The deterioration cost per unit per cycle.
Hence, the system inventory total cost = ordering cost + inventory holding cost in RW + inventory holding cost in OW + deterioration cost in RW + deterioration cost in OW + shortage cost + lost sales cost + purchasing cost + promotional effort cost.
Here, the total cost ({text{TC}}) of the system is given by ({text{TC}} =) < ordering cost > + < advertisement cost > + < holding cost > + < shortage cost > + < deterioration cost > + < lost sale cost > {text{i}}.
Assuming the automatic tap price in addition to its installation cost is SR 600 and its useful life is 60 months, then, D c (tap deterioration cost) = 600/60 = SR 10 monthly, whereas traditional tap installation cost is only SR 60 and its useful life is 60 months as well so, its monthly deterioration cost is only SR1.
The system efficiency of decentralized supply chain increases with market scale, price sensitivity, deterioration rate, the supplier's cost (including unit production cost, holding cost, and deterioration cost), and service investment efficiency, while decreases with production rate.
We develop a cash-flow based profit maximising Net Present Value (NPV) model without the inventory cost parameters commonly used in this context: unit holding cost, unit backorder cost, unit deterioration cost, and unit lost sales cost.
Corrosion of reinforcement is a serious problem and is the main cause of concrete structures deterioration costing millions of dollars even though the majority of such structures are at the early age of their expected service life.
A system total annual cost can be modeled as follows: T_{text{c}} = W_{text{c}} + D_{text{c}} + M_{text{c}} (10 where T c is the Annual total cost, W c is the Annual flushwater cost, Dc is the Annual deterioration cost (Installation cost divided by its useful life in years), M c is the Annual maintenance cost.
The deterioration cost (IDC) during the period [0, T] is begin{aligned} mathrm{IDC} &= d_{mathrm{c}}left[ q-amu -int _{0}^{t_{1}}left[ a+bleft( t-mu right) right] mathrm{d}tright] nonumber &= d_{mathrm{c}}left[ q-amu -left( a-bmu right) t_{1}-frac{bt_{1}^{2}}{2}right].
In fact, it's just the opposite: WIPP and two German-based DGRs have brought about disaster with radioactive leaks and structural deterioration costing billions of euros in remediation.
