Essay - System Operational Feasibility Great Deal of Time and Intellectual Resources...

System Operational Feasibility great deal of time and intellectual resources go into the conceptual design stage of a systems engineering process once ***** need is clearly defined by the end-user. However, this initial development step is a moot point if the product ***** not operationally feasible, which means, according to Benjamin Blanchard in his book Systems Engineering ***** Analysis, "that the system will perform as intended in an effective and efficient manner for as long ***** necessary."

In order for the systems engineer ***** determine operational feasibility, it is necessary to properly integrate the design-related specialties such as reliability, maintainability, human factors ***** supportability.

Reliability is one of ***** most important design elements, since it confirms or denies the long-term use of the product without major maintenance and repair. Unreliable ***** do ***** meet the original project goals ***** lead to unnecessary expenditures of valuable *****. Simply stated, "reliability ***** the probability ***** a system or ***** will ***** in ***** satisfact*****y ***** for a given period of time when used under spec*****ied operat*****g conditions." The four elements noted—probability, per*****mance in a s*****tisfactory manner, time and specified operation conditions—are highly significant when deciding on system or product reliability.

Probability can be defined as the quantitative expression representing a fraction or a percent specifying ***** number ***** times that one can expect an event to occur in a total number of trials. F***** example, if the probability of survival of a product for 150 hours is 80 percent (or 0.*****), the user c***** expect ***** it ***** function correctly ***** ********** least 150 ***** 80 out of 100 times.

***** second factor or element, satisfactory performance, def*****es what specific criteria ***** to be established in order to consider the item to ***** *****. The considerations *****clude both qualitative ***** quantitative requirements. Time is very important, since it represents how long the product or system will be functioning at desired ***** levels. Reliability ***** *****ten designated in terms of mean time between failure (MTB*****) ***** ***** time ***** failure (MTTF).

Operating conditions include environment such as temperature and humidity, degree of vibration ***** amount of shock. These conditions are not only while ***** unit is operational, but also ***** it is resting in a nonuse or stor*****ge mode. Handling conditions, such ***** the heat of the truck that is transporting the product, can have a ***** impact on ***** well the system works.

***** other all-***** aspect of a ***** or system's ***** feasibility is *****. This c*****sists ***** the ease, accuracy, safety and economy in ***** performance of the maintenance functions. If a unit is difficult to repair, ***** costs of a process can get completely out of hand. While the item ***** ***** functioning, interrelated *****es stop and labor is at a st*****still. If ***** system works well when it is operational, but causes significant *****wntime, ***** is not functioning as expected.

Maintainability is inherent in ***** product design. It ***** the ability of an item to be ma*****tained, whereas
