****Please Please No hand writing ,And answer all the questions not part of them.THANKYOU in advance
1
It is usually difficult to obtain an explicit statement of the organization's goals.
• The decision maker may change the importance assigned to specific goals over time or for different decision scenarios.
• Goals and sub-goals are viewed differently at various levels of the organization and within different departments.
• Goals change in response to changes in the organization and its environment.
• The relationship between alternatives and their role in determining goals may be difficult to quantify.
• Complex problems are solved by groups of decision makers, each of whom has a personal agenda.
• Participants assess the importance (priorities) of the various goals differently

Revising models to eliminate too-large sensitivities
• Adding details about sensitive variables or scenarios
• Obtaining better estimates of sensitive external variables
• Altering a real-world system to reduce actual sensitivities
• Accepting and using the sensitive (and hence vulnerable) real world, leading to the continuous and close monitoring of actual results
3 A manager might perform what-if analysis to find out what will happen if a particular action is taken. A manager might also perform what-if analysis to try out several alternatives, choosing the one that works out best.
4 Goal seeking: The goal seeking is a process of the evaluating the inputs values which is essential to accomplish the preferred output level. It is also known as the backward solution approach.
Example: • How many nurses are required to minimize the patient waiting time in emergency room to below 15 minutes?
Reason for using the goal seeking by manager: The reason for using the goal seeking by manager is given below:
• Manager might utilize the goal seeking process to discover the decision variable which permits to meet the predetermined condition.
• Manager uses the goal seeking to accomplish the preferred goal by evaluating the input values.
• For instance, manager wants to determine the budget for advertising the business. That is, it will reach the cost for house “A” is not above the $X amount.
