The hospital manager is studying and evaluating some options of Blood bank services to be more efficient as he has three options; each one is different in terms of cost, benefits and efficiency, and he is trying to evaluate which one will most suitable for making this service more efficient our role is to develop a multi criteria model for his problem and options he has, to help him taking the right decision Utilizing the multi attribute value analysis supported by V.I.S.A software.

Problem structuring:
The checklist cause criteria, alternatives, uncertainties, stakeholders and environmental factors or constraints will help to ensure that all the important facets of the problem have been considered. Expanding briefly on these aspects in relation,

Stakeholders: is the hospital manger however there are some other stakeholder including as the senior medical staff and other department managers Alternatives: there are three alternatives:
1. Keep the Blood Bank as it is without changing. And we will call it Option A 2. Expand the Blood Bank to content more blood supply. And we will call it Option B 3. Implementing an IT inventory system with automatic supply order. And we will call it Option C The criteria: different between the available options.

The external factor is often considered as a source of uncertainty, as traffic or weather problems is a factor to be taken into consideration

Building Value Tree
For this we will use the VISA to justify our suggestion with considering on Managerial point view, Analyst, Facilitator, Finance, and Customer service. In this VISA we will consider three main aspects and there are sub criteria: * Cost:

* Logistics / Transportation Cost
* Capital Cost
* Maintenance
* Operation Cost
* Funding
* Management
* Stock control
* Over Stock
* Stock Deficiency
* Delivery Frequency
* Predication of requirement /...

...Quantitative Research MethodsQuantitative means quantity which implies that there is something that can be counted. Quantitative research has been defined in many ways. It is the kind of research that involves the tallying, manipulation or systematic aggregation of quantities of data (Henning, 1986)
John W. Creswell defined quantitative research as an inquiry into a social or human problem based on testing a theory composed a theory composed of variables, measured with numbers, and analysed with statistical procedures in order to determine whether the predictive generalisations of the theory holds true. (Creswell, 2003)
On the other hand, another author defined quantitative research as the collection of numerical data in order to explain, predict and/or control phenomena of interest. Quantitative research is explaining phenomena by collecting numerical data that are analysed using mathematically based methods (Aliaga & Gunderson, 2000)
Quantitative research can also be said to be a research based on traditional scientific methods, which generates numerical data and usually seeks to establish causal relationships (or association) between two or more variables, using statistical methods to test the strength and significance of the relationships (A dictionary of Nursing, 2008)
Simply put, quantitative...

Quantitative research collects numerical data through surveys, questionnaires, and polls. Quantitative research main purpose is to find the relationship between two variables. According to Babbie (2010) a descriptive study establishes only associations between variables while experimental defines the casualties (pg. 1). The data that is collected from the research is usually used for bigger representation of a population. The data can also be repeated if it was considered to be very accurate and reliable. Every part of quantitative research is scrutinized very carefully before the data is actually collected. The data that is collected is always in a statistics form or number form. Quantitative research can be used to investigate causal relationships, tell the future, or generalize concepts more widely. According to Babbie (2010) to the main purpose of quantitative research study is to classify features, count them, and construct statistical models in an attempt to explain what is observed (pg. 1). There are four approaches under the Quantitative research and they are descriptive research, correlation research, causal-comparative research, and experimental research.

...The Principal as a DecisionMaker.
A school principal is an education administrator who oversees the day to day operations of the school. He or she offers instructional leadership to everyone in the school. These include the administrative staff, faculty and students. The role of a school principal is that of a guide to the students as well as a disciplinarian. There is much more to the position than that, however it is a complex job that offers numerous challenges, each day different from the day before.
The principal acts as the manager as well as the highest decisionmaker of the entire institution. Although school policies can be dictated by the principal, he or she does not have ultimate authority in that regard. The principal must, after all, listen to the needs and demands of the school board, parents and students. To this end, the principal must regularly meet with parents and address their many questions and concerns before taking any sensitive decisions on issues relating to them.
Decision making is one of the most important roles of the school principal. Every administrative act, whether it concerns students, programmes, staff, services or resources requires making decisions. Decision making precisely is an act of choice between alternative courses of action. To be able to decide on what action to take on any administrative matter, the school...

The Coca Cola Company

The History of Coca Cola
The 125 year old Coca Cola Company currently ranks 70th on the List of Fortune 500 Companies for 2011. Coca Cola began in 1886 when pharmacist John Pemberton in Atlanta, GA, sold a caramel colored mix that was combined with carbonated water and sold for $.05 cents a glass at Jacobs Pharmacy. The pharmacy sold approximately 9 glasses the first day totaling $.45 cents a day average. After John Pemberton passed away in 1888 the company rights were acquired by a business name named Griggs Candler for $2,300 (The Coca Cola Company, 2011). Candler led the way for the innovative product to become a business. He began promoting the product on everyday products so that the logo was everywhere and the aggressive tactic worked. The demand grew so quickly that there three production facilities were up and operating within 7 years. By 1920 there were over 1,000 bottlers of the product and in the 40’s the president helped to lay the international groundwork for the company to begin doing business overseas and ensuring that a Coke was available to many for a small price.
Currently the company now has a brand list that exceeds 500 with 3,500 plus beverages. This company has nearly 140,000 employees and operates in more than 200 countries (The Coca Cola Company, 2011). On average a 16oz cola sells for $.99 cents. In 2011 the company...

...theory explained crime as a free-willed choice where criminals are rational decisionsmakers. There are not just one theory to fully explain and support criminal behaviours but various theories working together to explain such phenomenal a great example would be in the case of Ted Kazynski. During 1978 and 1995 Ted Kaczynski left many packages which contained explosive material for people to find causing injury and in some cases death. He also mailed a number of packages all over the United State of America to university professors and people involved with computers and technology within the country (Johnson, 1998:1-4). Ted Kaczynski’s interest in explosive materials can be traced back to when he was still in High School where he used a science class to build he very first explosive device a pipe bomb. There can be many theoretical schools of crime causations that we can used to explain why Ted Kazynski committed such crimes.
In the Classical School Theory it was noted in Kaczynski’s statement was that he felt disturbed by society in terms of “overcrowding, dissociation from nature, social conformity, rapid pace of technological change, consumerism…corporate domination” (Unabomber: Ted Kaczynski, 2). This a clear case where perhaps Kaczynski believed if he rid the world of these people involved in technology things might return to normal for him. Here Ted Kazynski is rationalising with his decision to commit the crime where he...
