Application of Nested Cost Optimization Models to Tspd

چکیده
Through the analysis of Travelling Salesman Problem with Pickup and Delivery (TSPD) in the related research, two kinds of logistics systems including whole logistics system and partial logistics system under one-to-many logistic network are considered. And mathematical model is set up, then, nested cost optimization model is set up in order to meet the constraint condition of nested order cycle time. According to an application pickup and delivery instance of iron and steel in one factory, by using the method of adaptive response surface in Hyperstudy software, the initial solutions are figured out, and further the optimum direction of iteration is found so as to obtain the optimum solution.

Robustness-based portfolio optimization under epistemic uncertainty
In this paper, we propose formulations and algorithms for robust portfolio optimization under both aleatory uncertainty (i.e., natural variability) and epistemic uncertainty (i.e., imprecise probabilistic information) arising from interval data. Epistemic uncertainty is represented using two approaches: (1) moment bounding approach and (2) likelihood-based approach. This paper first proposes a ...
متن کاملA new method for fuzzification of nested dummy variables by fuzzy clustering membership functions and its application in financial economy
In this study, the aim is to propose a new method for fuzzification of nested dummy variables. The fuzzification idea of dummy variables has been acquired from non-linear part of regime switching models in econometrics. In these models, the concept of transfer functions is like the notion of fuzzy membership functions, but no principle or linguistic sentence have been used for inputs. Consequen...
متن کاملDesign of High-Efficiency and Low-Cost Six-Phase Permanent Magnet Synchronous Generator for Direct-Drive Small-Scale Wind Power Application
Permanent magnet synchronous generators (PMSG) have a huge potential for direct-drive wind power applications. Therefore, optimal design of these generators is necessary to maximize their efficiency and to reduce their manufacturing cost and total volume. In this paper, an optimal design of a six-phase 3.5 KW direct-drive PMSG to generate electricity for domestic needs is performed. The aim of ...
متن کاملDevelopment of PSPO Simulation Optimization Algorithm
In this article a new algorithm is developed for optimizing computationally expensive simulation models. The optimization algorithm is developed for continues unconstrained single output simulation models. The algorithm is developed using two simulation optimization routines. We employed the nested partitioning (NP) routine for concentrating the search efforts in the regions which are most like...
متن کاملAntitumor activity of a Trans-thiosemicarbazone schiff base palladium (II) complex on human gastric adenocarcinoma cells
The development of transition-metal-based antitumor drug candidates increases the metallopharmaceuticals study dramatically. Two trans-thiosemicarbazone-based, Schiff base palladium (Pd) (II) complexes, DMABTSPd (TSPd) and DMABPTSPd (PTSPd), were prepared and characterized as described in our previous study. Here, we investigated whether the two complexes have antitumor effect on human gastric ...
