التحليل الكمي :( انا ضايع ..

[girl.k.s.a]

المشاركة الأصلية كتبت بواسطة khaled.91.11 يعطيكي العافية بس ذحين عندي سؤال أول مسألة هذي من شبتر 1 والا 2 لأني كذا ضيعت + ايش هي Controlleable و Uncontrollable لأنه تري نحن فعلا زي ما قال MohPro ضايعين في المادة اطمني محد حيدقق

لالا أنا مآشيه معاكم حبه حبه من أول شابتر
الأسئلة دي نفس الكتاب بس اختف الارقام لو فهمتوها كويس
+
المسألة تبع الاكسل كآنت آخر شي في الشآبتر
Controlleable يعني أي رقم تقدر تغيرو
Uncontrollable رقم ثابت ما يتغير مثل
( القدرة على انتاج شنطة في يوم واحد كم تساوي ؟)

الـ Uncontrollable هيا القدرة يعني ما نقدر ننتج أكتر منها خلاص العدد ثابت
ما أقدر أزود عليه
أما الـ controllable هوا مثلا عدد ساعات العمل أقدر أزودها لكن القدرة اللي هوا معطيني
اياها ما تتغير

دي التعاريف مهمه كمان وجآت منها

In modeling terminology,
physical replicas are referred to as iconic models

second classification includes models that are physical in form but do not have the
same physical appearance as the object being modeled. Such models are referred to as
analog models

Such models are referred to as mathematical models and are a critical part of
any quantitative approach to decision making

Uncontrollable inputs can either be known exactly or be uncertain and subject to variation.
If all uncontrollable inputs to a model are known and cannot vary, the model is
referred to as a deterministic model


The distinguishing feature of a deterministic model is that the uncontrollable input
values are known in advance

If any of the uncontrollable inputs are uncertain and subject to variation, the model is
referred to as a stochastic or probabilistic model

هادي شروحات للنماذج والكنترولبل والانكنترولبل

وهنا التعاريف راح تكون أسهل بكتييييييييييير وجآمعة لكل شي في الشابتر
أفهموآ التعاريف بس أمشوا علىالتمارين خطوة بخطوة تلقوا نفسكم تمام إن شآء الله

GLOSSARY
Problem solving The process of identifying a difference between the actual and the
desired state of affairs and then taking action to resolve the difference.
Decision making The process of defining the problem, identifying the alternatives,
determining the criteria, evaluating the alternatives, and choosing an alternative.
Single-criterion decision problem A problem in which the objective is to find the “best”
solution with respect to just one criterion.
Multicriteria decision problem A problem that involves more than one criterion; the
objective is to find the “best” solution, taking into account all the criteria.
Decision The alternative selected.
Model A representation of a real object or situation.
Iconic model A physical replica, or representation, of a real object.
Analog model Although physical in form, an analog model does not have a physical
appearance similar to the real object or situation it represents.
Mathematical model Mathematical symbols and expressions used to represent a real
situation.
Constraints Restrictions or limitations imposed on a problem.
Objective function A mathematical expression that describes the problem’s objective.
Uncontrollable inputs The environmental factors or inputs that cannot be controlled by
the decision maker.
Controllable inputs The inputs that are controlled or determined by the decision maker.
Decision variable Another term for controllable input.
Deterministic model A model in which all uncontrollable inputs are known and cannot
vary.
Stochastic (probabilistic) model A model in which at least one uncontrollable input is
uncertain and subject to variation; stochastic models are also referred to as probabilistic
models.

Optimal solution The specific decision-variable value or values that provide the “best”
output for the model.
Infeasible solution A decision alternative or solution that does not satisfy one or more
constraints.
Feasible solution A decision alternative or solution that satisfies all constraints.
Fixed cost The portion of the total cost that does not depend on the volume; this cost
remains the same no matter how much is produced.
Variable cost The portion of the total cost that is dependent on and varies with the volume.
Marginal cost The rate of change of the total cost with respect to volume.
Marginal revenue The rate of change of total revenue with respect to volume.
Breakeven point The volume at which total revenue equals total cost.


لو فهمتوا التعاريف + المسائل يكون خلصتوا شابتر 1 بالسلامة
أرجعوا أقرؤا الموضوع من البداية وشوفوا الشرح وأمسكوا الكتاب معاكم ورآح تمشي أموركم
وركزوآ على الكلمات اللي باللون الأسود في الكتاب لأنها محل أسئلة ..

بالتوفيق لكم ..
