Brake components will boom more in developing countries in comparison to developed countries due to higher demand rate
"The expected demand rate
of sacrifices during the three days is expected to be between 5,000 to 10,000 heads of cattle or more," he said.
al (2015) considered a production inventory model for deteriorating items with ramp type demand rate
where deterioration rate was represented by a two-parameter Weibull distribution and solved under fuzzy environment to evaluate the optimum solution of the model.
The traditional economic order quantity (EOQ) model was designed to solve the problem encountered by buy-in and sell-out dealers, who determine the inventory standard of goods at the beginning of each period in response to the given demand rate
of goods, thereby minimizing the cost per unit time.
Furthermore, we can identify that the N(t) is represented as a general queuing system of which arrival rate is data demand rate
and the service time is the replenishment time, since the arrival rate [alpha](t) and the departure rate [gamma](t) of the N(t) are defined by random variables which are correspondent to the data demand rate
and the replenishment rate of the DPS.
However, it is impossible for deteriorating items that the demand rate
increases continuously during their full life cycle.
As frequently observed in the retail industry, the demand rate
is an increasing function of the current inventory level.
Abdullah Al-Sheheri, a dealer in the real estate market said the Royal Decree will develop several lands for housing projects in different regions which will increase the supply ratio against the demand rate
. "Housing unit prices will stand to return to the levels they were 15 years ago," he stated.
In addition to the new products introduction, holiday-related products, such as those for Christmas season, are experimentally shown to fit this type of demand rate
. On the other hand, when the market demand is better, the supplier will provide a higher production rate; if the market demand is shrinking, the supplier will reduce the production rate.
Giri and Chaudhuri  developed deterministic model of perishable inventory with stock-dependent demand rate
and nonlinear holding cost and proved that the nonlinear holding cost affected the total average cost.
Therefore, the main decision variables in this system are Q and r which depend on safety stock considerations in addition to demand rate
and lead times.
