We show that the optimal policy is base-stock and we derive an explicit formula for the optimal base-stock level. For the general n-stage problem, we show that the optimal policy is characterized by state-dependent base-stock levels. In a numerical study, we investigate three heuristic ...
Let’s say we work for a drug company that produces six different products at their plant. Production of each product requires labor and raw material. Row 4 in Figure 27-1 shows the hours of labor needed to produce a pound of each product, and row 5 shows the po...
Optimal PWM: (A) normalized three-level waveform, (B) implementation of optimal PWM, and (C) harmonic spectra of phase and line voltages for SHE-PWM, SHM-PWM, and OPP-PWM. The most common among all optimal PWM techniques is Selective Harmonic Elimination (SHE-PWM). In SHE-PWM, the ...
The resulting mathematical programming formulation determines the optimal level of component reliability and the number of redundant components at each stage. ... Dhingra,K A. - 《Reliability IEEE Transactions on》 被引量: 339发表: 1992年 Comparison of a genetic algorithm and mathematical programming...
The optimal growth model essentially leads to a unique macroeconomic growth path when there is no change in the level of technology attributed to the mechanism of the production function, whether based on omniscient central planning or in a decentralized market economy. The core element of economic...
In this context, system elements can be analyzed at different decomposition levels or they are partitioned at the same level, respectively. The second situation corresponds to the considered case in this work for expressing granularity level of ALSs. Accordingly, the granularity level of assembly ...
A natural application of our approach is the prediction of hierarchies. Indeed, the usual approaches to hierarchical forecasting1 are based on univariate models applied either to the lowest level of the hierarchy (bottom-up) and summed up to match the aggregate forecasts, or to the top-level ti...
The optimal scheduling problem of integrated energy system (IES) has the characteristics of high-dimensional nonlinearity. Using the traditional Grey Wolf Optimizer (GWO) to solve the problem, it is easy to fall into a local optimum in the process of opt
