This thesis details the ongoing development of a new Offshore Floating Nuclear Plant (OFNP) concept that exhibits a promising potential for economic and rapid deployment on a global scale. The OFNP creatively combines state-of-the-art Light Water Reactors (LWRs) and floating platforms similar to those used in offshore oil and gas operations. A reliable and cost-effective global supply chain exists for both technologies, which enables a robust expansion in the use of nuclear energy on a time scale consistent with combating climate change in the near future. The OFNP is a plant that can be entirely built within a floating platform in a shipyard, transferred to the site, where it is anchored within 12 nautical miles (22 km) off the coast in relatively deep water (=/> 100 m), and connected to the grid via submarine AC transmission cables. Shipyard construction ensures a supply of qualified workers and facilities, and it brings mass-production-like construction efficiency to existing reactor designs. Eventual shipyard decommissioning allows sites to immediately return to a "green field" condition when the plant's life is spent. The crews would operate in monthly or semi-monthly shifts with onboard living quarters, similar to oil and gas platforms. The OFNP is a nuclear plant specifically designed for the global market: it can be constructed in one country or multiple countries and exported internationally. It lends itself to a flexible and mobile electricity generation strategy, which minimizes the need for indigenous nuclear infrastructure in the host country and does not commit the customer to a 40 to 60 years-long project.

In historical and current experience, the economics of nuclear power have proven to be problematic for utility companies. Construction costs and schedules have proven to be highly unpredictable, with the average reactor construction project costing two to three times more than its initial budget and taking almost twice as long to complete as expected. The causes of this phenomenon have not been well-characterized, even two decades after the last new reactor was brought online in 1996. Scenario generation can provide useful information about the economic viability of nuclear construction projects over a variety of parameter spaces without having to make prescriptive assertions about likely single values for delay and other difficult-to-predict parameters. The MEERKAT model creates scenarios over two different reactor types (Westinghouse AP1000 and NuScale SMR plant); three delay cases (optimistic, median, and pessimistic based on historical data); and six different utility company credit ratings (which translate into varying costs of capital). MEERKAT outputs the levelized cost of electricity (LCOE) for each scenario and compares them to average electricity prices for a number of regions in the United States. These scenarios produce levelized costs of electricity (LCOEs) that are not competitive in a deregulated market in any case, and which may be competitive in regulated markets under certain optimistic conditions. If the AP1000 is considered as more credit-stressful than the SMR project, the SMR becomes more competitive with the AP1000, but the projects' viability in the wider market remains unchanged. However, in general terms the smaller up-front cost of the SMR makes it a more feasible endeavor for a wider variety of utility companies, increasing the potential customer base for nuclear power generation units.

The recent serious reconsideration of nuclear power as a means for U.S. electric utilities to increase their generation capacity provokes many questions regarding the achievable success of future nuclear power plant construction projects. The troublesome nature characterizing much of the history of U.S. nuclear power plant commercialization provides impetus for an examination of the reasons behind the unanticipated outcomes of many nuclear power plant construction projects. An examination of the history of U.S. nuclear power provides for both an understanding of the historical context of the technology, in addition to an acknowledgement of the difficulties that have surrounded its commercialization. This thesis work identifies the factors that have contributed most significantly to the inability of U.S. electric utilities to successfully manage nuclear power plant construction projects. The historical record of these endeavors was used to create a causal-loop diagram. This diagram reflects a generalized decision-making process used by electric utilities when considering the pursuit of nuclear power plant construction. From the results of the diagram, policy changes are proposed that could reduce the susceptibility of the decision-making process to environmental instabilities and increase the overall attractiveness of the technology.

Повний текст джерелаENGLISH ABSTRACT: Grapevine leafroll is one of the most damaging viral diseases that affect many viticultural regions of the world. Numerous reports over the last few years have associated closterovirus-like particles with leafroll disease. To date, eight serologically distinct closteroviruses have been isolated from leafroll infected vines, of which grapevine leafroll associated closterovirus-3 (GLRaV-3) is the best characterized. Virus resistance in transgenic plants based on the expression of a virusderived gene is known as pathogen-derived resistance. The viral coat protein (CP) gene, which expresses a structural protein responsible for coating the virus particles, was used in the first demonstration of virus-derived resistance. Coat protein-mediated resistance is currently the most feasible and most widely used method to obtain virus resistance in crop plants. The CP gene of a South African isolate of GLRaV-3 infected grapevine was isolated, cloned and sequenced. Double stranded RNA (dsRNA) was extracted from GLRaV-3 infected material and a high molecular weight band, of -18 kb was identified from infected vines. The dsRNA was used as a template in a reverse transcription PCR together with GLRaV-3 CP gene specific primers for the amplification of the GLRaV-3 CP gene (975 bp). The GLRaV-3 CP gene was cloned into the pGem®-T Easy vector. Clones hosting the CP gene in the sense (pLR3CP+) and antisense (pLR3CP-) orientations respectively were obtained. The sequence obtained from these two clones showed 99.26 % similarity to the only other GLRaV-3 CP nucleotide sequence available. The GLRaV-3 CP gene was excised from pLR3CP+ and pLR3CP- and subcloned into a plant expression vector, pCAMBIA 3301 in the sense (pCamBLR3CP+) and antisense (pCamBLR3CP-) orientations respectively, therefore enabling sense and antisense gene expression in transgenic plants. The GLRaV-3 CP gene was also subcloned from pCamBLR3CP+ into another plant expression vector, pCAMBIA 2301 in the sense orientation and designated as pCVSLR3CP+. These three constructs were given to Dr. M. Vivier (Institute for Wine Biotechnology, Stellenbosch) for grapevine transformation experiments. Two of these constructs, pCamBLR3CP+ and pCamBLR3CP- as well as pCAMBIA 3301 were used to transform Nicotiana tabacum by Agrobacterium tumefaciens-mediated transformation. Plants were selected for their ability to withstand the herbicide, Basta. This resistance is due to the presence of a plant selectable marker gene on each of these constructs, known as the bar gene. PCR with GLRaV-3 CP gene specific primers showed no amplification of the GLRaV-3 CP gene in the plants transformed with pCamBLR3CP+ and pCamBLR3CP-. Southern blot analysis with the GLRaV-3 CP gene as hybridization probe showed no signal for these plants, thus confirming the PCR results. PCR with bar gene specific primers showed no amplification of the bar gene in the plants infected with pCAMBIA 3301. The plants transformed with pCamBLR3CP+ and pCamBLR3CP- were also screened for the presence of the bar gene. Three of the eight plants tested showed amplification of the -560 bp bar gene. This result suggests that these plants were transformed with pCAMBIA 3301 (vector without the ligated GLRaV-3 CP gene) and not pCamBLR3CP+ or pCamBLR3CP- as had been expected. This project provides preliminary work for the subsequent transformation of grapevine with the GLRaV-3 CP gene, in an attempt to impart virus resistance.
AFRIKAANSE OPSOMMING: Wingerd rolblaar is een van die mees beskadigende virale siektes wat baie wingerd areas in die wêreld aantas. In Aantal verslae oor die afgelope jare het closterovirus partikels met wingerd rolblaar geassosieer. Tot hede, is agt serologiese onderskeibare closterovirusse geïsoleer vanuit geaffekteerde wingerde, waarvan wingerd rolblaar geassosieerde closterovirus-3 (GLRaV-3) die beste gekarakteriseerd is. Virus bestandheid in transgeniese plante gebaseer op die uitdrukking van gene afkomstig vanaf virusse, staan bekend as patogeen-afgeleide weerstand. Die virale kapsule protein (CP) geen vervaardig In strukturele protein wat verantwoordelik is vir die bedekking van die virus partikel. Dié geen was gebruik in die eerste demonstrasie van patogeen-afgeleide weerstand. Kapsuul protein-bemiddelde weerstand is tans die mees praktiese en algemene gebruikte metode om virus weerstand in plant gewasse te verkry. Die CP geen van In Suid Afrikaanse isolaat van GLRaV-3 geïnfekteerde wingerde is geïsoleer, gekloneer en die volgorde is bepaal. Dubbelstring RNA (dsRNA) was uit GLRaV-3 geïnfekteerde materiaal geëkstraheer en In hoë molekulêre gewig band van -18 kb is geïdentifiseer. Die dsRNA is gebruik as In templaat vir In omgekeerde transkripsie PKR saam met GLRaV-3 CP geen spesifieke inleiers vir die amplifikasie van die GLRaV-3 CP geen (975 bp). Die GLRaV-3 CP geen is gekloneer in die pGem®-T Easy vektor. Klone met die CP geen in die sin (pLR3CP+) en teensin (pLR3CP-) oriëntasies respektiewelik is verkry. Die volgorde wat verkry is vanuit hierdie twee klone dui op In 99.26 % ooreenstemming met die enigste ander GLRaV-3 CP geen volgorde wat beskikbaar is. Die GLRaV-3 CP geen is uit pLR3CP+ en pLR3CP- gesny en is gesubkloneer in In plant ekspressie vektor, pCAMBIA 3301 in die sin (pCamBLR3CP+) en teensin (pCamBLR3CP-) oriëntasies respektiewelik, wat die sin en teensin geen ekspressie in transgeniese plante in staat stel. Die GLRaV-3 CP geen was ook gesubkloneer vanaf pCamBLR3CP+ in In ander plant ekspressie vektor, pCAMBIA 2301 in die sin orientasie en is as pCVSLR3CP+ benoem. Hierdie drie konstruksies is aan Dr. M. Vivier (Instituut vir Wyn Biotegnologie, Stellenbosch) gegee vir wingerd transformasie eksperimente. Twee van hierdie konstruksies, pCamBLR3CP+ en pCamBLR3CP- asook pCAMBIA 3301 is gebruik om Nicotiana tabacum deur middel van Agrobacterium tumefaciens-bemiddelde transformasie te transformeer. Plante is geselekteer vir hul vermoë om die onkruiddoder, Basta, te weerstaan. Die teenwoordigheid van die plant selekteerbare merker geen, bar, op elke konstruksie lui tot dié weerstand. Die plante wat getransformeer is met pCamBLR3CP+ en pCamBLR3CP- is deur PKR saam met die GLRaV-3 CP geen spesifieke inleiers getoets, en geen amplifikasie van die GLRaV-3 CP geen is getoon nie. Southern blot analise met die GLRaV-3 CP geen as hibridisasie peiler het geen sein gewys vir hierdie plante nie, wat die PKR resultate bevestig. Die plante wat getransformeer is met pCAMBIA 3301 is deur PKR saam met die bar geen spesifieke inleiers getoets, en geen amplifikasie van die bar geen is getoon nie. Die plante wat getransformeer is met pCamBLR3CP+ en pCamBLR3CP- is ook getoets vir die teenwoordigheid vir die bar geen. Drie van die agt plante wat getoets is, het amplifikasie van die -560 bp bar geen getoon. Hierdie onverwagte resultate stel voor dat dié plante met pCAMBIA 3301 (vektor sonder die geligeerde GLRaV-3 CP geen) en nie met pCamBLR3CP+ en pCamBLR3CPgetransformeer is nie. Hierdie projek verskaf voorlopige werk vir die daaropvolgende transformasie van wingerd met die GLRaV-3 CP geen in 'n poging om virus bestandheid te verskaf.

Повний текст джерелаThe present work investigates the hygro-mechanical performance of compacted earth as an alternative to conventional energy-intensive building materials. Earth bricks were manufactured by applying high compaction pressures up to 100 MPa (hyper-compaction) to increase the density of the earth and hence to obtain mechanical properties that are similar to those of traditional construction materials such as fired bricks, concrete blocks and stabilised earth. A wide campaign of laboratory tests was performed on samples made of different earth mixes that were hyper-compacted at their respective optimum water contents. Stiffness and strength were measured by unconfined and triaxial compression tests while vapour adsorption/desorption was assessed by measuring moisture buffering value (MBV). Durability to water erosion was also evaluated by performing suction, immersion and drip tests according to the norms DIN 18945 (2013) and NZS 4298 (1998), respectively. Results showed that hyper-compaction largely improved the mechanical performance of compacted earth but that a marked increase in ambient humidity could produce a considerable reduction of strength. Durability tests highlighted that the unstabilised compacted earth could not be employed for the construction of structures exposed to natural weathering. The experiments also demonstrated the dependency of strength, stiffness, moisture buffering capacity and water durability on particle grading. In particular, it was shown that a fine and well-graded earth mix exhibited higher levels of strength, stiffness, moisture buffering capacity and durability than a coarse and poorly-graded one. One important challenge lied in the improvement of the earth durability against water erosion by adopting novel stabilisation techniques, which led to the development of an original stabilisation method based on the utilisation of plant extracts. The method was consistent with the principles of Enzymatic Induced Calcite Precipitation (EICP), which utilises the action of the urease enzyme to catalyse the hydrolysis of urea. This reaction produces carbonate ions, which then react with the calcium ions dissolved in the pore water to produce the precipitation of calcium carbonate (i.e. calcite), thus binding the soil together. The novelty of the present work resides in the utilisation of crude plant-derived urease enzyme instead of pure reagent-grade products available from chemical suppliers, which reduces environmental and financial costs. In particular, the urease enzyme was obtained from a liquid soybeans extract, inside which the urea and calcium chloride were subsequently dissolved to induce the precipitation of calcite. Measurements of pH, electrical conductivity and precipitation ratio indicated that the optimum equimolar concentration of urea and calcium chloride (leading to the largest precipitation of calcite) was 2.5 mol/L. An experimental campaign was finally undertaken to implement the proposed bio-stabilisation method into the manufacture of compressed earth bricks. The most promising versions of the proposed bio-stabilisation method were also the object of further investigation to assess the hygro-mechanical behaviour of the stabilised earth by means of unconfined compression and moisture buffering value tests. The findings, although preliminary, suggested that a noticeable improvement of strength and water durability could be achieved by the proposed stabilisation protocol, in spite of the difficulty in replicating exactly quantitative results

Повний текст джерелаENGLISH ABSTRACT: The genetic information of plants is found in the nucleus, the mitochondria, and the plastids. The DNA of plastids is comprised of multiple copies of a double-stranded, circular, prokaryoticallyderived genome of -150 kb. The genome equivalents of plastid organelles in higher plant cells are an attractive target for genetic engineering as high protein expression levels are readily obtained due to the high genome copy number per organelle. The resultant proteins are contained within the plastid organelle and the corresponding transgenes are inherited, in most crop plants, uniparentally, preventing pollen transmission of DNA. Plastid transformation involves the uniform modification of all the plastid genome copies, a process facilitated by homologous recombination and the non-Mendelian segregation of plastids upon cell division. The plastid genomes are in a continuous state of inter- and intra-molecular exchange due to their common genetic complement. This enables the site-specific integration of any piece of DNA flanked by plastid targeting sequences, via homologous recombination. The attainment of homoplasmy, where all genomes are transformed, requires the inclusion of a plastid-specific selectable marker. Selective pressure favouring the propagation of the transformed genome copies, as well as the random segregation of plastids upon cell division, make it feasible to acquire uniformity and hence genetic stability. From this, a complete transplastomie line is obtained where all plastid genome copies present are transgenic, having eliminated all wild-type genome copies. The prokaryotic nature of the chloroplast genetic system enables expression of multiple proteins from polycistronic mRNAs, allowing the introduction of entire operons in a single transformation. Expression cassettes in vectors thus include single regulatory elements of plastid origin, and harbour genes encoding selectable and screenable markers, as well as one or more genes of interest. Each coding region is preceded by an appropriate translation control region to ensure efficient translation from the polycistronic mRNA. The function of a plastid transformation vector is to enable transfer and stable integration of foreign genes into the chloroplast genomes of higher plants. The expression vector constructed in this research is specific for the transformation of the grape chloroplast genome. Vitis vinifera L., from the family, Vitaceae, is the choice species for the production of wine and therefore our target for plastid transformation. All chloroplast derived regulatory elements and sequences included in the vector thus originated from this species.
AFRIKAANSE OPSOMMING: Die genetiese inligting van plante word gevind in die kern, die mitochondria, en die plastiede. Die DNA van plastiede bestaan uit veelvuldige kopieë van 'n ~ 150 kb dubbelstring, sirkulêre genoom van prokariotiese oorsprong. Die genoomekwivalente van plastiede in hoër plante is 'n aantreklike teiken vir genetiese manipulering, aangesien die hoë genoom kopiegetal per organel dit moontlik maak om gereeld hoë vlakke van proteïenuitdrukking te verkry. Hierdie proteïene word tot die plastied beperk, en die ooreenstemmende transgene word in die meeste plante sitoplasmies oorgeërf, sonder die oordrag van DNA deur die stuifmeel. Plastied transformasie behels die uniforme modifikasie van al die plastied genoomkopieë, 'n proses wat deur homoloë rekombinasie en die nie-Mendeliese segregasie van plastiede tydens seldeling gefasiliteer word. As gevolg van die gemeenskaplike genetiese komplement, vind aanhoudende interen intra-molekulêre uitruiling van plastiedgenome plaas. Dit maak die setel-spesifieke integrasie, via homoloë rekombinasie, van enige stuk DNA wat deur plastied teikenvolgordes begrens word, moontlik. Vir die verkrying van homoplasmie, waar alle genome getransformeer is, word die insluiting van 'n plastiedspesifieke selekteerbare merker benodig. Seleksiedruk wat die vermeerdering van die getransformeerde genoomkopieë bevoordeel, en die lukrake segregasie van plastiede tydens seldeling, maak dit moontlik om genetiese stabiliteit en uniformiteit van die genoom te verkry. Dit kan op sy beurt tot die verkryging van 'n volledige transplastomiese lyn lei, waar alle aanwesige plastiedgenome transgenies is, en wilde tipe genoomkopieë geëlimineer is. Die prokariotiese aard van die chloroplas genetiese sisteem maak die uitdrukking van veelvuldige proteïene vanaf polisistroniese mRNAs moontlik, wat die toevoeging van volledige operons in 'n enkele transformasie toelaat. Uitdrukkingskassette in vektore bevat dus enkel regulatoriese elemente van plastied oorsprong, gene wat kodeer vir selekteerbare en sifbare merkers, asook een of meer gene van belang (teikengene). Voor elke koderingsstreek, is daar ook 'n toepaslike translasie beheerstreek om doeltreffende translasie vanaf die polisistroniese mRNA te verseker. Die funksie van 'n plastied transformasie vektor is om die oordrag en stabiele integrasie van transgene in chloroplasgenome van hoër plante moontlik te maak. Die uitdrukkingsvektor wat in hierdie studie gekonstrueer is, is spesifiek vir die transformasie van die druif chloroplasgenoom. Vitis vinifera L., van die familie Vitaceae, is die voorkeur species vir die produksie van wyn, en daarom die teiken vir plastied transformasie. Alle chloroplast-afgeleide regulatoriese elemente en volgordes wat in hierdie vektor ingesluit is, het huloorsprong vanaf VUis vinifera L.

Повний текст джерелаConstruction is one of the most polluting sectors of industry, and this is why developing sustainable building materials is of world-wide interest. Earth is being increasingly studied as a building material because of its low environmental impact and its abilities to regulate indoor moisture and to improve the building occupants' comfort. Plant aggregates and fibers have been incorporated into the earth matrix for thousands of years to enhance its performance, but scientific studies began quite recently. Nowadays, the addition of renewable resources can be achieved with agricultural by-products, thus allowing carbon dioxide to be captured. As part of the Bioterra project funded by the French National Research Agency (ANR), this thesis has the objective of contributing to the development of earth-based materials containing plant aggregates that can be used in bricks. After an extensive characterization of the different plant resources, namely barley straw, hemp shiv and corn cob, a comparative study of the use and durability properties of the composite materials is made. A survey of the production and use of bio-resources in France showed good availability of the resources studied in the present research, although they are primarily used as human food and animal litter. In the experimental tests, a decrease of the mechanical strength was observed with the addition of plant aggregates. However, the ductility of the bio-composites increased. Thanks to its elongated shape, straw is the plant aggregate that gives the best results. Concerning hygrothermal properties, thermal conductivity is reduced and the vapor sorption capacity is slightly increased. Nevertheless, earth alone is very permeable. The addition of plant aggregates thus brings no benefit concerning the apparent water vapor permeability. Finally, plant aggregates improve some durability criteria, such as impact or erosion resistance, but limit abrasion resistance. With regard to fire, bio-composites are still not combustible, even if they contain a significant quantity of lignocellulosic matter. They are, however, transformed with firing, when the earth is fired and the plant material smolder. Lastly, the study on microbial growth contributed to the development of an experimental methodology. The incorporation of straw seems to facilitate mold growth in comparison with earth alone. However, proliferation appears only in the worst conditions: for material subjected to a temperature of 30°C and a relative humidity of 93%, after inoculation with Aspergillus brasiliensis strain. To summarize, the addition of different plant aggregates in an earth matrix improves some properties but deteriorates others. The formulation of a composite material (particularly the nature and the content of the plant aggregate) will thus depend on its intended use in the building. Therefore, a compromise has to be found among the different properties

This case is a description of the process of a plant construction and the situations that a project manager may confront during it. Under the affects of various social environment and organization, the members of the Changhua Office have had to worry themselves with the uncertain future of their employment period. Given the more than three years of hard work, the company had come to admire the performance and accomplishments of the Department. Due to the variation of the external environment, the company need to improve the capacity issues for the production, the ideal to build a plant has finally come true. It is a very valuable experience for anyone to be a project manager assigned the responsibility for a plant construction. From the perspective of a third party, a project Manager seems to hold a high position, responsible for all resources, and ultimately holding an abundance of power. However, a project manager should consider thoroughly whether he could do well on the project planning, organization, leadership and control during the plant construction after he decide to accept the assignment. The project manager is able to deal with a group of people with different professional skills and live with different life culture and is able to organize them into a whole team to achieve a single goal. To reconcile the conflict between people in team and make them work together as a team through the skill of the constant communication. While the conflicting storm is keeping come in, the project manager should make the proper decision when it’s needed and leads the team come through the clutters and difficulties and conquer the risks ahead. The most important mission and responsibility for a project manager is to ensure the project runs to maximum effect under the limitations of time, budget and resources. However, one can only fully understand this when you actually undertake such a large responsibility.

In order to face global market environment, the domestic oil refining/petrochemical manufacturers need globalization as well as keep roots in Taiwan. In past decade, there are several large refining/petrochemical construction projects in Taiwan. Therefore, construction engineering company must actively cultivate global logistics, use modern information and technology integration-driven plant construction mechanisms, and strengthen its core competencies of plant construction in order to compete with other international construction companies. Construction site safety has become a very important issue in recent years. However, the reasons of incident occurrence are often overlooked and result in the loss of life and property. Hence, construction engineering company must develop a site safety management system to effectively reduce the risk of accidents. This study selects people who are working in relevant area of site safety in the domestic refinery/petrochemical construction projects as the research object. A survey method is used in this study to investigate their point of view in the following of dimensions: “personal safety awareness”, “safety culture and management”, “workplace facility and environment”. The result shows that most of respondents are highly agreeablethe with the questions in the above three dimensions.

Gasified technology has been widely valued from 1990. And it has been a trend of development from 2005 to union electricity generation and the multiplex application. Coal Gasification Technology is applied widely. It may not only be used for making Synthesis Natural Gas(SNG), the ammonia(NH3) and Synthetic Gas for the tradition chemical product and the fuel, but also may couple Integrated Gasification Combined cycles (IGCC) directly to obtain generating system of the high fever efficiency. It has lower environmental pollution than the traditional Coal Generating set does. The lowest expectation for newly Gas Clean Generate Electric Power factories is that Gas Clean Generate Electric Power emphasizes the high efficiency more than low pollution. According to the present Gas Clean Generate Electric Power development situation, it mainly has Integrated Gasification Combined cycles (IGCC), Pressure Fluidized Bed Combustion (PFBC), Supercritical Pulverized Coal (PC) and so on, in which IGCC technology is the most remarkable no matter in the technical maturation, the energy efficiency, and the environmental protection. It also has gradually become most useful new electricity generation technology. Taking advantage of the coal to transform into the pure energy has been striven to be the first important development topic for the advanced countries invested large research and development resources. Because Integrated Gasification Combined Cycles (IGCC) has the superiority of the energy efficiency promotion, the high potential and the remarkable environmental protection, it will be the trend for the future and be conducive to improve the high carbon electricity generation structure in our country at present. However, there are less pure IGCC plans at present in our country. This research focused on extracting the main decision factors and developing the hierarchy in the decision making of building up an IGCC factory which leads to the reduction of investment cost, construction period, operation and maintenance cost. It will be able to conform to the law of development documents as well. Our research established the evaluation hierarchy and the decision model with rational index and weightings of building up an IGCC factory for the electrical industry. Through the proposed AHP hierarchy, a better development of electrical industry is expected.

Construction project generally includes a set of activities. Precise information about the activity duration is seldom available, due to the complication, long range and less duplication. It is not suitable to use crisp value to evaluate the project scheduling. Fuzzy PERT has been developed to solve the project completion time problems for uncertainty of activity duration. But unfortunately there are still many difficulties to apply. The main difficulties are: (1) The fuzzy number comparing methods used to determine the earliest startting date of each task are different. (2) Using fuzzy substraction method to compute the fuzzy latest dates, fuzzy number extension and unreasonable negative value will be happened. (3) Assuming activity durations well known in literature are unreasonable for real world project management. (4) There is no appropriate project risk level index for decision makers to make a decision. This paper deals with above difficulties and proposes modified methods in fuzzy PERT. The modified methods include: (1) Propose Max α-level cut method to compare fuzzy number, in order to determine the reasonable earliest startting date of each task. (2) Using fuzzy algebra method instead of fuzzy substraction method to compute the fuzzy latest dates. (3) Activity durations are available from task volumes and capacity of resources. (4) To create an appropriate project risk level index for decision makers to make a decision. In this paper presents an algorithm model, which is feasible proved by actual example and simulation cases. It can aid decision makers to evaluate construction project completion time and project risk while bidding.

Scheduling is a very important domain in production management. It can be used for planning a series of jobs or activities as well as planning time schedule of a machine and equipment. Therefore it is considered the best method for distribution of limited resource. A construction of a good scheduling system not only can increase the rate of the use of a machine and equipment but also help people to finish jobs on time in order to meet their customers’ demand and increase the profits and abilities of their companies. The parallel-machine scheduling problem will be caused when there are two or more machines to work with the same process. The parallel-machine scheduling problems are commonly found in plastic injection process. Plastic injections parts are produced by using many parallel-machines to achieve the required output. The subject of this research is to provide a construction of a scheduling system of plastic injection plant of the shoes industry and to solve this complicated scheduling problem by using heuristic algorithm and computer.

Повний текст джерелаIn Nuclear Power Plant operation, Nuclear Safety is paramount to protect the personnel, public, environment and the plant from the potentially harmful effects of nuclear radiation. This is evidenced by nuclear accidents such as Chernobyl and Fukushima. The ability to ensure that the design of a nuclear plant remains aligned to the design intent of its safety systems and components is fundamental to nuclear safety. This responsibility lies with the Design Authority appointed in the operating organisation. With many nuclear power plants being built around the world in countries which have not operated nuclear plants previously, it is imperative that these organisations are supported with guidance on what is needed to establish the Design Authority function. The lack of comprehensive industry guidance has led the researcher to the primary research question: What elements should be considered for the effective establishment of the Design Authority function at commercial operation of a New Nuclear Power Plant Construction project? Based on a comprehensive literature review of existing international industry regulations, standards and guidance documents, followed by a survey of internal nuclear experts, the critical elements for establishing the Design Authority function were identified. The survey covered existing power plant operations and nuclear build projects, as applicable, in countries which included the, United States of America France, United Kingdom, South Korea, Canada, Romania, China, South Africa and. United Arab Emirates The study identified the fundamental elements in establishing the Design Authority function as; acquiring the design knowledge and skills to execute the function; securing the plants design information; and establishing and ensuring compliance to a configuration management process

Company F is a well-known petrochemical group in Taiwan. In the early stage of the company founded, the engineering manpower is not sufficient for construction project. All construction projects generally execute with a whip style organization. Into the growth stage in the 1970s, the manpower of the engineering department has been quite adequate with professional skill. In that time, the whip-style organization of plant construction project change to function-style organization model. After the start of the 1990s, a large petrochemical expansion project was start; more than 10 plant construction projects must be executed at the same time. Company F allowing the use of a whip-style project management model to save project manpower. In last 10 years, both of two project organization modes were used when the petrochemical expansion coming to an end. According to the past experience, part of project has been quite successful and part of project failing in schedule, quality and cost control. In this thesis, according to individual construction project practices evaluate the management procedure and mode. By following the engineering management standards of company F combined with the basic concept and theory of project management, supplemented by practical engineering experience to identify the key success factor for project management.

As Taiwan’s high tech industry has made great developments within the past 20 years, I have participated in the design and construction management of numerous high tech fabrication (fab) plants. The fierce competition, huge investments, and rapid changes that exist within the high tech industry necessitate extremely tight schedules for fab construction. Thus, in order to achieve superiority in the market of fab construction services, speed is very important. In my experience, we have assisted clients with equipment setup in addition to constructing their fab plants in order to help them advance/meet their proposed plant test run date. Gradually, the traditional construction method of separating design and construction will become inadequate at satisfying the time restrictions of high tech fab plant construction; the study and use of alternate methods will be necessary. This technical report aims to evaluate such innovative methods by taking into account reviews of existing literature, Fast Track Construction and Design-Build Construction case studies and personal experience. One must consider factors of work scope, management style, company organization, and design-construction integration and coordination while attempting to reduce the design and construction time required to build a fab plant. The report intends to serve as a reference to the construction industry and high tech client companies on high-tech fab plant construction and management.

The features of High-tech factory construction project include tight construction duration, numerous mobilization, high-volume of materials, and complexity of interfaces. In the overall project, the cost and the progress of construction are seriously affected by transmission of interface information. According to Lean Construction Institute theory, due to inefficiency, errors, delay, and communications, 30% of the construction cost are wasted on manpower and material. Therefore, in order to reduce waste and risk in project planning and construction , this research intends to use 4D visualized model to facilitate the transmission interface of information. The purpose of this research aims to apply 4D visualized technology for facilitating construction site management and in line with the theory of Lean Construction concepts. The research project focuses on construction management, and its research process is as follows: the first step is to establish a Work Breakdwon Structure (WBS) based on 4D image, known as Object Block Work Breakdown Structure (OBWBS), which is advantageous to define images in the working items operated by the contractor of the project. The second step is to plan the construction process of contractors. Finally the images classified by OBWBS are linked to construction project process and carried out 4D simulation. Consequently, this 4D visualized model can be applied to simulate working process for various contrators work. Meanwhile, it can be used to verify how far is between the current stage and the ultimate result. The model can surely improve communication and efficiency of decision making.

Petrochemical industry is one of the most important primary industries in Taiwan. Products of this industry comprise headstream basic parts, middle stream medial parts, and down stream processing wares. According to statistics of Industrial Development Bureau (IDB), the total production value of petrochemical industry has exceeded 12000 hundred millions NT dollars, with the percentage standing at approximately 23% of the whole manufacturing industry. Therefore, it affects the domestic economy enormously. In recent years, global demand on petroleum chemicals is growing. The ongoing attempt to carry out the tenth five-years plan from the mainland China specifically and especially stimulates the rapid growth of the petrochemical industry. Building a petrochemical industrial park is becoming the priority construction in between across the strait. Currently, to ensure the plant-building efficiency, most petrochemical plant constructions adopt the design-build mode. In the past, on the contrary, since there was no formal and strict criteria for plant builder selection, quality of builders differs tremendously, producing flaws in certain design cases and construction quality, making untoward operations, and creating tremendous cost in maintenance and resulting in huge waste. In light of the unsuccessful past domestic plant-building experiences, how to select an excellent and reliable design-builder is key for petrochemical plant to finish construction without a hitch.. This research focuses on plant-building design-builder selection criteria for the petrochemical industry. This study analyzes in depth all relevant documentations, either domestic or abroad, regarding scholars, institutes, and public projects, and other related writings concerning plant-building practices from a certain petrochemical firm in Taiwan to discuss the correlations of petrochemical plant-building factors, builder selection factors of public projects, and design-builder selection criteria for the petrochemical plant construction. Using the correlations established, expert interview is conducted, questionnaire designed, and factor analysis conducted to establish to build criteria hierarchy. Then, the Analytic Hierarchy Process (AHP) is utilized to determine each criterion weight and to establish a strict but feasible selection criteria mechanism. The results of this study serve as a reference for managers of petrochemical industry in choosing the best plant-building design-builder.
