1. Two forms of decision that is not structured and unstructured. Why top level more associated with unstructured decisions, while managers have more contact with the bottom of a structured decision?
       
    Difficult decisions with the response to a structure that can provide for him. A more structured decision can be planned or reserved in advance, while the decisions that are not structurally higher can not be so. Decisions that can be said terprogramkan structured, in the sense that the decision rule is not ambiguous (double) will be determined later. The term is not important that decisions be automated, Kaputusan terprogramkan said to be unstructured. Keterstrukturan terprogramkan decision to maintain a daily routine and often repeated; unstructured decision making rare and non-routine decisions will be easier harian.Beberapa right into this classification, but many decisions are more or less structured and some elements terprogramkan and some do not.
Terms structured information systems for decision is a procedure that is more clear and not vague for the specified input data entry, validation procedures to ensure complete rectification and input, processes the input by using the decision logic, and output from the decision-wired into a form useful for action. A useful output will definitely be used and consists of data to assist the recipient to assess the proper decision.
In many cases, impossible to define a decision procedure or decision rule to handle all possible situations. In this case, the decision rule is written to use the most ordinary situations, and situations are not unusual or extraordinary that no man put a call on decision makers, usually one with some special knowledge.
Unstructured decision before the decision procedure can not be denied one because the decision is too rare to justify the value of an organization that prepares a decision procedure (though perhaps some of the program) or because the decision process is not well understood or changed as well to give a decision procedure which remain are not be denied. The requirements for making a decision support unstructured data and assessed on a variety of analysis and procedure requirements incomplete data known previously, then the search for data to be followed while a search request. An interactive decision support system with a common answer is the support and the ability to analyze information systems are suitable for unstructured decision-making.

2.What is a Decision Support System, Explain your answer with examples in case you know?

   Decision support system is a computer-based system intended to assist a manager in making a decision to utilize data and models to solve unstructured problems. Decision support systems can also be regarded as an information system that uses decision models, databases, and the thinking manager himself.
Case in point:
A manager at a trading company wanted to create a system that will assist him in determining the operating costs in a period, then appeared in his mind some questions such as:
1. What exactly will I get from these systems?
2. If the cost of the prototype is Rp.X, if I can accept those costs?
Basically there is an answer to that question that allows the manager to handle, among others, by developing a system based Decision Support System (DSS) is the manager can answer the business problem in a way helped in enhancing better decisions in the planning, communication, and to supervise its employees, and with this step a manager can also save time in doing his job to make a decision.
Here Managers also faced with several alternative solutions, among others, "If the prototype can only do two of my three operational objectives, at a lower cost than RPX, whether I will use the system or develop in order to meet my needs?".
Here it can be concluded that the value and costs kept separate and not equated. This applies only if the cost is maintained. From case studies of decision support systems is seen that to be able to do impelementasi analysis values, in most organizations, the cost must be below $ 20,000.
