 1/3 of the original scheduled. Therefore, the turnkey project company needs to continuously engage in its R&D and create an innovation method different from the traditional one to fulfill with clients’ expectation. Owing to the rapid progress of the hardwares and softwares together with the popularity of the internet, it provids a new environment for the information exchange. Although numerous applications for global operation and concurrent had been announced, it still couldn’t resolve the existing problems, instead, it caused another problem and leads the information to the Islands of automation. The purpose of this study is to find out how to utilize the advanced information technology and worldwide standadized information specification to establish a 「Plant Information Lifecycle Management-PILM」system for the Process Plant. It is the hope that through the aforesaid system, user can transform their important information into a electronic、structured and standadized formular. In addition, by using the Internet communation and database technology, it can help the user to integrate and share information through this transparent system and ensure the completeness、correctness and consistency of the information quality. There are many phases in the plant engineering operation. Although this study is striving to provide a complete designing framework for the system of 「Plant Information Lifecycle Management」, however ,it is definitely impossible to complete the whole system prototype for this huge system during such a short period. Therefore, this study will focus only on the “Design Phase” based on the core principle “Think Big, Start Small and Scale Fast”. Most of the information will be emerged during the Design Phase, so that, a system prototype for this phase will be designed as an initiative development model. The major conclusions for this study are as follows: 1. The international standards should be adopted by the Turnkey project company. 2. To reduce the plant engineering time, an integral and share environment (the PILM system) should be built. 3. To enhance the competitiveness of the Turnkey project company, a global application platform (i.e. The PILM system) needs to be established. 4. To lift the information quality, the document centric needs to be transformed to data centric.

Walid, Abdelrahman January 2014 (has links)
Long Term Evolution (LTE) known in the market as 4G LTE, it is an evolution of the GSM/UMTS standard. The overall aim of LTE was to provide a new radio access technology focusing on packet-switched data only. LTE has provided a new peak download rates, low data transfer latencies, and improved the support for mobility. 3Th Generation Partnership Project (3GPP) specialized that LTE released 10 and beyond known as LTE-advanced it is the second evolution of LTE. It has some services such as Coordinated Multipoint Transmission and Reception (CoMP), evolved Multimedia Broadcast and Multicast Service (eMBMS) with Multicast-Broadcast Single-Frequency Network (MBSFN). The development still continuous on LTE-advanced, it is intended to meet the requirement of advanced application that will become common in the wireless marketplace in future. The goals of this project is to simulate one of LTE-A services on LTE standard such as CoMP or/and eMBMS with MBSFN using OPENT LTE, and measure some statistic such as spectral efficiency and also some other statistics, describe centralization vs. decentralization in LTE, and synchronization in the base station in LTE. OPNET LTE support eMBMS with MBSFN, and don’t support CoMP, the simulation has been done by using eMBMS with MBSFN. Finally the objectives of the project has achieved, the result show that when eMBMS with MBSFN is implemented the throughput increased in the downlink to about 5.52 Mbps and in the uplink to about 5.18 Mbps, and also the system spectral efficiency increased in eNB1 from about 10.25 (bits/s/Hz/cell) to about 13.75 (bits/s/Hz/cell) and in eNB2 from about 10.25 (bits/s/Hz/cell) to about 17.25 (bits/s/Hz/cell). The project also answers if it is possible to have centralization in LTE, describe synchronization in the base station in LTE, and if OPNET is useful for big research.

Energy Services in Shanghai

De Geer, André, Melander, Mathias January 2013 (has links)
The People’s Republic of China (PRC) is one of the fastest growing economies in the world. However, the economic expansion is not without complications. Improved standard of living and a growing industrial sector have led to an increased demand of energy, which in turn is contributing to air pollution and land contamination. The research problem of the study is what is keeping existing Energy Services (ES) in Shanghai from being used more frequently. To answer this, a sequential mixed method study is conducted, divided into a qualitative and quantitative part. The literature study indicates a great potential for ES in Shanghai. This is mainly due to great efforts taken in Energy Efficiency (EE), an attempt to face the rapidly increasing population by reducing the usage of energy. A number of barriers for ES are found throughout the existing literature, including market, financial, institutional as well as technological barriers. To further investigate barriers and opportunities on the ES market in Shanghai, 14 semi-structured interviews with relevant stakeholders and academics were conducted. Hypothesizes were formulated based on results from the interview and literature study as well as an expert panel. To test the hypotheses a questionnaire was sent out to real estate developers in Shanghai. This study discovers the need of bringing several in the literature identified barriers to ES in Shanghai up to date. Some barriers were found to be invalid while others were not identified at all. The newly found barriers include market barriers, such as ES having low priority, poor technological understanding among clients, and complications approaching and communicating with potential clients.  For institutional barriers, it was found that the prevalence of low margins in the Chinese industries is holding back stricter regulations. Furthermore, the Energy Service Companies’ (ESCO) lack of understanding of ES from a system perspective is considered a technology barrier. In addition to the barriers, a number of opportunities were found. Improved communication between real estate stakeholders and ESCOs contribute to greater awareness and knowledge, which in turn leads to a higher degree of investment in ES. Differentiation of the services offered by ESCOs may attract new customers who previously were not interested, e.g. companies with short investment horizon. In Shanghai, there are a significant number of subsidies, regulations and laws favoring ES. Moreover, the rapid growth of Shanghai is considered one of the greater opportunities. To conclude, it was found that the maturity level among ESCOs in Shanghai was having large impact on the overall usage of ES. Fixed barriers, i.e. barriers nearly impossible to overcome, together with the large amount of small and inexperienced ESCOs is found to be hindering ES in the Shanghai commercial real estate sector from being used more frequently. / Kina ett är en av de snabbast växande ekonomierna i världen. Den ekonomiska expansionen är emellertid inte helt utan problem. Med bättre levnadsstandard och en allt större industrisektor ökar behovet av energi explosionsartat med förorenad mark och luft som följd.  Studiens problemformulering är vad det är som hindrar befintliga energitjänster i Shanghais byggnadssektor från att användas oftare. För att svara på denna fråga användes en sekventiellt multidisciplinär metod uppdelad i en kvalitativ och- kvantitativ studie. Utifrån litteraturen är det uppenbart att det finns en stor potential för användning av energitjänster i Shanghai. Främst till följd av stora satsningar på energieffektivitet i ett försök att möta den snabbväxande befolkningen med högre krav på levnadsstandard genom att minska energianvändningen. Ett antal hinder existerar emellertid inom Shanghais energitjänstemarknad. Inom dessa inkluderas allt ifrån marknads- och finansiella problem till institutionella och teknologiska komplikationer. För att vidare undersöka vilka problem och möjligheter det finns för energitjänster i Shanghai genomfördes 14 semi-strukturerade intervjuer med involverade aktörer och akademiker i Shanghai. Baserat på resultatet från intervjuerna tillsammans med litteraturstudien och en expert panel formulerades hypoteser härrörande energitjänstesituationen. För att testa hypoteserna genomfördes en enkätundersökning riktad till fastighetsutvecklare i Shanghai. Studien visade att många av de tidigare utpekade hindren för energitjänster i Shanghai behövdes uppdateras, varav vissa visade sig vara obsoleta och några inte gick att verifiera. Bland de nyfunna barriärerna kan nämnas marknadsbarriärer som låg prioritering för energitjänster, låg teknisk kompetens bland fastighetsägare samt svårigheter för energitjänstebolag att närma och kommunicera med potentiella kunder. För de institutionella barriärerna framgick att låga marginaler inom den kinesiska industrin håller tillbaka hårdare regleringar. Inom de tekniska barriärerna framkom att energitjänstebolag generellt sett brister i deras kunskap om energitjänster som kan tillgodose hela byggnaders energisystem. Utöver problemen identifierades även betydande möjligheter. Ökad kommunikation mellan aktörerna bidrar till större kunskap vilket i sin tur leder till en högre grad av energitjänsteinvesteringar. Genom att differentiera de tjänster energitjänsteföretag erbjuder kan de hitta nya kunder som tidigare inte varit intresserade, framförallt sådana med kort investeringshorisont. I Shanghai finns det ett betydande antal subventioneringar, regler och lagar som gynnar energitjänster. Även Shanghais tillväxt ses som en av de stora möjligheterna. Studien kommer fram till att en låg mognadsgraden bland energitjänstebolag i Shanghai negativt påverkan användningen av energitjänster. Existensen av flera fasta barriärer, barriärer som är svåra att påverka, tillsammans med det faktum att majoriteten av energitjänstebolag är små och oerfarna ses som den främsta orsaken till att energitjänster inte används i större utsträckning i Shanghai.
