I and J represent inventory levels for each type of products.
Based on the above description, during the time interval ( [0,,,mu_{2} ] ), the inventory level in RW is decreasing only due to demand rate and the differential equation representing the inventory status is given by.
A buffer may represent an inventory and a converter may represent orders.
In a just-in-time (JIT) system, kanban number and size represent the inventory level of work-in-process (WIP) or purchasing parts.
The index i represents an inventory point, ε represents the remaining errors, a is the model's intercept, which is to be estimated, and f1,…, f4 are non-linear smoothers to be fitted.
The reminder of this paper is organized as follows: In "Problem description", first we represented an inventory model and then a mathematical model has been constructed for competitive location.
Thus, the differential equation given below represents the inventory status: frac{{{text{d}}q_{text{r}} (t)}}{{{text{d}}t}} + beta,q_{text{r}} (t) = - D,quad mu_{2} le t le t_{text{r}}.
Weather effects on forest productivity are not normally represented in inventory-based models for carbon accounting.
However weather effects on forest productivity are not currently represented in inventory-based models such as CBM-CFS3 used in national forest C accounting programs.
Footprint cells with green tones are below the median Mahalanobis distance at site and are relatively well represented by inventory-based sample plots, while footprint cells with red tones are above the median Mahalanobis distance for each site and are less well represented.
