Techniques for roadway tunnelling Research Paper

Techniques for roadway tunnelling - Research Paper Example The tunneling process usually starts with the excavation of the area in which the tunnel is to be created. After the determination of the main functional requirements, tunnel designs are usually drawn based on the various factors identified. The tunneling technique and approach to be used in a project must always be selected in the initial stages of the planning phase so that the team is able to understand the procedures involved and the possible risk factors that it will have to deal with so as to achieve the intended objectives. Several techniques have been used in roadway tunneling. According to Bartà ¡k, Hrdina, & Romancov (‎2007) the technique used in the construction of a tunnel is normally determined by several factors. They include the shape of the tunnel, tunnel length, available resources and technology, environmental constraints and the geographical features in the area where the tunnel is to be constructed. The main concept in majority of the roadway tunneling techniques involves the sequential or full length excavation of a road segment followed by subsequent construction of the passage. In most instances, drainage, ventilation and support will be required in the tunnel. The final stage of the process entails considering environmental issues such as the planting of tree and the reconstruction of secondary roads upslope. Conventional roadway tunneling is the construction of underground pass ways and openings of any shape through the use of cyclic construction processes (Bartà ¡k, Hrdina, & Romancov, 2007). Hashemi (2013) states that conventional roadway tunneling is normally done by carrying out cyclic process in different stages. The process can however be grouped into three main steps. The first stage is the excavation of the soil and rocks using different methods like mechanical excavation, drilling and blasting. This is then followed by mucking. The

Pppp - Coursework Example Steven Chu, for instance, points to the breaking up of the great ice packs, which will ultimately result in a notable rise in sea level. Unless climate change is halted, this rise will submerge some parts of the earth completely and ultimately cause the death of living things in the coral. The negative impact of greenhouse gases is attributed to global trends in the demand for and supply of energy (S. Chu; Chu and Majumdar). According to Chu (6), â€Å"†¦between 1971 and 2000, the total use of energy doubled and is expected to triple by 2020†, while oil and gas reserves are diminishing by the day. In order to resolve this crisis, many options have been proposed that call for concerted research on the use of bio-based fuels (such the use of grain to generate ethanol), and nuclear fission as well as research on how best to harness inexhaustible energy reserves such as solar and the wind, as well as photosynthesis (Chu and Majumdar; S. Chu). In its 2004 report titled Ending the Energy Stalemate, the National Commission on Energy Policy has made many recommendations with a view to averting the crisis. I outline below some of the recommendations with which I strongly agree. I strongly agree with the recommendation to develop energy technologies for the future (The National Commission on Energy Policy). As we edge closer to the depletion of natural oil resources, it is imperative that we explore new technologies to complement or replace the exploitation of natural oil deposits. As such, I agree that there is need for the government and private sector to increase funding for energy research, and to also provide incentives that will spur production of alternative fuels for the transport sector. I also agree strongly with the recommendation to strengthen critical energy systems. This is because crucial energy systems, including the electricity grid, provide a environmentally friendly energy options, especially if these are generated using inexhaustible

Research W. Edwards Deming's 14 points and identify at least one of Essay

Research W. Edwards Deming's 14 points and identify at least one of those 14 points which resonates with you personally - Essay Example His efforts caught the attention of the Japanese emperor, who gave him an award for his role in the country’s industrialization (Anderson, 12). Upon returning in United States of America, Deming wrote a book by the title Out of a crisis. This book was published in 1982, and it outlines 14 points which if used in the United States manufacturing sector, then there will be an industrial boom in the country. The 14 points advocated by Deming may seem to be a bunch of radical ideas; however, to effectively understand these ideas, it is important to understand Deming’s explanations of the concept of variance. According to Deming, variation was the problem that presented a great threat to the manufacturing industry of United States of America. Deming reasoned that if there was a variation in prices, times of delivery, work ethics, then companies were wasting their resources (By, 23). On this basis, Deming identified 14 points of management that people and companies ought to fo llow. These points are (Deming, 7); 1. Creating a purpose of constancy in order to improve the operations of the business organization. It is therefore important to replace the short term objectives of an organization, with long term goals. 2. Adoption of the management’s new policy. ... 4. The industry should identify a single supplier for one product. This is because many suppliers’ will always produce different quality of products, and this leads to a variation of the product under consideration, and this results to a variation of the products supplied. 5. There must always be a need of improvement, and this is in regard to reducing variation. 6. On job training is a necessity if the organization wants to achieve efficiency in its work force. Inadequate training will make people inefficient, leading to an increase in variation of the products produced. 7. Deming advocates for institutional leadership. In his opinion, there is a difference between leadership and supervision. He denotes that supervision involves setting up of targets, and it is quota based. 8. The eighth principles that Deming develops, relates to fear. Deming denotes that developing business policies out of fear is counter-productive. As such, managers ought to drive out fear for them to ach ieve success in their endeavors. Fear also prevents workers from effectively serving the interests of the organization. 9. The ninth principle is in regard to breaking down the barriers that exist between the various departments of an organization. Under this principle, the idea of the internal customer emerges. This idea denotes that the various departments within an organization serve each other. They do not serve the management. This is a very central idea in TQM. 10. Deming also proposes the concept of eliminating slogans within an organization. Under this idea, the mistakes that people make, does not arise because of their faults, but because of the various processes within the organization that they are working for. On this basis therefore, it is not wise to harass

The Strengths and Weaknesses of the Structural Form Case Study - 47

The Strengths and Weaknesses of the Structural Form - Case Study Example Inter-organization relationship enables the stakeholder firms to enjoy the element of synergy and ensures stability and sustainability of the service industry. The competence of the resultant cluster goes up due to competitiveness and shared resources. This also adjusts the level of diversification in management through the combination of management skills from the partnering organization (Enz, 2009). In partnership, the importance of stakeholders depends on their contributions towards the growth and management of the organization. This refers particularly to the share proportionality of ownership, where some partners hold more shares in the organization than others. The high priority stakeholders are managed by awarding them proportionally according to their contributions. It means they receive the largest share of the return of the business. At the same time, they receive special privileges in the organization, such as powers to make critical decisions. One of the most important activities associated with strategy implementation is designing a strategy-supportive organization. Contact a hospitality organization and request a copy of its organization chart. Keep in mind that not all organizations are comfortable providing this document, and you may have to contact several firms before one provides you with the document. Examine and identify the strictest of this organization. What are the strengths and weaknesses of this structural form? If you were to change the structure, what would you modify and why? If this firm grew to twice its current size, what changes in its current organizational form would you recommend? Why? We managed to get the organization structure for Australia Fast Foods, of course after several attempts at different hospitality companies. Here we got to learn that the organization is headed by the managing director, assistant managing director, Heads of Department, senior managers and eventually the clerks at the lowest ranks.  

ISMG Essay Example | Topics and Well Written Essays - 500 words - 3

ISMG - Essay Example The supply is controlled by the weather while the demand is controlled by spikes and shifts in demand like for other manufacturers. Due to the supply being clustered in one area and the processes after harvest being too many it raised a lot of problems for the company in terms of costs. The company needed a system that could solve the problem of line utilization, scheduling, reducing inventory, transportation costs and lead time. The sales and operations (S&OP) program was adopted to help alleviate these problems. It was meant to handle problems such as unanticipated demand, shortages in supply, and production disruptions. The paper-based spreadsheet system that the company previously used became inadequate in supporting the complex nature of the business while also not meeting demands of the company. This is mainly because the company was too big and more complex while the spreadsheets relied on outdated data that required a lot of effort to analyze. The S&OP program is implemented in different stages with the first stage being scrubbing all the previous data and unifying it in one database. This step was mainly meant to ensure that all the participants of the supply chain worked together with each other and understood the other departments accordingly. This was followed by a five phase implementation program to show value of S&OP program early in the transformation. The first phase required improving demand visibility that necessitated better communication at the decision making level while also ensuring that every member of the group gained same data and each other’s goals. The program also helped in training the users of the program while also testing the scalability of the program without disrupting the company’s existing workflow. The statistical forecasts and preparing plans for price changes and promotions in future and an analysis of demand data was also improved thereby

Business Research Individual Work 1 Week 6 Essay

Business Research Individual Work 1 Week 6 - Essay Example However, sales promotions are commonly used when a business urgently needs to shorten the life cycle exhibited by a certain product or when there is the need to increase the usage of a certain product (Soguero-Ruiz et al, 2012). According to business experts who have sought to analyze the effect of different marketing strategies, sales promotions have exhibited both long term and short term effects. Understanding these types of effects is critical to any business as there is a salient need to assess the effect of the sales promotion carried out. In the specific case of a tissue manufacturer, ranking fourth in the market share, it needs to understand the potential effect of sales promotion activities. According to the plans of the company, two types of coupons are to be tested in the months of November and December. A fifty cents-off coupon would be implemented in November in two identified stores, namely St. Louis and Kansas City. In December, the company would experiment with a â€Å"buy one, get one free† coupon. In a bid to establish both the long term and the short term effects of the two coupons, the tissue manufacturer would need to carry out an appropriate experiment. Experts in this field have sought to describe effective methodologies of assessing the effects of sales promotions on sales (Magee, 2003). One of the effective methodologies that have been described is the use of data scanners in the target stores that would provide a database of all the sales of the intended brand. This methodology would be effective in the case of the tissue manufacturer. In the month of November, data scanners would be used to keep records of sales in the target stores. The same would happen when testing the â€Å"buy one get one free† coupon in December. After the data collection process, the analysis would follow. In the experiment to be carried out, the fifty cent-off coupon as well as
