The Research On Architectural Decision Making In Regard Of Architectural Efficiency

This dissertation studies the architectural planning and design process and the solving of problems during it, comes to the conclusion that how to make better and quick decisions is the key to improving project efficiency. And then puts forward the constructive "five element" system in decision making so as to make fast decisions and improve project efficiency. It is the way of systematic thinking and decision making in architectural planning and designing. The five key elements are: problem, objectives, alternatives, consequences and tradeoffs.The decision making method this dissertation studies is the systematic and rational defining and searching process of the five key elements mentioned above, puts them all into a decision table, by means of a particular method does tradeoffs out of the elements, so that it makes the decision clear and reasonable in the architectural design and planning process. Chapter two to chapter six studies the five elements in details.Define the problems creatively and make them into opportunities during the planning and design process. Chapter three introduces the method of defining problem in decision making.Search the objectives of plan and design before making decisions. Objective is the guide to decision making. It helps to search necessary information and explain the final choice; it determines the importance of a decision and the time and energy it worthwhile taking. Be careful of some traps when search for objectives, grasp the right method of objective searching and make clear the practical suggestion of every objective.Be creative in searching for possible alternatives. Chapter four introduces the key to better alternatives and the four different types of decision making in choosing alternatives. One should know when to stop looking for more alternatives.Be ware of the consequences of every decision in the design process. Describe the consequences of each alternative in a consequence table and make compare between them. Chapter five introduces the way and skills of how to describe consequences correctly, completely and accurately.Make rational tradeoffs out of conflicting objectives. Find and rule out the dominated alternative-alternative that has only disadvantages and no advantagecompared to a certain alternative. Use Equal Effect Replacing to make tradeoffs in the alternatives left. Chapter six introduces the origin, core and skills of Equal Effect Replacing, which turns complicated decisions to simple ones.
