SIGMA: A new era in the business world
SIGMA is based on the simple and intuitive Event Graph approach to simulation modeling. The SIGMA project evolved from doing simple event graphs on personal computers into implementing a powerful and practical method for simulation modeling. This Simulation Graphical Modeling and Analysis system is an integrated approach to building, testing, animating, and experimenting with discrete event simulations. Thousands of firms in the transportation, manufacturing, and even the gambling industry have been benefited from using this simulation software to improve their logic and production systems.
The steady increase in airport traffic has lead air transport managers to think a new design and management of Airports for the future. It appears to them that all aspects involved in the airport should be redesigned with the newly developed technology, especially the traffic control in the security check point. The problem with this traffic control is the long wait time in the check in point that is caused by the complex security check(luggage, body, etc). Simulation techniques can be helpful in improving this system. A group of engineering students from UC Berkeley use the SIGMA to model the whole traffic flow between the security check point and the check in point. Then, they found that, besides the complex security check, the distribution of passengers' check in time is another factor that causes the long waiting line in the check in counter. To make improvement to this system, these engineers' craft out a new check in procedure which redistribute or rearrange the check in time for each passenger. For example, passengers have flight during the busy time may be suggested to schedule a specific check in time the night before departure. By doing this, the passenger is placed in a virtual queue in the check-in line and his wait time for check in should be no more than five minutes if he commits his appointment. This idea gains its support from the SIGMA simulation report which shows the average wait time in the check-in point declines significantly.
Capitalizing the manufacturing machines has been known for the thumb of rule for success in the semiconductor industry. Unlike other manufacturing plants, the fab usually operates 24/7 to maximize its production volume. In addition to this, any minor mistake or mishandle in the production process may lead to loss of millions of dollar. In order to guarantee the production plan runs smoothly, the use of SIGMA may be helpful.

“What time should we leave? Two hours in advance? Three? Four?” Millions of people ask these questions each year before boarding a plane. Between driving, security, walking to the gate, and getting settled, boarding a plane exhausts travelers. But out of all of these different activities, one frustrates and restrains travelers the most: TSA security. People ask why they need all this security, complain about the inconvenience it causes, and ultimately annoys people to no end. Created after 9/11, Transportation Security Administration, or TSA, nationalized airport security, increased screening duration, and supposedly increases security on flights. However, statistics say these added security measures never come to fruition and potentially cost more lives than they save.

At many airports across the country, passengers are sharply greeted with the hassle and headache generated by the long security lines. Many travelers complain of the continuing list of rules they have to observe and how they seem to get persistently worse. The government’s solution to the hassle and headache is full-body scanners. The government claims these full-body scanners are faster to go through versus the traditional metal detector, detect weapons and bombs easier, and reduce the stress of the long security lines. In the past, airport security has not been fully successful in protecting the country from terrorists. As a result, many terrorists without being detected are escaping and are free to pursue their assault on America. Having full-body scanners will allow for less time in security, easier detection of terrorists, and will help to protect the United States.
Challenged by an old, obsolete airport, the city of Denver decided on not only doing an expansion but ultimately building a fully dedicated facility in an entirely new location. Twice the size of Manhattan, the airport was to be the largest in the United States and was specially designed to handle concentrated hubbing traffic (Montealgre et al, 1996, p.4). The master plan encompassed a fast tracked build-design scheme that called for utmost operational efficiency which would consequently attract large airlines to choose DIA as their main Southwestern hub (Nice, n.d.). Dominance of the DIA would fuel an economic boom in Denver, but for this to take place—a fast passenger turnover would be required, leading to the perception that they had to implement an airport-wide automated baggage handling system in spite of the known risks. This critical piece of the airport wou...
Government-operated system of administering airport security, versus privately owned and operated, contracted airport security organizations have proved to be less efficient and effective for airports, passengers, and airline companies in the aviation industry. Factors such as the September 11th terrorist attacks have resulted in the creation of the Transportation Security Administration as it is been established by the government to control all airport security. A look into how San Francisco International Airport’s ability to remain secure while utilizing a private security company under contract with the federal government has shown to be efficient, cost-worthy, and effective for many airports. Returning to privately operated airport security throughout the country while regulated by the Transportation Security Administration shows great possibilities for all airports that want to follow suit.
The gate agent’s job appears to be a balancing act between the safety of each passenger and the inconvenience of the process they must undergo to ensure that safety. Agent Ludo Sanchez was part of the first wave of those hired after the Trade Center event. He applied for the TSA position out of a sense of patriotism as soon as he became aware that there was a need. Also, in Sanchez’s defense, on the day of the incident, as soon as he was notified that his area had been breeched, he immediately began “the standard procedures for securing the area, and sealing the terminal from further passenger traffic” (p. 6).
Understanding a few areas where technology can be very beneficial is beneficial. Specifically, security measures or screening methods need to be reviewed. Since 9/11 many different areas have changed in the way airports conduct business. Security is always a serious concern and needs critical thinking. Airport security is not an area to lose focus on when it comes to security processes needed. One area needing some prevention and is a concern is the insider threat.
Sigma is known for its multinational clientele (Ferrell & Hartline, 2014, p. 461). The area in which Sigma marketing targeted was very much limited in how the area served only covered a radius approximately 30 miles around the city of Streator and had a number of major manufacturing plants that were potential users of substantial quantities of printing (Ferrell & Hartline, 2014). Sigma provided quality and service despite the limited uniqueness in the company.
Hkust and Hkust (2002) expressed that limited research studies have been conducted to determine how service waits can be controlled. To control the time customers’ wait in line,
Airport security has changed since September 11, but this change is not always a good thing. One of the major changes that has taken place in airport security is more searches are being done. As a result of increasing the number of searches taken place, more people have their privacy rights violated. Another result of the increase of airport security is that less peopl...
One essential part of the airport system is security. Today, security is a major priority that airports must administer strictly. Due to the recent terrorist attacks on September 11, 2001, airports along with airlines want their customers to feel safe.
The airline’s Wi-Fi-enabled flight is one of the most satisfying features of the customers (Belobaba, Odoni & Barnhart, 2009). The feature will serve to restore the lost glory of the Asiana airlines. The ethical issues involved in the customer experience aspect include the need for creation of a favorable environment through the provision of the woman only lavatory is a crucial ethical aspect, which ensures that the women are afforded the respect they deserve. In-flight connectivity is one of the greatest innovations many other airlines are trying to realize since it makes the experiences memorable. The air transport framework is a major financial complex, which incorporates aircraft, which execute traveler and cargo movement and air exercises, all aeronautical designing, specialists, which give operation of aircraft. The abnormal state of flight security of innovative flying machines depends both on the aircraft, and on capability and preparing for a team, which controls the aircraft. The utilitarian effectiveness of a aircraft is dictated by mechanical flawlessness, dependability, controllability, mobility, the furthermore high viability of an airframe, the motor, and the
The terrorist attack of Sept 11, 2001 significantly changed the landscape of air travel. Congress put in place mandates to screen all checked baggage and improve passenger screening procedures. The Transportation Security Administration (TSA) was chartered to oversee these changes. The major obstacle was old antiquated equipment that was unable to handle the demand which resulted in a significant delay in time it took to process passengers. With the recovery of the airline industry since the attack the challenge is how passengers move through the airport quickly and efficiently. Through the history of air travel there have been many initiatives attempted to improve the passenger experience. The three I will focus on are the mobile lounge concept implemented in 1962 with the opening of Dulles , and the newer concept of Fast Travel initiated by the International Air Transportation Association (IATA) and the so called “security checkpoint of the future” also being tested by IATA (Engle, 2011).
Fortunately, during under-graduation, I got an opportunity to detect the optimum path of a process through my project “Design and Development of PCB Dual Head Drilling Machine”. Additionally, I became aware of a new subject called Six Sigma which aided me in intertwining new optimization techniques into my project to make the process effective. I optimized the creation...
