Problem Solving Technique and Systematics for Engineering Projects
When the engineering projects and problems are approached with a certain systematic, the rate of successful solution of the problems will increase. Most engineering problems are partly solved or not solved at all because of the failure to implement this systematic approach. The steps of this system, which can be applied even in the problems of our daily life, can be listed as follows:
1.Expressing the problem
The problem is expressed, the problem, the goal and objectives are to be understood.
A realistic outline of the examined physical system is drawn. The draft should not be too detailed. However, it should resemble the actual system and all elements must be placed in the drawing. Information and notes about the items should be shown on the diagram.
3.Assumptions and Approaches
Simplifications and assumptions made to achieve the solution should be expressed. Suspicious assumptions should be justified. Appropriate values are acceptable for quantities that are required but are not given.
Physical laws and principles (such as conservation of mass, energy) are applied and reduced to the simplest by the assumptions made. However, the area where the physical law will be applied must be clearly defined and boundary conditions must be determined first. (Application of energy conservation for pressure loss of gas flowing through a pipe)
Unknown properties, which are necessary for the solution of the problem, should be determined from tables and related formulas for known cases.
Manufacturer catalogs are used to find the unknown, formulas in the literature are applied and results are obtained.
7.Inquiry, Verification and Inspection
It is checked that the results obtained are reasonable and match the engineering intuition. In addition, the validity of hesitant assumptions should be checked.
The results should be interpreted after their inference and expressed their importance. Their meanings should be examined.
Solution alternatives should be presented and decided.
When offering solution alternatives, return periods should be determined according to the investment to be made and the gains to be made and additional expenses to be made should be specified. The pros and cons of the solution alternatives should be mentioned. Alternatives should be presented according to these parameters and one of the alternatives should be proposed.
At this stage, one of the solution alternatives is applied and the approximation to the calculated values after the application is tested. If there are parts that can be improved according to the test results, iterative improvements are made and the problem is solved in an optimum way.
